摘要: 在同等条件下开展了3种植物人工浮岛对生活污水水质处理比较研究，并对它们动态净化处理结果进行比较。结果表明，水体交换时间为7 d时，灯心草、菖蒲、美人蕉3种人工浮岛对总氮的平均去除率分别为48.4%、53.7%和59.3%；对总磷的平均去除率分别为59.3%、65%和69.3%；对COD的平均去除率分别为41.5%、40.5%和40.9%。显然美人蕉对总氮和总磷的去除效果最好, 实验证明了美人蕉人工浮岛在对于生活污水处理中有广阔的应用前景。Abstract: Comparison research of three plants plants artificial floating island types to treat sewage and the dynamic purification results was carried out. Result shows that the average removal rates of total nitrogen (TN)by Juncus effusus， Acorus calamu,Canna indica,were 48.4%,53.7% and 59.3%, respectively; the average removal rates of total phosphorus (TP)were 59.3%,65% and 69.3%, respectively;and the average removal rates of COD were 41.5%,40.5% and 40.9%, respectively. Obviously, Canna indica is most effective on the removal of TN and TP. The experimental results prove that sewage treatment by the canna artificial floating island has broad application prospects.
