摘要
在东大河入滇池河口处利用11个废弃鱼塘构建湖滨湿地44741m2,研究了湿地对入滇池河水的净化效果。结果表明,湿地正常运行时,对COD、TN、TP、SS具有较好的净化效果,系统稳定时的去除率分别可达到64.71%、41.48%、47.44%、90.56%。本湿地系统完全自流,不消耗动力,为进入湖泊的河道污水净化、保障入湖河水的水质,提供了一条新的技术支撑。
An area of 44741m^2 wetland was constructed by 11 abandoned fish ponds in Dongdahe River lakeshore, the estuary of Dianchi Lake. The efficiency of purifying river water flowing into Dianchi Lake by the wetland was analyzed. It was shown that the west side wetland had a good purification effect on river water when it arrived in the normal running condition and then the removal rate of COD, TN, TP and SS could reach at 64.71% ,41.48% ,47.44% ,90.56% respectively. The running of the wetland system is completely by auto-flowing and non-power consumed. The system also offered a new technology support for purifying river sewage and protecting the quality of river water that flowed into lakes.
