The invention relates to a method for treating high-concentration ink wastewater by utilizing a microbial enhanced MBR (Membrane Biological Reactor) process. The method is characterized by comprising the steps of: (1) uniformly mixing garcinia brevibacterium AS1.1204, bacillus licheniformis AS1.518, bacillus megatherium AS1.223, edible-oil pseudomonas AS1.1641 and pseudomonas aeruginosa AS1.512 according to the proportion into compound bacterial solution; (2) preparing nutrient solution; (3) mixing the compound bacterial solution and the nutrient solution and forming mixed liquid; (4) continuously conveying the ink wastewater into a hydrolysis tank added with the mixed liquid, standing for 10-22 hours, and then continuously conveying the obtained mixture to an aerobiotic tank added with the mixed liquid, standing for 12-60 hours; and (5) after aerobiotic treatment, enabling the wastewater to pass through a hollow-fiber microfiltration membrane component, and then continuously discharging the wastewater. The method has the advantages that the ink wastewater can be treated by the used compound bacterial solution with high-efficiency advantage under the high-chloride condition with the salt content being less than or equal to 40000mg/L, the removal rate is up to 95%, and the problems of low degradation rate, serious secondary pollution and instable operation in the traditional biochemical method and physicochemical method for treating the ink wastewater are solved.
