This invention relates to a detoxification method for simultaneously removing dioxins and heavy metals from waste incineration fly ash. The method includes fly ash pretreatment and simultaneous removal of dioxins and heavy metals. First, sodium and potassium salts are removed from the fly ash by immersion washing to avoid reducing the ability of the sintered products formed during high-temperature sintering to solidify heavy metals. Then, the pretreated fly ash is separated to obtain a solid phase, which is mixed with magnesium and / or calcium salts and subjected to high-temperature roasting. This allows the chlorine from the decomposition of dioxins in the fly ash to react with the heavy metals to form gaseous heavy metal chlorides, thus removing the heavy metals from the fly ash. During the high-temperature roasting process, the magnesium and / or calcium salts react with the ash in the fly ash to form calcium silicate and / or magnesium silicate, enhancing the solidification ability of the internal lattice of the fly ash sintered products. After detoxification treatment of waste incineration fly ash using this method, no heavy metals Hg, Pb, Cd, Cu, and Ni were detected in the fly ash leachate, significantly reducing the leaching risk of residual heavy metals in the fly ash.
