Harmless treatment method for byproduct industrial salt
The invention discloses a harmless treatment method for byproduct industrial salt, and belongs to the technical field of harmless treatment of byproduct industrial salt, and the method comprises the following steps: S1, adding water into byproduct industrial salt, heating and stirring for 1-2 hours, standing, filtering, collecting filtrate, and carrying out suction filtration and evaporation to obtain solid industrial salt; s2, grinding solid industrial salt into powder, adding limestone, clay, slag, coal and mineralizer powder into the industrial salt powder in proportion, mixing and stirring, and obtaining a mixture; s3, performing high-temperature calcination on the mixture to obtain gray solid cement; and S4, crushing the gray solid to obtain a cement finished product. According to the method, the byproduct industrial salt is mixed with the limestone, the clay, the slag, the coal and the mineralizer powder and then subjected to the high-temperature calcination reaction, metal ions in the byproduct industrial salt can be solidified in a cement product, and therefore harmless treatment of the byproduct industrial salt solid waste is achieved, energy conservation and environmental protection are achieved, and environmental pollution is reduced.
本发明公开了一种副产工业盐无害化处理的方法，属于副产工业盐无害化处理技术领域，包括如下步骤：S1：向副产工业盐中加入水，加热搅拌1～2h，静置后过滤，收集滤液，抽滤蒸发，得到固体工业盐；S2：将固体工业盐研磨至粉末状，并在工业盐中粉末中按比例加入石灰石、黏土、矿渣、煤和矿化剂粉末，混合搅拌，得到混合料；S3：将混合料进行高温煅烧，得到灰色固体水泥；S4：将灰色固体进行粉碎，得到水泥成品。本发明通过将副产工业盐与石灰石、黏土、矿渣、煤和矿化剂粉末混合后进行高温煅烧反应，能够将副产工业盐中的金属离子固化在水泥产品中，从而实现副产工业盐固废的无害化处理，节能环保，减少了环境污染。
