摘　　要：介绍了电石法聚氯乙烯、燃煤、再生汞、有色金属采选、硫酸和电池行业的含汞废水来源及治理现状。化学沉淀法和吸附法是我国含汞废水治理的主要技术方法,改进传统化学沉淀法是提高含汞废水治理效率的常用方法。由于原料和生产工艺的不同,不同行业所产生的含汞废水物理化学性质也有很大的差别,企业应根据自身含汞废水的特点,采用几种技术灵活组合的方式进行治理。The source and treatment of mercury-containing wastewater from production of calcium carbide method polyvinyl chloride （PVC） , coal-fired power plants, regenerated mercury enterprises, non-ferrous metal smelting industry, sulfuric acid industry and battery industry are introduced. Treatment process of mercury-containing wastewater is generally chemical precipitation method and adsorption method. Impro- ving the traditional chemical precipitation method is key way to increase mercury removal efficiency. As a result of different raw materials and production processes, mercury-containing wastewater from different in- dustries always have different physical and chemical properties. Enterprises should select a combination of several techniques,according to the actual mercury-containing wastewater.
