Firmly implement the strategy of expanding domestic demand and accelerate the release of consumption potential-the operation of consumer market and the work of promoting consumption in 2020

2020 is an extraordinary year. Faced with the severe impact of the complicated domestic and international environment, especially the COVID-19 epidemic, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the Ministry of Commerce has conscientiously implemented the decision-making arrangements of the CPC Central Committee and the State Council, firmly implemented the strategy of expanding domestic demand, coordinated epidemic prevention and control and consumption promotion, promoted consumption recovery and potential release, promoted the formation of a strong domestic market, and provided support for building a new development pattern. Consumption showed a steady recovery trend. In August, the growth rate of social zero total turned from negative to positive, and then it maintained positive growth for five consecutive months, showing the strong resilience and vitality of China’s domestic demand market.

I. Operation of the Consumer Market in 2020

The epidemic in COVID-19 has caused unprecedented impact on the consumer market. In January and February, the total amount of social welfare dropped by 20.5% year-on-year, the biggest drop since the reform and opening up. With the major strategic achievements in epidemic prevention and control in China, policies and measures such as expanding domestic demand and promoting consumption have gradually taken effect, and the consumer market has steadily recovered and continued to pick up. In the fourth quarter, the total amount of social zero increased by 4.6% year-on-year, and the growth rate was 3.7 percentage points faster than that in the third quarter; Consumption boosted economic growth by 2.6 percentage points, up 1.2 percentage points from the third quarter. The total social zero in the whole year was 39.2 trillion yuan, down 3.9% from the previous year, and the decline was 7.5 percentage points narrower than that in the first half of the year; The final consumption rate is 54.3%, and consumption is still the ballast stone for economic and stable operation. Mainly presents the following characteristics:

First, commodity consumption continued to pick up and the consumption structure was constantly optimized. The annual retail sales of commodities decreased by 2.3%, which was 6.4 percentage points narrower than that in the first half of the year. Among them, it increased by 5.2% in December, and it has been growing for six consecutive months; Among the 15 categories of commodities of units above designated size, 14 categories are growing, and the growth rate of 7 categories exceeds 10%, among which upgraded commodities such as communication equipment, gold, silver and jewelry, and household appliances are increasing by 21%, 11.6% and 11.2% respectively. Green, smart and healthy goods are selling well, and Guochao brand is sought after. The annual automobile sales volume was 25.31 million, ranking first in the world for 12 consecutive years, among which the sales volume of new energy vehicles was 1.367 million, an increase of 10.9%; The shipment of 5G mobile phones was 163 million units, accounting for 52.9% of the total mobile phone shipments; The sales of some e-commerce platforms such as large-screen smart TVs, large-capacity fresh-keeping refrigerators, sterilization air conditioners, washing and drying machines, disinfection kitchen appliances, fitness equipment, flowers and other products have more than doubled.

Second, catering consumption recovered steadily, and service consumption gradually picked up. The annual catering revenue decreased by 16.6%, which was 16.2 percentage points narrower than that in the first half of the year. Among them, it increased by 0.4% in December, and the growth rate rebounded by 1 percentage point from last month, and the consumption scale basically returned to the same period of last year; The catering revenue of units above designated size increased by 3.6%, which was positive for four consecutive months. The majority of catering enterprises actively responded to the impact of the epidemic, enriched and upgraded dishes, innovated online and offline business models, and accelerated the development of online ordering and semi-finished products take-out. The consumption of tourism, culture, entertainment and other services has gradually picked up. The number of national tourists in the "Eleventh" Golden Week has recovered to 79% over the same period of last year, and the degree of recovery has increased by 25.5 percentage points compared with the "May 1" holiday; The average monthly movie box office in the fourth quarter increased by 37% compared with the average monthly level in August-September.

