人工湿地系统在垃圾渗滤液处理中的应用

Application of Constructed Wetland in Landfill Leachate Treatment

介绍了人工湿地的组成和类型,人工湿地去除渗滤液中有机物、氮、磷和重金属的机制。分析了影响人工湿地处理渗滤液效率的因子,并且结合人工湿地设计和运行维护提出了相关建议。根据国内外成功的工程实例,分析了人工湿地处理垃圾渗滤液的经济优势、生态优势,展示了该处理技术广泛的应用前景,对以后的研究进行了展望。

This paper comprehensively introduced the constitution and types of constructed wetland,Mechanisms of removing organic matter,nitrogen,phosphorus and heavy metals from landfill leachate by constructed wetland anti the factors affecting the removal efficienc, y also were discussed. Some suggestions about design and operation of constructed wetland for landfill leachate were also presented in this paper, Meanwhile, the economic advantages and ecological advantages of constructed wetland in landfill leachate treatments were analyzed by the domestic and foreign successful examples,At last, the prospects of researches in this field were put forward.
