这项实验室规模的研究调查了空床接触时间（EBCT）和水的影响 生物活性炭（BAC）中卤乙酸（HAAs）去除的温度 柱。EBCT和水温显著影响BAC柱中HAA的去除。 提高EBCT和水温可提高HAA的去除率。在4摄氏度时，平均 在5分钟的EBCT下，六种HAA的去除效率为28%。通过将EBCT增加到 10、15和20分钟后，平均去除率分别提高到55%、69%和89%， 分别地在10℃时，六种HAA的平均去除率分别为65%、94%、98%和99% EBCT分别为5、10、15和20分钟。当温度上升到20摄氏度和30摄氏度时， 即使EBCT时间为5分钟，BAC柱中的HAAs也几乎完全清除 获得。进一步增加EBCT对去除HAA几乎没有好处。HAA的动力学模型 还探讨了在不同EBCT和温度下的去除。包括11个参考文献、表格、图表。

This laboratory scale study investigated effects of empty bed contact time (EBCT) and water temperature on the removal of haloacetic acids (HAAs) in biologically active carbon (BAC) columns. EBCT and water temperature significantly affected the HAA removal in BAC columns. Increasing EBCT and water temperature increased the HAA removal. At 4C, the average removal efficiency for six HAAs was 28% at an EBCT of 5 minutes. By increasing the EBCT to 10, 15, and 20 minutes, the average removal efficiencies increased to 55%, 69%, and 89%, respectively. At 10C, the average removal of six HAAs was 65%, 94%, 98%, and 99% for EBCTs of 5, 10, 15, and 20 minutes, respectively. When temperature increased to 20 and 30C, a nearly complete removal of HAAs in BAC columns even with an EBCT of 5 minutes was obtained. Further increasing EBCT had little benefit on HAA removal. Kinetic models on HAA removal at various EBCTs and temperatures were also explored. Includes 11 references, tables, figures.
