Description
Technical field
One kind involved in the present invention is porous while aerator, belongs to water treatment field.
Background technique
In sewage treatment, water resource recycles field, and membrane bioreactor (Membrane Bio-Reactor, MBR) is
A kind of novel water treatment technology combined by activated sludge process with membrane separation technique.Compared to conventional process mode, using MBR
Membrane process has the main features such as few effluent quality high-quality stable, excess sludge production, occupied area saving, operational administrative be convenient
And advantage.In actual moving process, in order to safeguard the film surface cleaning of MBR film, object siltation is avoided pollution, often in a manner of aeration pair
MBR film implements film scouring.
Traditional aerating system (such as perforated pipe aerating regulation, micro-pore aeration) is arranged in membrane cisterna bottom, by aerator, air blower,
The composition such as valve and controller.Air blower constantly supplies air, and system is provided to aerator big in a short time by pipeline
Air is measured, one strand of bubble is transferred to MBR film group by aerator, helps the pollution for inhibiting film surface.
However there are drawbacks for above two aeration mode.It is long for perforation Pipeline for perforated pipe aerating regulation, Kong Duo,
In order to generate sufficiently large enough bubbles, perforated pipe aerating regulation needs a large amount of air and arrangement is intensive as far as possible, in this way
Sufficiently large enough bubbles could be generated to go to clean film surface, and bubble also compares greatly very much concentration, non-uniform can wash away
The film surface of part will lead to diaphragm for a long time and wash away and unevenly washes away always local to be washed damaged and wash away less than then
Can silt deposit block film filter capacity caused to decline, will also result in that energy consumption is excessively high, and water process unit price is consequently increased, perforated pipe
Increase and also valve caused to increase, manufacturing cost is further up, and excessive valve is in daily production also due to ceaselessly
Damage cause maintenance cost higher；For micro-hole aerator, the bubble that micro-pore aeration generates is uniform, exposes relative to perforated pipe
Gas, the relatively uniform energy-saving benefit of micro-pore aeration are more preferable.But micro-pore aeration to MBR membrane cisterna oxygenation capacity be 3 times of perforated pipe with
On, and micropore manufacturing cost installation and debugging cost is also all very high.It causes the increase of reflux ratio and is discharged the raising of total nitrogen, water outlet
Water quality is unstable, and water process unit price is not advantageous compared to perforated pipe aerating regulation.
Another obvious drawback are as follows: both the above aeration mode is all to drive sewage to wash away upwards with bubble stream.To film
The scouring effect on surface is undesirable, needs to carry out film group periodically offline cleaning.And the workload cleaned offline is very huge.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of porous while aerators, including air inlet, uniform cloth
Tracheae line structure and outlet accent, the air inlet supply entire aerator, the air inlet and the uniform cloth
Tracheae line structure is connected, and the uniform gas distribution pipeline structure is equipped with the similar several pipelines of inner-cavity structure, the uniform gas distribution
Each pipeline of pipeline structure is connected with the outlet accent.
In above-mentioned porous while aerator, the air inlet is located at intermediate below described porous while aerator
Place.
The air inlet is placed in the lower section middle of the present apparatus, and bubble floats automatically after coming in enters uniform gas distribution pipeline knot
Structure.
The uniform gas distribution pipeline structure is equipped with several pipelines, the aeration bubbles come out for distributing air inlet, in conjunction with pressure
(preferred center is symmetrical for the various structures of power, the hydrodynamics of volume caliber and aerodynamic correlation theory repetition test
Spiral lumen distribution), finally realize multiple outlet accents outlet and how much consistent gas output is simultaneously.And examination repeatedly
Test room verifying show the mode of this uniformly distributed bubble be provided simultaneously with that perforated pipe aerating regulation scrub effect is good and micro-pore aeration scouring
Even advantage, and energy consumption substantially reduces, and is in industry a kind of introducing of completely new approach.And due to outlet chamber in the present invention
The special designing of mouth, bubble roll away in the moment gone out, rather than emit up, it can thus generate more wipings
Kinetic energy is washed, cyclone vortex is formed when bubble rises, substantially increases scrub effect.
In above-mentioned porous while aerator, the number of the outlet accent is 8, is uniformly divided around air inlet center
Cloth.
The outlet accent is for guiding air quickly to flow out；The quantity of the outlet accent can be various quantity, make
To be preferred, 8 are used in this programme, the outlet accent of other quantity also belongs in this patent scope.The characteristics of this patent
Be no matter the number of quantity, outlet is all uniformity, and outlet simultaneously.
In above-mentioned porous while aerator, the air inlet is for pipeline or hole or thoroughly independently of the present apparatus
The device of gas supply, the work that those skilled in the relevant art do not have to pay creativeness can reach the same all categories for supplying effect
In in this patent scope.
The quantity of the air inlet can be 1 or 1 or more.
Preferably, the air inlet, uniform gas distribution pipeline structure and outlet accent are done by the way of mold injection
Civilian use cost is reduced to adapt to national call at a part, convenient for promoting.Other parts or all using assembly
What mode formed said function and effect also belongs to this patent scope.
Preferably, this programme air inlet be made of one all in installation from debugging；Further, the present apparatus is put
It is the same in the case where there is no included gas outlet above other various gas outlets to carry out automatic uniform secondary distribution to air-flow,
This combined usage mode is also considered as equivalent infringement.
Preferably, the occasion for being used in aeration of this programme description, can play the maximum efficiency of aeration in this way.Into
One step, lasting gas supply and intermittent gas supply such as poling aeration can also carry out secondary uniform distribution to gas using the present apparatus, have
Effect ground, which improves, washes away area, and the similar intake method that changes also is considered as equivalent infringement.
It is an object of the present invention in MBR film pretreating process with it is novel porous and meanwhile be aerated swab substitution wear
Hole pipe aeration and micro-pore aeration.The invention can be in conjunction with the advantages of boring aeration and micro-pore aeration:
1, it can be achieved with the scrub effect of MBR film using lower air demand, air demand is only the 1/3 of perforated pipe.
2, MBR membrane cisterna oxygenation capacity is low, can reduce reflux ratio, improves effluent quality.
3, when being aerated work, while washing away upwards with air driven sewage, a large amount of spinnings can be generated
Vortex, just as with rag wipe.To greatly reinforce the dynamics cleaned to film surface, effectively prevent the dirt of film surface stifled
With the growth of bacterium.
4, in the unit area, make distribution outlet more uniform, can uniformly wash away corresponding whole diaphragms, solve office
Portion's silt deposit blocks the problem of filter capacity decline and has effectively cleaned diaphragm and protected diaphragm from damage, significantly
Extend the service life in period and diaphragm that diaphragm cleans offline.
5, when film is backwashed, more dirty stifled objects can be taken away.Increase the service life of MBR film.
