AB  - In this study, the nitrogen removal performance and microbial characteristics of 
      completely autotrophic nitrogen removal over nitrite (CANON) process was 
      investigated with a step-wise increasing of C/N ratio (0.5, 1, 2 and 4) in a 
      membrane bioreactor. The microbial distribution of aerobic ammonia-oxidizing 
      bacteria (AOB) and anaerobic AOB (AAOB) was analysed by fluorescence in situ 
      hybridization (FISH). Results showed that the denitrification ratio rose up 
      correspondingly with the increase of influent C/N, and nitrogen removal rate 
      (NRR) reached the maximum when C/N was 1 due to the harmonious work of 
      denitrification and CANON. However, NRR decreased when influent C/N was more than 
      2. The threshold C/N ratio of CANON process was 2.2; so the sewage with a high 
      C/N ratio should be pretreated by combining with pre-oxidation of organics or 
      anaerobic-energy-producing process. FISH results showed decreasing numbers of 
      both AOB and AAOB with the addition of organics.
