植物—土壤渗滤法对农村生活污水降解研究

The Degrade Effect of Plant-soil Infiltration System on Rural Domestic Sewage

采用植物—土壤渗滤法对农村生活污水进行处理,结果表明,体系对BOD5、COD、TN、NH4+-N、TP的平均去除率分别为86.04%、75.74%、85.54%、91.26%、89.27%,出水达到国家一级排放标准,通过试验证明了该工艺在农村生活污水处理中具有广阔的应用前景。

The plant-soil infiltration system was applied to treating rural domestic sewage. The results showed that the average removal rate of system on BOD5, COD, TN, NH4^＊-N and TP were 86.04%, 75.74%, 85.54%, 91.26%, 89.27% respectively and effluent water reached to national primary discharge standard. For these reasons, this system has extensive application prospect in rural domestic sewage treatment.
