The invention discloses a resourceful treatment method of gallic acid production waste water and belongs to the field of waste water treatment. The method comprises steps of solid phase extraction and stripping for regeneration, wherein in the solid phase extraction step, a high-molecular polymer which contains a monomer with a benzene ring structure and has a basic group is used as a solid phase extracting agent to extract and enrich production waste water; in the step of stripping for regeneration, a stripping agent containing a reductive protective agent is used for eluting the extracted solid phase extracting agent, and an obtained stripping regeneration liquid can be recycled. According to the method, a solid phase extraction manner is adopted, the defect of secondary pollution caused by extraction with an organic reagent is effectively avoided, the difficulty in follow-up treatment of waste water is reduced, gallic acid and tannin are effectively recycled, waste water treatment and resource recycling are combined, and integration of environmental benefits, social benefits and economic benefits is realized.
