摘　　要：为了考察催化臭氧氧化对水中天然有机物的氧化效果,以FeOOH、MgO和CeO2为催化剂,考察了不同催化剂催化臭氧氧化滤后水中有机物的变化情况。结果表明:单独臭氧氧化可以明显地降低滤后水的UV254,但对滤后水的DOC降低并不明显,O3/FeOOH可以明显地提高对滤后水DOC的去除效果;O3与O3/CeO2联用可以有效地提高滤后水UV254和DOC的去除。单独臭氧氧化与臭氧催化氧化联用或是不同催化性质的催化剂之间的联用技术将是今后臭氧深度处理的发展方向。In order to investigate the effects of NOM by catalytic ozonation,FeOOH,MgO and CeO2 were used as catalysts to enhance the ozonation of natural organic matter in the filtered water.The results showed that the UV254 value of the filtered water was reduced significantly by the ozonation with ozone alone,but the variation of DOC value was not obvious.O3/FeOOH could improve the removal of the DOC.Although cerium oxide behaves poor catalytic oxidation efficiency of NOM,the use of cerium oxide in catalytic ozonation after ozone alone could significantly increase the removal of the UV254 and DOC.So,ozone alone combined with the catalytic oxidations would be the development direction of advanced ozonation processes.
