Harmless environment-friendly electrolytic manganese residue treatment method
The invention discloses a harmless and environment-friendly electrolytic manganese residue treatment method, and relates to the technical field of electrolytic manganese residues, the electrolytic manganese residues are subjected to potassium hydroxide activation and etching agent etching treatment by using a microwave reaction method to obtain the electrolytic manganese residues with a porous structure, and then tetraethoxysilane is used as a silicon source to prepare the electrolytic manganese residues with the porous structure. And nano silicon dioxide is generated in situ in internal pores of the electrolytic manganese residues. The nano silicon dioxide with high mechanical strength serves as a supporting framework of the porous electrolytic manganese residues, the nano silicon dioxide and the porous electrolytic manganese residues form a reinforcing system, the mechanical strength of the electrolytic manganese residues can be improved, and the compressive strength and breaking strength of the concrete are remarkably improved as an additive of the cement concrete. Through harmless environment-friendly treatment on the electrolytic manganese residues, the problem of environmental pollution caused by the electrolytic manganese residues is solved, resource comprehensive utilization is achieved, the green and environment-friendly concepts are met, and meanwhile the practical application of the electrolytic manganese residues in building materials such as concrete is expanded.
本发明公开了一种无害化环保处理电解锰渣的方法，涉及电解锰渣技术领域，利用采用微波反应法，对电解锰渣进行氢氧化钾活化和刻蚀剂刻蚀处理，得到多孔结构的电解锰渣，然后以正硅酸乙酯作为硅源，在电解锰渣的内部孔隙中原位生成纳米二氧化硅。高机械强度的纳米二氧化硅作为多孔电解锰渣的支撑骨架，两者形成增强体系，可以改善电解锰渣的力学强度，作为水泥混凝土的添加剂，显著提高了混凝土的抗压强度和抗折强度。通过对电解锰渣的无害化环保处理，解决了电解锰渣环境污染问题，并且实现了资源化综合利用，符合绿色环保和环保理念，同时拓展了电解锰渣在混凝土等建筑材料中的实际应用。
