Abstract
The utility model discloses a micro-nano aeration tank. The micro-nano aeration tank comprises a tank body (1), a water inlet (2), self-priming pumps (3), compressed air pipes (4), jet devices (5), main pipes (6), branch pipes (7), micro-nano aerators (8) and a water outlet (9), wherein pumped by the self-priming pumps (3), the sewage flows through the jet devices (5), sucks gases in the compressed air pipes (4) as the cross sectional area of the pipeline is reduced, the flow velocity is increased and negative pressure is generated, and flows back to gas-water mixing chambers (10) under the action of gas-water circulating pipelines (9); under the centrifugal action, bubbles are broken into tiny nano bubbles, then enter the main pipes (6) to be fully mixed, pass through the branch pipes (7) and are finally sprayed of the micro-nano aerators (8). The micro-nano aeration tank has the advantages that the micro-nano aeration tank is reasonable in design; the dissolved oxygen (DO) of the feed water is smaller than 0.3mg/L; through the micro-nano aeration tank, the DO is increased to 3.5-5mg/L, so that the utilization rate of oxygen is increased, the oxygenating efficiency is high, and the micro-nano aeration tank is convenient to popularize and apply.
Description
Technical field
The utility model relates to the treatment unit of waste water, particularly micro-nano aeration tank.
Background technology
Along with the increase of urban population and the development of industrial and agricultural production, the quantity discharged of industrial sewage and city domestic water is also increasing day by day, considerably beyond the self-purification capacity of environment, make water pollution day by day serious, and the various places that almost spread all over the country, therefore, people also pollute at the elimination water of making great efforts, and various sewage water treatment methods and technique are pressed and also arisen at the historic moment.
At present, adopt bio-aeration pool that sewage is processed and is widely used, bio-aeration pool combines active sludge sewage is processed with microbial film.In active sludge, contain and take organism and be the inoculating microbe of food, this inoculating microbe need to provide oxygen, is generally suspension growth in artificial environment, under the environment of oxygen, this inoculating microbe, by organic substance decomposing, makes inorganicization of organism, thereby reaches the object of purifying water body.But this method need to provide a large amount of oxygen to microorganism, traditional bio-aeration pipe adopts method oxygen supply from top to bottom, at the bottom of making oxygen not arrive pond, and causes the microorganism of bottom for hypoxgia.Although and employing method for supplying oxygen has from bottom to top solved the oxygen－deficient problem in bottom, pond, oxygenous bubble rises rapidly from bottom, the time resting in pond is too short, has greatly reduced the utilization ratio of oxygen.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, provides a kind of reasonable in design, utilization ratio of greatly having improved oxygen simple in structure, the micro-nano aeration tank that oxygen-transfer efficiency is high.
The technical solution adopted in the utility model is: micro-nano aeration tank, comprises that pond body (1), water-in (2), vacuum primingpump (3), compressed air pipe (4), ejector (5), main (6), arm (7), micro-nano aeration head (8) and water outlet (9) form; Described vacuum primingpump (3) is connected with ejector (5), ejector (5) middle part is connected with a compressed air pipe (4), outlet is connected with main (6), at main (6) below connecting branch (7) and micro-nano aeration head (8).
Sewage in the described aeration tank ejector (5) of flowing through under vacuum primingpump (3) decimate action, because pipeline cross-sectional area tightens suddenly, flow velocity increases, produce negative pressure, suck gas in compressed air pipe (4), and fully mix, under air water circulating line (9) effect, be back to mixing wastewater with air chamber (10), do under the action of the centrifugal cutting movement, bubble is ground into small nano bubble, fully mix entering main (6), through arm (7), finally from micro-nano aeration head (8), spray.
The injection of mutually staggering of described main (6) and arm (7).
Described main (6) distribution mode is close, favourable so even by water flow pressure after front dredging.
Application method of the present utility model is: the sewage ejector (5) of flowing through under vacuum primingpump (3) decimate action, because pipeline cross-sectional area tightens suddenly, flow velocity increases, produce negative pressure, suck gas in compressed air pipe (4), and fully mix, under air water circulating line (9) effect, be back to mixing wastewater with air chamber (10), do under the action of the centrifugal cutting movement, bubble is ground into small nano bubble, fully mix entering main (6), through arm (7), finally from micro-nano aeration head (8), spray.The dissolved oxygen DO of water inlet is less than 0.3mg/L, and through micro-nano aeration tank, dissolved oxygen DO brings up to 3.5～5mg/L, has greatly improved the utilization ratio of oxygen, and oxygen-transfer efficiency is high.
The utility model has the advantage of: the utility model is reasonable in design, airborne oxygen and sewage are fully contacted and reach better oxidation effect, greatly improved the utilization ratio of oxygen, save energy, reduces cost of sewage disposal, easy to utilize.
