摘　　要：荧光分光光度法测量简便,灵敏度高,已越来越多地用于化学分析。将工业废水为主的城市污水作为研究对象,分析其荧光指纹特征。该城市污水的三维荧光光谱上有分别位于激发波长/发射波长为275/310,230/340和220/310nm附近的3个荧光峰,未显示出以生活污水为主的城市污水所具有的典型的类蛋白质荧光的特点。该污水荧光强度较高,且工作日和休息日差异大,这可能主要与工业污水含量较大有关。荧光指纹在反映废水组成方面直观、迅速,可以作为水质监测与预警的新方法。The present paper studied fluorescence fingerprint properties of the municipal wastewater with industrial wastewater as major components. There existed three typical fluorescence peaks in the excitation-emission matrix of the municipal wastewater, locating at about λex/λem of 275/310, 230/340 and 220/310 nm respectively. The wastewater didn＇t display typical protein-like fluorescence as the municipal wastewater with domestic sewage as major component. The fluorescence intensity of the wastewater was quite high with remarkable difference between workday and weekend. These might relate to the high content of industrial wastewater. The advantages of the fluorescence fingerprint such as easy and fast measurement and rich information about the components of wastewater make it a novel tool in water quality monitoring and early-warning.
