Based on a high-concentration liquid spectrum direct measurement method, the invention aims at obtaining high absorbance and high sensitivity, and provides a high-concentration-difference optical-path-adjustable high-sensitivity absorbance liquid rapid transmission and distribution system which comprises a photosensitive adjusting module, a PLC control module, a liquid transmission and distribution module and a cleaning and air-drying module. According to the requirements that different species and concentrations are matched with different optical paths, and the different optical paths are matched with different transmission and distribution parameters, the optimal optical path in the photosensitive adjusting module is automatically matched by utilizing absorbance and sensitivity which are continuously and dynamically obtained by a serial optical path, a signal is fed back to the PLC control module in real time, and the transmission and distribution parameters of inlet and outlet liquid of a target optical path are adjusted in real time; interference noise caused by turbulent bubbles is not generated, second-level switching among different optical paths and second-level replacement of liquid samples in the same optical path are achieved through photosensitive adjustment, PLC control and closed-loop control among liquid transmission and distribution, and a foundation is laid for second-level real-time monitoring of pollutants in a high-concentration solution.
