Abstract
The utility model provides a kind of new microbubble aerobe aeration tank, including aeration tank body, the side of the aeration tank body is provided with an outer circulation oxygen replenishing equipment, and the two ends of the outer circulation oxygen replenishing equipment connect aeration tank body by outer circulation oxygenation water inlet pipe and outer circulation oxygenation outlet pipe respectively.The aeration tank body interior is provided with a plurality of aeration tube.Some solarization air caps are provided with every aeration tube, one end of every aeration tube is connected and installed in one end of the air inlet pipe of aeration tank body exterior side, the other end connection air blower of the air inlet pipe simultaneously.This patent carries out preliminary oxygenation using the non-damageable aeration tube with solarization air cap to aeration tank, while playing stirring action, it is ensured that muddy water mixed effect.Depth oxygenation is carried out to aeration tank body by sewage outer circulation using external outer circulation oxygen replenishing equipment again, the process improves the dissolved oxygen in sewage using air substitute mode, the dissolution of contaminated water oxygen value after oxygenation is far above conventional aeration method.Finally on the premise of the low maintenance rate of aerator, the aerobic biodegradation of pollutant is realized.
Description
Technical field
The utility model is related to a kind of aeration tank, especially a kind of simple and reliable for structure, designs ingenious, high working efficiency
New microbubble aerobe aeration tank.
Background technology
Activated sludge process is the main method of the biological wastewater treatment based on activated sludge.Activated sludge process is to useless
Air continuously is passed through in water, the sludge-like flocculate formed because aerobic microorganism is bred after certain hour.Perch thereon
The micropopulation based on zoogloea, the ability with very strong absorption Yu oxidation of organic compounds.
The method is under artificial aerobic condition, sewage and various micropopulations to be continuously mixed, and is formed and lived
Property sludge.Using the biological flocculation and precipitation of activated sludge, absorption and oxidation, to decompose the organic pollution in removal sewage.So
After be separated from water sludge, most of sludge is back to aeration tank again, and redundance then discharges activated Sludge System.
Typical activated sludge process is made up of aeration tank, sedimentation basin, sludge recirculation system and excess sludge removal system.
Sewage and the activated sludge of backflow enter aeration tank and form mixed liquor together.From the compressed air that air compressor station is sent, lead to
The air-diffuser for being laid on aeration tank bottom is crossed, is entered in sewage in the form of the tiny bubble, it is therefore an objective in increasing sewage
Dissolved oxygen content, also make mixed liquor be in vigorous agitation state, in suspended state.Dissolved oxygen, activated sludge and sewage are mutual
Mix, be fully contacted, activated sludge reaction is normally carried out.Influence activated sludge process operating efficiency (treatment effeciency
And economic benefit) principal element be that selection and the aeration mode of processing method is designed and run.
As the core cell of activated sludge process, oxygen system mainly from oxygen supply Aeration fan and special aerator constitute to
Enough dissolved oxygens are provided in aeration tank, and mud, water are fully contacted by bubble agitation mixed liquor, it is ensured that Aerobic Process for Treatment is imitated
Really.
Traditional aeration method is mainly using micro-hole aerator or surface aeration equipment as aerator.But micropore exposes
Gas utensil has easily dirty stifled, and aeration capacity is reduced year by year；Aeration plate is easy to fall off, diaphragm easily tears, and causes oxygenation capacity to decline；Dimension
Frequency repair rate is high, and maintenance when need to empty aeration tank, cause maintenance load greatly etc. drawback.Although surface aeration equipment is easy to
Maintenance, but have the drawbacks such as low, uneven, the muddy water mixed effect difference of aeration of oxygen-transfer efficiency.
Therefore, aerating system is the principal element of restriction sewage aerobic biological treatment development at present.Selection is suitable
Aerator is the important directions for improving sewage aerobic biological treatment capabilities.
Utility model content
To solve the above problems, the utility model provides a kind of simple structure, designs ingenious, high working efficiency new
Microbubble aerobe aeration tank.
A kind of new microbubble aerobe aeration tank of the utility model purpose, including aeration tank body are realized, it is described
The side of aeration tank body is provided with an outer circulation oxygen replenishing equipment, and the two ends of the outer circulation oxygen replenishing equipment are respectively by following outward
Ring oxygenation water inlet pipe and outer circulation oxygenation outlet pipe connection aeration tank body.The aeration tank body interior is provided with a plurality of aeration
Pipe.Some solarization air caps are provided with every aeration tube, one end of every aeration tube is connected and installed in exposure simultaneously
One end of the air inlet pipe of gas pond body exterior side, the other end connection air blower of the air inlet pipe.
A kind of new microbubble aerobe aeration tank described in this patent, using the non-damageable exposure with solarization air cap
Tracheae carries out preliminary oxygenation to aeration tank, while playing stirring action, it is ensured that muddy water mixed effect.External outer circulation is used again
Oxygen replenishing equipment carries out depth oxygenation by sewage outer circulation to aeration tank body, and the process improves sewage using air substitute mode
In dissolved oxygen, dissolution of contaminated water oxygen value after oxygenation is far above conventional aeration method.Finally before the low maintenance rate of aerator
Put, realize the aerobic biodegradation of pollutant.
Brief description of the drawings
Fig. 1 is a kind of structural representation of new microbubble aerobe aeration tank of the present utility model
Specific embodiment
As shown in figure 1, a kind of new microbubble aerobe aeration tank of the present utility model, including aeration tank body 1, institute
The side for stating aeration tank body 1 is provided with an outer circulation oxygen replenishing equipment 3, and the two ends of the outer circulation oxygen replenishing equipment 3 lead to respectively
Cross outer circulation oxygenation water inlet pipe 2 and the connection aeration tank body 1 of outer circulation oxygenation outlet pipe 4.The inside of the aeration tank body 1 is set
There is a plurality of aeration tube 5.Some solarization air caps 6 are provided with every aeration tube 5, one end of every aeration tube 5 is same
When be connected and installed in the outside side of aeration tank body 1 air inlet pipe 7 one end, the air inlet pipe 7 the other end connection air blower
8。
A kind of new microbubble aerobe aeration tank described in this patent, using non-damageable with solarization air cap 6
Aeration tube 5 carries out preliminary oxygenation to aeration tank, while playing stirring action, it is ensured that muddy water mixed effect.Again using external outer
Circulation oxygen replenishing equipment 3 carries out depth oxygenation by sewage outer circulation to aeration tank body 1, and the process is carried using air substitute mode
Dissolved oxygen in sewage high, the dissolution of contaminated water oxygen value after oxygenation is far above conventional aeration method.Finally repaiied in aerator low-dimensional
On the premise of rate, the aerobic biodegradation of pollutant is realized.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, under the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff couple
Various modifications and improvement that technical solutions of the utility model are made, all should fall into the guarantor that claims of the present utility model determine
In the range of shield.
