摘　　要：湿地污水处理技术的研究是国内外众多学者关注的热点之一。综合国内外在污水湿地处理技术方面的研究成果,对湿地生态系统及其各组成要素对重金属污染的修复作用及其作用机理进行了讨论,针对目前利用湿地生态系统进行重金属污染废水修复过程中应注意的几个问题进行了探讨,并对今后研究发展方向进行了评述。Because of the advantages of low cost, low energy consumption, high treatment efficiency, simplicity of operation and maintenance etc.,wetland ecosystem is globally used in wastewater treatment (especially in rural areas and small cities). On the basis of existing results of removal mechanism of heavy metal in wetland ecosystem, A few key issues in the use of wetland ecosystem in wastewater treatment and the potential trend of the study have been comprehensively discussed and reviewed, which is of great significance to the future studies.
