Abstract

Biofilm airlift reactor was continuously operated to investigate the competitions between the autotrophs and heterotrophs, ammonia oxidizers and nitrite oxidizers, and Nitrobacter and Nitrospira with real wastewater at a C/N ratio of 0.86. As the reactor achieved complete nitrification microbial distribution was analyzed by FISH/CLSM technique. The results showed that heterotroph was more abundant than nitrifying bacteria. Ammonia oxidizers (17%) and Nitrobacter (7%) prevailed nitrite oxidizers (9%) and Nitrospira (2%), respectively.
