摘要
以河北邯郸滏阳河水为例,构建两组不同类型的人工湿地来处理城市污水,探究适合华北地区处理城市污水的人工湿地类型。经由实验测定结果显示,复合型人工湿地对污水处理效果较好,两组人工湿地对TN、TP、浊度、CODMn的去除率分别为41%、96%、92%、57%和27%、89%、88%、44%。基质填料限制了湿地对污染物的去除,建议采用沸石、煤渣或者组合基质,以增加湿地污染物去除效果。此外,植物的选择也影响着湿地对污染物的去除效果。
In order to find a form of wetland which works best in the treatment of wastewater of Hua Bei,Fu Yang River as samples,To build two different complex constructed wetland. The study show： the complex constructed wetland wastewater treatment better. And the two constructed wetland＇s removal rate of the TN,TP,turbidity,CODMn are 41%,96%,92%,57% and 27%,89%,88%,44%. The matrix limits the removal of pollutants. In order to solve the question.,it is a recommend to introduce zeolite matrix,cinder,and with gravel matrix together as a combination matrix,or introduce the plants which have a better ability of nitrogen removal.
