摘　　要：介绍了太湖流域某城市污水处理厂采用的A(2A)O-MBR组合工艺及该工艺的主要特点。通过对污水处理厂的运行情况进行分析,研究了组合工艺对COD、NH3-N、TN和TP等各种污染物的降解特性。监测数据表明,该工艺运行稳定可靠,出水水质稳定达到城镇污水处理厂污染物排放标准(GB 18918-2002)中的一级A排放标准,COD、NH3-N、TN和TP去除率分别为91.9%、98.1%、64.5%和95.8%,并具有较强的耐冲击负荷能力。A municipal wastewater treatment plant in Taihu Area employed A（2A）O-MBR process.The thesis introduced the main features of the process.Based on the analysis of practical operation data,the effects on pollutant degradation characteristics from combination process were studied.The detect data indicated that operation and treated water quality were stable.And the effluent quality could be up to the acriteria of Class I specified in discharge standard of pollutants for municipal wastewater treatment plant（GB 18918-2002）.The results showed：the removal rates of the COD,NH3-N,TN and TP were 91.9%,98.1%,64.5% and 95.8%,respectively.Also,the whole system had strong resist impact load capability.
