The invention discloses a method for judging the adsorption affinity of granular active carbon to organic pollution components, which comprises the following steps: washing the granular active carbon with ultrapure water, boiling for multiple times, drying to constant weight, putting into a constant-temperature oscillation box to adsorb organic pollutants in water to reach adsorption equilibrium, and measuring the three-dimensional fluorescence spectrum of the adsorbed organic pollutants; using data analysis software to select a specific analysis toolkit to perform parallel factor analysis on the fluorescence spectrum data, determining the component type and the fluorescence intensity of the organic pollutant, and calculating the fluorescence intensity ratio between the components of the organic matter before and after adsorption; and finally, judging the adsorption affinity of the granular active carbon to different components in the organic pollutants. According to the method, the problem that DOC and UV254
