这项研究表明，在35.6华氏度（2摄氏度）下处理的成品水中的三卤甲烷（THM）浓度明显低于在71.6华氏度（22摄氏度）下处理的水中的三卤甲烷（THM）浓度。在金属离子盐混凝过程中，水温似乎不影响总有机碳（TOC）的去除，但在低温下颜色去除略有降低。当水在pH值为5而不是pH值为7时，无论温度如何，混凝去除TOC、颜色和THM生成潜力的效率都会提高。研究发现，在35.6华氏度时，去除低分子量有机物比在71.6华氏度时更困难。获得的数据表明，冬季成品水中THM浓度的降低严格来说是THM形成速率降低的函数。包括15个参考文献、表格和图表。

This study showed that the trihalomethane (THM) concentration in finished water that had been treated at 35.6 degrees F (2 degrees C) was significantly lower than in water treated at 71.6 degrees F (22 degrees C). Water temperature did not appear to affect the removal of total organic carbon (TOC) during coagulation with metal ion salts, but color removal was slightly reduced at low temperatures. The efficiency of coagulation for removing TOC, color, and THM formation potential improved when the water was treated at pH 5 rather than pH 7, regardless of temperature. Removal of low-molecular-weight organic substances was found to be more difficult at 35.6 degrees F than at 71.6 degrees F. The data obtained suggest that reduced THM concentrations in finished water during winter are strictly a function of the reduced rate of THM formation. Includes 15 references, tables, figures.
