Put 13, second points of bubble releases 15 of device and the 3rd point of bubble release 17 releasing by parts in the transverse tube 65 of bubble release pipe 6
Microbubble, the collision of microbubble and the floc particle in sewage mixed liquor are sticked, and are formed density and are less than the bubble flco of water and pass through
Multiple tubules 66 are uniformly diffused into the bottom of whole air supporting reaction tank 1.The microbubble that main bubble release 11 discharges exists with sewage
Copolymerisation caused by relative reverse flow, makes caused flco bubble be clipped among wadding grain, microbubble plays in VERTICAL TUBE 62
Cohesion so that microbubble is embedded in inside flco securely, so that first point of bubble release, 13, second points of gas
The bubble flco to be formed is sticked in the collision of the microbubble and floc particle that are discharged in bubble release 15 and the 3rd point of bubble release 17
It is not easy to be desorbed during floating, scum silica frost is stable and is not easy.First point of bubble release 13, second is provided with transverse tube 65
Divide bubble release 15 and the 3rd point of bubble release 17, be to ensure to have enough microbubbles and flco in transverse tube 65
The situation of microbubble deficiency, will not occur in the end of transverse tube 65 in grain collision Adhesion.Bubble flco floats in air supporting reaction tank 1
To liquid level, scum silica frost is formed.Rotated by the sprocket wheel of slag-scraper 7, drive the scum board on chain in the surface water of air supporting reaction tank 1
Translation is dynamic, and scum silica frost is scraped in scum silica frost pond 3.Sewage occurs to revolve in reverse-impact and cyclone pipe 63 in VERTICAL TUBE 62 with microbubble
Turn mixing and stick in the same direction in transverse tube 65, improve the interaction of microbubble-particle, enhance the adhesion energy of microbubble
Power, the stability of bubble flco is enhanced, significantly increases microbubble particles collision efficiency, to the adaptability of sewage quality change
Significantly increase.Because sewage and microbubble during bubble discharges pipe 6 when reacting, part microbubble can form gas, this part gas
Body is discharged by blast pipe 61.Cut by adjusting 12, first points of main stop valve, 14, second points of stop valve stop valve 16 and the 3rd point
The only openings of sizes of valve 18, the release of 11, first points of bubble release, 13, second points of bubble release bubble can be become owner of with controlling stream
The flow of the dissolved air water of device 15 and the 3rd point of bubble release 17, so as to adapt to the water quality of different operating modes.
The aperture that the clear water of completion is set by the bottom of water pipe 5 is handled in air supporting reaction tank 1 and is collected and flow into clear water reserviors
2, the middle part of clear water reserviors 2 is distinguished water and returns pump to dissolving 9 by reflux pump 8, while air compressor machine 10 pressurizes and inputted sky to dissolving 9
Gas, air dissolve in clear water in dissolving 9 and form dissolved air water, and dissolved air water is discharged by main 11, first points of bubbles of bubble release
13, second points of bubble releases 15 of device and the 3rd point of bubble release 17 discharge microbubble circulation and reacted；In clear water reserviors 2
Another part clear water is flowed out by delivery port, completion processing.
A kind of multistage backflow air floatation machine provided by the present invention is described in detail above.It is used herein specifically
Individual example is set forth to technical scheme and embodiment, and the explanation of above example is only intended to help and understands this
The technical scheme and its core concept of invention.It should be pointed out that for those skilled in the art, do not departing from
