Abstract: A great deal of acid waste liquor and heavy metal ions,being acidic,is contained in the wastewater produced from lead storage battery enterprises. According to the characteristics of the wastewater,the combined process secondary precipitation+biochemistry+activated carbon filtration has been used for its treatment. The discharge concentration of the heavy metals meets the first class requirements of "Integrated Wastewater Discharge Standard" (GB 8978-1996).

Key words: wastewater from storage battery production, heavy metal, secondary precipitation, activated carbon filtration
