摘　　要：随着国家对水环境的不断重视,排水标准也在不断提高。太湖流域水网密集、水环境敏感性强,对出水排入太湖的污水处理厂提出了更高的要求。某污水处理厂采用“倒置A^(2)/O-MBR-磁混凝”组合工艺处理污水,出水能满足准Ⅳ类地表水排放标准。对工艺特点、主要构筑物工艺参数进行了分析,通过对4月中下旬每一天的COD、TP、TN、NH_(3)-N监测数据进行分析,评价污水处理厂运行效果。运行结果表明,污水经过处理后,COD、TP、TN、NH_(3)-N平均去除率分别达到83%、90%、81%、98%,出水COD、TP、TN、NH_(3)-N各项指标的平均值分别为25.00、0.28、5.33、0.33 mg/L,5月平均处理水经营成本为0.84元/m^(3)。With the continuous attention of the country to water environment,the drainage standard is also constantly improving.The water network of Taihu Lake basin is dense and the water environment sensitivity is strong,which puts forward higher requirements for wastewater treatment plants discharging effluent into Taihu Lake.A certain sewage treatment plant adopts the combination process of"inverted A^(2)/O-MBR-magnetic coagulation"to treat sewage,and the effluent can meet the Class IV surface water discharge standard.The process characteristics and process parameters of the main structures were analyzed,and the operation effect of the wastewater treatment plant was evaluated by analyzing the monitoring data of COD,TP,TN and NH_(3)-N every day in mid-to-late April.The operation results showed that after wastewater treatment,the average removal rates of COD,TP,TN and NH_(3)-N reach 83%,90%,81% and 98%,respectively,and the average indexes of effluent COD,TP,TN and NH_(3)-N were as follows:25.00,0.28,5.33,0.33 mg/L,and the average operating cost of treated water in May was 0.84 yuan/m^(3) of wastewater.
