description The invention discloses a method for operating anaerobic ammonia oxidation by using a microbial immobilized membrane bioreactor, which comprises an aeration tank, a primary sedimentation tank, a biological treatment tank and a secondary sedimentation tank, wastewater needing to be treated is input from the aeration tank, and treated water is output from the secondary sedimentation tank. The biological treatment tank comprises a first-stage bioreactor, a second-stage bioreactor and a third-stage bioreactor, the first-stage bioreactor, the second-stage bioreactor and the third-stage bioreactor are communicated with one another, and the input end of each bioreactor is communicated with the first-stage sedimentation tank. According to the method, the microorganism immobilization membrane is used for removing nitrogen, the microorganism immobilization membrane can be repeatedly used, no extra energy consumption is consumed, the stability performance is good, the biological reaction can be well carried out, and the
