The utility model relates to a reactor for treating industrial wastewater. The lower part of the reactor for treating the industrial wastewater is a granule sludge layer, a three-phase separator is arranged on the upper part of the reactor, a water outlet pipe is arranged on the upper part of the reactor, a water inlet pipe is arranged at the bottom of the reactor, a return pipe is arranged between the water outlet pipe and the water inlet pipe, the water inlet pipe is connected with a water distributor, the water distributor is a radiation type water distributor, and a round table shaped guide cylinder is arranged in the reactor. According to the utility model, a high removal effect of COD (Chemical Oxygen Demand) is realized under a low hydraulic load condition, and the energy consumption and the operating cost are reduced; meanwhile, inflow can be uniformly distributed to the bottom of the whole reactor, so that a uniform ascending velocity is generated, and the treatment effect of the reactor on the waste
