摘　　要：通过分析某水厂水处理过程各阶段水样中的三氯甲烷生成情况,讨论常规水处理对三氯甲烷生成的影响,并结合该厂的生产实际,提出水处理过程中降低三氯甲烷生成的建议:一是优化前加氯投加方式,选择合适的加氯点;二是提高原水浊度的去除率,减少消毒副产物的前驱物质。In this article, through analyzing the formation of trichloromethane in different stages of a waterworks＇ water treatment, the conventional water treatment effects on the formation of trichloromethane was discussed. Taking into account the actual situation of the waterworks＇ production, two suggestions were proposed for reducing the formation of trichloromethane one was optimizing the pre-treatment chlorine adding methed and selected a suitable point for chlorine adding; and the other one was improving the efficiency of purifying source water to reduce the compounds that contributed to the formation of via products from disinfection.
