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

First, the time to improve the quality and efficiency of urban sewage treatment is ripe, and it needs to be paid great attention to and tackled systematically. First, we need to raise awareness and increase input. It is necessary to stand on the strategic height of promoting the construction of ecological civilization, promoting the work of carbon peak carbon neutrality, and promoting the transformation of green and low-carbon development mode, with greater determination and investment, speed up the shortcomings of urban sewage treatment, and fundamentally eliminate the basic obstacles restricting China's economic and social development, especially urban development. The current opportunity is ripe, and we should attach great importance to and increase investment. Second, we need to make up for weaknesses systematically and with high standards. It is not only necessary to comprehensively consider the problem of sewage collection, treatment and recycling, but also to consider all pipelines and other facilities entering the underground, unified planning and package solution; It is necessary to proceed from the long-term interests of the country and the people, with a high starting point, high standards, and advanced planning and construction. Third, we must strictly implement the construction timing and consolidate local responsibilities. Whether it is real estate development or industrial projects, it is necessary to do the sewage treatment plant network first, and urge the government to move forward with sewage treatment facilities. Not only should the "three-year action" achieve practical results, but also promote this work to be further advanced during the "14th Five-Year Plan" period.

Second, the focus of promoting the quality and efficiency of urban sewage treatment should be clear, and it is necessary to pay equal attention to construction and maintenance, and take into account the utilization of resources. First, we will strengthen surveys and surveys. Figure out the urban drainage pipe network connection, drainage households and outlet distribution, drainage volume and water quality characteristics, industrial enterprises drainage destination and water quality conditions, and establish a municipal drainage pipe network geographic information system. Second, we will strengthen the construction, renovation and maintenance of facilities. Strengthen the construction of sewage and sludge treatment plants, reclaimed water utilization plants and other facilities; Strengthen the "blank area" of drainage pipe network, especially the construction of pipe network in urban villages, old and old urban areas, and urban and rural areas; Strengthen the maintenance and renovation of the supporting pipe network defects of each sewage treatment facility; Carry out periodic inspection and maintenance of pipe network. Third, we will control the source of industrial sewage. The construction of industrial parks should ensure the single and orderly discharge of relevant pollutants. Fourth, promote the resource utilization of sewage sludge. Vigorously promote the resource utilization of urban domestic sewage treatment. We will introduce incentive policies and targeted subsidies for enterprises using reclaimed water. Explore the resource utilization of sludge, and introduce the utilization standards of sludge terminal products.

Third, to establish a long-term mechanism to promote the quality and efficiency of urban sewage treatment, it is necessary to improve the policy system and crack the market problems. First, we will improve the legal system. Strengthen the implementation of the Law on Water Pollution Prevention and Control and the Regulations on Urban Drainage and Sewage Treatment, and clarify the penalties for failing to plan and build centralized industrial sewage treatment facilities in industrial agglomeration areas and failing to prioritize the construction of drainage and sewage treatment facilities in the development and construction of new urban areas. We will innovate the drainage management mechanism, vigorously implement the management of "factory-network-river (lake) integration", and pilot the integration reform of "supply and discharge and clean control". Change the separate management model, and promote the transformation of drainage management to fine. Second, establish normative and scientific standards. Formulate differentiated discharge standards that match the water functional areas, the level of regional economic development, and the destination of sewage recycling. Clear the overflow pollution control standard of combined flow control in rainy season. As soon as possible to adjust the industrial parks and industrial sewage treatment and discharge standards. Third, explore market-based models. We will carry out trials of cost accounting for the whole process of sewage collection and treatment in major cities, and expand the trials and gradually promote them in large and medium-sized cities where conditions permit. We will give full play to the backbone role of state-owned enterprises and introduce market mechanisms. Revitalize existing pipeline network assets. We will encourage the packaging of projects with stable returns such as water supply and sewage treatment with input projects such as pipeline network construction and operation, and attract the participation of social capital. Fourth, we will strengthen scientific and technological support and personnel training. Strengthen the application of new technologies, and realize the dynamic update of drainage system, intelligent operation, diagnosis and evaluation, and departmental collaboration. Strengthen research and development of new technologies, new materials and new equipment for underground pipe networks. Fully tap the energy and resources contained in sewage and sludge. We will strengthen the training of professional and technical personnel at all levels in the field of underground pipe network safety protection. Construction of underground pipeline safety protection field training base.
