摘　　要：改良A^2O工艺为当前应用较多的污水脱氮除磷工艺。本文基于工程应用实例主对某改良A^2O工艺运行效果进行分析,结果表明该工艺对COD、氨氮具有较好的处理效果,出水平均值已经达到《城镇污水处理厂污染物排放标准》GB18918-2002一级A标准;但处理低C/N生活污水时,TN去除效果则不够理想,总氮平均去除率仅为40.9%。The modified A2O process is a popular process for waste water treatment.In this paper,the efficiency of A2O process was studied based on the running condition of a real wastewater treatment plant.The results showed that COD,NH3-N,and TP were removed well by A2O.The effluent concentrations of those contaminants can meet the requirements of A level of "Discharge standard of pollutants for municipal wastewater treatment plant".However,this process is inefficient on TN reduction;the TN was removed just at 40.9%.
