摘　　要：选择芦苇(Dried reeds)、美人蕉(Canna)、香蒲(Bulrush)三种常见水生植物作为人工湿地植物,研究了它们对农村生活污水中主要污染物的去除能力。试验结果表明:三种水生植物均生长良好;当污水停留时间(HRT)为7d时,对污水中COD、TP、TN、NH3-N与浊度的去除率,芦苇分别为65.3%、84.5%、55.3%、77.2%和83.5%,美人蕉分别为81.3%、77.3%、83.2%、90.3%和83.7%,香蒲分别为74.3%、68.3%、74.9%、88.9%和89.2%,出水水质基本达到城镇污水处理厂污染物排放标准(GB18918-2002)的要求。Three kinds of common aquatic plants, Dried reeds, Canna and Bulrush as the constructed wetland plants, have been chosen. Their purification ability of the main pollutants in rural domestic sewage has been studied. The results show that three kinds of plants all grow well. When the water retention time （HRT） is seven days, the removal rates of COD, TP, TN, NH3-Nand turbidity in Dried reeds wetland are 65.3%, 84. 5%, 55.3%, 77.2% and 83.5%, respectively. In Canna wetland, the removal rates of COD, TP, TN, NH3-N and turbidity are 81.3%, 77. 3%, 83.2%, 90. 3% and 83.7%, respectively. And those in Bulrush wetland are 74. 3%, 68. 3%, 74. 9%, 88. 9% and 89. 2%, respectively. The indicators of the final effluent basically reach the requirements of the discharge standard of pollutants for municipal wastewater treatment plants （GB 18918-2002）.
