The utility model relates to a reactor, in particular discloses a co-metabolism reactor for the high-efficiency treatment of organic matter difficult to degrade in papermaking waste water. The co-metabolism reactor is rectangular, and an external dimension ratio of length to width to height is 2 to 1 to 1; an inner cavity is divided into seven sections, and a volumetric ratio of a water distribution section to an anaerobic section to a primary facultative section to a primary aerobic section to a secondary facultative section to a secondary aerobic section to a settling section in the reaction sections is 1 to 5 to 4 to 3 to 4 to 3 to 2; the anaerobic section of the reactor adopts an equal-resistance radial multipoint uniform water-distribution mode, and a honeycomb duct and an overflow weir which are vertically staggered are arranged on the wall of the water distribution section of the reactor. The co-metabolism reactor can process the organic matter difficult to degrade in the papermaking waste water with h
