铝矿粉与副产盐酸生产的聚合氯化铝中重金属杂质和有机杂质往往较多，借鉴铁碳微电解原理，人为投加活性炭，创造铝碳微电解条件，用来去除聚合氯化铝中的重金属和有机杂质。在采用铝碳比1：1，动态操作，停留时间在1小时的控制参数，处理费用约6.67元/吨的条件下，原液铅Pb2+含量23.3ppm，处理后铅Pb2+含量下降到5.8ppm，低于国标10ppm的要求。

The polyaluminum chloride produced by bauxite powder and by-product hydrochloric acid has many heavy metals and organic impurities. Referring to the principles of Fe-C micro-electrolysis, by artificially adding activated carbon and creating AL-C micro-electrolysis condition, the heavy metals and organic impurities of polyaluminum chloride can be removed. Under the condition of using the aluminum carbon ratio 1:1, the dynamic operation, the control parameters with the residence time at 1 hour, and the treatment costs about 6.67 yuan/ton, Pb2+content of polyaluminum chloride decreased from 23.3ppm to 5.8ppm, which is below the GB 10ppm requirements.
