Resource utilization method of waste incineration fly ash as well as product and application thereof
The invention discloses a resource utilization method of waste incineration fly ash as well as a product and application thereof, the waste incineration fly ash is added into zinc phosphating waste liquid to be soaked, solid-liquid separation and drying are performed, and modified waste incineration fly ash is obtained; the modified waste incineration fly ash, water and sodium silicate are mixed, stirred and cured, and the fly ash-based cementing material is prepared. According to the method, stabilization of heavy metal and removal of chlorine salt are achieved by cleaning the waste incineration fly ash through the zinc phosphating waste liquid, the heavy metal is further solidified in the mode that the fly ash-based cementing material is prepared from the zinc phosphating waste liquid, water and sodium silicate, and the environmental safety of recycling of the waste incineration fly ash is remarkably improved. The method is low in cost and easy to operate, only simple equipment is needed, the process is short, the used zinc phosphating waste liquid is industrial waste, waste is treated with waste, and the cost is reduced.
本发明公开了一种垃圾焚烧飞灰的资源化利用方法及其产品和应用，将垃圾焚烧飞灰加入到锌磷化废液中浸泡，固液分离，干燥，得到改性垃圾焚烧飞灰；将改性垃圾焚烧飞灰、水和硅酸钠混合，搅拌，养护，制成飞灰基胶凝材料。本发明通过锌磷化废液清洗垃圾焚烧飞灰实现了重金属的稳定化和氯盐的去除，并通过与水和硅酸钠制备飞灰基胶凝材料的方式对重金属进行了进一步的固化，显著提升了垃圾焚烧飞灰再利用的环境安全性。该方法成本低，操作容易，只需要简单的设备，流程较短，所使用的锌磷化废液是一种工业废弃物，实现了以废治废，降低了成本。
