Continue to promote the quality and efficiency of sewage treatment and work together to win the battle of green water protection

The Population, Resources and Environment Committee of the NPC organized a research team to go to Henan and Sichuan for field research and found that due to the unclear bottom of the pipeline network, long-term lag in construction, and prominent problems of facility shortboards and debts, there are still many problems in implementing the new development concept, building a long-term guarantee mechanism, formulating standards and scientific and technological support.

 To this end, it is recommended that:

First, improve ideological understanding and enhance action consciousness. 

Second, we need to get a full picture of the situation and make up for weaknesses. Concentrate on finding out the bottom number of urban sewage pipe networks and other facilities, master the total number of pipe networks, the distribution of blank areas, and the number of mixed wrong connections, missed connections, and old and damaged pipe networks that need to be updated and repaired, and make up all kinds of shortcomings as soon as possible. Combined with urban renewal and new urban infrastructure construction, actively promote the construction of intelligent dynamic drainage information system, and improve the efficiency of sewage collection and treatment facilities.

Third, formulate standards scientifically and innovate management mechanisms. Differentiated sewage treatment standards should be formulated to match the water functional areas, regional economic development levels, and sewage recycling destinations. We will formulate scientific guidelines on pollution control standards for combined flow control and overflow during the rainy season, and adjust the treatment and discharge standards for industrial parks and industrial sewage. Further promote the integrated operation of the plant network and river (lake), pilot the integration reform of "supply and discharge and clean governance", and achieve the integration of project investment, construction, management and transportation, and intensive and large-scale facility operation and maintenance.

Fourth, improve the pricing system and introduce market mechanisms. Implement the dynamic adjustment mechanism for sewage treatment fees, and bring the operation and maintenance costs of sewage pipe networks into the coverage of sewage treatment fees. Guide the adjustment of the business direction of central and state-owned enterprises in some competitive industries, and shift to urban sewage treatment and other public facilities industries. Innovate the business model, introduce the market mechanism through the capitalization of assets, and attract social capital to participate in the construction.

E Jingping, member of the 19th Central Committee of the Communist Party of China, Deputy director of the Committee of Population, Resources and Environment of the CPPCC National Committee, former Minister of Water Resources: Comprehensively improve the standard system to clarify the target responsibility

For the improvement of the quality and efficiency of urban sewage treatment, it should be closely focused on: sewage collection, reasonable determination of sewage treatment capacity, to ensure the benign operation of sewage treatment plants and recycled water plants, the three main points, seize the key point, and focus on the work.

At present, all localities are actively carrying out relevant work in these three aspects, and there are achievements and improvements. But overall there are still unsatisfactory, the main problems are: sewage collection rate is not high, rain and pollution mixed wrong connection, pipeline leakage and so on are common; The problem of insufficient and excessive sewage treatment capacity exists at the same time. The proportion of problems that sewage plants and recycled water plants can not run well is too high. To this end, it is recommended that:

First, comprehensively improve norms, standards and systems. First of all, it is said that the three aspects of clean sewage collection, treatment and benign operation are done to what is done. To do this well is both necessary and urgent, problem-oriented and fundamental.

2. Define specific goals and tasks. 

Third, specific responsibility. The key of urban sewage treatment is to strengthen the responsibility system. It is suggested that from the central government to the local government, from the government to the department, from the public institution to the enterprise, to comprehensively clarify the responsibility and clarify the main body of responsibility. At the same time, the establishment of relevant operational mechanisms for the landing of responsibilities.

Wang Fuming, member of the National Committee of the Chinese People's Political Consultative Conference, Dean of the School of Civil Engineering of Sun Yat-sen University, Academician of the Chinese Academy of Engineering: Accelerate the improvement of scientific and technological innovation and talent training capacity of underground pipe network

The scale of underground pipelines in Chinese cities is huge and the disrepair is widespread. In recent years, scientific and technological innovation in the construction and maintenance of underground pipelines has gradually received extensive attention from the state and local governments, and technical problems such as full-load pipeline detection, rapid desilting of small-caliber pipelines, loose soil outside the pipelines and diagnosis and treatment of hidden diseases of cavitation need to be solved, and the problems of insufficient scientific and technological innovation ability and lack of senior specialized talents have become increasingly prominent. To this end, it is recommended that:
