Method for preparing filling body by modifying ardealite through biochar and carbide slag
The invention discloses a method for preparing a filling body by modifying ardealite through biochar and carbide slag, and belongs to the technical field of ecological environment protection and solid waste recycling. The preparation method comprises the following steps: pre-soaking charcoal obtained by pyrolysis; drying, grinding and sieving the carbide slag and the ardealite to obtain carbide slag powder and ardealite powder; and fully mixing and stirring the saturated charcoal, the carbide slag powder, the ardealite powder and the cement according to a certain proportion to obtain the modified ardealite filling body. The biochar, the carbide slag and the ardealite can be converted into the cheap modified ardealite filling body with good water resistance, mechanical strength and low leaching, and large-scale consumption and resource utilization of bulk solid wastes of the carbide slag and the ardealite are realized. Compared with the prior art, the method is low in cost, simple to operate and lower in fluorine ion leaching concentration, can meet the requirements of mining area backfilling engineering, realizes recycling, harmlessness and reduction of the carbide slag and the ardealite, achieves the goal of pollution reduction, carbon reduction and synergistic interaction, and generates better economic benefits, social benefits and environmental benefits.
本发明公开一种生物炭协同电石渣改性磷石膏制备充填体的方法，属于生态环境保护和固废资源化技术领域。本发明将通过热解得到的生物炭进行预浸泡；将电石渣和磷石膏烘干研磨过筛，得到电石渣粉和磷石膏粉；将饱和生物炭、电石渣粉、磷石膏粉和水泥以一定比例充分混合搅拌，得到改性磷石膏充填体。本发明能将生物炭、电石渣和磷石膏转化为具有良好耐水性、机械强度和低浸出的廉价改性磷石膏充填体，实现电石渣和磷石膏大宗固废的规模化消纳和资源化利用。与现有技术相比，本发明成本低，操作简单，氟离子浸出浓度较低，可满足矿区回填工程要求，使电石渣和磷石膏资源化、无害化、减量化，达到减污降碳协同增效的目标，产生较好的经济效益、社会效益和环境效益。
