利用模拟自然湿地的静态水培试验法，研究了梭鱼草、鸢尾、芦苇、菖蒲、香根草、水葱、茭白、旱伞草、再力花、大皇冠等10种人工湿地植物对生活污水的净化效果。结果表明：（1）10种植物对污染物的年平均去除率在40％～70％，对4种污染物的去除能力由大到小表现为TP、NH4＋-N、TN、COD。 TP去除率最高的为再力花，达78％，NH4＋-N去除率最高的为梭鱼草，达74％，TN去除率最高的为鸢尾，达70％，COD去除率最高的为梭鱼草，达65％。（2）对TP的去除率由大到小依次表现为秋季、夏季、春季、冬季，对NH4＋-N、TN和COD的去除率由大到小依次表现为夏季、春季、秋季、冬季。

The decontaminating effects of ten wetland plant species including Pontederia cordata,Iris ger-manica,Phragmitas communis, Acorus calamus Linn, Vetiveria zizanoides, Scirpus validus, Zizania latifolia, Cyperus alternifolius,Thalia dealbata,Echinodorus amazonicus were studied by using simulated solution culture experiment .The results showed:( 1 ) the annual average rates of pollutant removal of the ten plants were be-tween 40%and 70%,and the removal ability for 4 pollutants showed the order of TP ﹥NH4+-N﹥TN﹥COD.The highest TP removal rate was that of Thalia dealbata being 78%,the highest NH4+-N removal rate was that of Pontederia cordata being 74%,the highest TN removal rate was that of Iris germanica being 70%, the highest COD removal rate was that of Pontederia cordata being 65%;( 2) the average seasonal TP removal rates of the ten species showed the order of autum ﹥ summer ﹥ spring﹥ winter,however the NH4+-N,TN and COD removal rates showed the order of summer ﹥spring﹥autum﹥winter .
