Recycling process for waste activated carbon generated in acetaminophen refining working section

The present invention discloses a recycling process for waste activated carbon generated in an acetaminophen refining working section. The process comprises the following steps: a preprocessing process using the waste activated carbon generated in the acetaminophen refining section for high-concentration organic wastewater generated in acetaminophen production, and a waste activated carbon regeneration treatment process on the waste activated carbon filtered in step (1), thereby obtaining finished activated carbon, wherein the methylene blue decolorizing capacity is 17ml/0.1g or above, the yield is improved to be 40%, and the activation rate is shortened within 15s. According to the process disclosed by the present invention, in the combination with the characteristics of the waste activated carbon and wastewater generated in acetaminophen production, the activated carbon is enabled to be mostly used, so that objectives of turning waste into treasure and recycling are achieved; and the effects of reducing the
