摘 要:分散式无动力生活污水处理系统是我国农村生活污水处理的一个重要的组成部分,笔者在四川省乐至县选取了两种不同的无动力生活污水处理设施,对其处理效果进行了检测,检测数据表明:1)无动力生活污水净化装置对COD和SS去除明显,平均去除率可达到60%以上,出水COD多在100 mg·L^(-1)以下,SS在40 mg·L^(-1)以下;2)单独的生活污水净化池对于氨氮和磷的去除率都在10%以下,有时出水氨氮和磷会略高于进水;3)生活污水净化池+人工湿地的处理系统对于氨氮和磷的去除率较单独的生活污水净化池略有提高,5~6月份的去除率高于1~2月份去除率。Decentralized non-powered domestic sewage treatment plant plays an important role in sewage treatment in rural area of China. In this paper,two different non-powered sewage treatment systems in Lezhi County of Sichuan province were chosen and their treatment effects were detected. The results showed: 1) non-powered sewage treatment system( biogas digester) had a high removal rate for COD,SS,the average removal rate was above 60%,the effluent COD was below 100 mg·L^(-1),while SS was below 40 mg·L^(-1); 2) for the system with only biogas digester,the removal rate of NH_4^+-N and TP were all below 10%,sometimes the NH_4^+-N and TP concentrations in effluents were even higher than that in influent.3) for the system with biogas digester plus constructed wetland, the removal rate of NH_4^+-N and TP were relatively higher.The average removal rates were higher in May and June than that in January and February.