Third, new consumption has developed rapidly, and online and offline integration has accelerated. Online shopping, non-contact distribution, live delivery, online education, online medical care, online entertainment, online fitness and other new formats and new models have developed rapidly, which have played an important role in epidemic prevention, helping to resume work and production, promoting consumption recovery and stabilizing the economy. In 2001, the online retail sales of physical goods reached 9.8 trillion yuan, up 14.8% against the trend, accounting for 24.9% of the total social zero. The express delivery business reached 83.36 billion pieces, and the live broadcast of e-commerce exceeded 20 million. China has become the largest online retail market in the world for eight consecutive years. Physical retail enterprises accelerate digital transformation, vigorously develop online sales and home-to-home business, and accelerate online and offline integration. Large-scale e-commerce platforms actively develop C2M reverse customization, empower upstream industries, and carry out flexible manufacturing to meet personalized and diversified consumer needs.

Fourth, the market supply has been continuously optimized, and consumption abroad has accelerated its return. The quality of domestic goods has been continuously improved, the import channels have been continuously broadened, the duty-free shopping policy has been continuously improved, and the epidemic situation has affected residents’ exit, so the return of consumption abroad is obvious. The annual import volume of consumer goods reached 1.57 trillion yuan, up 8.2% year-on-year, 8.9 percentage points higher than the overall growth rate of imports; It accounted for 11% of imports, up about 1 percentage point from the previous year. Among them, the import of meat, jewelry and cosmetics increased by more than 30%, and the import of luggage and watches increased by more than 20%. Cross-border e-commerce retail imports continued to maintain rapid growth. Hainan implemented the new policy of duty-free shopping on outlying islands, and the annual sales of duty-free shops reached 32.74 billion yuan, an increase of 1.27 times over the previous year.

Fifth, the urban and rural markets resumed simultaneously, and some areas turned from negative to positive. The retail sales of urban and rural consumer goods decreased by 4% and 3.2% respectively in the whole year, which was 7.5 and 7.7 percentage points narrower than that in the first half of the year. The rapid development of rural e-commerce has promoted the steady recovery of rural consumption, unblocked the upward channels of agricultural products, and helped to get rid of poverty. From January to November, the rural online retail sales reached 1.59 trillion yuan, up 9.5% year-on-year; The online retail sales of agricultural products reached 359.35 billion yuan, an increase of 30.2%. In some areas, the total amount of social welfare in the whole year achieved positive growth, among which Guizhou, Jiangxi and Anhui increased by 4.9%, 3.0% and 2.6% respectively, while Chongqing, Hainan and Shanghai increased by 1.3%, 1.2% and 0.5% respectively. In other areas, the decline narrowed in different degrees, with the decline in Heilongjiang, Hubei and Shanxi narrowing by 13.6, 13.3 and 12.3 percentage points respectively compared with the first half of the year.

Sixth, consumer prices are generally stable, and the increase in food prices has dropped. Consumer prices rose by 2.5% in the whole year, down 0.4 percentage points from the previous year. The core price index excluding food and energy rose by 0.8%, which remained within a reasonable operating range. Grain production has achieved another bumper harvest, pig production has accelerated its recovery, and the increase in food prices has dropped significantly. In December, food prices rose by 1.2% year-on-year, which was 19.4 percentage points lower than that in January, among which pork prices fell by 1.3% year-on-year.

Second, the main work carried out in 2020

In 2020, the Ministry of Commerce will resolutely implement the decision-making arrangements of the CPC Central Committee and the State Council, firmly implement the strategy of expanding domestic demand, coordinate epidemic prevention and control and consumption promotion, and take various measures to promote consumption recovery and potential release. Mainly carried out the following work:

The first is to increase urban consumption. Deepen the renovation and upgrading of pedestrian streets, confirm five national demonstration pedestrian streets, and identify 12 pedestrian streets to carry out the second batch of pilot projects. In 2020, the passenger flow and turnover of the pilot pedestrian streets in the "Eleventh" Golden Week will increase by 14.3% and 19.2% respectively. Accelerate the cultivation and construction of international consumption center cities, and guide key cities to try first and explore actively. Efforts will be made to promote the branding, chaining and intelligent development of convenience stores. In the first three quarters of 2020, 12,000 brand chain convenience stores were opened nationwide, with a total of 167,000 stores, and sales increased by about 5% year-on-year.

