The invention discloses a resveratrol composite microbial agent for treating high concentration PAHs wastewater and a usage method thereof. The composite microbial agent comprises: a reagent I and a reagent II; the reagent I is: an methylobacterium suspension diluted with an inorganic salt culture medium; the reagent II is: a mixed solution of an inorganic salt and resveratrol; the usage method includes the following steps: step 1. culturing and acclimating methylobacterium; step 2. preparing the methylobacterium suspension; step 3. preparing a resveratrol solution; step 4. uniformly mixing wastewater, the methylobacterium, and the resveratrol solutionin proportion; and step 5. filtering out water; and the microbial agent and the usage method find that resveratrol can significantly promotedegradation of activity of a PAHs key enzyme in an endophytic body, thereby promoting degradation and removal of PAHs in water by endophytes; and the microbial agent and the usage method provide a new method with high effici
