摘　　要： 全面介绍垃圾焚烧炉中二噁英生成机理的研究进展。研究表明,从头合成反应和前驱物异相催化反应是形成二噁英的最主要反应,其影响因素包括温度、反应的烟气环境、氧量、氯源、催化剂等;无论哪一种非均相反应,都可以归结为飞灰表面的异相催化反应。控制和减少垃圾焚烧炉二噁英的生成和排放,必须从上述主要影响因素着手。 The advancements in study on formation mechanisms of dioxin in municipal solid waste (MSW) incinerators have been completely presented. Studies show that the de novo synthetic reaction and the outphase catalytic reaction of the precursors are the must major ones for formation of dioxin. The influence factors include temperature, flue gas atmosphere of said reactions, oxygen content, chloride source, and catalysts etc.. Regardless of which nonhomogenous reaction occurred, it can be considered as outphase catalytic reaction on the surface of fly ash. In order to control and reduce the formation and emission of dioxin from MSW incinerators, the said main affecting factors should be set about.