The second is to expand rural consumption. Promote e-commerce into rural areas, expand coverage, improve the three-level logistics distribution system in counties and villages, guide and support large-scale circulation enterprises to sink the supply chain with the focus on towns and villages, and improve the two-way circulation efficiency of agricultural products into cities and industrial products to the countryside. In 2020, e-commerce will support 235 new demonstration counties and 1,338 counties, and 2,120 county-level e-commerce public service centers and logistics distribution centers and 137,000 village-level e-commerce service stations will be built. Improve the supply chain of agricultural products, support the construction of primary processing facilities and cold chain logistics distribution centers of agricultural products, improve the circulation efficiency of agricultural products and reduce the circulation cost.

The third is to stabilize commodity consumption. We will promote the introduction of policies and measures to stabilize automobile consumption and boost mass consumption, promote the development of the used car trading market, issue the Detailed Rules for the Implementation of the Management Measures for the Recycling of Scrap Motor Vehicles, carry out activities of new energy vehicles going to the countryside in conjunction with relevant departments, encourage qualified areas to increase the number plate of automobiles, implement subsidies for new car purchases, relax restrictions on pickup trucks entering the city, and release automobile consumption potential. In conjunction with relevant departments, we will introduce policies and measures to improve the recycling system of used household appliances, promote the renewal of household appliances consumption, guide local governments to carry out activities such as household appliances consumption festival and household appliances benefiting the people, encourage qualified areas to implement subsidies for green smart household appliances, carry out trade-in of household appliances, and promote household appliances consumption.

The fourth is to develop service consumption. In conjunction with relevant departments, formulate guiding opinions on the prevention and control of catering service epidemic situation, actively coordinate the introduction of tax reduction and fee reduction, rent reduction and other support policies, and promote the resumption and development of catering industry. Improve norms and standards, and resolutely stop food and beverage waste. Carry out a series of activities of "Thousands of Foods and Foods" to boost food and beverage consumption. Improve the credit information platform for domestic service, and introduce support policies with relevant departments to consolidate and expand the achievements of domestic poverty alleviation.

Fifth, innovation promotes consumption activities. Together with the Central Radio and Television General Station, the National Consumption Promotion Month was organized, and more than 3000 large-scale activities were organized in more than 200 cities. During the activities, the total consumption in the country reached 4.24 trillion yuan, an increase of 8.7% from the previous month. The second "Double-product Online Shopping Festival" was held, achieving sales of 182.5 billion yuan, up 1.37 times compared with the first one, driving the national online retail sales to exceed 430 billion yuan in the same period, up 20.8% year-on-year. Strengthen local experience summary and publicity, and guide all localities to do a good job in promoting consumption at the end of the year and the beginning of the year according to local conditions.

III. Work considerations for 2021

In 2021, the development of consumer market not only has many favorable conditions and positive factors, but also faces many difficulties and challenges. The Ministry of Commerce will adhere to the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the New Era, thoroughly implement the spirit of the Fifth Plenary Session of the 19th CPC Central Committee and the Central Economic Work Conference, base itself on the new development stage, implement the new development concept, build a new development pattern, adhere to the strategic basis of expanding domestic demand, make efforts to open up blocking points, fill shortcomings, comprehensively promote consumption, improve the modern circulation system, effectively enhance the basic role of consumption in economic development, and continuously meet the people’s growing needs for a better life. Focus on the following four aspects:

The first is to improve the traditional consumption level. Promote the consumption of commodities, promote the transformation of consumer goods such as automobiles from purchase management to use management, deepen the "streamline administration, delegate power, strengthen regulation and improve services" reform in the field of automobile circulation, and encourage qualified areas to carry out the trade-in of automobiles, household appliances and furniture. Expand service consumption, develop community life service, boost catering consumption, and promote the upgrading and expansion of domestic service. Develop rural consumption, expand the coverage of e-commerce in rural areas, strengthen the construction of logistics sites in villages, encourage qualified circulation enterprises to sink channels, and support the construction of township business centers.

