Phosphogypsum treating agent, phosphogypsum treating method, preparation method of phosphogypsum filling material and phosphogypsum filling material
The invention relates to a phosphogypsum treating agent, a phosphogypsum treating method, a phosphogypsum filling material preparation method and a phosphogypsum filling material. The treating agent comprises the following components in percentage by mass: 27.7%-96.7% of calcined phosphate tailings, 0.3%-1% of ammonium sulfate, 3%-68% of solid waste micro powder and 0-3.5% of an alkaline activator, wherein the calcined phosphate tailings are calcined products of high-magnesium phosphate tailings. Based on the phosphogypsum treating agent, harmless treatment of phosphogypsum can be achieved, effective utilization of solid waste high-magnesium phosphate tailings can be achieved, and meanwhile the strength requirement of phosphogypsum serving as an engineering filling material is met.
本发明涉及一种磷石膏处理剂、磷石膏处理方法、磷石膏填充材料制备方法以及磷石膏填充材料，处理剂包括以下质量百分比的组分：煅烧磷尾矿27.7％～96.7％，硫酸铵0.3％～1％，固废微粉3％～68％，碱性激活剂0～3.5％，煅烧磷尾矿为高镁磷尾矿的煅烧产物。基于本发明的磷石膏处理剂，既可实现磷石膏无害化处理，又可实现固废高镁磷尾矿的有效利用，同时保证磷石膏作为工程填充材料时的强度需求。
