摘　　要：采用厌氧/湿地型生物滤池新工艺处理生活污水,在控制流量、温度不变的条件下,就系统的水力停留时间对COD、NH3-N、SS去除率的影响进行了研究,从而确定出试验的最佳水力停留时间为19 h,并在此基础上考察了系统对COD、TP、TN、NH3-N的去除效果。结果表明:生活污水经厌氧/湿地型生物滤池新工艺处理后,出水的各项常规指标均基本满足《污水综合排放标准》的二级标准,其对COD、SS、TP、TN、NH3-N的去除率分别为80%、90%、50%、15%、68%。The anaerobic/wetland biofiher process was used to treat domestic sewage. Under the conditions of controlling flowrate and constant temperature, the influence of HRT on the removal rates of COD, NH3 -N and SS was studied, thus determining the optimal HRT of 19 h. Based on this, the removal efficiencies of COD, TP, TN and NH3 - N were investigated. The results indicate that after the treatment of domestic sewage by anaerobic/wetland biofiher process, the effluent quality satisfies the second class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 - 1996）. The remoral rates of COD, SS, TP, TN and NH3 -N are 80%, 90%, 50%, 15% and 68% respectively
