Design of Renovation of a Small Sewage Treatment Station in Beijing

北京市某小型污水站采用A2O+MBR工艺,处理水量为1000t/d,设计出水水质达到北京市《水污染物综合排放标准》(DB11/307-2013)中村庄生活污水处理站A标准。实际运行中,污水站的出水总氮和总磷不合格。通过对原有工艺环节出现的实际问题进行分析,针对出现的问题,通过对厌氧池、好氧池、排水池改造后,污水厂的出水稳定达标。

A small sewage station in Beijing adopts the A2O+MBR process with a water treatment capacity of 1,000 tons/day.The designed effluent quality meets the village sewage treatment station A in the "Comprehensive Discharge Standard of Water Pollutants"(DB11/307-2013)standard.In actual operation,the total nitrogen and total phosphorus in the effluent of the sewage station are unqualified.Through the analysis of the actual problems in the original process,the effluent of the sewage plant has reached the standard steadily after the transformation of the anaerobic tank,aerobic tank and drainage tank.
