NOVELTY - The device comprises a raw water tank connected with a synchronous denitrification sludge fermentation coupling denitrification reactor through a water pump. The synchronous autotrophic denitrification synchronous sludge fermentation coupling denitrification reactor is connected with a short range nitrifying reactor through the water pump. A grid room is connected with the short range nitrifying reactor through a partition board having 4-9 cells. Each cell is provided with an aeration device. The short-range nitrifying reactor is connected with a sedimentation tank via a sludge reflux pump.    USE - The device is useful for processing sewage (claimed).    ADVANTAGE - The device has high ammonia nitrogen valid load impact resistance, improves the waste water removal efficiency, and reduces sludge yield.
