摘要：

通过在北京翠湖构建人工湿地来处理污染水体，研究该人工湿地对pH、浊度、CODcr、TN、TP的去除作用。从人工湿地对污染物的去除效果来看，浊度、CODcr、TN和TP运行3月的平均去除率分别为42.659%、7.161%、25.583%和24.662%。结果表明，翠湖人工湿地处理的水体中pH随时间变化而有所降低，出水口pH值逐渐得到改善。翠湖人工湿地5个不同时间段（2009-6-3、2009-6-26、2009-7-9、2009-7-29、2009-8-17）浊度的平均去除率分别为66.459%、62.562%、33.343%、6.616%、44.314%。翠湖人工湿地对CODcr的去除率随时间变化有较小波动，5个时间段平均去除率分别为4.347%、4.716%、10.748%、9.370%、6.622%。TN平均去除率分别为15.465%、27.669%、30.507%、33.177%、21.098%，TP平均去除率分别2.688%、49.790%、21.538%、13.580%、35.714%。

Abstract:

The wastewater treatment effect of pH, turbidity, CODcr, TN, TP had been studied by the constructed wetland in Cuihu wetland, Beijing. From the operation effect, the average removal of turbidity, CODcr, TN and TP was 42.659%, 7.161%, 25.583%, 24.662% respectively after 3 months. The results showed that pH decreased with time, the outlet value of pH was gradually improved. The average Turbidity removal rate was 66.459%, 62.562%, 33.343%, 6.616%, 44.314%, respectively in 5 different periods (2009-6-3, 2009-6-26, 2009-7-9, 2009-7-29, 2009-8-17). The removal of CODcr had less fluctuation over time, removal rate was 4.347%, 4.716%, 10.748%, 9.370%, 6.622% respectively in Cuihu constructed wetland. The average TN removal rate was 15.465%, 27.669%, 30.507%, 33.177%, 21.098% respectively. The average TP removal rate was 2.688, 49.790%, 21.538%, 13.580%, 35.714% respectively.