The second is to accelerate the cultivation of new consumption. Support traditional commercial enterprises to use information technologies such as 5G, big data and Internet of Things, accelerate digitalization, intelligent transformation and cross-border integration, and better meet personalized and customized consumer demand. Encourage the development of new consumption patterns and new formats and promote online and offline integration. Improve the new consumption development environment, improve relevant norms and standards, and strengthen the construction of the credit system.

The third is to optimize the consumption upgrade platform. Accelerate the cultivation and construction of international consumption center cities, steadily and orderly promote the pilot reform and upgrading of pedestrian streets, and create an important carrier to lead the upgrading of urban consumption. Create a new community convenience life circle, promote convenience service facilities into the community, and build and transform a number of convenience service facilities such as breakfast shops and vegetable markets to make urban life more warm. Run the 4th Import Expo and the 1st China International Consumer Goods Expo well.

The fourth is to improve the modern circulation system. Promote the construction of a modern commercial and trade circulation system, unblock the "artery" of the circulation network, open up the "microcirculation" of urban and rural circulation, further improve the circulation efficiency, reduce the circulation cost, and unblock the domestic circulation. Promote the integration of domestic and foreign trade, build a high-level open platform, improve the ability to make overall use of the two resources in the domestic and international markets, and promote the domestic and international double cycle.

　　"Graduation is just around the corner, and there will be less teachers in my ears in the future ‘ Nagging ’ , but also to maintain good credit habits, repayment on schedule to safeguard personal credit … …” John young, a teacher of the Student Financial Assistance Management Center of xidian university (hereinafter referred to as "Xidian"), gave careful instructions to the students who had completed the loan graduation confirmation.

　　In order to implement the requirements of the Notice of the Ministry of Education on Vigorously Carrying out the Theme Activities of Sponsoring Honesty Education for College Students in 2023, the school recently organized the theme activities of "Honesty Publicity and Education Month", and continued to carry out a series of financial knowledge and loan repayment knowledge propaganda among students, so as to escort the successful graduation of loan students.

　　An interview with the reporter of Zhongqingbao Zhongqingwang was informed that, while insisting on handling national student loans for students’ places of origin and campus, the school specially set up interest-free student loans on campus — — For more than 30 years, it has played a leading role in educating people, such as helping the poor, promoting learning and strengthening ambition, and greatly improved the effect of aiding and educating people with precise funding.

　　In 1986, Xidian set up an on-campus loan scholarship through self-financing, which became an effective supplement to scholarships, grants, student loans and other funded projects, enabling students with financial difficulties to study and live at school with peace of mind. When the school loan scholarship was first established, it was mainly for college students with financial difficulties, and each student could apply for no more than 250 yuan per academic year. After applying for the on-campus loan scholarship, there is no need to repay it during the study period.

　　After more than 30 years, the scale of the school loan scholarship project has been continuously expanded, the scope and objects of funding have been adjusted and improved many times, and it has gradually developed into the current interest-free school loan, and the funding standard has also been raised to 2,000 yuan per academic year.

　　"In response to on-campus loans, the school has successively introduced a series of management systems." You Wujing, deputy director of the Student Affairs Office of Xidian University, said: In the early stage of the project application, the counselor will strengthen the visit and arrangement, focusing on students in ethnic areas, special difficulties or those who are trapped due to unexpected situations, and have a one-on-one talk to understand the needs and ensure the accuracy and appropriateness of the funding. During the evaluation of each class, a student financial assistance group will also be set up for democratic evaluation to ensure that no one is missed.

