生活垃圾焚烧飞灰处理处置与资源化技术研究进展

Research Progress on Treatment and Recycling Technology of Domestic Waste Incineration Fly Ash

生活垃圾焚烧飞灰成分复杂,含有各种可能对环境构成明显危害的重金属元素和二噁英类物质,需进一步进行无害化处置。介绍了目前主要的生活垃圾焚烧飞灰处理技术的进展,如固化技术、稳定化技术及填埋技术中组合工艺、高温熔融处理技术、水泥窑协同处置技术等,分析各项技术存在的优点、缺点,并对生活垃圾焚烧飞灰相关处理处置技术的发展方向进行了展望。

The composition of Municipal Solid Waste Incineration(MSWI)Fly Ash which contains harmfulcomponents such as heavy metals and dioxins is complex,further harmless disposal is required.The main treatment technologies of MSW incinerationfly ash at present,such as cement solidification,chemical stabilization andmelting solidification,were introduced and analyzed,the development of therelated treatment and disposal technologies of MSW incineration fly ash were prospected.
