摘要
采用生态填料人工湿地作为构筑物对某生态村中心湖的微污染水体进行处理.结果表明:此工艺对浊度的去除率在70%～94%之间,对化学需氧量(CODCr)的去除率为20%～50.2%左右,总磷(TP)的浓度去除率为50%～90%,总氮(TN)的浓度去除率为41.2%左右,达到或优于国家三类水质标准.
The micro-polluted water of the center lake in some ecological village is treated by using arts and crafts of constructed wetland with ecological padding. The results show that the turbidity removal of 70%-94%, CODcr removal of 20%-50.2%, the concentration of TP removal rate about 50%-90% , the removal rate of TN concentration about 41.2%, and these indexes of the treated water reach or exceed band 3 national water quality standard.
