A sampling program was conducted to investigate the formation of disinfection by-products (DBPs) and dissolved organic carbon (DOC) at two advanced water treatment plants in Kaohsiung City, Taiwan. The results in this study can be used as a reference for the operational control of water treatment plants and the setting of regulations in Taiwan. Samples of drinking water were collected from two advanced water treatment plants from June 2007 to April 2008. Changes in the concentration of dissolved organic carbon, the trihalomethane formation potential, and the haloacetic acids formation potential were measured in raw water samples. Variations in the concentrations of trihalomethanes (THMs) and haloacetic acids (HAA(5)) in finished drinking water were evaluated. The major species of HAA(5) were in the order of dichloroacetic acid and trichloroacetic acid and the THM was of trichloromethane. DOC was strongly related to DBPs in raw water. In this investigation, the removal efficiency of DBPs in Plant A (ultrafiltration/reverse osmosis system) exceeded that in Plant B (ozonation/biological activated carbon system). Both advanced water treatment plants greatly improved the quality of drinking water.
本研究在台湾高雄市两座进阶水处理厂进行采样，以探讨消毒副产物（DBPs）与溶解性有机碳（DOC）的形成。本研究结果可供台湾地区之水处理厂操作控制与法规订定之参考。自 2007 年 6 月至 2008 年 4 月，本研究分别于两座进阶水处理厂采集饮用水样本。量测原水样本中溶解性有机碳浓度、三卤甲烷生成潜能（THMFP）与卤乙酸生成潜能（HAAFP）的变化，并评估饮用水中三卤甲烷（THMs）与五种卤乙酸（HAA(5)）的浓度变化。HAA(5)的主要成分依序为二氯乙酸及三氯乙酸，而 THM 则为三氯甲烷。DOC 与原水中的 DBPs 有密切关系。在本研究中，厂 A（超滤/反渗透系统）的 DBPs 去除效率优于厂 B（臭氧/生物活性炭系统）。两座进阶水处理厂皆大幅提升饮用水品质。
