中文摘要 | 本研究利用連續式管柱試驗,搭配四種典型臭氧副產物做為目標去除污染物,區分並定量生物活性碳上吸附與生物降解之量;並探討空床接觸時間對上述兩種機制之影響。由分別定量吸附及生物降解之結果顯示,生物活性碳上吸附對生物降解之比例,會因增加空床接觸時間而增加,此結果並暗示吸附平衡對於生物活性碳整體表現而言具有較深遠之影響。 |
英文摘要 | This research was focused on differentiating the adsorption and biodegradation quantities of a biological activated carbon (BAC) column, and on evaluating the effect of empty bed contact time (EBCT) on the performance of the two mechanisms simultaneously for the removal of dissolved organic matter from water. The performance of adsorption and biodegradation on the BAC column was studied using continuous columns tests, and four typical ozonation by-products were selected as the target compounds. The results show that EBCT could influence the performance of both adsorption and biodegradation in extent. Increasing EBCTs could make the equilibrium more complete for adsorption, thereby improving the performance. The ratio of adsorption to biodegradation on the BAC column increased as EBCT increased, and this implied that adsorption was dominant in an equilibrium condition. |
