Sewage treatment plant operation problems represented by "excessive influent lead to excessive effluent" have always been the focus and pain point of the industry. During the two sessions this year, the operation of the sewage treatment plant was once again mentioned as an important position by the deputies of the National People's Congress, and it became a topic of widespread concern and heated discussion at the two sessions. Cheng Hanfei, a representative of the National People's Congress, chief expert of China Metallurgical Huatian Engineering Technology Co., Ltd., and president of the Water Environment Technology Research Institute, included the problem of the benign operation of the sewage treatment plant.

One month ago, the fourth sewage treatment plant in Qinhuangdao City of Interchina Water had been in an unstable state due to its operation in recent years. Every year, the effluent exceeded the standard discharge. It was forcibly taken over by the Qinhuangdao City Government on April 20. In response to the incident, China Water Net reported on the incident as soon as possible. As soon as the article was published, it quickly triggered widespread heated discussions in the industry (for details, please click: Behind the forced takeover of the 818 Zhongzhong Water Treatment Plant by the government).

It is not difficult to see that the operation problems of sewage treatment plants represented by "excess inflow of water leading to excess of effluent" have always been the focus and pain point of the industry.

In recent months, the outbreak and continuation of the new crown pneumonia epidemic has become a major public health event of international concern. Sewage treatment is a basic public service that guarantees the normal operation of society, and the operation of sewage treatment facilities that undertake the task of treating millions of households has undoubtedly become the focus of attention in the industry. During the two sessions this year, the operation of the sewage treatment plant was once again mentioned as an important position by the deputies of the National People's Congress, and it became a topic of widespread concern and heated discussion at the two sessions.

The four proposals of Cheng Hanfei, the representative of the National People's Congress, the chief expert of MCC Huatian Engineering Technology Co., Ltd., and the president of the Water Environment Technology Research Institute include the healthy operation of the sewage treatment plant:

Suggestion 1: Improve the assessment methods and content of rural sewage treatment systems

Recommendation 2: Improve the construction and operation and maintenance of rural agricultural power grids

Recommendation 3: Ensure the benign operation of urban sewage treatment plants

Recommendation 4: Regarding the "14th Five-Year Plan" Water Ecological Environment Protection Plan

Cheng Hanfei said that the normal operation of urban sewage treatment plants is essential to ensure the quality of the water environment and the health and safety of the people. With the sudden emergence of new coronary pneumonia, the staff of sewage treatment plants across the country overcome various difficulties and stick to their posts to ensure 24-hour uninterrupted operation, which reflects their responsibility and responsibility. However, the factors restricting the healthy operation of urban sewage treatment plants cannot be ignored. Mainly include: the water inflow exceeds the capacity of the sewage treatment plant itself, the sludge disposal has not been effectively solved, the environmental protection responsibility is unlimitedly expanded, the sewage treatment fee is in arrears, and the implementation of tax policies is not uniform.

In an interview with China Water Network, a sewage plant operator once pointed out that the collection range of the pipe network, the living habits of the residents in the collection area, the production rules of the enterprise, the refurbishment and re-planning of the pipe network, etc. will affect the quality of the water entering the sewage plant Water volume, which in turn causes fluctuations in water output indicators during operation. For the problems and situations where the operating companies are unable to intervene, they can only rely on the relevant departments to issue guidance policies, strengthen the investigation and supervision of enterprises and pipeline networks in the jurisdiction, and help the operating companies avoid operational risks and hidden dangers caused by the above-mentioned uncontrollable factors.

In order to better guarantee the healthy operation of my country's urban sewage treatment plants, Cheng Hanfei suggested that detailed assessment rules should be issued to make the implementation of laws and policies clearer. Clarify the respective responsibilities and obligations of the competent authority and the sewage treatment plant, establish a "plant-web-site" integrated public platform and sewage treatment plant matter report and emergency response system to avoid possible inaccuracy and inaction to the greatest extent And let the sewage treatment plant "back the pot" situation happen.

In 2015, the Ministry of Finance and the State Administration of Taxation issued a notice on the "Products and Services Comprehensive Utilization of Resources VAT Preferential Catalogue" (Circular Caishui 78). The "Notice" stipulates that: Taxpayers with refund policies who are punished for violating taxation and environmental protection laws and regulations (except for warnings or a single fine of less than 10,000 yuan), within 36 months from the month after the penalty decision is issued, shall not enjoy the provisions of this notice The VAT is collected and refunded immediately.

The above-mentioned sewage plant operators stated that due to unclear regulations, although the environmental protection penalties for value-added tax are more than 10,000 yuan, the value-added tax will not be refunded for three years, the starting point of the minimum fines for exceeding the standard specified in the Water Pollution Prevention and Control Law is 100,000 yuan, so once the enterprise exceeds the standard, the actual direct economic loss is very huge. Among them, the large-scale sewage treatment plant is even as high as more than 10 million yuan, and some companies with weak profitability have to declare bankruptcy.

Cheng Hanfei suggested that a clearer explanation of preferential policies should be issued to reduce the difference in implementation due to human understanding; at the same time, preferential policies during the construction of sewage plant projects should be used as an encouragement during the operation period to avoid the impact of operating cost gaps The normal operation of the sewage treatment plant.

At the same time, sludge treatment and disposal methods have gradually become a key factor restricting the compliance of sewage treatment plants. Relevant departments carry out overall planning and layout of sludge disposal facilities to help companies legally and reasonably solve sludge disposal problems and avoid The hidden dangers of excessive effluent risk or decreased treatment capacity caused by the excessively high concentration of sludge in the system have also become the demands of sewage treatment plant operating companies.

Cheng Hanfei suggested that the corresponding mandatory standards should be improved, departmental coordination should be strengthened, and ground support should be provided for the scientific disposal of sludge, so as to prevent sewage treatment plants from being unable to operate normally due to the backlog of sludge.

In addition, Cheng Hanfei proposed that detailed rules for solving environmental protection inspection problems should be formulated, with a "problem-measure-standard-responsibility-acceptance-education" checklist to make the problem solving more scientific and thorough; develop sewage treatment nationwide Special inspectors for the payment of treatment fees ensure the normal operation of the sewage treatment plant, and truly implement the "who discharges the pollution who pays", forcing the sewage disposal unit to transform and upgrade and develop green.
