Title: | 活性碳去除消毒副產物生成前質及其生成潛能之模式分析(3/3) | Authors: | 蔣本基 | Issue Date: | 31-Jul-2002 | Publisher: | 臺北市:國立臺灣大學環境工程學研究所 | Abstract: | Since the increasing pollutions from industrials, agricultures and domestic discharge, water suppliers have to employ advanced processes to ensure their water meeting regulations, and further to supply higher quality and more stable water. Granular activated carbon (GAC) adsorption has been widely used on water treatment and wastewater treatment for decades. In spite of the high efficiency for removing pollutants, the regeneration of exhausted GAC will raise the cost and operational problems when using GAC. On the other hand, the biological activated carbon (BAC), which possesses both adsorption and biodegradation properties, has become in focus. Using BAC can reduce the demand of chemical dosages, and can elongate the useful life of GAC beds; however, there are still some problems of BAC to solve. Although some empirical approaches have been reported, no theoretical model has been proposed for BAC columns. Hence, to quantify and differentiate the capacities of adsorption and biodegradation is the major study of BAC. Furthermore, studies of the effects of operational conditions, i.e. hydraulic loading, can improve the performance of BAC for practical application. |
