The invention provides a method and device for treating high-concentration nitrobenzene-containing waste water by using air-stripping-microelectrolysis-fenton oxidation method, belongs to the technical field of high-concentration nitrobenzene-containing waste water treatment, and aims to solve the problems that the fenton method is high in treatment cost and toxic intermediate products are easy to produce to cause secondary pollution, and the nitrobenzene contaminants cannot be mineralized into inorganic small molecular materials through a single micro electrolysis method. According to the method, air-stripping mass transferring between the high-concentration nitrobenzene-containing waste water and the air can be completed in a hypergravity device, after air stripping is finished, the waste water is introduced into a ferric-carbon microelectrolysis tank with a stirring device for microelectrolysis reduction reaction, then hydrogen peroxide is added into the microelectrolysis tank, ferrous ions in the waste water and the hydrogen peroxide form a fenton reagent, hydroxyl free radicals with a high oxidizing property can be generated, and finally organic matters in the waste water can be oxidized and degraded. The process is simple, the function of each technology is maximized, so that the purpose of using waste to treat waste is achieved, the treatment cost is reduced to the largest extent, the treatment efficiency is improved by 20%, the reaction time is shortened by 25%, and the treatment cost is greatly reduced.
