Abstract
The utility model discloses a microporous aeration disk for sewage treatment. The microporous aeration disk comprises a disk-like aeration disk seat and an aeration disk sheet, wherein the aeration disk sheet is fixedly arranged at the front end of the aeration disk seat, and a gas inlet port is formed at the back end of the aeration disk seat; a plurality of aeration holes are formed on the aeration disk sheet; and the aeration holes are obliquely formed on the aeration disk sheet. The microporous aeration disk has the advantages of uniform gas distribution and high gas-liquid mass transfer efficiency, and can effectively improve sewage treatment and purification effects.
Description
Technical field
The utility model relates to a kind of technical equipment that is used for sewage disposal, relates in particular to the improvement of aerating apparatus structure in the sewage biological treatment system.
Background technology
The biological treatment of sewage is a kind of method of utilizing labile organic compound in the metabolism water of decomposition of microorganism in the waste water, has the advantage that processing power is strong, effluent quality is good.Wherein the active sludge aerobic biological treatment is to utilize the organic method of aerobic degradation in the active sludge, and aerobic microbiological must just can work under the condition that has oxygen to exist, aeration then is that air is fully contacted with sewage, airborne oxygen fully is dissolved in the water, to improve the vitality of aerobic microbiological.
Existing aerating apparatus mostly adopts the tubular type oxygen that exposes to the sun, promptly on oxygen deliverng pipe, have number along its length and arrange the oxygen hole of exposing to the sun, the aeration tube of this structure in actual use, often come with some shortcomings: the skewness of dissolved oxygen in the aeration waste water at first, because the influence of air managed internal resistance in pipeline, and inner air tube constantly overflowing along its length, inner air tube pressure is constantly decayed, even the not enough phenomenon that air can't be overflowed appears pressing in the aeration tube end, cause aeration tube aeration gas on length mass transfer velocity that ducks in drink, lift velocity and all different with the duration of contact of water body, so oxygen concn is obviously different in the same depth of water, directly influence the utilization ratio and the processing efficiency of oxygen.Moreover aeration tube mutually spaced and parallel arrange, rising trace is roughly the straight line that is parallel to each other so the gas that each aeration tube produces ducks in drink, aeration bubble on the same aeration tube is the curtain shape and rises, therefore the agitation force of bubble is not strong, bubble turbulent fluctuation diffusion is not strong, directly influences mass-transfer efficiency and processing efficiency between gas-liquid yet.
The utility model content
At the existing above-mentioned deficiency of prior art, technical problem to be solved in the utility model provides the micro-pore aeration dish that is used for sewage disposal that a kind of gas distribution is even, gas-liquid mass transfer is effective.
In order to solve the problems of the technologies described above, the micro-pore aeration dish that is used for sewage disposal of the present utility model, described micro-pore aeration dish comprises aeration plate seat in the form of annular discs and aeration disc, and this aeration disc is fixedly set in the front end of aeration plate seat, is provided with the air inlet port in the rear end of aeration plate seat; Described aeration disc is provided with some solarization air caps.
After adopting said structure, owing on aeration plate seat in the form of annular discs, be set with the aeration disc that has some solarization air caps, make in aeration plate seat and the formed aeration of the aeration disc chamber that air pressure everywhere is identical, and can not form the attenuation loss of air pressure, also make the aeration bubble in water body, have identical lift velocity and gas-liquid contact time, thereby guaranteed that gas ducks in drink and has higher mass-transfer efficiency, gas distribution is even, the processing efficiency height.Also owing to adopt this structure, solarization air cap on the aeration disc can be circular distribution, the bubble that this micro-pore aeration dish is produced is on the irregular path at water body and rises, produce the intensive agitaion between bubble and the water body, strengthened the turbulent fluctuation diffusion of bubble, it is more even to impel gas to distribute in water body, and gas-liquid mass transfer efficient is higher, can realize the efficient low-consume operation of aeration.This aeration plate has also significantly reduced the aeration tube material use quantity simultaneously.
Preferred implementation of the present utility model, described solarization air cap is arranged on the aeration disc obliquely.This structure has stronger bubble rising diffusion, more helps improving mass-transfer efficiency,
Description of drawings
Below in conjunction with the drawings and specific embodiments the micro-pore aeration dish that the utility model is used for sewage disposal is described in further detail.
Fig. 1 is the main sectional structure synoptic diagram that the utility model is used for a kind of embodiment of micro-pore aeration dish of sewage disposal;

Fig. 3 is a kind of aeration disc structure for amplifying synoptic diagram in the structure shown in Figure 1;
Fig. 4 is an another kind of aeration disc structure for amplifying synoptic diagram in the structure shown in Figure 1.
Among the figure, strengthening rib, 4-aeration plate seat, 5-aeration chamber, 6-air inlet port in 1-aeration disc, 2-solarization air cap, the 3-chamber.
Embodiment
In micro-pore aeration dish as shown in Figure 1 and Figure 2, this aeration plate comprises and is the bucket-shaped aeration plate seat of disk 4 and is the flaky aeration disc 1 of disk, aeration disc 1 is fixedly set in the prosopyle end of aeration plate seat 4 hermetically, and aeration plate seat and aeration disc are that the material continuous casting is in one with plastics in the present embodiment.Between aeration plate seat 4 and aeration disc 1, form aeration chamber 5.Be provided with air inlet port 6 in the rear end of aeration plate seat 4, this air inlet port 6 is connected with air compressor, so that the pressurized air of air compressor is sent in the aeration chamber 5.The flaky aeration disc 1 of disk is provided with some solarization air caps 2, and this solarization air cap 2 is arranged on each concentric(al) circles, and solarization air cap 2 is a cylindrical hole, and its through hole medullary ray all is parallel to the medullary ray of aeration disc 1 and aeration plate seat 4.The aperture of solarization air cap 2 is 0.15mm, can certainly select its aperture in 0.1 ~ 2mm according to working conditionss such as air demand, the air feed depth of waters.
As shown in Figure 3, solarization air cap 2 is arranged on the aeration disc 1 obliquely, it is all space crossed layout of medullary ray of the equal aeration disc 1 of centerline hole of each solarization air cap 2, and being mixed and disorderly inclination each other intersects, this structure has water body when aeration stirs mixing effect preferably, helps oxygen and dissolves in the water body more.Solarization air cap on the aeration disc 12 is a conical bore as shown in Figure 4, and the heavy caliber end of this conical bore is an inlet end, and small-caliber end is the outlet side.
During aeration, pressurized air enters aeration chamber 5 from air inlet port 6, and air pressure is identical everywhere in this chamber.Pressurized air enters the sewage water body from the solarization air cap 2 on the aeration disc 1, realizes gas-liquid mass transfer.
