Abstract: Based on the research status of moving bed biofilm reactor ( MBBR) ,the characteristics andreaction mechanisms of the anammox process were discussed. The effects of matrix concentrations,or-ganic matter,temperature,dissolved oxygen and other factors on the stability of the process were ana-lyzed. The application of MBBR was prospected with engineering cases. The analysis showed that a lowconcentration of COD and an appropriate NH+4 -N/NO-2 -N ratio were conducive to the anammoxprocess. It was necessary to maintain the activity of low-temperature anaerobic ammonia oxidation bac-teria( AAOB) in the practical application. Precise control of DO and the fluidization state of the fillercould promote the enrichment of AAOB on the MBBR biofilm,which promoted the stable denitrificationeffect of anammox process. Close-
