  • 摘要: 以东江、西江和北江3种原水为研究对象，采用臭氧预处理-常规处理-臭氧活性炭系列处理，研究原水中有机物的去除及臭氧化副产物的产生和转化。结果表明，东江、西江和北江水中CODMn、UV254、甲醛和溴酸盐沿各处理单元过程变化规律基本一致；CODMn总去除率分别为60%、51%和39%，UV254总去除率分别为74%、96%和97%，最终出水甲醛浓度分别为0.004 mg/L、0 mg/L和0 mg/L，BrO3-分别为3.1 μg/L、8.7 μg/L和35.5 μg/L；CODMn的去除主要在预臭氧和活性炭过滤2个处理单元，预臭氧对UV254总去除率贡献最大，甲醛和溴酸盐浓度在主臭氧处理单元达到其峰值（西江甲醛除外）；氨氮和有机物浓度较低、pH值较高的北江原水，出水溴酸盐浓度最高。
    Abstract: The raw waters from Dongjiang River, Xijiang River and Beijiang River were taken as the research objects, and the removal of organic matter and the generation and transformation of ozonation byproducts by preozonation-conventional treatment-O3-GAC combined processes were investigated. The results showed that change laws of CODMn,UV254,formaldehyde and bromate of the three rivers in the processing units were consistent. The total removal rates of CODMn are 60%,51% and 39%, respectively; while those of UV254 are 74%,96% and 97%, respectively. The effluent concentrations of formaldehyde are 0.004 mg/L,0 mg/L and 0 mg/L, respectively; while those of bromate are 3.1 μg/L,8.7 μg/L and 35.5 μg/L, respectively. CODMn are mainly removed in preozonation and GAC units. The influence of preozonation on UV254 removal is relatively great. The peaks of formaldehyde and bromate appear after the post-ozonation unit (except for formaldehyde of Xijiang River). The concentration of bromate in treated water of Beijiang River which has less ammonia nitrogen and organic matter and higher pH value is the highest.
