Abstract： |
The present invention is on-line ultrasonic cavitation method and apparatus for cleaning membrane bioreactor for treating water and waste water. The on-line ultrasonic cavitation apparatus includes water inlet pump, bioreactor, membrane assembly inside the bioreactor and was outlet pump connected to the membrane assembly; and features the ultrasonic wave generator, which is set inside the bioreactor and is connected to one outer controller, and one differential pressure meter, which is mounted on to the membrane assembly water outlet pipe of the membrane assembly and connected via signal line with the ultrasonic controller. The present invention makes it possible not to take out the cleaned membrane assembly from the bioreactor, and has simple operation, short period, simple apparatus structure, stable operation and being favorable to automation and control. |
