根据沿海地区水源水的特点，对高咸水经过纳滤和超滤膜处理后，研究了其在管网中余氯衰减以及产生的消毒副产物卤乙酸的生成规律。用荧光光谱分析了超滤膜处理后的水、纳滤膜处理后的水以及杭州地区自来水的水质特点。并在此基础上研究了超滤膜处理后的水、纳滤膜处理后的水以及自来水在管网系统中余氯衰减和卤乙酸生成规律。试验结果发现，自来水中的余氯衰减最快。并且随着温度的升高，管网中三种不同水质的余氯值都会随着温度的升高而快速衰减，管网中卤乙酸的生成量也会随之增加。

Based on the characteristics of source water in coastal district, this paper investigates residual chlorine decay and haloacetic acids (HAAs) formation of halite water desalinated by nanofiltration membrane and ultrafiltration membrane in the pilot-scale water distribution systems. The nature organic matter (NOM) of ultrafiltration water, nanofiltration water and tap water were analyzed by 3D fluorescence spectroscopy. The residual chlorine decay and HAAs formation of three different waters in pilot-scale water distribution systems under different temperatures were compared. The results show the residual chlorine decay coefficient of tap water is the fastest. And with the increasing of temperature, the amount of HAAs formation increased.
