摘　　要：我国广大农村地区对生活污水处理的需求日益紧迫,急需经济、高效、适用性强的农村分散生活污水处理技术,因此采用地下渗滤系统处理农村生活污水,设计排水量为0.4m3/d,地下渗滤系统池面积为2.4m2,进水为真实农村生活污水。对系统运行500d的进出水水质进行了分析,结果表明地下渗滤系统对生活污水中的氨氮、CODcr、总氮、总磷的去除率分别为57%、68%、44%和45%。试验证明利用地下渗滤系统处理农村单户生活污水地具有广阔的应用前景。The need of rural domestic sewage treatment is increasingly urgent, especially rural decentralized domestic sewage treatment technology, which is economical, efficient and applicable. The subsurface infiltration system is applied to treat rural domestic sewage in this paper, the design discharge is 0.4 ma/d, the area of subsurface infiltration system pool is 2.4 m2. The influent is real rural domestic sewage. The influence and effluence of 500 days are analyzed, the results show that the average removal rate of sys- tem on NH＋ -N, CODor, TN, TP are 57 %, 68%, 44 %, 45% . For these reasons, the system has extensive application prospect in rural domestic sewage treatment.
