In order to provide technical support for the clean production of lead-acid battery recycling industry,this study investigated the effects of current density,voltage and flow rate on the single-unit selective electrodialysis process of a lead-acid battery recycling plant in northern China.Under the conditions of voltage of 5 V,current density of 20 mA/cm2,influent flow rate of 150 L/h and operation time of electrodialysis unit of 48 min,the H+transmittance in the recovery chamber could reach 80％,and the unit price selective electrodialysis had a higher transmittance to H+.At the same time,univalent selective electrodialysis maintained a low leakage rate for metal ions,with Pb2+leakage rate of 0.6％,Zn2+leakage rate of 2.8％,and Cd2+leakage rate of 1.8％.In this study,the objective of selective separation of H+from heavy metal ions in waste acid disassembly of lead-acid batteries was achieved.
