Abstract：The fluorescence fingerprint tracing technology is used to identify pollution sources based on the specificity of EEM,which means that the position and intensity of the fluorescence peak in the EEM vary with the types and concentrations of fluorescent pollutants in sewage.Taking the S Industry Park and Sewage Treatment Plant in D City in the north as the research object,the EEMs of sewage from various enterprises show significant differences,with their own characteristic fluo-rescence peak information.Therefore,the specific fluorescence peaks and intensity thresholds of sewage from various enter-prises were determined.A fluorescence fingerprint database was constructed.Combined with the LabVIEW traceability system,automation of pollution source tracing was achieved.The fluorescence fingerprint tracing technology can solve pollution problems from the source,improve the efficiency of water quality supervision effectively,so it has broad application prospects.
