摘　　要：煤矸石是我国煤炭工业的固体废弃物,对环境和生态平衡造成了极大的危害。阐述了目前煤矸石在我国的综合利用情况,介绍了以煤矸石为原料,用酸浸法从中提取聚合氯化铝、聚氯硅酸铝、聚合硫酸铝3种絮凝剂的工艺路线,对絮凝剂的目前需求状况和应用前景做了深入分析。The gangue is a solid waste in coal industry and has a negative effect on environment and ecological balance. This paper expounds the situation of the comprehensive utilization of the gangue in our country at present, introduces the technical route of extracting three kinds of the coagulant agents including the poly-aluminium chloride, poly-aluminium silicate and poly-aluminium sulphate from the gangue by using the acid leaching method, and makes deep analysis on the current market demand and application prospect of the gangue.
