摘　　要：通过构建小型水生生态系统,研究了旱伞草、美人蕉、伊乐藻、金鱼藻4种水生植物对太湖流域污水处理厂尾水中氮、磷等指标去除效能的差异。结果表明,4种水生植物对污水中的氮、磷等均有明显的去除效果,其中,挺水植物旱伞草和沉水植物金鱼藻的综合净化效能较强,综合净化能力从强到弱依次为金鱼藻、旱伞草、伊乐藻、美人蕉。Based on building the small aquatic ecosystem, the removal efficiency of nitrogen and phosphorus in sewage treatment plant tail water of Taihu Lake Basin by Cyperus alternifolius, Canna indica, Elodea Canadensis Michx.and Ceratophyllum demersum L.was studied.The results showed that these four plants had good removal efficiency for nitrogen and phosphorus in wastewater.The comprehensive purification ability of emerged plants Cyperus alternifolius and submerged plants Ceratophyllum demersum L.was higher than that of the others.The order of comprehensive purification ability from strong to weak was Ceratophyllum demersum L., Cyperus alternifolius, Elodea Canadensis Michx., Canna indica.
