  • 摘要: 溶解性有机物（DOM）结构、组分复杂，传统水处理工艺（混凝、沉淀、过滤、消毒）、深度处理工艺等对DOM去除有限，在消毒过程中可能生成消毒副产物.DOM的结构、组分影响其在饮用水处理过程中的去除效果.为了深入了解DOM在饮用水处理过程中的结构、形态变化，需采用多种检测方法对其变化进行表征.本文围绕DOM在不同饮用水处理工艺中的分子量、馏分、芳香性及荧光组分等性质的变化，综述了当前饮用水研究较为广泛的预处理分级（物理分级-超滤膜过滤、化学分级-树脂吸附）、紫外-可见吸收光谱、三维荧光光谱等表征方法的研究进展，对不同表征方法的优点及局限性进行了详细探讨，以期为准确评估水处理过程中DOM的变化提供科学依据.
    Abstract: The structure and components of dissolved organic matter (DOM) are complex. Traditional drinking water treatment processes (coagulation, sedimentation, filtration, disinfection) and advanced treatment processes have limited removal of DOM and many generate disinfection by-products during the disinfection process. The structure and composition of DOM influence its removal effect during drinking water treatment. In order to gain a deeper understanding of the structure and morphological changes of DOM during drinking water treatment, various detection methods are needed to characterize the changes. This article focuses on the changes in the molecular weight, fractions, aromaticity and fluorescence components of DOM in different drinking water treatment processes, and summarizes the research progress on the characterization methods for drinking water research, including pretreatment classification (physical grading-Ultrafiltration membrane filtration, chemical fractionation-resin adsorption), ultraviolet-visible absorption spectroscopy, three-dimensional fluorescence spectroscopy, etc. The advantages and limitations of different characterization methods were discussed in detail in order to provide a scientific basis for the accurate assessment of DOM changes during water treatment.
