| 摘 要： | 针对臭氧氧化作用对受污染地表水中溶解性有机物去除效果的影响进行研究。结果表明:臭氧投加比低于1mgO3/mgDOC时,臭氧对UVA、CODCr和UV410等有机物去除效率较高;臭氧投加比例为0.7mgO3/mgDOC时,BOD/COD由7.4%提高至18.4%,比紫外消光度(SUVA)逐渐降低并趋于平缓;不同臭氧投加比例下水中溶解性有机物的三维荧光指纹光谱变化规律表明,受污染地表水DOM中主要荧光物质为芳香族蛋白质(荧光峰A、B和C)及类腐殖酸(荧光峰D),其中,A峰、B峰和C峰的中心位置分别位于225/300nm、225/338nm和275/342nm;臭氧投加比例为0.7mgO3/mgDOC时峰强削减率为64%～81%,同时部分芳香族蛋白质的结构也发生了变化。

| Abstract: | This paper studied the effects of ozonation on dissolved organic matter(DOM) in po-lluted surface water.The results showed: if the ozone dosage rate was below 1 mgO3/mgDOC,the removal of ozone on UVA,CODCr,and UV410 were relatively high;if was 0.7 mgO3/mgDOC,the rate of BOD/COD increased from 7.4% to 18.4%,and SUVA decreased gradually and tended towards stability;the dissolved organic three-dimensional fluorescence spectra finger-print variance under different ozone dosage rates showed that fluorescent subs... |
