Abstract: Anaerobic ammonium oxidation（Anammox） is a novel and cost-effective technology with high nitrogen removal capacity. However，the sensitivity to environmental conditions， and the vulnerability to many pollutants limit the applications of Anammox process. The process enhancement could be an effective measurement to solve these problems. This paper investigated the enrichment of Anammox（including the acceleration of granulation，adding the carrier for formation of integrated biofilm-granule system，the equipment of membrane biological reactor，etc.），the addition of chemical substances（such as manganese dioxide，the graphene oxide，iron ion，the intermediate of Anammox etc.），the application of physical field （including ultrasonic，magnetic field，electric field and so on） as well as bio-augmentation and sequential biocatalyst addition. This paper also analyzed the main technical focuses，explained the mechanisms，and compared the potential of different methods along with the deficiency. It was pointed out that certain aspects，such as the parameters optimization，the combination of different enhancement methods，and the long-term effects as well as the in-depth study of the mechanism，still need to be further investigated.
