In order to control dioxins (PCDD/Fs) which produced during the incineration process of municipal combustible solid waste,the generation mechanism such as high temperature gas-phase synthesis,precursor synthesis and de novo synthesis was introduced. The present situation and development trend of control technologies were discussed. The analysis shows that, according to the mechanism in the existing research, the factors affecting the synthesis of dioxins include combustion conditions, chlorineand metal elements. In the first, middle and last stages of incineration, it is suggested to apply classification and screening,process parameter control, and adsorption dedusting, respectively, to prevent the generation of dioxins or treat dioxins.
