| 摘 要： | 通过微氧+人工湿地组合工艺对生活污水处理效果的研究,认为该工艺是比较适合农村生活污水处理应用的工艺组合。微氧预处理对COD的平均去除率在30%以上,人工湿地水力负荷为0.2 m3/(m2.d),对COD的平均去除率在60%以上,对NH3-N的平均去除率在30%～40%,该工艺组合的运行费用为0.15～0.20元/t(污水自流进入系统情况下)。

| Abstract: | We do the study on the effect of combined technology of low DO pre-treatment and constructed wetland for treating domestic wastewater.The results show that this combined technology is suitable for treating rural domestic wastewater.In this study,the average removal rate of COD removed by low DO pre-treatment is above 30%,the hydraulic loading of constructed wetland is 0.2 m3/(m2·d),which could remove more than 60% COD averagely,the average removal rate of NH3-N is between 30% and 40%.The running cost of this system is between 0.15 yuan/m3(no pump in the system)and 0.20 yuan/m3. |
