摘　　要：杭州某大型地下式生活污水处理厂设计规模为15.00万m^(3)/d,采用了“曝气沉砂池-AAO-MBR”工艺,实际工程结果表明:“曝气沉砂池-AAO-MBR”工艺能够稳定实现COD_(Cr)、TN、氨氮、TP、SS的去除,出水优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A的标准要求,且MBR运行稳定,膜污染不显著;工程总投资为9.8亿元,运行总成本约为0.9000元/m^(3),为大型地下式污水处理厂设计提供了实际经验。The design scale of a large underground wastewater treatment plant(WWTP)in Hangzhou is 15×10^(4) m^(3)/d,which adopted"aerated grit chamber-AAO-MBR"process.Actual engineering results show that,the process of"aerated grit chamber-AAO-MBR"can remove the COD_(Cr),TN,ammonia nitrogen,TP and SS stably.Effluent quality is better than the first class A criteria of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002).Operating of MBR is stabling and the fouling of membrane is unsignificant.The total investment of the project is 980 million yuan and the total operating cost is 0.9000 yuan/m^(3),which provides practical experience for the large-scale underground WWTP.
