Resource recycling method for preparing cementing material from incineration fly ash
The invention belongs to the technical field of hazardous waste resource utilization, and provides a resource recycling method for preparing a cementing material form incineration fly ash. Fly ash is encapsulated by an inorganic curing agent in a physical mode, the fly ash rich in heavy metal or chloride ions is cured/stabilized, mineral powder particles are wrapped with fly ash particles again, a waterproof inert protective layer is formed on the surface, and a new cementing material is generated. The whole production process is closed, low-temperature and high-temperature calcination and chemical reaction are avoided, zero discharge of solid waste is realized, and secondary pollution of pollutants is fundamentally solved.
本发明属于危险废物资源化利用技术领域，提供了一种将焚烧飞灰制备成胶凝材料的资源化再利用方法，采用物理方式用无机固化剂将飞灰包封起来，固化/稳定化处理富含重金属或氯离子的飞灰，矿物粉粒子重新裹覆飞灰粒子，表面形成一种不透水的惰性保护层，产生新胶凝材料，生产全过程密闭和低温，无高温煅烧和化学反应，固废零排放，从根本上解决了污染物的二次污染。
