摘　　要：采用气象色谱质谱联用仪(GC/MS)、荧光光谱、紫外光谱等手段,分析了高含盐废水溶解性有机物(DOM)在臭氧氧化过程中的变化特性,验证了臭氧工艺运行效果。结果表明,臭氧工艺对高盐废水DOM中的芳环化合物、酚类、苯胺类、多烯类物质去除效果明显,对酰胺类物质去除效果相对较差;同时,臭氧氧化过程中产生酮酸和酮醛等副产物,致使该工艺对DOM的矿化效能不佳。The variation characteristics of dissolved organic matter(DOM)in high salinity wastewater during ozonation were analyzed by GC/MS,fluorescence spectrum and UV spectrum,and the operation effect of ozone process was verified.The results showed that the removal efficiency of aromatic compounds,phenols,anilines and polyenes in DOM from high salinity wastewater by ozone process was obvious,while the removal efficiency of amides was relatively poor;meanwhile,ketone acids and ketone aldehydes and other by-products were produced in the process of ozonation,which resulted in poor mineralization efficiency of DOM.
