摘　　要：某汽车塑料零配件有限公司产生的前处理废水和循环废水共85 m3/d,原废水处理站存在设计缺陷且设备老化已不能使出水水质满足上海市《污水排入城镇下水道水质标准》(DB31/445—2009)。将处理工艺改造为循环废水收集池/前处理废水收集池/调节池/气浮池/水解酸化池/两级接触氧化池/二沉池后,出水水质远远优于上海市纳管排放要求,其中气浮预处理效果良好,COD去除率>55%。在调试过程中,还解决了阻碍污水站通畅运行的各种问题。85 m3/d of pretreatment wastewater and recirculation wastewater are discharged by an auto plastic parts company. Due to process design defects and serious aging of facilities, the treated water quality of the original sewage station could not meet the requirements of local Discharge Standard for Mu- nicipal Sewerage System （DB 31/445 -2009） in Shanghai. A combined treatment process of recirculation wastewater tank/pretreatment wastewater tank/regulating tank/air floatation tank/hydrolytic acidification tank/two-stage contact oxidation tank/secondary sedimentation tank was used to upgrade the original process. The treated water quality was much better than the local standard for discharging to pipes. The removal efficiency of COD is above 55% after the efficient pretreatment unit of air floatation. During the commissioning phase, various problems that obstructed the operation of the new sewage treatment station were solved.