　　In order to better publicize the subsidy policy, the school has also set up a team of teachers’ subsidy work and a team of students’ subsidy publicity ambassadors, combining online and offline, entering the classroom and going deep into the dormitory to publicize the pre-loan policy. Over the past 30 years, Xidian has issued more than 50 million yuan of interest-free student loans and subsidized more than 60,000 students, and the project has the ability of self-circulation.

　　With the development of economy and society, the interest-free student loan projects in the school have been constantly adjusted and enriched, from "guarantee" to "development", and an all-round and diversified student financial aid system of "award, loan, help, supplement, diligence, reduction and compensation" has been established.

　　In 2016, the application conditions for interest-free student loans on campus were relaxed, and all undergraduates can apply for it, which can be used for personal interest and ability improvement training, summer social practice, participation in academic conferences and various scientific research and innovation activities. The school also stimulates the endogenous motivation of students’ ability improvement through the method of loan relief on campus.

　　"At the stage when the on-campus loan is only for students with financial difficulties, the school gives 10% reduction to the loan students, which is inclusive." You Wujing said that now, if students with financial difficulties are identified, they will continue to be given relief. At the same time, if students are outstanding in doing good deeds, helping others, academic competitions, innovation and entrepreneurship, academic research, engineering practice, etc., they will also be given a certain percentage of relief. For graduates who are employed in key units or grass-roots units, enlisted for compulsory military service or recruited as non-commissioned officers, this school policy is also applicable, and full relief will be given when repayment is made. Encouraged by the new measures, 209 students have successfully applied for school loan relief in the past seven years, with the amount of relief reaching more than 260,000 yuan.

　　In order to facilitate repayment channels, the school has developed a "repayment self-service system". Before graduation, students log in through identity authentication, and after checking that the repayment information is correct, they can scan the code for self-service repayment, and the whole process takes only 3 minutes. On the eve of graduation every year, the school will also carry out the theme education of "Integrity Publicity Month", and carry out "honesty and trustworthiness" discussions in various forms, such as issuing integrity proposals, establishing integrity files, and selecting stars of integrity and self-improvement, so as to guide students to stand on their own feet and share opportunities for life.

　　"Warm and powerful" is the evaluation of JiNing, a graduate of Xidian University in 2022, on the interest-free student loan policy in his alma mater. During his school days, he applied for on-campus loans and national student loans for study and life. After four years of struggle, he was sent to Peking University for postgraduate study. "The subsidy policy of the state and schools is the biggest backing for students with financial difficulties from families, which gives me the confidence to work harder in my studies." JiNing said.

　　It is reported that Xidian has successively issued the "Implementation Plan for Improving the Quality of Sponsored Education" and the "Implementation Plan for Implementing the Top Ten Education Systems" to transform the school’s red cultural resources into educational advantages. At the same time, we will implement the action plan of development-oriented financial aid to educate people, and promote development-oriented financial aid to educate people with four plans: practical education, interest enhancement, skill enhancement and care and care, effectively combining poverty alleviation with wisdom and ambition.

　　In the past three years, the further education rate and employment rate of students assisted by the school are higher than those of undergraduates. At the same time, a group of Xidian students have emerged who donated scholarships to left-behind children and rural primary school students, donated hematopoietic stem cells for free, and used their knowledge to develop relevant systems to help fight crime.

　　"In the next step, the school will continue to optimize and adjust the school-funded projects according to the actual needs of students, helping students with financial difficulties in their families to study without worry, live a secure life, realize their dreams and live up to their youth." The relevant person in charge of the Xidian Student Financial Assistance Management Center said.

