摘　　要：选取炉灰渣、砾石、沸石3种单一基质及组合基质,选取美人蕉、黄菖蒲、芦苇、香蒲、凤眼莲5种水生植物,通过生态盆栽实验模拟小型人工湿地,研究了不同水生植物和基质对城市生活污水中的COD、TP、TN的去除效果,其中香蒲净化污水效果最佳,COD去除率为86.3%,TP去除率为82.4%、TN去除率为82.3%。而基质中的炉灰渣净化效果最佳,其COD去除率为71.0%,TP去除率为75.5%,TN去除率为69.5%。In this paper,three single substrates and combined substrates of furnace ash,gravel and zeolite,and five aquatic plants of Canna,gladiolus,reed,cattail and water hyacinth were selected.Through ecological pot experiment to simulate small-scale constructed wetland,the removal effects of different aquatic plants and substrates on COD,TP and TN in urban domestic sewage were studied.Among them,cattail has the best effect on purifying sewage,The removal rates of COD,TP and TN were 86.3%,82.4%and 82.3%,respectively.The purification effect of furnace ash in the matrix is the best,with COD removal rate of 71.0%,TP removal rate of 75.5%and TN removal rate of 69.5%.
