| 摘 要： | 对比了四种复合人工湿地系统对化粪池出水COD、TP、NH3-N和SS的净化效果,试验系统均采用间歇式进水,时间间隔为1d。为期7个月的运行结果表明,系统出水水质均达到城镇污水处理厂污染物排放标准(GB18918-2002)中的二级标准,其中潜流(水平流)+垂直流(上行流)湿地系统对COD的去除效果最好;垂直流(下行流)+垂直流(上行流)湿地系统对TP、NH3-N、SS去除效果最好;选用含钙石灰石和含铁矿粉做填料、采用间歇式的运行方式可以提高湿地系统对污染物的去除率。

| Abstract: | Under batch-flow conditions,some parameters including COD,TP,NH3-N and SS were measured with 1day internal in 4 combined artificial wetlands.Results of 7 months operation showed that the effluent can meet Grade II of discharge standard of pollutants for municipal wastewater treatment plant GB18918-2002.In which the removal efficiency of COD was the best in subsurface flow(horizontal flow)and vertical flow(upward flow)constructed wetland system,while removal efficiency of TP,NH3-N and SS were the best in the... |
