摘　　要：将人工湿地中潜流、表面流湿地进行组合用于处理河水。结果表明：人工湿地对水体改善具有很明显的作用,组合人工湿地COD去除率为66.7%-94.6%,BOD5去除率为58.6%-97.0%,SS去除率为20.0%-60.0%,氨氮去除率为50.0%-77.8%,总磷去除率为37.5%-88.9%。水体改善效果最好的为潜流—潜流人工湿地,其次为潜流—表流人工湿地,然后为表流—潜流人工湿地,最差为表流—表流人工湿地。Combinations of subsurface flow and surface flow in artificial wetlands were used in treating the water.The results showed that the artificial wetlands had a very significant role in improving water.In the combinations of artificial wetlands,the removal efficiency of COD was 66.7%-94.6%,BOD5was 58.6%- 97.0%,SS was 20.0%-60.0%,ammonia nitrogen was 50.0%-77.8%,total phosphorus was 37.5%-88.9%.The best effect of improving water was subsurface flow-subsurface flow wetland,the second was subsurface flow-surface flow wetland,the third was surface flow-subsurface flow wetland,and the worst was surface flow-surface flow wetland.
