Harmless treatment method for comprehensive utilization of ammonium sulfate generated in metal electrolysis process
The invention discloses a harmless treatment method for comprehensive utilization of ammonium sulfate generated in the metal electrolysis process, and particularly relates to the technical field of ammonium sulfate harmless treatment. The method comprises the following steps: respectively carrying out crushing treatment on ammonium sulfate and slaked lime generated in the metal electrolysis process; fully and uniformly mixing the crushed ammonium sulfate and slaked lime in proportion, adding water or filtrate, carrying out mechanical stirring reaction at normal temperature and normal pressure, and collecting ammonia gas obtained by the reaction while reacting to obtain gypsum slurry; after the reaction is finished, inputting the obtained gypsum slurry into a filter press for filter pressing treatment, and continuously collecting ammonia gas obtained by filter pressing in the filter pressing process to obtain gypsum slag; performing low-temperature drying treatment on the obtained gypsum slag to obtain initial gypsum slag; and returning the filtrate to the step 2 for reuse or using the filtrate as a Zhongxing liquid for reuse. The treatment method is simple, the used raw materials are low in cost and can be directly treated in an electrolysis factory, waste discharge is reduced, the environment is protected, and the side benefits of the factory are increased.
本发明公开了一种电解金属过程中产生的硫酸铵综合利用的无害化处理方法，具体涉及硫酸铵无害化处理技术领域。所述方法包括对电解金属过程中产生的硫酸铵和熟石灰分别进行粉碎处理；再将粉碎后的硫酸铵和熟石灰按比例充分混合均匀后，加水或滤液，常温常压下进行机械搅拌反应，边反应边收集反应得到的氨气，得石膏浆；反应结束后，将得到的石膏浆输入压滤器中进行压滤处理，压滤过程中继续收集压滤出来的氨气，得石膏渣；将得到的石膏渣进行低温烘干处理，得到初始石膏渣；滤液返回步骤二再次使用或作为中兴液再利用。本发明的处理方法简单，使用的原料低廉，可以在电解工厂直接处理，减少了废弃物的排放，保护了环境，还增加了工厂的副收益。
