State the bottom of the second bubble release 15 installation inner cylinder 5.
The bottom of 11 one end of water inlet pipe connection bubble release pipe 6, one end connection nozzle 12, the nozzle 11 are mounted on
The bottom of inner cylinder 5.
In the embodiment, the specific implementation process of sewage disposal is as follows：
For sewage after air supporting water inlet flows into air floatation machine, the flocculant flowed into dosing mouth passes through static mixer 17 together
Mixing, then flow into VERTICAL TUBE 62 from the top of bubble release pipe 6；A part of dissolved air water in dissolving 9 is released by first bubble
It puts device 13 and discharges microbubble, the dissolved air water with microbubble flows into the bottom of VERTICAL TUBE 62, and sewage is with microbubble in VERTICAL TUBE 62
With respect to reverse flow, complete the abundant collisional mixing of microbubble and the wadding grain in sewage, microbubble participate in coacervation process and and
The copolymerization of wadding grain is simultaneously big, so as to generate copolymerisation, forms bubble wadding copolymer；Microbubble and sewage co-flow again, by eddy flow
Pipe 63 further rotates mixing, and completion is effectively sticked, then in being diffused into air supporting reaction tank 1 by water inlet pipe 11, nozzle 12
5 bottoms of cylinder.Another part dissolved air water in dissolving 9 is by the second shut-off valve 16, the second bubble release 15 in 5 bottom of inner cylinder
Microbubble is discharged, the collision of the floc particle in the sewage mixed liquor that microbubble is flowed out with nozzle 12 is sticked, and is total in inner cylinder 5
It is same to flow up.The big cross-sectional area 52 of inner cylinder 5 including bottom and the small bore area 51 at top, dissolved air water at big cross-sectional area 52,
Since sectional area is big, the current rate of climb is uniformly slow so that the mesh of flco network structure is more uniform, in small bore area 51
When, since sectional area is small, unit area microbubble density becomes larger, and the mesh of flco network structure becomes smaller, and air flotation effect is more preferably.The
The copolymerisation that the microbubble of one bubble release 13 release is generated with sewage in VERTICAL TUBE 62 with respect to reverse flow, makes generation
Flco bubble be clipped in wadding grain among, microbubble has played cohesion so that microbubble is embedded in inside flco securely, from
And the collision of microbubble and floc particle in the release of the second bubble release 15 is caused to stick the bubble flco to be formed in floating
It is not easy to be desorbed in the process, scum silica frost is stable and is not easy.Bubble flco floats up to liquid level in inner cylinder 5, forms scum silica frost.By scraping slag
The sprocket wheel of device 7 rotates, and the scum board on chain is driven to move horizontally, scum silica frost is scraped in scum silica frost pond 3.Sewage is discharged in bubble
Reverse-impact occurs with microbubble in pipe 6 and rotation is mixed and sticked in the same direction in inner cylinder 5, improves microbubble-particle
Interaction enhances the Adhering capacity of microbubble, enhances the stability of bubble flco, makes microbubble particles collision efficiency notable
Enhancing significantly increases the adaptability of sewage quality variation.Since sewage and microbubble during bubble discharges pipe 6 when reacting,
Part microbubble can form gas, this portion gas is discharged by exhaust pipe 61.By adjusting the first shut-off valve 14 and second section
The only openings of sizes of valve 16 can control the stream for the dissolved air water for flowing into first bubble release 13 and the second bubble release 15
Amount, so as to adapt to the water quality of different operating modes.
The clear water that completion is handled in inner cylinder 5 flows into the region between 1 pool wall of air supporting reaction tank and 5 barrel of inner cylinder, and passes through
The clear water hole 41 that is set on partition plate 4 flows into clear water reserviors 2, and 2 middle part of clear water reserviors is distinguished water and returns pump to dissolving 9 by reflux pump 8, simultaneously
Air compressor machine 10 pressurizes to dissolving 9 and input air, and air dissolves in clear water in dissolving 9 and forms dissolved air water, and dissolved air water flows into
First bubble release 13, the second bubble release 15 release microbubble Xun Huan and are reacted；Another part is clear in clear water reserviors 2
Water is flowed out by water outlet, completion processing.
