An MBR membrane bioreactor based on an A2O2 innovative process

Abstract

The invention discloses an MBR membrane bioreactor based on an A2O2 innovative process and relates to the technical field of wastewater treatment. The MBR membrane bioreactor includes a frame. Fixingplates are arranged on a pair of opposite side surfaces of the frame. A plurality of supports are fixedly mounted between the two fixing plates. The surfaces of the supports are rotatably connected tomembrane assemblies through bearings. Each membrane assembly includes a toothed disc both end surfaces of which are fixed to membrane supports, with one membrane support being provided with an axle tube at the axis center, one end of the axle tube being provided with a rotation connector, and the other membrane support being provided with a rotation shaft at the axis center. Through the toothed discs and the membrane supports, MBR membranes are supported to form sealed filtration chambers, filtered water is pumped out through the axle tubes at the axis centers, and the membrane assemblies arerotatably mounted on the frame. A motor, a transmission shaft and gears are linked with the toothed discs so that the membrane assemblies break the routine and have rotation filtration functions, thus sharing stress on an aeration pump, overcoming MBR membrane blockage and cleaning problems, saving the cost and increasing the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an MBR membrane bioreactor based on an A2O2 innovative process. Background technique [0002] A2O2 process technology is of great significance to promote the advanced treatment of wastewater in the metal surface treatment industry. Through the combination of A2O2, the dominant bacteria suitable for decomposing heavy metal wastewater refractory substances under the conditions of trace heavy metals and high salt content can be screened, and dominant bacteria can be established. Microbial ecosystems, optimize the process, and obtain the basic data for the expansion of the application of dominant colony processing. Membrane reactors play a very important role in domesticating dominant bacteria in the A2O2 process. Through the optimization of the control and management of membrane bioreactors, the effects of membrane cleaning methods and parameters, suction pressure, and memb...

Problems solved by technology

[0003] The purpose of the present invention is to provide an MBR membrane bioreactor based on the A2O2 innovative process. By designing a rotatable filter membrane module, the existing MBR membrane bioreactors are easy to block, the membrane is not easy to clean, and the aeration Disadvantages such as large energy consumption. In the process of acclimating the flora, once a failure occurs, the work efficiency will be greatly affected, and the energy consumption is large, and the production cost is high.
