Treatment method of sodium tetrachloroaluminate

The invention relates to a treatment method of sodium tetrachloroaluminate. The treatment method is characterized by comprising the following steps: 1) crushing sodium tetrachloroaluminate blocky crystals; 2) adding a certain amount of hot water, and carrying out a reaction at a temperature of 50-100 DEG C, 3) after the reaction is finished, adding an alkali metal hydroxide or sodium bicarbonate to neutralize HCl, and 4) transferring the harmless substance obtained in the step 3) into a wastewater sedimentation tank. The product treated by the treatment method of sodium tetrachloroaluminate isharmless and environmentally friendly. 本发明涉及一种四氯铝酸钠的处理方法，其特征在于，包括下列步骤，1)将四氯铝酸钠块状结晶物破碎；2)加入一定量的热水进行反应温度为50～100℃；3)反应结束后，加入碱金属氢氧化物或碳酸氢钠中和HCl；4)将步骤3中得到的无害物质转入废水沉淀池中。本发明的四氯铝酸钠的处理方法处理后的产物无害、环保。
