Tailing surface layer consolidation material based on lysinibacillus sphaericus and application thereof
The invention belongs to the technical field of environmental protection, and particularly relates to a tailing surface layer consolidation material based on lysinibacillus sphaericus. The material comprises the following components in percentage by mass: 15-50% of metal tailing sand, 3-15% of lysinibacillus sphaericus bacterial liquid, 1-10% of urea, 3-15% of anhydrous chloride, 1-6% of potassiumalginate and the balance of water. The preparation method comprises the following steps: respectively crushing the weighed metal tailing sand, urea, anhydrous chloride and potassium alginate, sievingwith a 100-150-mesh sieve, mixing, adding the lysinibacillus sphaericus bacterial liquid and water, and uniformly mixing to obtain the tailing surface layer consolidation material. The using method comprises the steps that the tailing surface layer consolidation material is sprayed to the surface layer of the tailing pond, and 200 L of the tailing surface layer consolidation material is sprayed to the surface of every 500 m < 2 > of the tailing pond. The tailing surface layer consolidation material provided by the invention can form a stable consolidation layer on the surface layer of the tailing pond to achieve a good dust suppression effect, and the material is convenient to obtain, environment-friendly, simple in use method and low in cost.
本发明属于环境保护技术领域，具体涉及一种基于球形赖氨酸芽孢杆菌的尾矿表层固结材料，包括按质量百分含量计的如下组分：金属尾矿砂15％‑50％、球形赖氨酸芽孢杆菌菌液3％‑15％、尿素1％‑10％、无水氯化物3％‑15％、海藻酸钾1％‑6％、余量水；其制备方法为：将称取的金属尾矿砂、尿素、无水氯化物、海藻酸钾分别粉碎过100‑150目的筛目，然后混合，再加入球形赖氨酸芽孢杆菌菌液和水混合均匀，制得所述尾矿表层固结材料；其使用方法为：将所述尾矿表层固结材料喷施至尾矿库表层，且每500m2尾矿库表面喷施200L所述尾矿表层固结材料。本发明提供的尾矿表层固结材料可以在尾矿库表层形成稳定的固化层起到良好的抑尘效果，且物料取材方便、环保，使用方法简单，成本低。
