【 摘 要 】

Organic matter (OM) in drinking water treatment is a commonimpediment responsible for increased coagulant and disinfectant dosages,formation of carcinogenic disinfection-by products, and microbial re-growthin distribution system. The inherent heterogeneity of OM implies theutilization of advanced analytical techniques for its characterization andassessment of removal efficiency. Here, the application of simplefluorescence excitation-emission technique to OM characterization indrinking water treatment is presented. The fluorescence data of raw andclarified water was obtained from 16 drinking water treatment works. Thereduction in fulvic-like fluorescence was found to significantly correlatewith OM removal measured with total organic carbon (TOC). Fluorescenceproperties, fulvic- and tryptophan-like regions, were found to discriminateOM fractions of different removal efficiencies.The results obtained in the study show that fluorescence spectroscopyprovides a rapid and accurate characterization and quantification of OMfractions and indication of their treatability in conventional watertreatment.
