【摘要】 针对模拟水样中的腐植酸,采用静态实验对比的方法,分析了单独臭氧氧化和活性炭催化臭氧氧化去除腐植酸的效果。实验结果表明:臭氧氧化和活性炭催化臭氧氧化均可去除水中的腐植酸,且后者的去除效果更佳。在水样pH为中性、反应时间为30m in的条件下,活性炭催化臭氧氧化对腐植酸和COD的去除率分别为64.9%和40.8%,比单独臭氧氧化的处理效果分别高出34.2%和26.1%。臭氧氧化和活性炭催化臭氧氧化反应均受水样pH的影响,碱性条件时,腐植酸去除效果最好,中性条件时次之,酸性条件时最差。更多还原

【Abstract】 Comparing the results of static experiments,the removal effects of humic acids in simulated water sample by single ozonation process and activated carbon catalytic ozonation process were analyzed.The experimental results show that both of the two processes can remove humic acids from water and the removal effect by the latter process is better.Under the conditions of neutral pH of the water sample and reaction time 30 min,the removal rates of humic acids and COD by activated carbon catalytic ozonation process are 64.9% and 40.8%,which are 34.2% and 26.1% more than those by single ozonation process,respectively.Both of the two reactions are influenced by water sample pH. The order of pH conditions for humic acids removal effects from the best to the worst is alkaline condition,neutral condition,acidic condition.更多还原
