摘要
分别构建无植物、种植伞草、种植黄菖蒲以及伞草和黄菖蒲组合种植的4种人工湿地系统,通过对污水的脱氮除磷效果的测定和分析比较了成都地区不同人工湿地的污水净化效果。结果表明试验期间组合植物人工湿地对NH4+-N、TN、TP去除率均约为50%左右,黄菖蒲人工湿地对NH4+-N、TN、TP去除率均约为42%左右,伞草人工湿地对NH4+-N、TN、TP去除率均约为35%左右,无植物人工湿地对NH4+-N、TN、TP去除率均约为30%左右。
Four kinds of artificial wetland systems are established, which are planted with no plants, Cyperus alternifolius, Iris pseudacorus L, and combination plants of Cyperus alternifolius and Iris pseudacorus L. By determining and analyzing the effects of nitrogen and phosphorus removal of sewage on different constructed wetlands, compare sewage purification effects of different con- structed wetland in Chengdu region. The results show that during the experiment, the average removal efficiencies of NH＋ --N, TN and TP are almost the same in the same constructed wetland, which is about 50% for combination plant constructed wetland, about 42G for Iris pseudacorus L constructed wetland, about 35G for Cyperus alternifolius constructed wetland and about 30. 08% for non -plant constructed wetland.
