Floor space is little, with important practical significance.But in long-term practical application, membrane bioreactor also shows one
A little weak points, such as fouling membrane phenomenon is more serious, and fouling membrane can cause the decay of membrane flux, so needing frequently to clean
And maintenance.
The existing means for solving the above problems are to produce cross-flow on film surface, and the gas that for example aerator is produced is with mixed
Close liquid flow up, film surface produce shear stress, in the presence of this shear stress so that be deposited on film surface
Grain departs from film surface.Realize that this point requires the expenditure of energy, the cost of raising.Therefore one kind is needed to make full use of outside
The air of input, efficiently goes as far as possible the processing equipment of the pollutant on membrane removal surface.
The content of the invention
It is an object of the invention to provide a kind of pollutant for being capable of efficient process film surface, improves capacity usage ratio
Processing equipment.By arranging deflector above aeration head, the propeller agitator on the upside of membrane bioreactor is coordinated to realize
The purpose.
In order to reach the purpose, the present invention is adopted the following technical scheme that：Including membrane biological reaction room, water inlet and water outlet
Mouthful, it is characterised in that：Also include membrane bioreactor, the membrane bioreactor includes membrane component and for fixing the film
The framework of element, the membrane component surface bottom surface, the company of being relatively set with the framework in the membrane biological reaction room
First strut and the second strut of membrane biological reaction room side wall are connect, side is provided with compressed air in the membrane biological reaction room
Pipe, aeration head of the air hose connection below the membrane bioreactor, the aeration head and the membrane biological reaction
The deflector of control airflow direction is provided between device.
Thus, the flow direction of the gas that deflector control aeration head is produced, improves capacity usage ratio.
As one kind preferably, the deflector is the flat board being oppositely arranged, and the flat board is from top to bottom gradually to the film
Biological respinse room side wall is close, as much as possible through membrane bioreactor to ensure gas and mixed liquor, and it is biological to change film
The gas of reactor sidepiece and the flow direction of mixed liquor.
As one kind preferably, the deflector is located at 60 ° to 80 ° with the angle of horizontal plane, to ensure gas and mixed liquor
Overall flow direction.
As a kind of preferred, above the membrane bioreactor propeller agitator, the propeller are provided with
The rotation axis of device is inclined and points to the membrane bioreactor middle part.
Thus, propeller agitator can be such that gas and mixed liquor contacts with membrane module for a long time as far as possible.
As it is a kind of preferably, the quantity of the propeller agitator is four and is evenly distributed on the membrane biological reaction
Device sidepiece.
As one kind preferably, the rotation axis of the propeller agitator is 30 ° relative to the angle of inclination of vertical line.
To sum up, the present invention has advantages below：
1）The flow direction of the gas that deflector control aeration head is produced, makes gas and mixed liquor as much as possible through membrane biological reaction
Device, increases operation rate.
2）The setting of propeller agitator can be such that gas and mixed liquor contacts with membrane module for a long time as far as possible, carry
The efficiency of height cleaning film surface contaminant.
