摘　　要：用下行流人工湿地处理生活污水,分析了系统对TP,TN的处理效果,并将有无植物2种系统对污染物的去除效果进行对比。研究结果表明:下行流人工湿地对N,P都有很高的去除率;进水中TN,TP的浓度变化对出水中N,P含量影响不大,系统对N,P有一定的抗冲击能力;植物在污染物去除过程中起了一定的作用。Down-flow constructed wetland is used to treat Sewage,and the removal effect of TN and TP is made a contrastive analysis by the system with or without plant, the system has very high removal rates of TN and TP, and concentrations of TN and TP in inflow have a little influence them in outflow because of resistance to shock. Plants have some effect on the treatment process.
