Abstract: The sludge from denitrification tank of sewage treatment plant was used for the start-up of anaerobic ammonia oxidation, and the changes of nitrogen and microbial community structure during the start-up process were investigated. The results showed that the anaerobic ammonia oxidation reaction began in only 44 d under the conditions of continuous water inlet and outlet at 32 °C, pH=7.6 and dissolved oxygen < 0.2 mg·L -1 . The start-up of anaerobic ammonium oxidation went through three stages: sludge adaptation period, activity improvement period and stable operation period. The sludge gradually changed from black flocculent sludge during inoculation to reddish-brown granular sludge, and the particle size of granular sludge was mainly distributed in 0.6 – 0 mm. The removal rates of NH4+-N , NO2--N and TN could reach 99%, 95% and 80%, respectively. Through high-throughput sequencing, it was found that the dominant phylum of microorganisms changed obviously during the enrichment culture process, and the relative abundance of Planctomycetes of anammox bacteria increased from 1.43% to 10.40% in 48 d. The combination of anaerobic ammonia oxidation and membrane bioreactor can effectively enrich anaerobic ammonia-oxidizing bacteria in sludge, reduce sludge loss and realize rapid start-up of anaerobic ammonia oxidation.
