Treatment method and device for adsorbing lithium battery recovery waste gas by using activated carbon

The invention discloses a treatment method and device for adsorbing lithium battery recovery waste gas through activated carbon, and the treatment method comprises the following steps: introducing waste gas into an activated carbon adsorption device, and adsorbing the waste gas through the activated carbon; discharging the waste gas adsorbed by the activated carbon into a concentration monitoring device, and detecting the concentration of the waste gas; judging whether a preset standard is reached or not according to the result of detecting the concentration of the waste gas, and re-introducing the waste gas into the closed container for adsorption under the condition that the preset standard is not reached; the activated carbon is circularly conveyed between the activated carbon adsorption device and the regeneration device, the activated carbon saturated in adsorption is conveyed into the regeneration device for electrochemical regeneration, and the regenerated activated carbon is conveyed back to the activ
