Abstract

The invention belongs to the technical field of bioreactors, and particularly relates to an MBR (Membrane Biological Reactor) which comprises a box body, orientation plates are fixed on the inner walls of the two sides of the box body through bolts, orientation grooves are formed in the inner sides of the orientation plates, orientation blocks are slidably connected in the orientation grooves, and the same orientation spring is welded and fixed between the orientation blocks and the inner walls of the bottoms of the orientation grooves; the same air dispersing plate is fixed between the two directional blocks through bolts, densely distributed air dispersing holes are formed in the surface of the air dispersing plate, supporting rods are fixed to the tops of the directional blocks through bolts, first magnetic blocks are fixedly bonded to the rear ends of the tops of the supporting rods, a guiding mechanism is arranged at the rear end of the box body, and a water inlet mechanism, a water drainage mechanism and an aeration mechanism are arranged on the box body. According to the invention, the aeration mechanism is used for aeration, then the guide mechanism is used for driving the supporting rod to move up and down along with the orientation block and along with the orientation groove, and then the air dispersing plate is synchronously driven to move up and down, so that bubbles are uniformly dispersed and uniformly dispersed upwards through the air dispersing holes.

Description

Technical field

[0001] The present invention relates to the field of bioreactor technology, in particular to an MBR membrane bioreactor. Background

[0002] In the field of sewage treatment, water resources reuse, MBR, also known as membrane bioreactor, is a new type of water treatment technology combined with membrane separation unit and biological treatment unit, replacing the end of the conventional biological treatment technology with membrane modules, maintaining a high concentration of activated sludge in the bioreactor, improving the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and reducing the amount of residual sludge by maintaining a low sludge load.

[0003] At present, most of the membrane bioreactors of the membrane components are hollow filament membranes, and the aeration device is provided under each membrane module, which not only provides oxygen to the oxidation of the organism, but also prevents the activa...
