摘要
城市垃圾对环境的影响越来越严重,垃圾填埋导致垃圾渗滤液的大量产生,渗滤液中含有大量的有机物、大量的病菌、病毒、寄生虫等以及一些有毒有害的物质,若渗滤液不加以妥善处理、肆意排放,必将对地下水、地表水构成严重威胁,因此垃圾渗滤液的有效处理就成为一个亟待解决的问题。本文对城市垃圾填埋场渗滤液的处理工艺进行了分析和探讨,介绍了国内外垃圾渗滤液处理的主要技术,包括土地处理法、生物法和物化法,并对电解法处理垃圾渗滤液进行了详细的介绍。
The influence of municipal solid wastes （MSW） on the environment is more and more serious. The landfill of MSW causes the production of a great deal of leachate. The leachate contains a lot of organic matters, germina, virus, parasite and some poisonous and deleterious matters. If it is released freely without any proper disposal, it will cause serious threaten to ground water and surface water. Therefore how to treat the leachate becomes a serious problem. In this paper the treatment processes home and abroad of landfill leachate was introduced and discussed, including land treatment, biological treatment, physical-chemical treatment and, especially, the electrolysis treatment.
