摘　　要：研究了臭氧/单过硫酸氢钾(O_(3)/PMS)氧化工艺处理Q水厂水源水时溴酸盐的生成规律,同时对比分析了O_(3)/PMS工艺处理纯水、S学校自来水、H泉水、Q水厂水源水、J水库水等不同水质配制的含溴水时溴酸盐的生成情况。结果表明,在O_(3)/PMS处理含溴Q水厂水源水时,当n(PMS)/n(O_(3))(物质的量之比)在0~1.5范围内增大时,PMS对溴酸盐生成的抑制作用呈增强趋势,且当n(PMS)/n(O_(3))=1.5时抑制作用达到最大,继续增大n(PMS)/n(O_(3)),PMS对溴酸盐生成的抑制作用减弱。当O_(3)/PMS处理不同水质的含溴配水时,投加PMS对溴酸盐生成的影响效果不同。O_(3)/PMS处理含溴纯水、H泉水和J水库水配水时,O_(3)和PMS联用会促进溴酸盐的生成;O_(3)/PMS处理含溴S学校自来水和Q水厂水源水配水时,O_(3)和PMS联用会抑制溴酸盐的生成,这主要是因为水中有机物与O_(3)和PMS发生了一系列反应从而影响了溴酸盐的生成。Formation of bromate in source water of Q waterworks treated by ozone/potassium monopersulfate(O_(3)/PMS)oxidation process was investigated,and the formation of bromate in different water containing bromide prepared by pure water,S school tap water,H spring water,source water of Q waterworks,and J reservoir water was compared and analyzed when treated by O_(3)/PMS process.When source water of Q waterworks containing bromide was treated by O_(3)/PMS,the inhibition of PMS on bromate formation showed an increasing trend with the n(PMS)/n(O_(3))(molar ratio)increasing in the range of 0-1.5,and the inhibition was the largest when n(PMS)/n(O_(3))was 1.5.When n(PMS)/n(O_(3))continued to increase,the inhibition of PMS on bromate formation was weakened.The effect of PMS on bromate formation was different when the different water quality containing bromide was treated by O_(3)/PMS.When the pure water,H spring water and J reservoir water containing bromide were treated by O_(3)/PMS,the combination of ozone and PMS promoted the formation of bromate.When O_(3)/PMS was employed to treat S school tap water and source water of Q waterworks containing bromide,the combination of O_(3) and PMS inhibited the formation of bromate.The reason was mainly because of a series of reactions between organic matter in water and O_(3)/PMS affected the formation of bromate.
