The ABR reactor is called anaerobic diversion reaction device, which is a high-efficiency energy-saving anaerobic device developed in 1982 by Mccarty in the United states. In 1983, the anaerobic diversion reaction device with the equal width of the upper flow chamber and the lower flow chamber is reformed into a new ABR reactor with the wide upper flow chamber and the narrow lower flow chamber, and a diversion bevel is arranged at the tail end of the baffle plate.

The hydraulic characteristics in each reaction chamber approach a complete mixing, while the overall reactor resembles a plug flow. The wastewater enters the reaction chambers and flows forwards in a baffling way up and down along the guide plate, and then sequentially passes through the sludge bed of each reaction chamber, and organic matters in the wastewater are removed by fully contacting with microorganisms. The sludge in the reaction chamber runs up and down under the flowing action of the waste water, and a large amount of anaerobic sludge is intercepted in the reaction chamber due to the blocking action of the guide plate and the self-sedimentation performance of the sludge. The ABR reactor is widely applied, and the problem of uneven water distribution of the ABR reactor is more and more shown.
