Summary:The invention relates to a formula and a process for producing polymeric aluminum chloride. 5 tons of running water are added into a reaction tank and 14.2 tons of 31 percent hydrochloric acid are added into the reaction tank at the same time, and stirring is started for uniformly mixing; steam heating is started, 4.25 tons of bauxite are put at the same time, the timing is started when the temperature reaches 95 DEG C, and the reaction time is 40 to 60 minutes; after the reaction completes, the temperature is kept above 75 DEG C, 5 tons of calcium aluminum powder are put when 8 tons of running water are added, and the temperature is kept above 95 DEG C after the addition of the running water and the calcium aluminum powder completes for reaction for 2 hours; after the reaction completes, 5 tons of running water are added, and after the aluminum oxide content is adjusted to 10.0 percent, the mixture in the reaction tank is transferred to a sedimentation tank to allow large sludge particles to settle; after th
