| 摘 要： | 为了处理农业径流的污染，本研究采用水平潜流人工湿地对农业径流进行处理试验,以减轻河流污染。结果表明，进水流量2.5m3/d运行条件下，水平潜流人工湿地有较好的处理效果。潜流人工湿地CODcr、TN、NH4+-N、TP的平均去除率均分别达到49.65%,51.37 %,56.24% 和59.12%；潜流人工湿地系统的出水CODcr、TN、NH4+-N、TP平均含量分别达到Ⅱ类水质的含量,Ⅴ类水质的含量, ,Ⅱ类水质的含和Ⅳ类水质的含量。通过对人工湿地处理系统影响因素分析表明：进水流量的控制非常关键，适宜的进水流量处理效果最佳。

| Abstract: | In order to treat agricultural runoff pollution and mitigate river pollution,Horizontal flow constructed wetland system was used to treat agricultural runoff in this study.Treatment results show that when the influent flux is 2.5 m 3 /d,horizontal subsurface flow constructed wetland has better purification effect,the removal efficiency of chemical oxygen demand（CODcr）,total nitrogen（TN）,ammonium nitrogen（NH 4 ＋-N） and total phosphorus （TP） in the horizontal subsurface flow constructed wetland were49.65%,51.37%,56.24% and 59.12%,respectively.Mean influent COD,TN,NH 4 ＋-N and TP were GradeⅡ,Grade Ⅴ,GradeⅡand Grade Ⅳ,respectively.After the disposal of the constructed surface wetlands,Mean effluent COD and Mean NH 4 ＋-N can nearly reach Grade Ⅰ.Mean effluent TP can nearly reach Grade Ⅰ.Mean effluent TN can nearly reach GradeⅣ.From the analysis of the impact factors in the constructed wetland systems,it can be seen that a key factor was to control the influent flux,and proper influent flux can obtain the optimum treatment effect. |
