摘　　要：填埋是生活垃圾处理的主要方式之一,渗滤液导排系统结垢是国内外生活垃圾填埋场面临的普遍问题,受到越来越多的关注。影响渗滤液导排系统结垢的因素复杂多样,近年来由于焚烧炉渣大量进入填埋场混填给渗滤液导排系统造成了新的挑战,因此亟需对相关研究进展进行系统的归纳和总结。从填埋场导排系统淤堵、导排组分结垢(土工布、颗粒材料、管道)、结垢形成机制(物理、化学、生物)以及填埋场结垢新挑战等方面,对国内外相关研究进展进行综述,从而为填埋场导排层防淤堵及科学设计提供必要的参考信息。Landfill is the most commonly used method for municipal solid waste(MSW)treatment.However,clogging in leachate collection system(LCS)was a common problem in landfills around the world and has attracted more and more attention.The factors affecting the clogging in LCS are complex and diverse.In recent years,a large number of incineration bottom ash was disposed in landfills,posing new challenges to LCS clogging.Therefore,it is urgent to systematically conclude and summarize relevant research progress.In this review,the components of LCS clogging were reviewed.Different parts of LCS clogging were compared,including geotextile,gravel,and pipe.The mechanisms of clogging were also analyzed,for instance,physical,chemical,and biological clogging.These findings will provide useful information for the control and mitigation of clogging in landfill LCS.
