Harmless solid waste compound and preparation method thereof
The invention relates to the technical field of environmental protection, in particular to a harmless solid waste compound and a preparation method thereof.The preparation method of the harmless solid waste compound comprises the steps that ardealite, sludge and a curing accelerator are mixed and prepared into slurry, persulfate and a solvent are mixed and prepared into a persulfate solution, and the persulfate solution is added into the slurry; and adding a persulfate solution into the slurry, standing and solidifying, and finally roasting. The method not only realizes innocent treatment of the phosphogypsum so as to greatly improve the mechanical properties and environmental adaptability of the building gypsum prepared from the phosphogypsum, but also realizes cooperative treatment of the sludge and the phosphogypsum so as to achieve the purpose of treating waste with waste.
本发明涉及环境保护技术领域，具体涉及一种无害化固体废料复合物及其制备方法，其中，一种无害化固体废料复合物的制备方法，包括：将磷石膏、污泥和固化促进剂进行混合并制成浆料，将过硫酸盐与溶剂混合配制成过硫酸盐溶液，将过硫酸盐溶液加入浆料进行静置凝固，最后进行焙烧处理即可。本方法不仅实现了磷石膏的无害化处理，从而极大提高磷石膏所制备的建筑石膏的力学性能及环境适应性，同时还实现了污泥和磷石膏的协同处理从而达到以废治废的目的。
