Description
Technical field
The invention belongs to field of waste water treatment, more particularly to a kind of spraying waste water air-floating processing apparatus.
Background technology
It is more to spray contaminated wastewater species, water quality, water fluctuation are larger, can be removed using air-float technology therein floating
The pollutants such as oil, suspension, heavy metal.
Traditional air-float technology, air dissolving system is that part flotation tank water outlet is pumped into dissolving using water circulating pump, molten
There is packing layer in gas tank, gases at high pressure are passed through in dissolving, gases at high pressure and flotation tank water outlet mix between the filler of dissolving
Close, under conditions of high pressure, the solubility of air increases, and generates high pressure dissolved air water.Dissolving water outlet (high pressure dissolved air water) is passed through
Dissolved air release is discharged, and because pressure die-offs after discharge dissolved air release, the air in dissolved air water can discharge, and generate small gas
Bubble, sticks with the suspension in waste water, generates scum silica frost, then strike off through Slag Scraping Device.
But because spraying waste water impurity is more, cause molten gas tower packing and dissolved air release in air dissolving system easily to block,
Have a strong impact on the normal operation of air-flotation system.
The content of the invention
Problem present in view of the aforementioned technical background, thus the invention provides a kind of spraying waste water air-flotation process
Equipment is to solve the above problems.
The technical solution adopted by the present invention is：
One kind spraying waste water air-floating processing apparatus, are made up of hybrid reaction system, air dissolving system, air supporting cell system, described
Hybrid reaction system is used to add demulsifier and coagulant, to generate bulky grain suspension, is removed beneficial to follow-up air supporting；It is described molten
Gas system is made up of circulatory pool, filter, gas-liquid mixing pump, dissolved air release, and its major function is generation dissolved air water, and release is molten
Gas, for air supporting；The air supporting cell system is used for suspension and sticked with the molten gas after release, and virtue of buoyancy floats up to flotation tank pond
Face, removal is blown off using Slag Scraping Device.The hybrid reaction system is made up of the pond that is demulsified, coagulation reaction tank, flocculation tank.It is led
It is to add demulsifier and coagulant to want function, to generate bulky grain suspension, is removed beneficial to follow-up air supporting.The air supporting cell system
It is made up of flotation tank, molten gas release area, air supporting reaction zone, combustion chamber hopper, ash pit, sludge scraping slag machine.Its major function is to suspend
Thing sticks with the molten gas after release, and virtue of buoyancy floats up to flotation tank pond face, and removal is blown off using Slag Scraping Device.
The equipment can effectively remove the pollutants such as the oil slick sprayed in waste water, suspension, heavy metal.Simultaneously by using gas
Liquid mixing pump replaces dissolving, increases circulatory pool and filter, effectively prevent the blocking of air dissolving system, and it is useless to be truly realized spraying
The efficient process of water.The equipment is efficiently solved in general air-flotation process system, the blockage problem of air dissolving system.The present invention is with passing
System spraying waste water air-float technology contrast, operation is more stable, and maintenance work is less.
Beneficial technique effect caused by the present invention：
The invention provides a kind of equipment for spraying wastewater treatment, the molten gas of big volume is replaced using gas-liquid mixing pump
Tower, efficiently solve in general air-flotation process system, the blockage problem of molten gas tower packing, at the same newly-increased circulatory pool and filter, resistance
Every debris, efficiently solve in general air-flotation process system, the blockage problem of dissolved air release, realize at spraying waste water air supporting
The stable operation of reason system, reduce human hand and safeguard.
Brief description of the drawings
Accompanying drawing 1 is the plan of the equipment of the present invention；
Accompanying drawing 2 is the A-A profiles of the equipment of the present invention；
Accompanying drawing 3 is the process chart of the equipment of the present invention.
Embodiment：
As illustrated in the accompanying drawings from 1 to 3, a kind of spraying waste water air-floating processing apparatus, by hybrid reaction system, air dissolving system, flotation tank
System forms, and the hybrid reaction system is used to add demulsifier and coagulant, to generate bulky grain suspension, beneficial to follow-up gas
Floating to remove, the air dissolving system is used to generate dissolved air water, discharges molten gas, for air supporting, the air supporting cell system is used for suspension
Stick with the molten gas after release, virtue of buoyancy floats up to flotation tank pond face, and removal is blown off using Slag Scraping Device.The hybrid reaction system
System is by being demulsified pond (1), coagulation reaction tank (2), flocculation tank (3) form, and its major function is to add demulsifier and coagulant,
To generate bulky grain suspension, removed beneficial to follow-up air supporting.The air dissolving system by circulatory pool (5), gas-liquid mixing pump (6), every
Net (7), dissolved air release (8) composition, its major function are generation dissolved air waters, molten gas are discharged, for air supporting.The flotation tank system
System is by flotation tank (4), molten gas release area (9), air supporting reaction zone (10), combustion chamber hopper (11), ash pit (12), sludge Slag Scraping Device
(13) form, its major function is suspension and the molten gas after discharging sticks, and virtue of buoyancy floats up to flotation tank pond face, using scraping
Slag machine blows removal off.
Operation principle：
The spraying boosted pump of waste water is promoted to demulsification pond, adds sulfuric acid, the oil emulsion in waste water is become big, floats.Water outlet
Into coagulating basin, feeding lime, make the sludge such as the heavy metal in waste water, suspension thing generation precipitation.Water outlet enters flocculation reaction
Pond, PAM is added, utilize PAM adsorption bridging effect generation bulky grain suspension.Water outlet enters the molten gas release area of flotation tank, greatly
Particle suspensions are sticked with tiny bubble caused by dissolved air release, air supporting pool surface are floated in air supporting reaction zone, through scraping
Slag machine, which is scraped to ash pit, to be removed.Sediment in flotation tank is precipitated to sediment groove, is periodically emptied through valve.Flotation tank water outlet is entered
Enter circulatory pool, the water outlet of circulatory pool part enters gas-liquid mixing pump after filter, to produce high pressure dissolved air water, then through dissolved air release
Disengage bubble.Filter has obstructed debris entrance, reduces the blocking of dissolved air release.Gas-liquid mixing pump instead of equipped with filler
Dissolving, the problem of having prevented impurity, sludge blockage dissolving filler.The water outlet of circulatory pool major part enters subsequent treatment process,
To remove other pollutants.
Above-mentioned detailed description is illustrating for one of the present invention practicable embodiment, and the embodiment simultaneously is not used to limit
The Patent Law scope of the present invention is made, all equivalence enforcements or change without departing from carried out by the present invention, is intended to be limited solely by the patent of this case
In scope.
