Abstract

The application of one-stage autotrophic nitrogen removal is hampered by its overlong start-up and instability under disturbance. A lab-scale batch tests were used to explore the optimal ultrasonic strengthening parameters, which were determined based on changes in the activity of the Canon system and EPS. The optimal ultrasonic intensity was 0.3 W/cm 2 , and the activity of Canon system was 40.68 mg N(gVSS-1 )d -1 . The optimal ultrasonic time was 4 min, and the activity of Canon system was 41.02 mg N(gVSS-1 )d -1 . Under the best ultrasonic intensity and ultrasonic time, it can be maintained for 6 days.
