摘　　要：以南方农村分散式生活和养殖混合污水为处理对象,构建由生物滤池-人工湿地-稳定塘组合生态处理系统。运行结果表明:该处理系统对NH^+_4-N、TN、TP和COD年平均去除率分别为93.8%、93.4%、90.2%和86.0%,单位面积去除负荷依次为5.12,8.31,0.45,15.92 g/(m^2·d)。其中,氮、磷的去除主要在生物滤池和人工湿地中得到去除,而COD主要由生物滤池去除。组合生态处理系统可有效处理农村分散式混合污水,出水水质稳定,可达GB 18918—2002《城镇污水处理厂污染物排放标准》一级B标准,具有良好的应用前景。The integrated ecological treatment system(IETs) including biofilters, constructed wetland, and stabilization pond was constructed to treat decentralized rural domestic sewage and livestock breeding wastewater in South China. The operation results of the system in 2014 showed that the average removal efficiencies of the system to NH+4-N、TN、TP and COD were 93.8%, 93.4%, 90.2% and 86.0% respectively, and removal loads per unit were 5.12, 8.31, 0.45, 15.92 g/(m2·d) respectively. Where, most of nitrogen and phosphorus were removed in biofilters and constructed wetlands, and most of COD was removed by biofilters. The integrated ecological treatment system can dispose the decentralized rural mixed sewage effectively with stable effluent quality which can meet the Level 1 B criteria specified in "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant"(GB 18918—2002). These findings indicated that IETs had a good application prospect.
