Harmless treatment method of manganese slag
The invention relates to the field of industrial waste residue treatment, in particular to a harmless treatment method for manganese residues. The harmless treatment method of the manganese slag comprises the steps of manganese slag filter pressing, manganese slag pretreatment and curing treatment, the manganese slag pretreatment is achieved by adding a manganese curing agent, an ammonia nitrogen curing agent and an alkali activator into the manganese slag, and the dosage of the manganese slag is 89%-94.9%, the dosage of the manganese curing agent is 4%-6.5%, the dosage of the ammonia nitrogen curing agent is 1%-3.5%, and the dosage of the alkali activator is 0.1%-1%; the manganese curing agent is prepared from the following components in parts by weight: 10-15 parts of high-silicon aluminum solid waste, 0.5-5 parts of graphene nanosheets and 2-5 parts of CaO, and the ammonia nitrogen curing agent is 6-14 parts by weight of anhydrous phosphogypsum. According to the harmless treatment method for the manganese slag, the curing efficiency is high, the compressive strength of a cured body is high, the damage of harmful substances in the manganese slag to the environment is reduced, the high-silicon-aluminum solid waste is recycled, and the method is green and environmentally friendly.
本发明涉及工业废渣处理领域，具体是一种锰渣的无害化处理方法。该锰渣的无害化处理方法包括压滤锰渣、锰渣预处理和固化处理，锰渣预处理通过在锰渣中添加锰固化剂、氨氮固化剂、碱激发剂实现，锰渣、锰固化剂、氨氮固化剂、碱激发剂用量分别为：锰渣89％～94.9％，锰固化剂4％～6.5％、氨氮固化剂1％～3.5％，碱激发剂0.1％～1％；所述锰固化剂由以下重量份组分组成：10～15份高硅铝固废、0.5～5份石墨烯纳米片、2～5份CaO，氨氮固化剂为无水磷石膏按重量份计为6～14。本发明提出的锰渣无害化处理方法的固化效率高，固化体抗压强度大，降低锰渣中有害物质对环境的损害，资源化利用高硅铝固废，绿色环保。
