摘要
以北京的清河为对象，进行人工湿地治理滞留型景观河道污染的示范工程研究。运行结果表明：在水力负荷为0．8～1．2m／d的条件下，人工湿地对COD、NH3-N、TN、TP、藻类和浊度的去除率分别维持在35％～74％、60．5％～88．3％、56、3％～80．5％、30．4％～71．1％、83．6％～91．5％和85．2％-95％。在人工湿地每天运行6h的条件下，示范河段的水质得到了有效的改善，控制了“水华”现象的发生。
Qinghe river is a typical detention landscape urban river of Beijing. Pollution control of this river by subsurface flow constructed wetland was studied. The industrial scale experimental results showed that the removal rates of COD, NH3 - N, TN, TP, algae and turbidity were 35% - 74%, 65.5% -88.3%, 56.3% -80.5%, 30.4% -71.1% 83.6% -91.5% and 85.2% -95% , respectively, with the hydraulic loading rates of 0. 8 - 1.2 m/d. Under the condition of 6 h runtime everyday, water quality of the experimental river was improved effectively, and algae bloom was abstained.
