Description

The high-speed air floatation water treatment device
Technical field
The invention belongs to technical field of waste water processing, relate to wastewater treatment equipment, especially a kind of high-speed air floatation water treatment device.
Background technology
In water supply and drainage treatment process program, solid, liquid stripping technique and equipment thereof are one of key projects.The dissolved air flotation method is mainly used in partition density and the near suspended matter of water, and in the waste water of suspended substance sedimentation poor-performing.
Airfloat equipment adopts the conventional load air flotation technology at present, and this kind equipment has the stirring of mixing and two ponds of air supporting.The sewage that mixes in the agitated pool produces " flocs unit " under the chemical action of flocculation agent and coagulating agent; " flocs unit " along with current flow into the mixing contact area of air flotation pool, and with a large amount of microbubbles mutual bonding become " being stained with the gas flco ", its volume density is less than water; " be stained with the gas flco " and rise to the water surface very soon; Accomplish dissolved air flotation, suspended substance gathers into scum silica frost at the liquid level knot, scrapes the purpose that collection has promptly reached solid-liquid separation to scum silica frost.Therefore kind equipment has the stirring of mixing and two ponds of air supporting, so floor space is big, cost is high.
Summary of the invention
The objective of the invention is to overcome the deficiency in existing conventional load air-float technology and the equipment, being put into completion in the air supporting mixing contact area at chemical reaction process that mixes agitated pool medicament and sewage and product " flocs unit ".Chemical coagulation reaction and microbubble mixing are contacted the two perfect fusion in a pond body, can improve the surface load (surface load can reach 10-25M3/M2/h) that air supporting is handled greatly; Improve processing efficiency, practiced thrift manufacturing cost, reduced floor space.
According to technical scheme of the present invention, a kind of high-speed air floatation water treatment device is characterized in that being made up of air flotation pool body, mixing stir storehouse, mixing and blending machine, microbubble generator, backflow water pump, air compressor machine and dissolved air release.Air flotation pool body and microbubble generator link together through backflow water pump and pipe valve.Microbubble generator also is connected with air compressor machine through pipeline; Mix stir storehouse and be positioned at air flotation pool body middle part; Be installed on the chassis of being fixed in air flotation pool body base plate; Mixing and blending machine is fixed on the top of air flotation pool body, and makes the mixing paddle of one of which end be in the bottom of mixing in the stir storehouse, and dissolved air release is installed in air flotation pool body bottom through support and is connected with microbubble generator through pipeline; Mix periphery, stir storehouse bottom be equipped with the clear water collection tube and and the clear water pipe coupling of air flotation pool body one side; Mix in the stir storehouse that the coagulating agent chemical feed pipe also being installed, air flotation pool body top is provided with that mud drainage slot, bottom are provided with the sewage import, a upper lateral part is provided with clear water and effluxes mouth, and the mud drainage slot terminal is equipped with the scum silica frost outlet.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As attach shown in Fig. 1 and 2:
The import of 1-sewage, 2-clear water collection tube, 3-air flotation pool body, 4-dissolved air release, 5-coagulating agent chemical feed pipe, 6-mixing stir storehouse, 7-mixing and blending machine, 8-mixing paddle, 9-mud drainage slot, 10-clear water pipe, 11-clear water efflux mouth, 12-pipe valve, 13-microbubble generator, 14-air compressor machine, the outlet of 15-scum silica frost, 16-backflow water pump,
Air flotation pool body 3 links together through backflow water pump 16 and pipe valve 12 with microbubble generator 13.Microbubble generator 13 also is connected with air compressor machine 14 through pipeline; Mix stir storehouse 6 and be positioned at air flotation pool body 3 middle parts; Be installed on the chassis of being fixed in air flotation pool body 3 base plates; Mixing and blending machine 7 is fixed on the top of air flotation pool body 3, and makes the mixing paddle 8 of one of which end be in the bottom of mixing in the stir storehouse 6, and dissolved air release 4 is installed in air flotation pool body 3 bottoms through support and is connected with microbubble generator 13 through pipeline; Mixing periphery, stir storehouse 6 bottom is equipped with clear water collection tube 2 and is connected with the clear water pipe 10 of air flotation pool body 3 one sides; Mix in the stir storehouse 6 that coagulating agent chemical feed pipe 5 also being installed, air flotation pool body 3 tops are provided with mud drainage slot 9, bottom and are provided with sewage import 1, a upper lateral part and are provided with clear water and efflux mouthfuls 11, and mud drainage slot 9 terminals are equipped with scum silica frost outlet 15.
Microbubble generator 13 at the high-pressure air that utilizes jet current principle that air compressor machine 14 is produced under the effect of backflow water pump 16 and water under certain pressure and condition; Make gas dissolve in the water to the utmost; Make every effort to be in state of saturation, produce a large amount of microbubbles to formed pressure air-dissolving water through dissolved air release 4 then.
Sewage flows in the mixing stir storehouse 6 of air flotation pool body 3 through sewage import 1; Pollutent generation chemical reaction produces flocs unit in flocculation medicament that in this is interval, adds through coagulating agent chemical feed pipe 5 and the sewage; The microbubble thorough mixing that this flocs unit produces with dissolved air release 4 under the rotation stirring action of mixing paddle 8 contacts and forms the flco of specific density less than water; Flco inner inclusion microbubble is called " gas enclosure flco "; Its volume density is less than water, and along with the flotation separation zone that flows on the current direction in the air flotation pool body 3, " gas enclosure flco " rises to water surface knot very soon and gather into scum silica frost.Scum silica frost is collected under the effect of mud drainage slot 9, through scum silica frost outlet 15 discharging regularly.
In the flotation separation zone, remove most suspended substance, reached the purpose of solid-liquid separation.Clear water is collected through clear water collection tube 2 and is entered clear water zone through clear water pipe 10.Clear water is in this interval, and a part flows downward to be taken away to squeeze in the microbubble generator 13 by backflow water pump 16 and produces dissolved air water; Another part upwards flows into 11 dischargings of clear water drain.
