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。
연산축전지기업생산폐수중함유대량적산폐액、중금속리자，pH정산성。침대해폐수적특성，채용“이급침정+생화+활성탄과려”조합공예진행처리，중금속적배방농도체도《오수종합배방표준》（GB 8978-1996）일급표준。
A great deal of acid waste liquor and heavy metal ions,being acidic,is contained in the wastewater pro-duced 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 con-centration of the heavy metals meets the first class requirements of “Integrated Wastewater Discharge Standard”(GB 8978-1996).
