摘　　要：以南水北调引江原水为研究对象,比较常规工艺下单独加氯、紫外线加单点加氯、紫外线加两点加氯3种消毒方式的处理效果差别。中试实验结果表明,紫外线加两点加氯消毒对控制消毒副产物三卤甲烷的生成作用明显高于单独加氯消毒和紫外线加单点氯消毒。3种不同消毒方式对引江水均有较好的灭菌效果。与单独加氯消毒相比,滤后水经紫外消毒环节的细菌总数有较大幅度下降。在实际生产中,推荐采用紫外线加两点加氯联合消毒技术。Different disinfection methods were studied to treat Yangtze River raw water from south-to-north water transferproject.The effects of single chlorination disinfection,UV and single point chlorination disinfection,UV and two-pointchlorination disinfection were compared.The results showed that the formation of THMs by UV and two-point chlorinationdisinfection was significantly lower than that by single chlorination disinfection and UV and single point chlorination disinfection.All of the three disinfection methods have good sterilization effect.Compared with single chlorination disinfection,the total number of?bacteria has decreased greatly after UV disinfection.In actual production,the UV and two-pointchlorination combined disinfection method was recommended.
