| 摘 要： | 研究空气吹脱塔对饮用水中三卤甲烷的去除效果.在水温为24℃、气温为25℃、水力负荷≤20 m~3/(m~2·h)、气液比60的条件下,THMs去除率可达90%以上.THMs单体中,三氯甲烷最易去除,三溴甲烷最难去除.通过成本分析,吹脱塔运行费用为0.03元/m~3.研究表明,吹脱法是一种费用低、操作简单、高效率的去除THMs的工艺.

| Abstract: | This study investigated the effectiveness of using a packed column to remove trihalomethanes(THMs)in drinking water.The results showed that when water temperature was 24℃,atmosphere temperature 25℃,the hydraulic load 20 m~2/(m~2·h)or lower,air/liquid ratio 60,the percent removal of THMs could generally exceed 90%.Chloroform was the easiest THMs to remove while bromoform was the most difficult.Through the economic calculations,the operation cost was 0.03YUAN/m~3.Air stripping operation was a simple,highly efficient,and cost-effective THMs removing process. |
