摘　　要：控制管网中消毒副产物生成是研究热点,对管网消毒副产物变化规律进行研究,可为控制管网消毒副产物提供指导。在管网中,余氯、季节变化和管材是影响管网消毒副产物的重要因素,余氯量越大,THMs和HAAs的量就越多;季节变化主要会影响化学作用和微生物活性,消毒副产物的生成速率随温度的升高而显著加快,夏秋生成的消毒副产物更多,春冬生成的消毒副产物相对少一些;铁管的腐蚀能使消毒副产物增加,但产生的Fe2+也能使部分消毒副产物被还原。HAAs与AOC前体物间具有相似性,含量呈正相关性,存在较好的线形关系。The control of disinfection by-products of drinking water distribution systems is a hotspot. The research on regulation of disinfection by-products made by drinking water distribution systems provides guidance for the control of disinfection by-products. Chlorine, seasons and the material pipe in drinking water distribution systems are three main factors that affect the pipe network＇s disinfection by-products. The greater the amount of residual chlorine, the more trihalomethanes and haloacetic acid generate. Changing season will mainly affect the chemical and microbial activity. Formation rate of disinfection by-product becomes high with temperature increasing. Disinfection by-products generate more in summer and autumn and less in spring and winter. Disinfection by-products are increased by iron pipe corrosion, but also reduced by Fe2 ＋produced by iron pipe corrosion. The precursors of haloacetic acids and AOC are similar, which have a good linear relationship.
