On-line monitoring and analysis method of three-dimensional fluorescence spectrum in urban domestic sewage treatment process

1. Three-dimensional fluorescence spectrum data of water samples in each process of sewage treatment were measured by F7000 three-dimensional fluorescence spectrometer in the experiment.2: For the three-dimensional fluorescence spectrum data, the scattering program in MATLAB is used to remove the scattering interference.3. The data after removing the scattering interference are processed by the algorithm (FRI/PCA) to obtain new indicative parameters.
