【摘要】 考察了催化臭氧氧化联用对滤后水中有机物的去除效果,结果表明,臭氧氧化与O₃/CeO₂联用可以有效降低滤后水UV₂₅₄和DOC。臭氧氧化和O₃/FeOOH联用去除有机物的效果不及臭氧氧化与O₃/CeO₂联用。对催化臭氧氧化联用后的有机物进行EEM分析,臭氧氧化与O₃/CeO₂联用后A型荧光基团浓度快速降低,发生蓝移后的C型荧光基团变化很小;臭氧氧化与O₃/FeOOH联用后A型荧光基团和C型荧光基团的浓度同时降低。更多还原

【Abstract】 The experiments were carried out to investigate the removal effect of organic matter in filtered water by the different combined processes of ozonation and catalytic ozonation.The results showed that the combination of ozonation and ozonation catalyzed by CeO₂ decreased UV₂₅₄ and DOC effectively in the filtered water.The removal of organic matter by the combination of ozonation and ozonation catalyzed by FeOOH was not as good as the combination of ozonation and ozonation catalyzed by CeO₂.The organic matters were analyzed by the fluorescence excitation-emission matrix after the combined process.The concentration of fluorophores of type A decreased greatly and the concentration of fluorophores of type C which appeared blue shift were not evident after the combination of ozonation and ozonation catalyzed by CeO₂;the concentration of fluorophores of type A and type C decrease simultaneously after the combination of ozonation and ozonation catalyzed by FeOOH.更多还原
