Abstract

The invention relates to the field of purification processes of flocculants, in particular to an efficient purification process of a flocculant, which comprises the following steps: preheating a reaction tank, arranging a primary sedimentation tank and a secondary sedimentation tank, and adding quantitative polyacrylamide into the secondary sedimentation tank to remove impurities in a polyaluminum chloride solution; meanwhile, a spray heater is additionally arranged between the liquid storage pool and the rotary dryer, tail gas of the rotary dryer is collected and then introduced into the spray heater to preheat the polyaluminum chloride removal solution, filter residues in the generation process are subjected to secondary filter pressing, and filtrate and the tail gas are collected and returned to the reaction pool to be recycled. Therefore, the high purity and low energy consumption of the flocculant polyaluminum chloride drying product are achieved.
