| 摘 要： | 为控制矿泉水中的溴酸盐含量,采用活性炭(GAC)技术对矿泉水和超纯水中的溴酸盐进行小试研究,同时根据碘吸附值和其溴酸盐控制能力进行GAC的选型,并进行中试实验,研究GAC对溴酸盐的去除效果。结果表明,当空床接触时间(EBCT)为5min时,矿泉水和超纯水中溴酸盐浓度均降至10μg·L-1以下。12种GAC的碘吸附值不同,GAC1、GAC2、GAC3和GAC4对溴离子和溴酸盐吸附结果显示,GAC1对水中溴离子去除效果最好,可以用于控制溴酸盐的生成;GAC2对水中溴酸盐去除效果最好,可以用于降低生成后溴酸盐含量。中试结果显示,臭氧化过程中生成的过量溴酸盐经GAC吸附,其含量可以降低至5μg·L-1以下。

| Abstract: | In order to control the bromate in mineral water,the batch-scale test of GAC(Granular Activated Carbon,GAC)was applied for the reduction of bromate in mineral and ultrapure water.According to the GAC iodine Absorption value and the capacity of controlling bromate,at the same time,the specific GAC was chosen.And the pilot-scale test was also used to evaluate the removal of bromate by GAC after forming during the ozonation.It was found that when EBCT(Empty Bed Contact Time)was 5min,bromate concentrations of u... |
