| 摘 要： | [目的]研究不同填料潜流湿地对污染物的处理效果,为小城镇河网水体修复提供依据。[方法]研究了砾石、卵石、页岩3种不同填料潜流湿地对受污染河道水质修复的运行情况及处理效果。[结果]砾石、卵石、页岩填料湿地对受污染水体中TN、TP、CODMn均有较好的去除效果,其中砾石床潜流湿地运行效果最好,平均可分别处理49.4%的TN、34.7%的TP及48.5%的CODMn。[结论]潜流人工湿地可以有效改善受污染河道水质,且投资少、操作简单,适于在小城镇推广。 |

| Abstract: | Constructed wetland can be operated for river rehabilitation with high efficiency,low investment and low energy consuming.It is important to the small town waste water treatment.This paper mainly introduces the different run condition and removal performance of 3 media subsurface wetland which treats polluted rival water.the 3 media include gravel、cobblestone and shale.The experimental results showed that all media subsurface wetland can effectively lower the nitrogen,phosphorus and chemical oxygen demand in polluted rival.The gravel media subsurface wetland showed the best removal performance,which can lower the 49.4% of total nitrogen,34.7% of total phosphorus and 48.5% of chemical oxygen demand respectively. |
| Keywords: | Subsurface constructed wetland Polluted river water Gravel Cobblestone Shale |
