城市生活垃圾焚烧飞灰中重金属污染与控制

Pollution and Control of Heavy Metals in Fly Ashes from Municipal Solid Waste Incinerator

针对城市生活垃圾焚烧飞灰中的重金属污染问题,介绍了焚烧飞灰中重金属生成机理及来源,并重点阐述了国内外对焚烧飞灰中重金属的稳定化处理方法及控制措施,为垃圾焚烧飞灰的无害化、资源化处理提供了必要的理论参考,并提出了未来垃圾焚烧飞灰中重金属污染物处理的发展方向。

According to the pollution problems of heavy metals in fly ash from municipal solid waste （MSW） incinerator, the origin and formation mechanics of heavy metals pollution, in waste incineration process were introduced. The methods of fly ash treatments and disposal for MSW incineration at home and abroad have been presented, the fly ash stabilizing methods for MSW incineration being emphatically expounded. These results would provide necessary theory reference for the harmlessness and resource recovery of fly ash. Mean while, the development direction of the treatment for heavy metals in fly ash treatment from MSW incinerator in the future would be put forward.
