  • The high-throughput sequencing technology was used to study the microbial characteristics of nitrosated granular sludge in aerated upflow sludge bed. The results showed that compared with the initial inoculated flocculent sludge,the sludge Shannon index increased from 3.869 to 4.590,which inicated the microbial population diversity of nitrosated granular sludge was more significant,and the relative abundance of Nitrosomonas in the sludge was reduced from 12.08% to 6.15%, and the relative abundance of Nitrobacter was reduced from 5.43% to 0.32%, which also indicated the nitrosation stability of nitrosated granular sludge was better.