　　Zhongqingbao Zhongqingwang reporter Sun Haihua Source: China Youth Daily

　　In the past few days, some citizens in Zhongyuan District of Zhengzhou have reported that water is boiled with tap water at home, and the scale is more than before, and the water is slightly salty. What is going on? Is it related to the switching of the Yellow River water source in Shiyuan Waterworks? Will it have adverse effects on human health? On April 12th, the reporter specially came to Zhengzhou Stone Buddha grit chamber and Shiyuan Water Plant to answer these questions for you.

　　The Shiyuan Water Plant switched the Yellow River water, and the staff took water from the stone Buddha grit chamber for testing.

　　On the morning of April 12, the reporter came to Zhengzhou High-tech Zone. After the staff stationed here opened an iron gate, a large area of water came into view. It is the main water source of Zhengzhou Shiyuan Water Plant-the stone Buddha grit chamber.

　　On the southeast bank of the stone Buddha grit chamber, two workers from Zhengzhou Monitoring Station of the National Urban Water Supply Quality Monitoring Network are taking water, and then they will return to the laboratory to test the water quality of the raw water of the Yellow River.

　　According to the staff of Zhengzhou Water Supply Company, in 2002, the open channel of Mangshan main water conveyance canal was transformed into a concealed pipe project in Zhengzhou City, and the stone Buddha grit chamber was excavated. The stone Buddha grit chamber covers an area of 420,000 square meters, with a depth of 5 meters, a total storage capacity of 1.5 million cubic meters and an effective storage capacity of 1.25 million cubic meters. It plays a role in pre-settling, water storage and regulation during the whole water supply process. The raw water of the Yellow River is extracted from Mangshan irrigation station, and flows into this area for pre-sedimentation through more than 10 kilometers of underground pipes, then pressurized by Shifo Pumping Station, and directly transported to Shiyuan Waterworks through a 7-kilometer-long water pipeline.

　　When visiting the Shiyuan Water Plant in Zhengzhou, the reporter saw that the stone Buddha grit chamber was directly transported to the Shiyuan Water Plant through a 7-kilometer-long water pipeline. In Shiyuan Waterworks, the Yellow River water delivered from the grit chamber is introduced into a huge pool by the water intake pump station. After being processed by powdered activated carbon, pre-ozone, coagulant, sodium hypochlorite, coagulant aid, etc., it enters the clean water tank in the mechanical mixed folded plate advection sedimentation tank, and then enters the ozone contact tank, activated carbon filter and sand filter, and finally enters the water distribution network through the water supply pump station and flows into thousands of households.

　　In the pump room of the water plant, the staff of the resident laboratory of the water quality monitoring center of Zhengzhou Water Supply Company also carried out water intake testing for tap water sent to thousands of households.

　　After boiling water in some residents’ homes, the scale increases and tastes slightly salty. Why?

　　Since all the indicators of tap water are normal, why do some citizens report that in the past half month, the scale has increased after boiling water at home, and the water is slightly salty?

　　Lou Ning, director of Zhengzhou Shiyuan Water Plant, said that at 7: 55 am on March 28, the raw water pipeline of Shiyuan Water Plant, which transported the water source of South-to-North Water Transfer Project, leaked. Shiyuan Water Plant closed the water inlet valve of the water source of South-to-North Water Transfer Project in the factory area and urgently started the Yellow River water source for water supply.

　　After Shiyuan Waterworks was switched from South-to-North Water Transfer Project to Yellow River Water, the anion content in the water changed due to the difference between the two water bodies. For example, the chloride content of Danjiang water is below 10mg/L, and the chloride content of Yellow River water is 80-90 mg/L. Because of the increase of chloride content, there will be a slightly salty taste in the water. However, this change can only be recognized by people who are relatively sensitive to taste. For daily cooking, making tea and drinking coffee has little effect. "The national" Hygienic Standard for Drinking Water "stipulates that the limit of chloride is not higher than 250mg/L, and the test results of the Yellow River water source fully meet the national standards, so citizens can rest assured to drink it." Lou Ning said.

