摘　　要：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%。In response to the difficulties in rural sewage treatment,high investment costs in infrastructure,and complex technology,the static test of wastewater from sewage treatment in the Cencun river,Guangzhou city,was carried out to simulate the discharge time of rural household sewage,and the treatment of sewage with the planting of Pennisetum sinese Roxb and Canna generalis L.was conducted.The results showed that compared with the control treatment,the removal rates of ammonia nitrogen,total nitrogen(TN)and total phosphorus(TP)of planting Pennisetum sinese Roxb and Canna generalis L.increased by 43.01,41.70 and 61.62,60.44 percent,respectively,and the treatment of Pennisetum sinese Roxb was better than the treatment of planting Canna generalis L..The removal rates of COD,TP,ammonia nitrogen,and TN in wastewater of Pennisetum sinese Roxb were 79.86%,99.83%,98.86%and 98.14%,respectively,while the Canna generalis L.was 57.51%,98.65%,98.18%and 96.83%,respectively.
