Backfill material as well as preparation method and application thereof
The invention belongs to the technical field of solid waste recycling, and particularly relates to a backfill material as well as a preparation method and application thereof. The backfill material provided by the invention comprises humic acid and coal-based solid wastes. The humic acid and the coal-based solid waste are mixed, so that the pH value of the coal-based solid waste can be reduced, the heavy metals in the application environment can be removed, and the method has important practical value for reutilization of the coal-based solid waste and environmental protection.
本发明属于固体废物再利用技术领域，具体涉及一种回填材料及其制备方法和用途。本发明提供的回填材料包括腐殖酸和煤基固废物。本发明通过将腐殖酸与煤基固废物混合，既可以降低煤基固废物的pH，又可以去除所应用环境中的重金属，对煤基固废物再利用、环境保护具有重要实用价值。
