Electrolysis and Volatilization of Bromide from Drinking Water to Minimize Bromate Production by Ozonation 电解和挥发饮用水中的溴化物 以减少臭氧氧化产生的溴酸盐
发布日期: 2007-11-01
本powerpoint演示文稿的目的是确定电解和挥发是否是一种有效的方法 降低废水浓度的有效技术 加利福尼亚州项目用水中的溴化物导致 臭氧氧化时减少溴酸盐的生成。提出的假设是 溴可以电解成溴和溴 可在低pH(<3.5)和空气吹脱下挥发 使用精细气体,以较低的成本生产成品水 溴浓度和形成的可能性较小 臭氧氧化时使用溴酸盐。列出了去除溴化物的原因,以及目前的溴化物处理方法。电解和挥发的概述包括:电解和水解;电解反应器;分析技术;实验1- 溴化物去除受 流量和电流;实验2- 深度脱溴;实验3- 电解和臭氧氧化,A、B和C。总体结论如下: 溴化物的氧化和挥发 降低饮用水中溴的浓度 水域; 臭氧氧化前去除水中的溴化物 可以减少溴酸盐的形成 正确的条件;和 Cl2的DPD-FAS滴定技术 似乎适合电解水。包括表格、数字。
The objective of this powerpoint presentation was to determine if electrolysis and volatilization can be an effective technique for reducing the concentration of bromide in California State Project Water resulting in reduced formation of bromate when ozonated. The hypothesis presented is that bromide can be electrolyzed to bromine and bromine can be volatilized at low pH (<3.5) and air stripping with fine gas, producing a finished water with a lower bromide concentration and less potential to form bromate when ozonated. Reasons for removing bromide are listed, along with current bromide treatments. An overview of electrolysis and volatilization is provided that includes: electrolysis and hydrolysis; electrolysis reactor; analytical techniques; Experiment 1 - Bromide Removal as Impacted by Flow and Current; Experiment 2 - Bromide Removal by Depth; and, Experiment 3 - Electrolysis and Ozonation, A, B and C. Overall conclusions were that: the oxidation and volatilization of bromide does lower the concentration of bromide in drinking waters; removing bromide from water prior to ozonation can reduce the formation of bromate under the right conditions; and, the DPD-FAS titration technique for Cl2 does appear to be adequate for electrolyzed waters. Includes tables, figures.
