摘　　要：三卤甲烷(THMs)和卤乙酸(HAAs)是给水厂中具有代表性的消毒副产物(DBPs),如果水厂中消毒副产物生成量过高,将会影响到管网中水质安全。通过比较水厂2种不同处理工艺中各单元出水口的三卤甲烷、卤乙酸浓度变化,分析了消毒副产物DBPs浓度变化情况,讨论比较2套处理工艺水质处理效果。结果表明,水体经过折板反应池—斜板沉淀池—移动冲洗罩滤池处理后,出厂水中消毒副产物量的增加量相对水体经过机械搅拌澄清池—双阀滤池—处理后较小。Trihalides and haloacetic acids are representative disinfection by - products （DBPs） in Water Supply Plant. If the amounts of disinfection by - products are too high in waterworks, it will affect the water security in pipe network. By comparing and THMs and HAAs from two different treatments, the DBPs concentration changes were anglysed, the two sets of process water treatment effect were compared. The results showed that the increase of disinfection by-products of water treated by the process of folding reaction pool-inclined plate sedimentation tank-mobile rinse hood filter is lower than that of water trea- ted by the process of mechanical stirring clarifiers-Dual Valve Filter.
