摘　　要：本文介绍了采用生物制剂处理某冶炼企业废水以及工厂初期雨水中铊的工艺及应用情况。其针对不同浓度的冶炼废水,在原有废水处理工艺的基础上,采用自主研发的生物制剂进行改进。在控制好反应体系的pH值、药剂投加量、絮凝沉淀等工艺参数后,铊的平均去除率在89.9%以上,出水铊含量可稳定在5μg/L以下。This article introduces the process and application of using biological agents to treat wastewater from a smelting enterprise and thallium in the initial rainwater of the factory.For smelting wastewater with different concentrations,improvements have been made on the basis of the original wastewater treatment process,using self-developed biological agents.After controlling the pH value of the reaction system,dosage of agents,flocculation precipitation and other process parameters,the average removal cost of thallium is over 89.9%,and the thallium content in the effluent can be stabilized at below 5μg/L.
