Thermal desorption repair prediction method and system for soil polluted by polycyclic aromatic hydrocarbon

The invention discloses a thermal desorption repair prediction method and system for soil polluted by polycyclic aromatic hydrocarbons, and the method comprises the steps: building a relation between soil-gas distribution coefficients and temperature changes of different types of polycyclic aromatic hydrocarbons according to an early-stage basic experiment, and obtaining a polycyclic aromatic hydrocarbon temperature sensitivity coefficient list; analyzing the type of polycyclic aromatic hydrocarbon in the soil sample, querying a chemical manual to obtain the octanol-gas distribution coefficient of the polycyclic aromatic hydrocarbon, and querying a temperature sensitivity coefficient list according to the type of the polycyclic aromatic hydrocarbon obtained through detection and analysis to obtain the temperature sensitivity coefficient of the corresponding polycyclic aromatic hydrocarbon. Analyzing and detecting the organic carbon content and the soil particle density in the soil sample; calculating a first
