垃圾焚烧飞灰处置与资源化利用研究进展

Progress of Disposal and Utilization of Fly Ash from MSW Incineration

针对作为危险废物的垃圾焚烧飞灰,系统介绍了国内外对其进行处理处置的现状,从水泥固化、高温稳定化及化学药剂稳定化几方面进行了论述。在总结目前国内外飞灰资源化利用途径的基础上,介绍了其4类再利用途径:建筑材料制作(水泥、混凝土、陶瓷、玻璃和玻璃陶瓷),农业利用(土壤改良剂)、岩土工程应用(道路、筑堤)和其它(吸附剂),并对以后的处理方向作了阐述,为飞灰的无害化和资源化处理提供参考。

Fly ash from waste incineration is one kind of hazardous wastes.This paper introduces the treatment of fly ash from municipal solid waste incineration at home and abroad,and discusses from perspective of cement solidification,melting solidification and chemical solidification.Based on summaries of current fly ash resource utilization researches at home and abroad,four application ways were discussed：construction materials（cement,concrete,ceramics,glass and glass-ceramics）,agriculture（soil conditioner）,geotechnical engineering（pavement,embankments）and miscellaneous（sorbent）.
