description The invention discloses a resourceful treatment method and system for float sludge of a sewage treatment plant, and belongs to the technical field of resourceful treatment of the float sludge of the sewage treatment plant. The resource treatment method for the float sludge of the sewage treatment plant comprises the following steps: fermenting the float sludge collected in a biochemical pool or a secondary sedimentation pool of the sewage treatment plant, and then returning fermentation liquor which is maturely fermented into the biochemical pool so as to supplement the COD (Chemical Oxygen Demand) concentration of inlet water of the biochemical pool. As the floating sludge of the sewage treatment plant is high in organic matter content, the floating sludge is intensively collected and then subjected to anaerobic fermentation, and fermentation liquor is used as a carbon source of the sewage treatment plant and supplements part of anaerobic bacteria to a biochemical system, so that the water inlet carbon sourc
