In 1983, the anaerobic diversion reactor with equal width of the upper flow chamber and the lower flow chamber is reformed into a novel ABR reactor with wide upper flow chamber and narrow lower flow chamber, and a diversion bevel is arranged at the tail end of the baffle plate. The anaerobic diversion reaction device is characterized in that a plurality of layers of partition plates are arranged in the reactor along the water flow direction, the reactor is divided into a plurality of reaction chambers which are connected in series, and each reaction chamber is a unit which firstly flows upwards and then flows downwards and is similar to an anaerobic sludge bed. 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. ABR reactors are widely used, with a doubling of trials prior to engineering applications.
