The utility model relates to an aerated collection type sewage treatment device comprising an aeration tank (2), a sedimentation tank (4), a collecting hood (14) and a filter material (16). The aerated collection type sewage treatment device is characterized in that one end of the aeration tank (2) is connected with a raw water inlet (1), and the other end of the aeration tank (2) is connected with the sedimentation tank (4) through a water pipe (3); a gas collecting device is arranged above the aeration tank (2); the bottom of the aeration tank (2) is provided with a distribution pipe (11); the distribution pipe (11) is connected with a blast blower (10) and an air inlet pipe (9) through an air pipe and is internally provided with a plurality of sub air pipes (12); each sub air pipe (12) is provided with an air outlet pipe (13). The aerated collection type sewage treatment device is provided with a blower device to ensure that oxygen in the aeration tank is insufficient, and the gas collecting device is arranged above the aeration tank so as to reduce the atmospheric pollution.
Description
Technical field
The present invention relates to sewage treatment area, be specially a kind of aeration collection type waste disposal plant.
Background technology
In the municipal sewage treatment process, Wastewater Treated by Activated Sludge Process is a kind of common processing mode.Its aeration tank is rectangle, and the mixed solution fluidised form is pulling flow type, and sewage head end from aeration tank together with returned sluge enters, under the promotion of aeration and hydraulics, mixed solution balancedly flows backward, finally from tail end, discharges, and leading portion liquid stream and back segment liquid stream do not mix.Waste strength is downward trend gradually from Shou Zhi pond, pond tail, so the impellent of organic matter degradation reaction is larger, and efficiency is higher.The aerobic rate in aeration tank is long along pond to be reduced gradually, and the tail end dissolved oxygen, generally in superfluous state, is guaranteeing in the normal situation of end dissolved oxygen, dissolved oxygen content possibility deficiency in the leading portion mixed solution.
On the other hand, the gas produced in its aeration process can produce pollution again to atmosphere, directly is discharged in atmosphere, is unfavorable for environment protection, easily causes environmental pollution.
Summary of the invention
The application's purpose is to provide a kind of aeration collection type waste disposal plant, and to solve oxygen deficiency in the waste disposal plant aeration process, and the gas distributed is to the problem of topsoil.
In order to achieve the above object, the present invention is by the following technical solutions:
A kind of aeration collection type waste disposal plant, comprise aeration tank (2), settling tank (4), collecting hood (14) and filter material (16), it is characterized in that: described aeration tank (2) one ends are connected with former water inlet (1), the other end passed through water pipe (3) and linked together with settling tank (4), top, described aeration tank (2) is provided with gas extractor, bottom, described aeration tank (2) is provided with distribution piping (11), distribution piping (11) is connected with inlet pipe (9) with gas blower (10) by tracheae, be provided with a plurality of sub-tracheaes (12) in the inside of distribution piping (11), each sub-tracheae (12) all is provided with a vapor pipe (13).
Further, described gas extractor comprises collecting hood (14), effuser (15) and gas-filtering device.
Further, described gas-filtering device comprises filter material (16), and, between the buffering of filter material (16) top (17), between described buffering, (17) top is provided with escape pipe (18).
Further, described settling tank (4) links together by rising pipe (5) and cavity filter (7).
Further, the bottom of described settling tank (4) is connected with mud return line (6), and mud return line (6) links together with former water inlet (1) again.
Further, the bottom of described mud return line (6) is provided with excess sludge discharge pipe (8).
The present invention has the following advantages:
1) there is air-blast device, can guarantee oxygen abundance in aeration tank;
2) gas collector is arranged above aeration tank, reduce the pollution to atmosphere.
The accompanying drawing explanation
Fig. 1 aeration collection type waste disposal plant structural representation
Former water inlet 1; Aeration tank 2; Cross water pipe 3; Settling tank 4; Rising pipe 5; Mud return line 6; Cavity filter 7; Excess sludge discharge pipe 8; Inlet pipe 9; Gas blower 10; Distribution piping 11; Sub-tracheae 12; Vapor pipe 13; Collecting hood 14; Effuser 15; Filter material 16; Between buffering 17; Escape pipe 18.
Embodiment
As shown in Figure 1, aeration collection type waste disposal plant mainly comprises aeration tank (2) and settling tank (4), and collecting hood (14) and filter material (16), former water enters into aeration tank (2) from former water inlet (1), aeration tank (2) was passed through water pipe (3) and was linked together with settling tank (4), process water later in settling tank (4) and enter into cavity filter (7) by rising pipe (5), then be discharged into the external world.
Active sludge in settling tank (4) precipitates, and a part enters into aeration tank (2) again by mud return line (6), and another part is rejected to outside waste disposal plant by excess sludge discharge pipe (8).
In order to ensure aeration tank (2) interior oxygen abundance, be provided with the tracheae be connected with gas blower (10) with inlet pipe (9) in the bottom of aeration tank (2), air enters into the distribution piping (11) of bottom, aeration tank (2) by inlet pipe (9), gas blower (10), by distribution piping (11), be assigned in sub-tracheae (12) again, finally by vapor pipe (13), be discharged in aeration tank (2), react with the sewage in aeration tank (2), sewage is processed.
In aeration tank, (2) top is provided with gas extractor, and this gas extractor comprises collecting hood (14), effuser (15) and gas-filtering device.This gas-filtering device comprises filter material (16), and, between the buffering of filter material (16) top (17), between described buffering, (17) top is provided with escape pipe (18).
Although top some specific embodiments of having given an example illustrate and describe the present invention, and do not mean that the present invention only is confined to wherein each kind of details.On the contrary, can not depart from the present invention in the category that is equivalent to claims and scope and on various details, make to spirit various modifications.The part of not writing exactly in specification sheets is general knowledge known in this field, states in detail.
