生活垃圾焚烧中重金属行为的研究进展

垃圾中的金属以氧化物、氮化物、碳化物及其它形态转移到焚烧产物如烟气、飞灰和底灰中，需严格控制焚烧过程中重金属的排放，故清楚了解金属在焚烧中的行为是很必要的。经研究发现，飞灰中重金属含量远远大于底灰中的含量，因此以垃圾焚烧飞灰中重金属的稳定化处理为目标，分析了目前国内外处理垃圾焚烧飞灰的方法和重金属在各种影响因素下的行为，并进行了比较，为飞灰的无害化和资源化处理提供参考。

Development of Study on Behavior of Heavy Metals in Municipal Solid Waste

The heavy metals in terms of oxide,nitride,carbide and other forms transfered to production of incineration(such as flue gas,fly ash and bottom ash).Most of metal ground states formed from incineration process were toxic,the discharge needed to be controlled strictly.So,it was necessary to understand the behavior of heavy metals in incineration process.It was studied that the quantities of heavy metals in fly ash were more than in bottom ash,thus this paper aimed to list stabilized treatments of heavy metals in incineration process,some methods of treating with fly ash and the behavior of heavy metals under every effects were analyzed;meanwhile,comparing with these treatments,which supplied the theory basis for harmless and resource treatment of fly ash.
