英文摘要： With the social progress and the speeding up of industrialization, the water pollution is still severe. The water quality detection and analysis technique need to be improved. For the advantages including high sensitivity, good selectivity, quick and easy operation,etc.3-D fluorescence spectrum analysis technology have been increasingly widely used in environmental monitoring, water treatment and other fields. Rapid detection and analysis of water quality are of great significance to identification of pollutants, judgment of pollution source and the early warning. Based on fluorescence analysis technology, the project studies a small, fast, sensitive three-dimensional fluorescence spectra measurement system of various fluorescence substances with a wide range of excitation and emission wavelength scanning; Combined with chemometrics methods such as parallel factor analysis and multi-dimensional partial least squares, the project develop data processing and analysis software platform of three dimensional fluorescence spectrum that integrated fluorescence spectra measurement and data analysis, improve the ability to analyze complex multi-component system, achieve the qualitative identification and quantitative analysis of multiple organic pollutants in water. The measurement systems and software platforms could meet the detection needs of various industries to water quality pollution such as petroleum in water, organic matter in water, phytoplankton pigments, pesticide residues, provide a new means of detection and technical support for department of public health and environmental protection, and has broad application prospect in the water quality organic matter monitoring of drinking water and sewage treatment process.
