According to the relevant person in charge of the Beijing Municipal Development and Reform Commission, Beijing’s sewage treatment and resource utilization are at the national leading level, with a good foundation. During the 13th Five Year Plan period, Beijing has built and renovated 40 new reclaimed water plants, built and renovated more than 2000 kilometers of sewage collection pipelines, solved the problem of sewage collection and treatment in more than 1000 villages, and increased the city’s sewage treatment capacity to 7.5 million cubic meters / day. By the end of the 13th five year plan, the sewage treatment rate of the city has reached 95%, and the utilization rate of reclaimed water has exceeded 60%, basically realizing the harmless disposal of sludge. The annual utilization of reclaimed water reaches 1.2 billion cubic meters, becoming a stable “second water source”, providing a stable water source for the recovery of urban river and lake ecological environment.

According to the person in charge, the Committee and the Beijing Municipal Water Affairs Bureau jointly issued the development plan for sewage treatment and resource utilization during the 14th Five Year Plan period in Beijing (hereinafter referred to as the plan), implemented the water control policy of “giving priority to water conservation, spatial balance, systematic treatment and two hands”, and proposed to accelerate the formation of a new pattern of sewage treatment and resource utilization with reasonable layout, systematic coordination, safety, high efficiency, energy conservation and low carbon, and perfect mechanism.

Improve the sewage collection and treatment system

——Make up for the shortcomings of urban sewage collection facilities. We will comprehensively promote the construction of incremental sewage pipe networks, and actively carry out hidden transformation of existing sewage pipe networks. We will accelerate the completion of the treatment of mismatched and mixed drainage facilities, and implement the transformation of rainwater and sewage diversion according to local conditions.

——Improve rural sewage collection capacity. According to the principle of combining centralization and decentralization, the rural sewage treatment mode shall be reasonably selected. We will accelerate the improvement of rural sewage collection networks, focusing on villages in the urban-rural fringe, villages around water sources, folk tourism villages and densely populated villages. During the 14th Five Year Plan period, domestic sewage collection and treatment projects in more than 900 villages were completed.

——Strengthen sewage sludge treatment and disposal level. Scientifically plan and build reclaimed water plant stations, and accelerate the upgrading of urban sewage treatment plants. Vigorously promote the construction of green technology application scenarios such as reclaimed water source heat pump, biogas power generation and photovoltaic power generation, and actively promote the green and low-carbon transformation of reclaimed water plant stations. Build rural sewage treatment facilities according to local conditions. Further improve the harmless disposal level of sludge.
