摘　　要：介绍了电石法氯乙烯生产中含汞废水的来源,以及对废水的处理过程。根据环保标准的更新,对系统进行了升级改造,保障了排水满足《烧碱、聚氯乙烯工业污染物排放标准》。由于废水中含有氯乙烯,在排放过程中造成挥发性有机物的扩散,后期对废水中挥发性有机物进行了回收利用。The source of mercury removal wastewater in the production of vinyl chloride by calcium carbide method and the treatment process of the wastewater were introduced.According to the update of environmental protection standards,the system was upgraded to ensure that the drainage met the discharge standards of pollutants for caustic soda and PVC industry.Because the waste water contains vinyl chloride,it causes the diffusion of volatile organic compounds in the process of discharge,and the volatile organic compounds in the waste water are recycled in the later stage.
