摘要
设计了垂直流+水平流、水平流+垂直流、单一水平、单一垂直等4组不同结构的人工湿地组合,研究其对生活污水的净化效果。结果表明:4组人工湿地对CODCr,TP的去除率分别达到80%,70%左右;对TN的去除,垂直+水平单元去除率最高,为44.30%。
Four different lab plants of constructed wetlands were used to treat domestic wastewater. It was made up of vertical flow constructed wetland connected with subsurface flow constructed wetland （VW1＋SSW1）, SSW2＋VW2, single SSW3 and single VW3. The results showed that the four different lab plants had higher removal rate of CODCr and TP, it was about 80% and 70%, respectively. And VW 1 ＋SSW 1 had the highest removal rate of TN in the four different lab plants, which was 44.3%.
