Comprehensive utilization method of industrial solid waste-high salinity wastewater
The invention belongs to the technical field of industrial solid waste-wastewater resourceful treatment, and particularly relates to a comprehensive utilization method of industrial solid waste-high salinity wastewater. Raw materials of the cementing material comprise industrial solid waste and high-salinity wastewater, the mass ratio of the high-salinity wastewater to the industrial solid waste is (30-70): 1, and the preparation method of the cementing material comprises the following steps: evaporating and concentrating the high-salinity wastewater, adding the industrial solid waste, uniformly mixing to obtain cementing material slurry, pouring the cementing material slurry into a mold, and curing to obtain the cementing material. According to the method, the problems of environmental pollution caused by solid waste storage and high cost required by high-salinity wastewater treatment can be solved, sodium chloride in the high-salinity wastewater can be subjected to high-value recycling, the sodium chloride which does not participate in the reaction is leached out by soaking the cementing material, and the sodium chloride is concentrated and returned to the PVC industry for electrolytic hydrogen production; and the material can consolidate harmful elements in solid waste and waste water, and harmful substances cannot be leached even in maritime work application occasions.
本发明属于工业固体废弃物‑废水资源化处理的技术领域，具体涉及一种工业固废‑高盐废水综合利用方法。所述胶凝材料的原料包括工业固废和高盐废水，所述高盐废水和工业固废的质量比为30‑70:1，其制备方法是先将高盐废水蒸发浓缩，加入工业固废混合均匀，得胶凝材料浆液，再倒入模具进行养护得胶凝材料。本发明不仅可以解决固废存放造成的环境污染和高盐废水处理所需的高成本问题，还可以将高盐废水中的氯化钠进行高值回用，通过浸泡胶凝材料将未参加反应的氯化钠浸出，浓缩返回PVC行业进行电解制氢使用，且该材料可以固结“固废和废水”中的危害元素，即便是在海工应用的场合也不会有危害物的浸出。
