| 摘 要： | 文章通过小试装置研究了表面流人工湿地对人工模拟生活污水的处理效果及相关运行参数。实验结果表明,表面流人工湿地系统对污水中的COD,TN,TP均有较好的综合净化能力,对各种污染物指标的去除率可分别达到COD 75%,TN 75%,TP 73%,其中COD和TN达到一级排放标准分别需3 d和4 d的表观停留时间,TP要达到二级排放标准则需6 d的表观停留时间。而且,湿地植物对TN和TP的去除有比较明显的促进作用。

| Abstract: | Simulated sewage was treated by laboratory artificial wetland with surface flowing water,and the performance and related operation parameters were investigated.The result showed that the removal of COD,TN,and TP reached 75%,75%,and 73% respectively.And the COD and TN could reach discharge standard Class 1 under 3 d and 4 d of apparent retention time respectively,but 6 d of apparent retention time was needed for TP reaching discharge standard Class 2.In addtion,the wetland plants could obviously improve the ... |
