Guiding opinions on promoting the resource utilization of sewage

(10) Implementation of agricultural and rural sewage use promotion and treatment projects. Gradually build and improve agricultural sewage collection, treatment and reuse facilities, and realize nearby irrigation reuse after treatment standards. Focusing on large-scale livestock and poultry farms, we will explore and improve the operation mechanism, carry out the resource utilization of livestock and poultry waste, and promote the circular development of breeding and breeding combined with agriculture and animal husbandry, so that the comprehensive utilization rate of livestock and poultry waste will reach more than 80% by 2025. In the Yangtze River Economic Belt, the Beijing-Tianjin-Hebei region, the Pearl River Delta and other areas where conditions permit, the resource utilization of fishery aquaculture tail water should be carried out, focusing on pond aquaculture, and the treatment of aquaculture tail water should be carried out to achieve recycling and discharge up to standards.

(11) Implementing pilot projects for technological innovation in near-zero sewage discharge. Select representative national high-tech industrial development zones (hereinafter referred to as National high-tech Zones) to carry out comprehensive technology integration and demonstration, develop and integrate low-cost, high-performance industrial wastewater treatment technologies and equipment, and create demonstration models of sewage resource technology, engineering and services, management, and policies. In the Yangtze River Delta region, selected electronic information, textile printing and dyeing, chemical materials and other national high-tech zones to take the lead in demonstration, and built a number of national high-tech zones industrial wastewater near zero emission scientific and technological innovation pilot projects by 2025.

(12) Comprehensively carrying out trials and demonstrations for the utilization of sewage resources. Focusing on key and difficult points, pilot demonstrations of recycled water utilization, sludge resource utilization, groundwater recharge, nitrogen and phosphorus extraction and energy resource recovery will be carried out in light of local conditions. Demonstration cities for wastewater resource utilization will be built in cities at prefecture level and above in the Yellow River Basin, and supporting infrastructure will be planned to realize large-scale utilization of recycled water. Pilot projects of reclaimed water utilization and allocation were carried out in typical areas. Through the pilot demonstration, the successful experience is summarized, and the model of sewage resource utilization can be replicated and promoted. Innovate the service model of sewage resource utilization, and encourage third-party service enterprises to provide overall solutions. We will build benchmarking water plants for resources and energy, and carry out trials to recover energy substances from sewage.

Fourth, improve the system and mechanism for the utilization of sewage resources

13. Improving regulations and standards. We will promote the formulation of regulations on water conservation, encourage the utilization of sewage resources, and achieve water saving, open source and emission reduction. We will accelerate the improvement of relevant policies and standards, and incorporate recycled water into urban water supply systems. Promote the formulation and revision of local water pollutant discharge standards, and put forward differentiated pollutant discharge requirements and control measures. We will promptly formulate technical specifications and control requirements for the use of recycled water for ecological water replenishment, and timely revise the series of standards for the classification and quality of sewage resources for other uses. To formulate and revise equipment, engineering and operation standards related to sewage resource utilization.

14. Building a policy system. We will formulate implementation plans for pilot projects for regional recycled water utilization, pilot projects for the utilization and allocation of recycled water in typical areas, pilot projects for industrial wastewater recycling, harmless resource utilization of sludge, and pilot projects for scientific and technological innovation of near-zero discharge of industrial wastewater in national high-tech zones, and refine work priorities and main tasks to form a "1+N" policy system for the utilization of sewage resources. To study and formulate the 14th Five-Year Plan for the utilization of sewage resources and other related plans. To study the statistical methods and systems of sewage resource utilization and establish a scientific and unified statistical system. We will improve the relevant provisions on the assessment of unconventional water use indicators in the total water use control indicators, increase the weight of renewable water and other unconventional water use, and implement classified assessment. We will improve the water intake permit management system, and formulate and implement guidance documents on the supervision and management of sewage discharge outlets into rivers (seas).
