description The invention discloses a decentralized sewage low-carbon treatment device and method based on anaerobic ammonia oxidation, the device comprises a sewage inlet tank for receiving external raw water, and the sewage inlet tank can respectively convey the raw water into a UASB reactor and a continuous flow reactor in proportion; the UASB reactor is used for converting organic matters in raw water into methane; a suspended anaerobic ammonium oxidation bacterium filler is added into a continuous flow reactor, raw water denitrification is realized through short-cut nitrification/anaerobic ammonium oxidation and short-cut denitrification/anaerobic ammonium oxidation, the hydraulic retention time of an anoxic zone is prolonged to realize synchronous in-situ fermentation of sludge, and a check door is arranged to solve the problem of sludge backmixing; and the secondary sedimentation tank is used for precipitating the denitrified raw water and returning part of sludge to the continuous flow reactor.
