Zusammenfassung:	The invention relates to a saturated activated carbon regeneration treatment device and method for absorbing VOCs gas. According to the method, a supercritical fluid extraction regeneration method isadopted, CO2 becomes supercritical fluid and is in contact with saturated activated carbon by adjusting the temperature and the pressure intensity so that the saturated activated carbon is regenerated, and finally, desorbed organic substances and solvents are absorbed by diesel oil and can be recycled as fuel. The device comprises a CO2 storage bottle, a switch valve, a flow meter, a multifunctional reaction desorption box, a reaction plate, a pressure reducing valve, a water suction pump, a multifunctional separation box, an organic matter recovery box, a steam flushing water tank and an electric heating plate. The device integrates activated carbon regeneration and VOCs recovery, is free of secondary pollution, simple in structure, convenient to operate, low in energy consumption, high in activated carbon regene
