Curing method of manganese slag and anti-seepage method of manganese slag stockpile
The invention belongs to the technical field of environmental protection, and provides a curing method of manganese slag and an anti-seepage method of a manganese slag stack warehouse. According to the curing method provided by the invention, one or more of the mineral powder, the cement clinker, the carbide slag, the metakaolin, the sodium silicate and the coal gangue are used as the modified material to cure and modify the manganese slag, so that ammonia nitrogen and heavy metal elements such as manganese, zinc and copper in the manganese slag can be fixed, and permeation is reduced; meanwhile, the modified material can improve the structural strength of the manganese slag, so that the manganese slag can effectively resist rainwater erosion, argillization in the manganese slag stockpile is avoided, and leakage and dam break accidents possibly occurring in the manganese slag stockpile in the later period are greatly reduced. According to the anti-seepage method for the manganese slag heap reservoir, permeation of heavy metal elements such as ammonia nitrogen, manganese, zinc and copper can be effectively reduced, and the possible leakage and dam break risks of the manganese slag heap reservoir can be greatly reduced.
本发明属于环保技术领域，提供了一种锰渣的固化方法及锰渣堆库的防渗方法。本发明提供的固化方法，以矿粉、水泥熟料、电石渣、偏高岭土、硅酸钠和煤矸石中的一种或多种为改性材料，对锰渣进行固化改性，能够将锰渣中的氨氮及锰、锌、铜等重金属元素固定下来，减少渗透；同时，改性材料能够提高锰渣的结构强度，使其能够有效抵抗雨水侵蚀，避免在锰渣堆库中泥化，极大地降低了后期锰渣堆库可能出现的渗漏及溃坝事件的发生。本发明提供的锰渣堆库的防渗方法，能够有效减少氨氮及锰、锌、铜等重金属元素的渗透，且能够大幅降低锰渣堆库可能出现的渗漏及溃坝风险。
