摘　　要：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 germanica,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 between 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.
