Method used for carrying out innocent treatment on hazardous waste electrolytic aluminum ash
The invention discloses a method used for carrying out innocent treatment on hazardous waste electrolytic aluminum ash. The method is characterized by mainly comprising the following steps that firstly, raw material electrolytic aluminum ash is subjected to first-time breaking and screening; secondly, particle aluminum is subjected to melting and ingot casting; thirdly, the particle aluminum is subjected to secondary breaking and screening; and fourthly, the collected fine aluminum ash is subjected to dry method fluorine removal aluminum ash harmless treatment. The treatment method is large intreatment amount, high in fluorine removal efficiency (generally larger than 99%), free of draining fluorine containing waste water, free of secondary pollution and equipment and equipment corrosionand the like, and capital construction cost and running cost are both low.
本发明公开了一种将危险废物电解铝铝灰进行无害化处理的方法，其特征在于：该方法主要包括如下步骤：（1）将原料电解铝铝灰进行第一次破碎筛分；（2）将颗粒铝进行熔化铸锭；（3）将颗粒铝进行第二次破碎筛分；（4）对所收集的细铝灰进行干法除氟铝灰无害化处理，本发明的处理方法处理量大，除氟效率高(一般大于99%)，不排含氟废水，无二次污染和设备腐蚀等问题，基建费用和运行费用都较低。
