| 摘 要： | 目前,水稻种植面积大,氮、磷流失严重,引起湖泊富营养化。芦苇能经济高效去除氮、磷等有机物。研究表明,对NH4+-N的去除效果可达89.4%,对COD的去除效果可达81.2%,对TN和TP的去除率分别为86%和74.4%。因此表面流芦苇湿地系统去除稻田排水中污染物具有良好的前景。处理方法符合目前水环境生态保护趋势要求。

| Abstract: | At present,b ecause large area of rice planting,nitrogen and phosphorus serious loss caused Lake Eutrophication. The reed is one kind of plant which can removal nitrogen,phosphorus organic compounds economically and efficiently. The result showed that NH4+-N removal up to 89.4% ,COD removal up to 81.2% ,the removal rate of TN and TP was up to 86% and 74.4%. So the surface flow bulrush wetland system has good prospects in removing pollutants of rice fields drainage. The water treatment method accords with th... |
