MBR-O3工艺用于高排放标准污水处理厂的设计案例

MBR-O3process for the design of high discharge standards wastewater treatment plant

结合北京西北地区某污水处理厂工程的实施,探讨了在应对乡镇污水处理厂水质、水量波动大、出水水质要求高时工艺路线的选择及池形、参数的选取和运用。通过一年多的实际运行,出水水质稳定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 11890-2012)A标准要求。

Combining with the implementation of a wastewater treatment plant in Beijing northwest district,the selection and application of process route,pool shape and parameters are discussed when dealing with the water quality,fluctuation of water quantity and class III to be requirement of effluent quality in township sewage treatment plants.Through more than one year’s actual operation,the published water quality has reached the requirements of Beijing local standard Water pollutant discharge standard for urban sewage treatment plant(DB 11890-2012)class A.
