摘要
采用去离子水的模拟配水试验,研究了酒石酸、丙烯酸、苯胺等3种不同结构的有机物存在时臭氧消毒过程中甲醛的生成情况以及对溴酸盐生成的影响。结果表明,含双键结构的丙烯酸被臭氧氧化后产生的甲醛量最大,而饱和直链结构的酒石酸和含苯环结构的苯胺则几乎不产生甲醛;当有机物相对于Br-浓度很高时,Br-的存在对这3种有机物的臭氧氧化没有明显的影响;水中丙烯酸和苯胺的存在对溴酸盐的产生有抑制作用,而酒石酸的存在对溴酸盐的产生却有促进的作用。
Simulation studies in deionized water were conducted to investigate the variances of the formation of formaldehyde during the process of ozonation with the existing of three kinds of organic matters with different function groups,tartaric acid,crylic acid and aniline.And the influences of the three kinds of organic matters made on the bromate formation during the ozonation process were analyzed.The experimental results indicated that,crylic acid with double bond structure produced the most formaldehyde after the oxidation by ozone,while tartaric acid with saturated straight-chain and aniline with aromatic ring produced no formaldehyde.When the concentration of the organic matters was far more than Br-,the existing of Br-had no influence on the oxidation of the organic matters by ozone.The existing of crylic acid and aniline inhibited the formation of bromate,while the existing of tartaric acid enhanced its formation.
