Reclaimed water pollutant detection system and method

The invention provides a reclaimed water pollutant detection system, which comprises a pollutant database used for storing compound types corresponding to various pollutants in reclaimed water; the pollutant detection subsystem is used for acquiring a reclaimed water to-be-detected sample in the to-be-detected area and detecting the to-be-detected sample; and the characteristic generation subsystem is used for acquiring the distribution characteristics of pollutants in the reclaimed water in the to-be-detected area according to the water distribution coefficients corresponding to the various compounds. According to the method disclosed by the invention, the compounds in the reclaimed water are counted, and effective reference is provided for a subsequent detection process by comparing the types and concentrations of pollutants in the reclaimed water from different sources and with different treatment processes; the retention time of the components of the compounds corresponding to the pollutants is calculated
