A method for regenerating granular activated carbon by arc initiation and discharge includes steps of the granular activated carbon continuously flowing through a heating passage, and applying a DC (direct current) to two electrode plates in the heating passage. Under a combined action of conductive Joule heating and arc heat release, the activated carbon heats up rapidly and an adsorbate is pyrolyzed by high temperature, thereby achieving regeneration. Moreover, a device for regenerating granular activated carbon by arc initiation and discharge includes a feeding device, a heating passage, an aggregate device and an adjustable DC power supply. Two ends of the heating passage are connected with the feeding device and the aggregate device respectively; two electrode plates are provided within the heating passage; the two electrode plates are connected with an output positive pole and an output negative pole of the DC power supply respectively.
