摘　　要：介绍了二噁的性质、危害和来源,从垃圾焚烧二噁产生的机理出发,探讨了其在垃圾焚烧过程中产生的3种途径,讨论了控制机理。介绍了垃圾热解工艺,由于热解机理对二噁的生成具有极大的阻尼作用,产生的二噁含量极低,可以大大地简化烟气的处理装置。Character,harm and source of dioxin were introduced,three ways of dioxin production in waste incineration process and control mechanism were discussed based on dioxin production mechanism in waste incineration.Pyrolysis process of waste was introduced,flue gas treatment facilities could be greatly simplified because of pyrolysis mechanism having enormous damping action on dioxin production,producing minute quantity dioxin.
