Seawater micro-plastic particle pollutant classification identification instrument and classification identification method

The invention provides a seawater micro-plastic particle pollutant classification identification instrument and a classification identification method, and the seawater micro-plastic particle pollutant classification identification instrument comprises a flowing system, a detection light generation system and an information collection and processing system. The flowing system is used for extracting and detecting micro-plastic particle pollutants in a sea area in real time and comprises a sea water pump and a micro-flow channel which are connected in sequence; the detection light generation system is used for scanning seawater micro-plastic particle pollutants; the information collecting and processing system comprises an optical fiber probe, a spectral grating, a photoelectric detector and a convolutional neural network, and the optical fiber probe collects coherent anti-Stokes Raman scattering signals. The system efficiently collects coherent anti-Stokes Raman scattering signals, performs spectrum broadening
