Abstract
针对农村生活污水处理难、基建投资成本高、技术复杂等问题,以广州市岑村河污水为例,开展了农村生活污水排放期间种植皇竹草(Pennisetum sinese Roxb)和美人蕉(Canna indica L.)处理污水的静态试验.结果表明,与不种植植物的对照相比,种植皇竹草和美人蕉处理的总氮(TN)、总磷(TP)的去除率分别提高了43.01、41.70和61.62、60.44个百分点,且种植皇竹草对污水的净化效果优于种植美人蕉,皇竹草对污水中化学需氧量(COD)、总磷、氨氮、总氮的去除率分别为79.86%、99.83%、98.86%、98.14%,而美人蕉则分别为57.51%、98.65%、98.18%、96.83%.
