人工湿地植物对污水的处理效果研究

Study on Sewage Disposal Effect by the Manual Wetland Plants

为研究人工湿地植物对北京未来科技城污水处理的效果,以芦苇、水葱、泽泻、香蒲、荷花和凤眼莲6种常见的挺水植物为研究对象,设计了2个阶段的试验。结果表明,芦苇、香蒲和凤眼莲组合最好,对COD,BOD5和氨氮的去除率分别达到69.2%,47.6%和54.4%,综合净化能力最强。

To study sewage disposal effect in Beijing Future Science City by the manual wetland plants,in this paper the Phragmites australis,Scirpus validus,Alisma plantago,Typha orientalis,Nelumbo nucifera and Eichhornia crassipes were used in a two-phase experiment to choose three top purifying capacity plants in the local soil and hydrology environment.In the result,Eichhornia crassipes,Phragmites australis and Alisma plantago showed the best purifying capacity with a removal rate of 69.2%,47.6%,54.4%,respectively.
