摘　　要：污水经酸化预处理后进入两级垂直潜流人工湿地,进行间歇流运行。实验结果表明,一级人工湿地面积有机负荷率5.52～11.7gCOD/(m2.d),COD去除率大于60%;二级人工湿地有机负荷率5.87～8.7gCOD/(m2.d),COD去除率大于70%,总去除率大于90%。一级人工湿地NH4N负荷率0.25～0.94gNH4N/(m2.d),NH4N去除率大于60%。二级人工湿地NH4N负荷率0.68～0.83gNH4N/(m2.d),NH4N去除率大于70%,总去除率大于92%。Research was conducted on two stage vertical subsurface flow constructed wetlands （CW） for synthetic domestic wastewater treatment. Synthetic domestic wastewater was treated in a pre-acidification reactor. In the first stage CW, under organic loading rate （OLR） of 5.52 - 11.7 g COD/（m^2.d）, COD removals was more than 60%; under OLR of 5.87 - 8.7 g COD/（m^2.d）, the second stage CW COD removals was more than 70%; total COD removal of the system was greater than 90%. Under 0.25 - 0.94 g NH4-N/（m^2.d）, the first stage CW got NH4-N removal of more than 60%; under 0.68 0.83 g NH4-N/（m2.d）, the second stage CW also got higherNH4-N removal of more than 70%, total NH4-N removal of the system was greater than 92%.
