A shortcut nitrification anaerobic ammonia oxidation reaction device for realizing sequencing batch/continuous flow comprises an aeration unit for providing aeration; the activated sludge reaction unit is arranged at the bottom of the reaction device; mixing water and removing pollutants; the combined filler reaction unit is arranged above the activated sludge reaction unit and is used for reducing sludge loss; the sponge filler reaction unit is arranged above the combined filler reaction unit and is used for realizing denitrification reaction and reducing sludge loss; and the monitoring unitis used for monitoring the water quality DO value and/or the pH value. The operation mode of the reaction device disclosed by the utility model can be mutually switched between a sequencing batch operation mode and a continuous operation mode, so that the operation mode of the reaction device is adjusted according to different sewage quality conditions to achieve a stable and efficient sewage treatment effect; therefore,
