摘　　要：采用两级逆向垂直潜流人工湿地去除污水中的营养物质.一级人工湿地以连续流方式进水,NH4-N平均去除率为30%,TP平均去除率为62%,硝化和反硝化作用不明显.二级人工湿地中,NH4-N平均去除率为98.6%,TP去除率为100%;硝酸盐氮平均为19.5mg/L.二级人工湿地进行的是硝化过程,而少有反硝化过程.This research applied two-stage inverse vertical subsurface flow constructed wetlands to removal nutrients in wastewater. The first stage CW was fed continuously, averaged NH4-N and TP removal rates were 30 96 and 62 %, individually, no obvious nitrification and denitrification. In the second stage CW, averaged NH4-N and TP removal rates were 98.6 % and 100 %, individually; NO3-N concentration averaged 19.5mg/L, no significant denitrification.
