采用XAD-8树脂对臭氧氧化前后炼厂反渗透(RO)浓水中的有机物进行组分分离，并采用紫外分光光度法(UV)、傅里叶红外光谱(FT-IR)、三维荧光光谱(3D-EEM)等方法对不同组分的结构进行表征。结果表明，RO浓水中含有大量的富里酸类腐殖质和腐殖酸类腐殖质等荧光物质；原水溶解性有机物(DOC)含量为(46.1±0.5) mg?L-1，其中疏水酸性有机物(HoA)、疏水碱性有机物(HoB)、疏水中性有机物(HoN)及亲水性物质(HiM)四种组分的比例分别为20.8%、4.5%、27.3%及47.5%。臭氧氧化后各组分比例分别为21.5%、2.6%、15.1%及60.6%，亲水性物质增加了13.1%，但DOC去除率仅为2.5%；HoA和HoN中大量含有C=C、C=O等不饱和键和芳香结构物质，而HiM中含量很少，但含有大量含C-O键及脂肪烃类物质；臭氧氧化可以降低RO浓水中有机物的芳香性构化程度，破坏其中难以被降解的不饱和键，使疏水性物质大量被氧化成亲水性物质。

Before and after ozone oxidation, the dissolved organics (DOM) in reverse osmosis (RO) concentrates from oil refining were separatively separated by XAD-8 resins and characterized by ultraviolet spectrophotometry (UV254), fourier infrared spectroscopy (FT-IR) and three dimensional fluorescence spectroscopy (3D-EEM). The results show that humic-like and fulvic-like substances are found in the RO concentrates. Before ozone oxidation, the original dissolved organics (DOC) has a concentration of ( 46.1 ± 0.5) mg?L-1, which can be classified as drainage water acidic organics (HoA, 20.8%), hydrophobic basic organics (HoB, 4.5%), hydrophobic neutral organics (HoN, 27.3%) and hydrophilic substances (HiM, 47.5%). The concentrations of HoA、HoB、HoN and HiM become 21.5%、2.6%、15.1% and 60.6%, respectively after ozonation, while the concentration of hydrophilic substances increases by 13.1%. However, The DO removal ratio is about 2.5%. C=C, C=O and other unsaturated bond exist in HoA and HoN , and there are more C-O and aliphatic hydrocarbons in HiM. Aromatic structures and unsaturated bonds can be destroyed by ozonation treatment and a large number of hydrophobic substances are transformed into hydrophilic substances.
