垂直流与水平流人工湿地污水净化效果的对比研究

【摘要】 分别采用垂直流和水平流人工湿地处理城市生活污水,比较了两种构型湿地在不同停留时间和不同温度下对COD,TN,TP等主要污染物的去除效果。分析了湿地构型对净化效果的影响,为不同构型湿地在实际工程中的推广应用提供了参考。更多还原

【Abstract】 Vertical-flow and horizontal-flow constructed wetlands were used to treat urban sewage. Comparisons were made among some of removal efficiency of major pollutants (such as COD,TN and TP)under different HRT and temperature conditions in the two systems. The influence of construction on removal efficiency was analyzed,which is valuable for reference in the advance of constructed wetlands on different constructions.更多还原
