摘　　要： 城市生活垃圾成分复杂 ,并且焚烧过程中会产生重金属的二次污染 ,是城市垃圾处理中最难解决的问题。对此 ,从垃圾重金属的来源 ,重金属在垃圾焚烧过程中的迁移和转变特性 ,以及重金属在焚烧过程中迁移分布的影响因素等方面进行研究。研究认为 ,重金属在焚烧炉中的最终分布除了受本身特性(蒸发压力和沸点 )影响外 ,还与原生垃圾组成以及焚烧环境有关。 Because of the complex composition in MSW, secondary pollution of heavy metals in the process of MSW incineration is the most difficult problem to be solved in MSW disposal. Then, the influence factors in many aspects, such as the sources of heavy metals the characteristics of transfer and conversion of heavy metals in the process of MSW incineration, as well as the mechanisms of heavy metal transfer and distribution in the said process etc., have been studied. Results of study show, the final distribution of heavy metals in the incinerator was influenced by the characteristics of the heavy metals proper (i. e. Pressure of vaperization and boiling point), in addition, it is also related with the original composition of MSW and the environment of incineration.
