Description

There is the waste disposal plant that sludge methane is collected
Technical field
The present invention relates to sewage treatment area, be specially a kind of waste disposal plant that sludge methane is collected that has.
Background technology
In municipal sewage treatment process, Wastewater Treated by Activated Sludge Process is a kind of common processing mode.Its aeration tank is rectangle, and 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 discharges from tail end, 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, and therefore 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 tail end dissolved oxygen, generally in superfluous state, is guaranteeing in the normal situation of end dissolved oxygen, dissolved oxygen content possibility deficiency in leading portion mixed solution.
On the other hand, the gas producing in its aeration process can produce pollution again to atmosphere, is directly discharged in atmosphere, is unfavorable for environment protection, easily causes environmental pollution, and meanwhile, the mud of generation, because water content is large, is difficult for following process.
Summary of the invention
The application's object is to provide a kind of waste disposal plant that sludge methane is collected that has, and to solve oxygen deficiency in waste disposal plant aeration process, sludge moisture content is large, and the problem of the gas distributing to topsoil.
In order to achieve the above object, the present invention is by the following technical solutions:
A kind of waste disposal plant with sludge methane collection, comprise aeration tank (2), settling tank (4), collecting hood (14) and filter material (16), it is characterized in that: described one end, aeration tank (2) is connected with former water inlet (1), the other end passed through water pipe (3) and linked together with settling tank (4), described top, aeration tank (2) is provided with gas extractor, described bottom, 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 multiple sub-tracheaes (12) in the inside of distribution piping (11), each sub-tracheae (12) is all provided with a vapor pipe (13), the bottom of described settling tank (4) is connected with mud return line (6), mud return line (6) links together with former water inlet (1) again, the bottom of described mud return line (6) is provided with excess sludge discharge pipe (8), below excess sludge discharge pipe (8), be provided with concentration basin (19), concentration basin (19) is connected with digester (20) below, on digester (20), be connected with methane-generating pit (21).
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).
The present invention has the following advantages:
1) there is air-blast device, can guarantee oxygen abundance in aeration tank;
2) above aeration tank, there is gas collector, reduce the pollution to atmosphere;
3) mud system being produced carries out thickening, facilitates subsequent disposal.
Accompanying drawing explanation
Fig. 1 has the waste disposal plant structural representation that sludge methane is collected
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; Concentration basin 19; Digester 20; Methane-generating pit 21.
Embodiment
As shown in Figure 1, the waste disposal plant with sludge methane collection 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), in settling tank (4), process water later and enter into cavity filter (7) by rising pipe (5), then be discharged into the external world.
Active sludge in settling tank (4) precipitates, a part enters into aeration tank (2) again by mud return line (6), another part is rejected in concentration basin (19) by excess sludge discharge pipe (8), by concentration basin (19), mud is concentrated, be transported to again in digester (20) and dewater, remove moisture, the biogas producing in digester (20) is transported in methane-generating pit (21) simultaneously, then sludge silt in digester (20) can be used as the raw material of producing fertilizer, or carry out harmless processing and carry out landfill.
In order to ensure aeration tank (2) interior oxygen abundance, in the bottom of aeration tank (2), be provided with the tracheae being connected with inlet pipe (9) and gas blower (10), air enters into the distribution piping (11) of bottom, aeration tank (2) by inlet pipe (9), gas blower (10), be assigned in sub-tracheae (12) by distribution piping (11) again, finally be discharged in aeration tank (2) by vapor pipe (13), react with the sewage in aeration tank (2), sewage is processed.
