Pre-dechlorinating-sintering treatment technology for high-chlorine metallurgical waste and incineration fly ash

The invention discloses a pre-dechlorinating-sintering treatment technology for high-chlorine metallurgical waste and incineration fly ash. The technology comprises the processes that high-chlorine metallurgical dust sludge, waste incineration fly ash and carbonaceous fuel are mixed uniformly and then pressed into block masses after the water content is balanced by adopting chlorine-containing wastewater; the obtained block masses are arranged in an oxygen-deficient atmosphere to be subjected to roasting pretreatment, and roasting block masses are obtained; and the roasting block masses serveas an iron ore sintering bottoming material to participate in sintering. According to the technology, pollution of chlorine and dioxin in the solid waste sintering process is reduced through roastingpretreatment, resource utilization of components such as Fe, Ca and C in the solid waste such as the high-chlorine metallurgical dust sludge and the waste incineration fly ash is achieved, and meanwhile reuse of the chlorine-c
