Abstract
The application relates to the technical field of sewage treatment, and discloses a membrane bioreactor and system based on piezoelectric vibration. The membrane assembly in the membrane bioreactor MBR comprises a composite membrane material and a membrane frame; the composite membrane material comprises piezoelectric material and MBR membrane material; the MBR membrane material is used for realizing solid-liquid separation; the piezoelectric material is used for driving the MBR membrane material to vibrate; the membrane frame is used for fixing two ends of a membrane filament in the composite membrane material, providing a membrane filament water production channel, a backwashing water channel and a cable channel, and forming a membrane assembly whole body with certain mechanical strength. The MBR membrane material is driven to vibrate through piezoelectric vibration, so that membrane pollution is inhibited, and the membrane water production efficiency and cleaning efficiency are improved.
