| 摘 要： | 测定由不同植物构成的人工湿地的氨态氮、硝态氮和亚硝态氮含量,对比不同植物对生活污水中氮的去除效率.结果表明,与不种植物的人工湿地相比,由风车草Cyperus alternifolius L. ssp. flabelliformis (Rottb.) Kiikenth.]、香根草Vertiveria zizanioides (Linn.) Nash]、芦苇(Phragmitas communis Trin.)和美人蕉(Canna indica Linn.)构成的人工湿地对氨态氮去除率分别提高6%、8%、11%和14%;对硝态氮去除率分别提高5%、6%、13%和9%;对亚硝态氮去除率分别提高5%、7%、10%和7%,说明种植芦苇和美人蕉的人工湿地对生活污水中的氮具有较好的去除效果.

| Abstract: | The contents of NH_(4)~(+)-N,NO_(3)~(-)-N and NO_(2)~(-)-N in constructod wetlands planted with different plants were determined to contrast the nitrogen removal effect in domestic sewage.Compared with the wetland with no plant,in the wetlands with Cyperus alternifolius L.ssp.flabelliformis(Rottb.) Kiikenth.,Vertiveria zizanioides(Linn.) Nash,Phragmitas communis Trin.and Canna indica Linn.,NH_(4)~(+)-N removal ratios increased 6%,8%,11% and 14% respectively;NO_(3)~(-)-N removal ratios increased 5%,6%,13% and 9% respectively;and NO_(2)~(-)-N removal ratios increased 5%,7%,10% and 7% respectively.The results show that the wetlands planted with P.communis and C.indica have better effect of nitrogen removal in domestic sewage. |
