摘　　要：采用塔式蚯蚓生态滤池处理系统对集中型农村生活污水进行处理,并在江苏宜兴建设了16个示范工程。2007年的运行数据表明,该系统基建及运行费用低、处理效果好,对COD、氨氮、总氮和总磷的平均去除率分别为86.7%、91.3%、72.4%、96.2%。处理规模为10 m3/d的滤池系统建设成本(不含管网建设费)为1 656.1元/m3,总运行成本为0.671元/m3。The tower earthworm ecofiher system was used to treat centralized rural domestic sewage, and sixteen demonstration projects were constructed in Yixing, Jiangsu Province. The operating data from 2007 show that the system has good treatment effect, low construction and operating costs. The average removal rates of COD, NH4^＋ - N, TN and TP are 86.7% , 91.3% , 72.4% and 96.2% respectively. The construction cost of 10m^3/d system （non including construction cost of pipe network） is 1 656.1 yuan/m^3, and the operating cost is 0.671 yuan/m^3.
