摘　　要：对二苯基氯化膦生产过程中产生的四氯铝酸钠进行了综合处理,使用甲醇将氯化钠和三氯化铝进行解离,回收后的氯化钠可直接用于解络合反应,得到的三氯化铝用于制备絮凝剂PAC,其水处理效果达到了外购PAC的处理效果。The sodium tetrachloroaluminate produced in the producing process of chlorodiphenyl phosphine（CDPP）was treated. Sodium chloride and aluminium chloride were separated using methanol. The recovered sodium chloride could be used directly in the decomplexing reaction. The recovered aluminium chloride was used to prepare polyaluminium chloride（PAC） with the same efficiency as the purchased PAC in water treatment.
