摘　　要：采用臭氧/生物活性炭工艺(O3/BAC)对密云水库水进行深度处理中试研究,试验结果表明:臭氧/生物活性炭工艺的处理效果优于单独活性炭工艺(GAC),在最佳臭氧投加量(2.0mg/L)下,O3/BAC对CODMn、UV254、BDOC的去除率分别比GAC工艺的高9.9%、30.5%、12.9%;同时,活性炭的结构特征对于生物降解作用有重要影响,破碎炭对BDOC的去除效果明显优于柱状炭的。The O3/BAC process was applied in the pilot-scale advanced treatment of Miyun Reservoir water. The experimental results show that the treatment efficiency of O3/BAC is better than that of GAC alone. When the optimal ozone dosage is 2.0 mg/L, the removal efficiencies of CODM., UV254 and BDOC by O3/BAC are 9.9%, 30.5% and 12.9% respectively higher than those by GAC alone. Meanwhile, the structural feature of activated carbon has a great effect on biodegradation. The removal efficiency of BDOC by crushed carbon is significantly better than that of cylindrical carbon.
