Abstract：Domestic waste incineration fly ash which increased year by year in China is a typical refractory hazardous waste. Fly ash has caused significant environmental damage due to the presence of dioxins, heavy metals and chlorine. The sintering process with mature high temperature metallurgical technology and equipment has the potential to handle fly ash. According to the characteristics of fly ash and the sintering process, combined with the difficulties encountered in the treatment, the effects of adding fly ash on the sintering process, the metabolic of dioxins and heavy metals in the fly ash during the sintering process were discussed in this paper. The feasibility of co- processing fly ash with sintering process was confirmed, which provides references for fly ash handling companies and co- processing of solid waste using steel processes.
