Abstract:

The combined process,neutralization-coagulation sedimentation-activated carbon adsorption,has been used for treating the lead-containing wastewater from a lead-acid battery producing enterprise. Its effluent COD is less than 50 mg/L,and Pb²⁺ less than 0.9 mg/L,meeting the first class requirements of the Integrated Wastewater Discharge Standard. The process has the advantages of simple process operation,long life cycle,low operating cost,etc.

Key words: wastewater containing lead, coagulation sedimentation, adsorption

摘要：

采用中和-混凝沉淀-活性炭吸附的组合工艺，对铅酸蓄电池生产企业的含铅废水进行处理，出水COD<50 mg/L，Pb²⁺<0.9 mg/L，满足《污水综合排放标准》的一类标准要求，且具有工艺操作简单、设备使用周期长、运行费用低等优点。
