Outline of Final Research Achievements

The possibility of Anammox attached film expanded bed reactor applied for high nitrogen loading rate is investigated in a continuous experiment. At the high nitrogen loading rate, the TN removal efficiency reached around 88%, and maximum specific Anammox activity showed 0.68 gN/gVSS/d. The Anammox granule formed in the reactor showed very good settleabolity with a setting velocity over 263.1 m/h. It was revealed that Anammox attached film expanded bed reactor is suitable for high nitrogen loading rate.
