摘　　要：昌平再生水厂二期提标及改扩建工程设计规模为3×10~4m^3/d,利用原厂区预留地进行建设,出水品质要求高,需达到北京市地方标准《城镇污水处理厂水污染物排放标准》(DB 11/890—2012)中的B标准,主工艺采用高效脱氮的多段进水A^2O工艺+深度处理工艺。主要介绍了该工程的工艺选择、工艺流程、主要设计参数、设计特点及实际运行情况。运行结果表明,该工程技术选用适宜,出水各项指标均达到设计要求。reclaimed water of the upgrading The design capacity of phase 11 project for upgrading and reconstruction of Changping plant was 3×104 m3/d. The project was built on the previous reserve area. treatment process had to meet level B of Beijing local standard Discharge Water Pollutants for Municipal Wasterwater Treatment Plants （ DB 11/890 - 2012 ）. Step The effluent Standard of feeding A2O process for effective nitrogen removal was used in the main process followed by advanced treatment unit. The project was described in following aspects：procedure treatment process selection, treatment flow path, main design parameters, design characteristics and operation conditions. The results indicated that the effluent quality could meet the requirements of design purpose with the suitable treatment process.
