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

摘要： 铅酸蓄电池企业生产废水中含有大量的酸废液、重金属离子，pH呈酸性。针对该废水的特性，采用“二级沉淀+生化+活性炭过滤”组合工艺进行处理，重金属的排放浓度达到《污水综合排放标准》（GB 8978-1996）一级标准。
