摘　　要：北京碧水下沉式再生水厂作为北京城市副中心水环境治理的核心项目,采取PPP模式,在原地上厂厂址内新建一座全封闭下沉式再生水厂,占地面积仅为原厂的1/3。在改造过程中,原厂仍可实现正常运行并保证出水达标排放。新建碧水下沉式再生水厂处理规模由原10×10~4m^3/d提升至18×10~4m^3/d,采用多级AO工艺、双层矩形平流沉淀池、高效沉淀+超滤深度处理、污泥低温风冷干化及高效生物除臭等先进处理技术,出水水质由《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准提升至北京市地方标准《城镇污水处理厂水污染物排放标准》(DB 11/890—2012)的B级标准。同时,该厂结合地上景观与市政设施的建设,打造集水质净化、生态景观、休闲运动和科普教育于一体的城市生态综合体。As the core project of water environment improvement in Beijing sub-civic center, Bishui underground wastewater treatment plant was built through public-private partnership model, which located in the original plant and covered 1/3 area of original plant. During the upgrading construction period, the performance of the original wastewater treatment plant was kept stable and the effluent quality could meet the emission standard requirements. The treatment capacity of the new underground plant was improved from 10×10^4m^3/d to 18×10^4m^3/d. The combination treatment processes were adopted in the new underground plant, including multi level A/O process, double rectangular-horizontal flow sedimenta- tion tank, high-efficiency settling tank, UF advanced treatment unit, low temperature sludge drying and biological deodorization technology. The requirement of effluent quality standard was upgraded from first grade B standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002 ） to B standard of Beijing Discharge Standard of Water Pollutants for Municipal Wastewater Treatment Plant（DB 11/890- 2012 ）. Urban ecological complex was constructed by the Bishui under- ground wastewater treatment plant together with the ground landscape and municipal facilities. In the urban ecological complex, the wastewater treatment, ecological landscape, recreational activity and popular science bases were built into an integral circle.
