常规净水工艺去除有机物效果的三维荧光光谱分析法

有机物的荧光特性被广泛用来解析其在水体中的来源与分布。荧光光谱技术具有灵敏度高、选择性好、且不破坏样品结构的优点，非常适合用来研究有机物的化学和物理性质。运用三维荧光光谱分析技术对常规净水工艺中有机物的去除效果进行了研究。实验结果表明，三维荧光光谱技术能有效地揭示净水工艺中有机物的变化过程。在整个净水过程中，没有完全消除类富里酸荧光物质，也没有产生新的荧光物质。就类富里酸荧光物质的去除效果而言，混凝沉淀基本没有去除作用，过滤作用的去除率在5%～15%之间。

Study on the Effects of Organic Removal by Traditional Purification Process with Three-Dimensional Excitation Emission Matrix Fluorescence Spectroscopy

Fluorescence spectroscopy is widely used to elucidate the origin and structure of organic matters in water substance.Due to its high sensitivity,good selectivity and nondestructive nature,fluorescence technique is suitable to the study of chemical and physical properties of organic matters.Three-dimensional excitation emission matrix fluorescence spectroscopy(3DEEM) was applied to analyze the effects of organic removal by traditional purification process.The results show that 3DEEM is able to disclosure the changes of organic matters in the treatment processes effectively.Traditional purification process can remove some fulvic-like organic matter,but cannot remove it completely.Coagulant sedimentation basically does not have an effect of fulvic-like organic matter removal.The removal proportion of fulvic-like organic matter through filtration is 5%-15%.
