| Outline of Final Research Achievements |
We succeeded in establishment of a single-stage partial nitritation and anammox process by membrane bioreactor (PNA by MBR). The strategy is that partial-nitritation (PN) process was established by inoculating ammonium-oxidizing bacteria (AOB) at first and subsequently PNA process was established by inoculating anammox bacteria. As a result, establishment of PNA by MBR was succeeded and maximum-nitrogen removal rate and maximum-nitrogen removal efficiency of 1.45 kg-N/m3/d and 89.5% were achieved. The results of bacterial community analysis indicates that genus Nitrosomonas and genus Nitrosospira species are dominant as ammonium oxidizing bacteria, and Candidatus Brocadia”species were dominant.
