摘　　要：以西南某水厂进水为原水,采用净水工艺中常见的液氯、氯胺考察对不同季节原水的处理效果、消毒副产物及需氯量进行了实验分析,取得了实验数据。实验结果表明:氯胺同液氯相比可以减少致癌副产物氯仿的产生,降低加氯量,提高灭菌消毒效果,并且在气温较高的春夏季节,有效氯消耗量大于气温较低的秋冬季节,这可能是与原水中含有的较多的有机物有关。In this paper, the influencing factors, disinfection by-products and chlorine content of raw water in different seasons were analyzed by liquid chlorine and chloramine, which were common in the water treatment process of water in the southwest of China.The experimental data were obtained.The The results showed that chloramine could reduce the production of carcinogenic byproduct chloroform, decrease the amount of chlorine and improve the sterilization and disinfection effect, and the effective chlorine consumption was higher than that of the lower temperature in the spring and summer season Autumn and winter season, which may be related to the raw water contains more organic matter.
