摘要
以长江陈行水库原水为研究对象,探讨高锰酸钾预氧化-O3/BAC组合工艺对水中有机物、消毒副产物前驱物的去除效果,并评价该工艺出水生物稳定性。结果表明,生物活性炭出水CODMn均值为0.63 mg.L-1,平均去除率68.9%,UV254均值为0.005 cm-1,平均去除率89.0%;高锰酸钾预氧化-O3/BAC组合工艺可以有效去除水中氯化消毒副产物前驱物,对THMFP和HAAFP的去除率分别为66.2%和84.2%;该工艺出水AOC质量浓度为47μg.L-1,,生物稳性较好。
Taking the raw water of Yangtze Chenhang Reservoir as the research object, the organics and DBPs precursors removal efficiency, and biological stability by potassium permanganate pre-oxidation and ozone/biological activated carbon process were investigated. The results showed that the average concentration of CODMn in BAC effluent was 0.63 mg.L-1, the average removal rate was 68.9%, the average removal rate of UV254 can reach 89.0%, average UV254 was 0.005 cm-1; potassium permanganate pre-oxidation and ozone/biological activated carbon process can effectively control the formation of DBPs precursors, the removal rate of THMFP and HAAFP were 66.2% and 84.2%, respectively; the AOC of effluent in this process was 47 μg. L-1.
