The invention discloses an activated carbon adsorption process in the technical field of waste gas adsorption. The process comprises the following steps: 1) waste gas pretreatment, 2) waste gas adsorption, 3) nitrogen desorption and 4) condensation and recovery of an organic solvent. Activated carbon is desorbed and regenerated by introducing nitrogen with high flow rate and high temperature intothe activated carbon, the high flow rate of nitrogen has greater impact on adsorbate molecules, an adsorbate is brought out of the activated carbon conveniently, and by means of high temperature of nitrogen, kinetic energy of the adsorbate is increased, and the adsorbate is separated from the activated carbon conveniently. The desorption and regeneration method can be used for desorption of any type of solvents, and the defect that solvents with high water solubility and high boiling point cannot be desorbed in a water vapor desorption mode is overcome; the waste gas is adsorbed by a pluralityof unconstrained activate
