Problems solved by technology

Chemical cleaning can effectively remove gel layer and membrane pore pollution, but it is necessary to take out the membrane module and place it in another prepared pool or release the sludge, which is complicated to operate; mechanical cleaning mainly solves the pollution of the mud cake layer, usually after washing with tap water, The way of sponge ball scrubbing also needs to take out the membrane module
In engineering applications, there are disadvantages of complex operation

Embodiment 1

[0031] See attached figure 1 , 2 , 3 and 4. The membrane filament of the hydrophilic membrane module 3 is a hollow fiber microfiltration membrane 1, one end is closed, and the other end is connected to the water collection pipe 2. 4 connected. The membrane filaments of the hydrophobic membrane module 7 are hollow fiber membranes 5 placed in parallel with the hydrophilic membrane module 3 . Rotating brush 12 is made up of adjustable speed motor 9, base frame 10 and hair brush 11, and the rotation of adjustable speed motor drives base frame 10 and hair brush 11 to rotate. The bioreactor 14 is cylindrical, and is connected with an inlet pipe 8 , a water inlet pipe 13 , an outlet pipe 4 and an exhaust pipe 15 , and has a built-in rotating brush 12 . The waste water enters the bioreactor 14 through the water inlet pipe 13, and the hydrophobic membrane module 7 is bubble-free oxygenated so that the oxygen in the reactor 14 is sufficient. The rotation of the rotating brush 12 in...

Abstract

A rotary brush type membrane bioreactor for water treater is composed of the membrane unit consisting of water permeable hydrophilic membrane unit and aerating hydrophobic membrane unit, the rotary brush consisting of speed-adjustable motor, basic frame, and brush, and the bioreactor. Said hydrophilic membrane unit comprises membrane and water collecting tubes. Said hydrophobic membrane unit comprises membrane wires and aerating tubes.

Description

technical field [0001] The invention belongs to the field of membrane bioreactors, in particular to a rotary brush type membrane bioreactor. Background of the invention [0002] The known membrane bioreactor, in which the membrane separation replaces the secondary settling tank in the traditional water treatment technology, has high microbial concentration, impact load resistance, good effluent quality, SRT and HRT can be independently controlled, and the remaining sludge output is small, occupying an area Small area and other advantages. However, membrane fouling causes fast attenuation of membrane flux, requires a large investment in membrane area, high energy consumption to overcome membrane fouling, high sludge concentration, low oxygen mass transfer efficiency, and high oxygen consumption, which hinder membrane bioreactors. Bottleneck problem for widespread adoption of technology. [0003] Membrane fouling can be divided into internal poll...
