摘　　要：通过在室内模拟污水中培养试验,研究安徽省内9种常见植物对模拟污水的净化作用,为省内河流及湖泊氮磷污染的生物修复提供参考.结果表明,植物对模拟污水均有明显的净化作用,且随水力停留时间的延长,植物对污水中氮、磷元素的去除率逐渐增加.其中空心菜、美人蕉2种植物的净化效果较为突出且适应性良好,是较好的污水净化备选植物.Nine kinds of plants that are commonly seen in Anhui province were tested for sewage purification by indoor waste water simulation cultivation experiment, which can provide references for biomediation of ni- trogen and phosphorous in the rivers and lakes within the province.The outcomes showed obvious purification effect by those plants and the increased removal rate with the extension of hydraulic retention time.Both Ipo- moea aquatic Forsk and Canna Indica show excellent purification effects with good accommodation,which are better candidates for sewage purification plants.
