Zusammenfassung: | The invention relates to the technical field of aluminum ash recycling, and particularly discloses an aluminum ash treatment method. According to the aluminum ash treatment method provided by the invention, at least one of specific agents such as aluminum salt, ferric salt, calcium salt, weak acid and strong acid is mixed and reacted with the secondary aluminum ash, and the reaction conditions are controlled, so that AlN and F in the secondary aluminum ash are subjected to chemical reaction, the reactivity and leaching toxicity of the secondary aluminum ash are eliminated, and the secondary aluminum ash treatment effect is improved. And a high-aluminum material product with a high additional value is obtained.
本发明涉及铝灰回收利用技术领域,具体公开了一种铝灰处理方法。本发明提供的铝灰处理方法,通过采用特定的药剂,如铝盐、铁盐、钙盐、弱酸、强酸中的至少一种,与二次铝灰混合反应,并通过对反应条件的控制,使二次铝灰中的AlN、F-发生化学反应,从而消除了二次铝灰的反应性和浸出毒性,获得了高附加值的高铝料产品。 |
