电池生产中重金属废水的治理试验研究

摘要

A high - efficiency EWP wastewater purifier was used in the treatment of the heavy metal - containing wastewater from a battery factory. Results of the test showed that after the treatment, the figures of Hg2 + , Mn2 + and Zn2 +in the wastewater were all below the discharge stamdard of Guangzhou City, the outlet water was clear, the cost of the treatment agent was only 0.70 yuan/t which was 60% lower than the cost of only using the method of coagulatory rnsettlement.%采用EWP高效污水净化器处理电池厂重金属废水试验结果表明：废水经治理后Hg2+、Mn2+、Zn2+指标都低于广州市排放标准，出水清澈；处理药剂成本仅为0.70元/t，比单纯的混凝沉淀法低60％。
