摘　　要：在目前对生态污染下的湿地水体污染的修复中,对生态的自然平衡不够重视,导致修复后的水体中营养物质失衡。因此提出非点源水生态污染下湿地污染水体修复措施。首先运用电渗透和电迁移原理移除水体中的难溶金属形态物质进行沉淀。将水体通过曝气生物滤池,运用微生物的氧化降解,处理水体有机物。添加异相Fenton催化剂,对水体中的有机物进行催化反应,最后将处理好的水体引入至人工湖,完成污染水体的修复。实验结果显示设计的修复措施修复后的水体,有机物含量更平衡,满足标准。In the current restoration of wetland water pollution,there’s a lack of attention for the ecological balance,resulting in an imbalance of nutrients in the restored water body.Therefore,the restoration measures of wetland polluted water body under non-point source water ecological pollution are proposed.First,the principles of electroosmosis and electromigration are used to remove the insoluble metal form substances in the water body for precipitation.The water body is passed through the aerated biological filter,and the oxidative degradation of microorganisms is used to treat the organic matter in the water body.Heterogeneous Fenton catalyst is added to catalyze the organic matter in the water body,and finally the treated water body is introduced into the artificial lake to complete the restoration of the polluted water body.The experimental results show that the water body after the designed restoration measures has a more balanced organic content and meets the standard.
