| 摘 要： | 采用改变湿地构型、不同进水方式和曝气运行3种方法,开展不同运行方式对人工湿地的强化除磷效果研究。结果表明:垂直流湿地TP的去除率比水平流湿地平均高10%左右,串联方式对改善人工湿地系统除磷效果不明显,而当水平流湿地多点进水的配水比为2∶1∶1时,湿地对TP的去除率可上升5%～10%。湿地间歇运行当停置时间为2d时,TP去除率可提高6%左右;人工湿地曝气运行当气水比为6时,总磷去除率可达到最大。湿地间歇进水、曝气运行方式都可一定程度地提高湿地除磷效率,但要综合考虑对其他主要污染物的去除效果及系统运行费用影响。

| Abstract: | The experiment took three measures including ameliorating structure,changing inflow way and aerifying to research the influence of constructed wetlands for intensifying phosphorus removal.The results showed that when wetland was constructed in vertical structure,the phosphorus removal rate was about 10% more than that of horizontal flow wetlands;when the ratio of inflow was 2∶1∶1 on multi-inflow wetland,the phosphorus removal rate rose by 5%～10%;when intermission-infow wetlands paused for 2d,the phosphorus removal rate rose by 6%;when gas-water ratio was 6 on aerifying wetlands,the phosphorus removal rate reached the maximum.Intermission-inflow and aerifying constructed wetlands both intensified phosphorus removal,but the removal rate of other pollutant and running expenses should be consided as well. |
