Urban domestic sewage treatment facilities to make up the weak points of the implementation plan

Q: What are the main contents of the Implementation Plan?

A: In the drafting process of the Implementation Plan, we organized investigations and studies, listened to the opinions and suggestions of government departments, industry enterprises, experts and scholars, and proposed four key tasks for the main weaknesses of urban domestic sewage treatment facilities:

We will strengthen capacity building for sewage treatment. First, overall consideration of the capacity and distribution of urban population, and scientific determination of the layout and scale of urban sewage treatment plants. The second is to speed up the construction of sewage treatment plants and fill the gap in treatment capacity. The third is to highlight the key points, and put forward higher requirements for sewage treatment capacity and facility discharge standards in key regions such as the Beijing-Tianjin-Hebei region, the Yangtze River Economic Belt, and the Yellow River basin. The fourth is to choose water shortage areas and water environment sensitive areas, and actively promote the utilization of sewage resources. Fifth, actively promote the construction of sewage treatment facilities in incorporated towns.

Supplementing the short board of the collection pipe network, this work as the top priority of supplementing the short board, including seven contents. First, it is emphasized that the new centralized sewage treatment facilities must be rationally planned and constructed to serve the sewage collection network in the area. In addition to arid areas, the new pipe network should strictly divide rain and pollution. The second is to speed up the elimination of urban villages, old and old urban areas, urban-rural interface network blank areas, and speed up the replenishment of "capillaries". The third is to improve the efficiency of centralized sewage collection by means of cleaning and diverting, updating and repairing the pipe network, mixing and misconnecting. Fourth, for the existing urban sewage treatment plants with influent BOD concentrations below 100mg/L, it is required to carry out systematic remediation of "one plant and one policy" around the service area. Fifth, in the Yangtze River basin and cities to the south, we will promote the transformation of the combined rain and pollution pipe network to reduce the frequency of overflow pollution. Sixth, actively promote the construction of sewage collection pipe networks in towns. Seventh, improve the quality of pipe network construction, encourage the priority use of ductile iron and other pipes, and implement cast-in-place concrete or finished product inspection Wells.

To promote the harmless treatment and disposal of sludge as a resource is the difficulty of filling the weak points, including five contents. First, on the basis of reduction treatment, the appropriate disposal technology route is selected according to local conditions to avoid a one-size-fits-all approach. The second is to comprehensively promote the construction of sludge treatment and disposal facilities, and the construction of sludge treatment facilities should be included in the planning. The third is to limit the landfill of sludge that has not reached the standard of dewatering treatment, and reduce the scale of sludge landfill in key areas. The fourth is to encourage the use of "biomass utilization + incineration" disposal mode, and use incineration ash as building materials. The fifth is to promote the harmless and reduced treated sludge for land use.

Promoting the construction of information systems. It includes carrying out the investigation of domestic sewage collection pipe network, establishing pipe network geographic information system in an orderly manner according to law, and encouraging exploration of the construction of intelligent management platform, etc., to provide auxiliary decision-making for the operation and maintenance management of sewage treatment facilities and pollution prevention and control supervision.

Q: What are the main sources of funding for the weak and weak items of cities and towns?

A: We will give full play to the "two hands" of the government and the market, rationally design ways to guarantee funds, and expand the channels for financial investment and mobilize the enthusiasm of financial and social capital investment.

First, we will increase financial support. We will make clear the main responsibilities of local governments, adhere to the principle that "projects follow the plan" and "funding elements follow the project", design a diversified mechanism for ensuring the investment of financial funds, ensure that the source of project funds is reliable and the scale is sufficient, and strictly prevent "half-completed projects" and local government debt risks. Relevant departments continue to support the construction of qualified urban domestic sewage treatment facilities through various channels such as funds from the central budget, and promote the construction and implementation of projects.

Second, we will attract investment from financial institutions and private capital. Give full play to the decisive role of the market in resource allocation, and promote the PPP model in a standardized and orderly manner. Guide social capital to actively participate in construction and operation by providing medium - and long-term credit support, issuing corporate bonds and other fund-raising channels. Give play to the specialization and scale advantages of central enterprises and play a leading role. We will actively promote the trial of real estate investment trust funds, and explore financing guarantees such as project income rights and franchise rights.
