摘　　要：苏南水网地区地处我国经济发达地区之一的长三角经济带,随着工农业的高速发展,村镇水污染问题日趋严重,水环境日益恶化。太湖支流-永安河前桥表面流人工湿地示范工程将村镇污水的处理与河道生态修复结合起来,利用现场地形条件,将河道改造成生活污水处理点,采用"生物栅湿地净化沟+接触氧化池+表面流人工湿地+生态护岸"组合工艺模式,对村镇污水进行处理,出水主要污染物CODCr、TN、TP、NH3-N等均低于《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级B排放要求,运行费用约为0.119元/m3。The south of Jiangsu Province is located in the Yangtze River Delta,which is one of the most developed areas in China.With the development of industry,agriculture and urbanization,the problem of w combines sewage treatment in rural areas with the river ecological restoration project.By using the combined process of ＂biological paling purifying ditch/ biological aerated filter/ surface wetland technology/ ecological embankment＂ to treat swage,the concentration of CODCr,TN,TP and NH3-N in the effluent,all can meet the GB18918-2002 1B discharge standard.The operational fee is only 0.119 yuan per ton of wastewater.
