摘要:为控制矿泉水中澳酸盐含量,采用改变臭氧浓度的方法,对添加澳离子的矿泉水、超纯水
和自来水分别进行臭氧氧化5min,观察臭氧氧化过程中臭氧、溴离子以及水质对溴酸盐生成的
影响;同时利用向自来水中添加一定浓度溴离子的方法,研究CT值( Ozone Coucentrationxcontact
ime,CT)对溴酸盐生成的影响。结果表明,随着臭氧浓度和溴离子浓度的增加,溴酸盐生成量增
加。当臭氧质量浓度≥0.4mgL,添加相同浓度的澳离子时,矿泉水中生成的澳酸盐量大于自来
水和超纯水中溴酸盐量。矿泉水不同,添加相同浓度的澳离子,生成的溴酸盐量也不同,但当臭氧
质量浓度≥0.4mgL时,溴酸盐量均大于10ugL。CT值增大导致澳酸盐生成量大幅増加。因此
可以通过降低臭氧浓度和溴离子浓度的方法,滅少臭氧消毒中溴酸盐的生成量

Abstract: In order to decrease the bromate content in the mineral water, the effect of ozone
bromide, and water quality on bromate formation were investigated by using the different
oncentration bromide with different ozone concentrations for 5 min to ozonatedthe mineral waters
ultrapure water and drinking water. Meanwhile, drinking waler with certain bromide was applied for
the C T (ozone concentrationxcontact time, CT effect on the bromate formation. It was found thal
with the inerease of ozone and bromideconcentrations the generated bromate increased. When
ozone concentration was =0.4 mg/L, with the same bromide addition, the bromates generated in
mineral water were more than that in ultrapure water and drinking water. At the sarne: time, the
