Specific embodiment
With reference to a kind of membrane filtration shown in Fig. 1-2 and aeration integrated device, including upper cavity 27, lower chamber 28 and close
Envelope is connected to the cylinder filter membrane 2 between upper cavity 27 and lower chamber 28.The upper cavity 27 and lower chamber 28 are disk
Structure, it is microfiltration membranes or ultrafiltration membrane that filter membrane 2, which selects filter membrane, and the both ends of filter membrane 2 are respectively around upper cavity 27 and the circle of lower chamber 28
Week is tightly connected.
Supporting rod 29 is connected between the center of the upper cavity 27 and the center of lower chamber 28, around the supporting rod 29
There are six water channel demarcation strip 25, one side of the water channel demarcation strip 25 to be connect with supporting rod 29 for distribution, water channel demarcation strip 25 it is another
There are two air flue demarcation strip 26, the angle between two water channel demarcation strips 25 of arbitrary neighborhood is 60 ° for connection on one side（Specific water channel
The quantity of demarcation strip 25 can need to adjust according to pending water quality, and the quantity of corresponding inlet channel 22 can also become therewith
Change）.Described two air flue demarcation strips 26 are in contact to form the inlet channel 22 of segment with filter membrane 2, the filter membrane 2 of inlet channel 22
Surface is oxygen supply Diffusion barrier layer 23 for gas to pass through.
Filter membrane between two water channel demarcation strips, 25, two inlet channels 22 of arbitrary neighborhood and two inlet channels 22
2 are collectively formed drainage channel 21；As supply water the membrane filtration layer 24 passed through on 2 surface of filter membrane of drainage channel 21.
Because it is non-fixed structure between membrane filtration layer 24, oxygen diffusion membrane layer 23 and air flue demarcation strip 26（Only play contact branch
Support is acted on and is not connected to）, membrane filtration outer layer scaling fouling object is washed away so as to be realized by gas disturbance.
The upper cavity 27 is connected with outlet pipe 13, and lower chamber 28 is connected with air inlet pipe 33, the inlet channel 22 it is upper
End connects and closes with upper cavity 27, and the lower end of inlet channel 22 is connected with 28 inside of lower chamber；The drainage channel 21 it is upper
End is connected with 27 inside of upper cavity, and the lower end of drainage channel 21 connects and closes with lower chamber 28.
The application method of the present invention is as follows：
By taking certain biochemical waste water treatment pool 4 as an example, six present apparatus are positioned over side by side in biochemical waste water treatment pool 4, configuration is corresponding
The Aeration fan 31 of power blows to device, and gas is evenly distributed to through air inlet supervisor 32, air inlet pipe 33 in each device, gas
Body enters from lower chamber 27, enter back into each inlet channel 22, and gas is being formed by air flue demarcation strip 26 and oxygen diffusion membrane layer 23
It inside fan-shaped gas inlet channel 22, is laterally aerated through oxygen diffusion membrane layer 23 to water body, since gas is spread continually by oxygen
Film layer 23 is acted on the gas specific surface area increase entered in water body by film, is effectively improved oxygen transfer efficiency, accelerates
The degradation of dirty Organic substance in water.
By generating faint vibration during oxygen diffusion membrane layer 23, air flue demarcation strip 26 only contacts gas with filter membrane 22 simultaneously
And be not fixed, the biofouling of the membrane filtration layer 24 of adjacent drainage channel 21 is made to be washed and come off.
At the same time, the water through aeration purification in sewage, under the action of suction pump 11, in formation in drainage channel 29
Negative pressure, water body by membrane filtration layer 24 enter drainage channel 21 in, purified sewage after by filter membrane 2 well with work
Property sludge separation, water outlet main pipe 12 is pooled to by each outlet pipe 13 after collecting, and with 11 discharge system of suction pump outside, so as to obtain
The water outlet of high quality.
The above, preferable specific embodiment only of the invention, but the scope of the present invention is not limited thereto, and it is any
Those familiar with the art is in the technical scope of present disclosure, the change or replacement that can readily occur in, all should
It is included within the scope of the present invention.Therefore the scope of the present invention is subject to the protection domain of claims.
