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 Chenhang reservoir in Changjiang River as the research object, the removal efficiency of precursors of organics and disinfection by-products in the pre-oxidation of potassium permanganate-O3 / BAC was discussed, and the biological stability of effluent was evaluated. The results showed that the mean CODMn effluent concentration of bio-activated carbon was 0.63 mg.L-1, the average removal rate was 68.9%, the average UV254 value was 0.005 cm-1 and the average removal rate was 89.0%. The combination of potassium permanganate pre-oxidation and O3 / BAC could be effective Removal of chlorinated disinfection by-products precursors in water, the removal rate of THMFP and HAAFP were 66.2% and 84.2% respectively; the AOC concentration of the effluent was 47μg.L-1, and the biological stability was better.
