Abstract:

A partial nitrification-ANAMMOX reactor system for domestic wastewater was set up, and the composition of N-related functional bacteria in the activated sludge were studied. During the stable period, the TN removal rate reached to about 80%. In the partial nitrification system, the dominant AOB is Nitrosomonas europaea/Nitrosococcus mobilis cluster-like bacteria, and the dominant NOB are Nitrobacter vulgaris-like bacteria and Nitrospira defluvii-like bacteria. In the anammox reactor, Kuenenia stuttgartiensis-like bacteria is the dominant anammox bacteria. Numerous members of proteobacteria, Chloroflexi, and Bacteroidetes/Chlorobi phylum are found to co-exist with anammox bacteria.

Key words: partial nitrification, anammox, ammonium oxidation bacteria (AOB), nitrite oxidation bacteria (NOB)
