摘　　要：垃圾焚烧飞灰已被明确规定为危险废物,必须经过合理的处理才能填埋。介绍了近年来国内外对飞灰处理的研究进展,重点从水泥固化、玻璃化/熔融固化、化学药剂稳定法3个方面对飞灰的处理进行论述,并对比分析了各项技术的优缺点,突出阐述了飞灰的资源化利用,最后对飞灰处理的发展前景进行了展望。Disposal of MSWI fly ashes into ordinary landfill sites poses serious environmental problems. MSWI fly ashes are considered as hazardous in accordance with the stringent regulations and should be properly treated before landfilling. Current treatment technologies for MSWI fly ashes are introduced. Three kinds of fly ash disposal methods including cement solidification, melting/vitrification and chemical stabilization processes are highlighted. The merits and drawbacks of three methods are compared. The reuse of MSW1 fly ashes is distinctly presented. Finally, the prospects of the treatment of fly ashes are put forwards.
