The invention discloses an organic waste desorption process, which comprises the following steps of: (1) adsorbing: cooling and filtering organic waste gas, and collecting into an adsorber through a gas collecting system for adsorbing; (2) desorbing: desorbing the organic waste gas through thermal nitrogen gas to obtain desorbed mixed gas; and (3) recovering: recycling the desorbed gas, wherein during adsorption, the temperature of the thermal nitrogen gas is 110-160 DEG C; and the adsorber is a fixed bed adsorber which takes active carbon particles as an adsorbent. Due to the adoption of the process for desorbing, the desorption efficiency is increased, the thermal nitrogen gas desorption efficiency can be up to 98 percent, the problems of steam desorption acid corrosion is solved, and the service life of equipment is greatly prolonged; the water content of a mixed solution is low, so that treatment is not required, the mixed solution can be directly applied to production, and the economic benefit of the recovering system is increased; nitrogen gas desorption is adopted, so that the service life of an adsorption material in a reaction container is prolonged, the production cost is lowered, and manpower and materials are saved; and meanwhile, the problem that solvents which are miscible and slightly soluble in water such as alcohols, ketones, esters and the like cannot be directly recovered through steam desorption is solved. The organic waste gas desorption process is suitable for the industries of printing, light industry, coating, chemistry, electronics and the like.
