摘　　要：监测了丰水期和枯水期供水管网中余氯和加氯消毒副产物的变化。结果表明,三氯甲烷和加氯消毒副产物的总体和分段变化趋势相似,经过管网输送后三氯甲烷相对出厂水有所增加;管材、使用时间、输送距离会不同程度影响管网中三氯乙醛的浓度;枯水期加氯消毒副产物在出厂水的基础上也会增加。所建立的关系模型显示,监测点加氯消毒副产物与出厂水加氯消毒副产物、管材和输送距离、监测点余氯之间存在良好的线性关系。The changes of residual chlorine and chlorinated disinfection by-products in water supply pipeline network were monitored during flood season and dry season. The results showed that the trend of the total and sub-sectional changes of the chloroform and chlorine disinfection by-products were not changed much,but the trichloromet hane increased after the transportation. The concentration of the trichloracetic aldehyde in the pipe was influenced by the material and using time of the pipeline,and the transportation distance with different degrees. Rising concentration of chlorine disinfection by-products on the basis of the effluent was observed in dry season. The relationship model established showed that there was a good linear relationship between the chlorine disinfection by-products of the monitoring point and the effluent,the pipe material and the transportation distance and the residual chlorine of the monitoring point.
