| Abstract: | Objective] The aim was to discuss the effects of waste activated sludge by ultrasonic treatment. Method] The effects of operating factors including ultrasonic frequency, intensity, time and pH were studied and optimized by single factor altering gradually in a batch reactor. Result] The lower ultrasonic frequency could accelerate hydrolytic reaction of sludge to improve effects of sludge disintegration. The dissolved rate of SCOD, the disintegration rate of VSS and the temperature would be augmented when ultrasonic intensity, time and the pH value were increased. Conclusion] Ultrasonic process could be beneficial for sludge disintegration, would decrease the sludge output. |
