Collaborative curing treatment method for electrolytic manganese slag and red mud
The invention provides a collaborative curing treatment method for electrolytic manganese slag and red mud. According to the method, quick lime, red mud and red mud leachate are adopted as raw materials to effectively cure and stabilize the electrolytic manganese slag, soluble alkali in the red mud exists in water in the form of OH-, reacts with manganese ions to generate precipitate, and reacts with ammonia nitrogen (NH3-N) to generate ammonia gas, and thus pollutants in the electrolytic manganese slag can be effectively removed. On one hand, the red mud leachate plays a role of a solvent, onthe other hand, alkaline substances in the red mud leachate play a role of reactants, thus the reaction rate is increased, and the treatment cost is reduced. The red mud and the red mud leachate areused, so that the use amount of the quick lime is effectively reduced, and the treatment cost is further reduced. According to the method, a step-by-step reaction means is adopted, the reaction efficiency is effectively improved, and the curing rate of manganese ions in the electrolytic manganese slag reaches 93.7% or above.
本发明提供一种电解锰渣与赤泥的协同固化处理的方法，所述方法采用生石灰以及赤泥和赤泥渗滤液为原料对电解锰渣进行有效的固化、稳定，赤泥中的可溶性碱在水中以OH‑的形式存在，与锰离子反应，生成沉淀，与氨氮(NH3‑N)反应生成氨气，达到对电解锰渣中污染物的有效去除；赤泥渗滤液一方面发挥溶剂的作用，另一方面其中的碱性物质发挥反应物的作用，加快反应速率，降低处理成本；赤泥与赤泥渗滤液的使用，有效降低了生石灰的用量，进一步降低处理的成本。本发明提供的方法采用分步反应的手段，有效提高反应效率，对电解锰渣中锰离子的固化率达到93.7％以上。
