Description

A kind of aerator of MBR aeration

Technical field

The utility model relates to technical field of sewage treatment equipment, more particularly, to a kind of aerator of MBR aeration.

Background technique

MBR membrane Bio-reactor Technology is that membrane separation technique introduction is given up into aquatic organism processing system, using UF membrane with Biologic treating technique realizes the treatment process of wastewater efficient purification.It has effluent quality good stable, occupied area small, active The advantages such as sludge concentration is high, surplus sludge volume is few, easy automation control, easy to operate, processing cost is low.

Current curtain hollow-fibre membrane MBR has found broad application in sewage treatment field, improves the stabilization of membranous system Property, extend the cleaning frequency be the key that curtain hollow fibre membrane systems operating cost is effectively reduced.Existing perforated tube aeration There is aeration unevenly in device, stability is poor, and aeration tube easily blocks, and scrub effect is poor, and energy consumption is high, seriously affect film group device Using effect and service life, it is therefore desirable to research be more suitable curtain type membrane scouring aerator, guarantee film wire jitter effect Appropriateness, uniform, extension film group device cleaning frequency, reduction energy consumption.

Utility model content

The purpose of this utility model is intended to overcome the shortcomings of the prior art, and it is uniform and stable to provide a kind of aeration The aerator of MBR aeration.

In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:

A kind of aerator of MBR aeration, including aeration tank and two be respectively arranged at aeration tank both ends aeration it is curved Head；The aeration tank is in the rectangular-shape of open at its lower end, and left and right ends are respectively arranged with air inlet pipe, the two aeration elbows point Not Tong Guo locking nut connect with two air inlet pipe；The front and rear sides of the aeration tank are respectively provided with contour solarization air cap group；The exposure Stomata group includes multiple solarization air caps being placed equidistant with；The solarization air cap group of the front and rear sides of the aeration tank shifts to install.

Preferably, the groove of connection is set on the outer wall of the air inlet pipe.

Preferably, the aperture of the air inlet pipe is 18-38mm.

Preferably, the length of the aeration tank is 300-1200mm.

Preferably, the aperture of the solarization air cap is 4-φ of φ 10mm, and the spacing between solarization air cap is 100-200mm.

Compared with prior art, the utility model has the advantages that

1, when the utility model is used, gas enters aeration tank simultaneously from two aeration elbows, and enter after aeration tank from The solarization air cap rule of same absolute altitude is discharged, and allows for being aerated so more uniform, extends the cleaning frequency of film product, guarantees that film is long Phase stable operation.

2, the solarization air cap of the utility model is that regular misplace in aeration tank two sides is arranged, and thus forms film wire two sides The rising bubble being staggered improves film wire and cleans efficiency and reduce solarization air cap to form film wire scouring straggly all around Quantity thereby reduces energy consumption.

3, the aeration tank of the utility model unenclosed construction that Open Side Down, gas is under the action of buoyancy from top in slot Portion is uniformly overflowed after slowly filling to solarization air cap, allows for forming stable air pressure in entire aeration tank in this way, to avoid exposing Air-hole blockage and exhaust are uneven.Gas from the aeration elbows of two sides simultaneously, same amount, with being pressed into aeration tank, in aeration tank often Pressure uniformly release, in this way it is avoided that the problems such as gas leakage fractures caused by aeration tank is washed away because of vibration.

4, the aeration tank of the utility model using when be arranged in parallel in the positive bottom of monolithic film group device, gas is from two panels film wire Centre is flowed from the bottom up, and is staggeredly arranged between two groups of aeration tanks, ensure that unilateral gas cleans both sides film wire, and formed Sinusoid is cleaned, and is greatly lowered aeration quantity in this way and is improved scrub effect.

5, the utility model has compared perforated pipe aerating regulation, and the utility model trembles that film effect is more preferable, and energy consumption is lower.

6, the utility model clean and maintenance is convenient, has longer service life, can significantly reduce its use cost.