　　Why does the scale and floating objects in the water increase? Lou Ning explained that, generally speaking, natural water bodies have hardness, and the Yellow River water has high hardness. Its main components are calcium and magnesium, which exist in the form of calcium bicarbonate and magnesium bicarbonate in water. When heated, it will become magnesium carbonate or calcium carbonate suspension or sediment, which is commonly known as scale.

　　Among them, the indexes of magnesium carbonate, calcium carbonate and other substances in the South-to-North Water Diversion Project of Shiyuan Waterworks are kept at about 140mg/L, while the indexes of magnesium carbonate, calcium carbonate and other substances are kept between 300 mg/L and 320 mg/L after switching to Yellow River water. However, the detection results of the above indexes are all within the limit of 450mg/L stipulated in the National Hygienic Standard for Drinking Water, so it is harmful to human body.

　　"In the past, Zhengzhou people always ate Yellow River water, but now they eat Danjiang water from the South-to-North Water Transfer Project and suddenly eat Yellow River water, so this change will happen." Lou Ning said that the water supply area of Shiyuan Waterworks is mainly to the west of Beijing-Guangzhou Railway, to the south of Jinshui Road (west extension line), to the east of West Third Ring Road and to the north of South Third Ring Road. Therefore, only the citizens in this area may be affected.

　　How to ensure the water quality safety after the Shiyuan Waterworks is switched to the Yellow River water source?

　　The reporter learned that on March 28, after the raw water pipeline of the South-to-North Water Transfer Project leaked, Zhengzhou Urban Management Bureau organized the first time to carry out excavation inspection on the leaking place, and found that there were bulges and leaks in the pipeline, and other places were suspected of leaking. Zhengzhou Urban Management Bureau coordinated the ownership of the pipeline, and the municipal water conservancy department seized the time to organize emergency repair. At present, the Zhengzhou water conservancy department is still repairing the damaged pipeline, and the specific completion time is temporarily unknown.

　　How to ensure the water quality safety after the Shiyuan Waterworks is switched to the Yellow River water source? Wu Xinping, director of the Water Quality Monitoring Center of Zhengzhou Water Supply Company, said that according to the requirements, Zhengzhou Monitoring Station conducted weekly tests on 11 indicators such as permanganate index, ammonia nitrogen (in N), chemical oxygen demand and petroleum for the three surface water sources of Taohuayu Yellow River Diversion Gate, Shifo grit chamber and raw water of Shiyuan Water Plant. Twenty-nine water quality tests were conducted on three surface water sources every month, and all water quality indexes met the Class III water standard of the National Environmental Quality Standard for Surface Water (GB3838-2002)Ⅲ).

　　Zhengzhou monitoring station tested 42 indexes of the factory water and the end water of the pipe network in Shiyuan Waterworks. Carry out seven pipe network monitoring for the pipe network monitoring points in the region; After testing, all the measured indexes meet the limit requirements of the National Hygienic Standard for Drinking Water (GB5749-2006).

　　During the water source switching, the laboratory of water quality monitoring center of Zhengzhou Water Supply Company in Shiyuan Waterworks carried out process simulation coagulation and stirring experiments and chlorine requirement experiments on raw water entering the factory to find the best dosage of coagulant and guide the production process to add chemicals reasonably. The raw water entering the factory, the outlet of sedimentation tank, the outlet of carbon filter, the outlet of sand filter and the outlet of factory water of Shiyuan Water Plant were tested at least twice a day. The vehicle of water purification agent must be inspected to ensure that the water purification agent is qualified.

　　"From the current situation of water quality testing in the city, the water quality meets the requirements of the National Hygienic Standard for Drinking Water. Zhengzhou Water Supply Company will optimize the water treatment process, strengthen the testing of public water supply in Zhengzhou City, and ensure that the water quality of urban water supply is safe and qualified. Please feel free to drink. " Wu Xinping said.
