Method for co-processing steel slag and desulfurized fly ash

The invention discloses a method for co-processing steel slag and desulfurized fly ash, which comprises the following steps: mixing steel slag as an oxidant and a catalyst with semi-dry desulfurized fly ash, and carrying out hydrothermal reaction, aging and solid-liquid separation. According to the method, the problem that CaSO3 in the desulfurized fly ash and f-CaO in the steel slag are unstable can be solved at the same time, the CaSO3 and the f-CaO are converted into stable substances, and the basic components of the treated product are calcium, silicon, magnesium, aluminum and the like, do not need to be separated and can be recycled together. According to the method, resource utilization of two kinds of industrial solid waste difficult to treat is achieved at the same time, cost is low, the process is simple, and the method has important significance on environment and sustainable development. 本发明公开了一种协同处理钢渣、脱硫灰的方法，将钢渣作为氧化剂和催化剂，与半干法脱硫灰混合后，经过水热反应、陈化、固液分离，即可。本发明可同时解决脱硫灰中CaSO3和钢渣中f-CaO不稳定的问题，使其转化为稳定物质，处理后的产
