摘要
成都市活水公园人工湿地塘床系统对枯水期府河水中的CODCr,BOD5,TN ,TP ,oil,LAS ,Ar -OH ,NH3,S2 - 等污染物的去除率在 85%以上 ,总大肠菌群的去除率达 99 9%以上 ,其净化效果能够满足净化地表水或污水深度处理的需要。由此可见 ,人工湿地塘床系统是一种生态滤池。
In the constructed wetland pond-bed system in Living Water Garden at Chengdu,the removal rates of COD,BOD,T-N,T-P,oil,LAS,Ar-OH,NH 3 and S 2- are more than 85% and for total coliforms is more than 99 9%,in which purification efficiency can be qualified for purifying polluted surface water or doing tertiary treatment So the constructed wetland pond-bed system is an ecological filter
