垃圾渗滤液处理技术及工程化发展方向

Landfill Leachate Treatment Techniques and Engineering Development Direction:A Review

渗滤液水质特性复杂,含有大量COD、氨氮、重金属等有毒有害物质,国内外学者进行了广泛的实验室及工程化应用研究。文章介绍了不同来源的渗滤液的水质特点及目前国内具有代表性的4种工艺组合路线,分析了国内主流渗滤液处理技术面临的问题,并提出了工程化应用研究发展的方向。

The composition of the landfill leachate is complex,which contains high strength of COD,ammonia nitrogen and heavy metals.Lab and industrial scale tests of landfill leachate treatments have been widely carried out by researchers all over the world.In this study,water quality characteristics of landfill leachate from different sources and four typical integrated treatment process routes utilized in China were introduced.This paper reviewed the main drawbacks of the current treatment techniques and proposed perspectives for future researches.
