Method for preparing cementing material from multiple solid wastes
The invention provides a method for preparing a cementing material from multiple solid wastes, and relates to the field of solid waste resource utilization. The specific scheme is as follows: the biomass, the calcium raw material, the aluminum raw material and the red mud are dried and crushed and then uniformly mixed with ferric sulfate to obtain a raw material, and the raw material is subjected to oxygen-limited carbonization at 300-500 DEG C, catalytic decomposition at 1100 DEG C and firing at 1250-1350 DEG C. According to the method, the used solid wastes are wide in source, and high-quality resource utilization of the solid wastes can be realized.
本发明提供了一种多固废制备胶凝材料的方法，涉及固体废弃物资源化利用领域。具体方案为：将生物质、钙质原料、铝质原料、赤泥、经烘干破碎后与硫酸铁混匀得生料，在300~500 oC限氧碳化，在1100 oC催化分解，在1250 oC~1350 oC烧制胶凝材料，本方法所用固体废弃物来源广，可实现固体废弃物的高质资源化利用。
