摘　　要：本研究考察了以改良型厌氧/缺氧/好氧(A^2/O)工艺为工程主体的污水处理厂对市政污水的处理效果。污水处理厂出水水质均达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级B排放标准,其中SS、CODCr、NH3-N、TN和TP去除率分别达到98.2%、93.1%、99.5%、75.5%和97.3%,且各指标去除率全年波动不超过6.9%。结果表明,改良A^2/O工艺对市政污水中有机物、氮和磷的去除效果不但显著且非常稳定。The treatment efficiency of wastewater treatment plants with improved anaerobic/anoxic/aerobic （A2/O） process as the main part for municipal wastewater was investigated in this study. The results showed that the effluent quality could meet the Grade I -B discharge standard required by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB18918-2002）, and the removal efficiency of SS, CODcr, NH3-N, TN and TP were 98.2 %, 93.1%, 99.5 %, 93.1% and 99.5 %, respectively. It was also to be found that the fluctuation of removal efficiency for each indicators was no more than 6.9 %. The above research showed that the removal efficiency of organic, nitrogen and phosphorus in municipal wastewater treated by improved A2/O was not only significant but also very stable.
