采用2种复合人工湿地系统处理昆明市城市河流污水,为期1年的运行结果表明:2种复合人工湿地系统对城市河流污水具有良好的污染物去除性能,TN、TP、COD和ss的月平均去除率分别达到50%、85%、85%和80%以上;2种复合人工湿地系统具有良好的耐冲击性,季节变化对出水水质不存在显著影响.其中,垂直上行流复合人工湿地系统性能更优于垂直上行流与水平流复合人工湿地系统;强降雨会对复合人工湿地出水水质造成一定的影响.

Two kinds of integrated constructed wetlands were used for the treatment of polluted fiver water in Kunming city. The results showed that the two integrated constructed wetland systems had good purification efficiencies for polluted urban river water, the monthly average removal rates of TN, TP, COD and SS were more than 50%, 85%, 85% and 80%, respectively. The two integrated constructed wetland systems could suffer high hydraulic loading rate shock, and seasonal variation of climate in Kunming city had no significant influence on the effluent quality of the two integrated constructed wetlands. The performance of vertical up-flow with vertical up-flow constructed wetlands was better than that of vertical up-flow with horizontal flow constructed wetlands.Heavy rainfall could affect the effluent quality.
