摘　　要：利用本地土壤为基质,分别构建美人蕉、菖蒲、麦冬、鱼腥草和空心莲子草人工湿地,研究其对城市生活污水的净化效率,并探讨了处理流量对城市生活污水中各污染物净化效率的影响。结果表明,各种人工湿地对城市生活污水的TP、TN和NH4+-N的去除效果都很好;美人蕉、菖蒲、麦冬人工湿地对COD和浊度的去除效果较好;空心莲子草人工湿地对COD的去除效率稍差一些,鱼腥草人工湿地对浊度的去除稍差一些。The local soil matrix, constructed artificial wetlands of canna indica, acorus calamus, ophiopogon japonicus, lithhocarpus polgstachrch and alternanthera philoxeroides was used to examine purifying efficiency of these wetlands on domestic sewage of city. And the effect of flow of the sewage on purification efficiency of pollutants was discussed. The results showed that all artificial wetlands had been beneficial to remove total phosphorus, total nitrogen, and ammonium from domestic sewage. Wetlands of canna indica, acorus calamus and ophiopogon japonicus could reduce more chemical oxygen demand than wetland of alternanthera philoxeroides. And they could removed more turbidities of sewages than wetlands of Lithhocarpus polgstachrch.
