Water pollution tracing method based on genetic algorithm and three-dimensional fluorescence spectrum recognition

The invention provides a water pollution source tracing method based on genetic algorithm and three-dimensional fluorescence spectrum recognition, which comprises the following steps: carrying out gridding division on a water area to be detected, and setting a water sample collection point on each grid; determining a pollution source calculation point for the polluted water sample by adopting a genetic algorithm; the method comprises the following steps: sampling sewage of associated enterprises in a to-be-detected water area to obtain pollution source water samples; and collecting three-dimensional fluorescence spectrum data of the pollution source water sample by using a fluorescence spectrometer, and constructing a pollution source water sample three-dimensional fluorescence spectrum database. And collecting the three-dimensional fluorescence spectrum of the polluted water sample by using a fluorescence spectrometer, and comparing the three-dimensional fluorescence spectrum of the polluted water sample wit
