Technical field
The present invention relates to sewage treatment area, be specially a kind of waste disposal plant with pressure equaliser.
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 waste disposal plant with pressure equaliser, and to solve oxygen deficiency in the waste disposal plant aeration process, the system inner air pressure is non-constant, 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 waste disposal plant with pressure equaliser, 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 by tracheae priority and air valve (20), gas-holder (19), gas blower (10) is connected with inlet pipe (9), 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) internal system pressure is relatively constant, and aeration efficiency is largely increased;
3) gas collector is arranged above aeration tank, reduce the pollution to atmosphere.
