| 摘 要： | 将垂直流人工湿地与水平流人工湿地组成复合人工湿地系统，研究了此复合系统对化粪池出水的净化效果。结果表明，当水平流人工湿地的水力停留时间为3d天时，复合系统对COD、BOD5、TP的去除率分别达到73％、66％、87％，并通过垂直流湿地的硝化作用及水平流湿地的反硝化作用，复合系统对TN的去除率达到40％以上。

| Abstract: | The vertical-flow and horizontal-flow beds were combined to hybrid constructed wetlands systems,and its purification efficiency for septic tank effluent was studied.The results showed that while the hydraulic retention time of horizontal-flow constructed wetlands was three days,the average removal rates of COD,BOD5,TP were 73%,66%,87%,respectively.And the average removal rate of TN was over 40% through the nitrification in the vertical-flow constructed wetlands and the denitrification in the horizontal-flow... |
