Description
Technical field:
The utility model relates to technical field of sewage, refers in particular to a kind of Round Sump improved oxidation ditch.
Background technology:
The dominance technology of China municipal sewage plant is the AAO oxidation ditch at present, and AAO is the english abbreviation of Anaerobic-Anoxic-Oxic, and it is the abbreviation of anaerobic-anoxic-aerobic biological denitrification dephosphorization process.This arts demand has anaerobic pond, anoxic pond, Aerobic Pond and settling tank.The AAO oxidation ditch is used widely with stability is high, effluent quality is good with its serviceability.Its weak point of AAO oxidation ditch is because each pond is built separately, has occupied the part land used between the Chi Yuchi, owing to there is not shared body of wall, body of wall need be considered bidirectional stress, and therefore increases the thickness of body of wall.
To the problems referred to above, I propose a kind of Round Sump improved oxidation ditch.The Round Sump improved oxidation ditch is built aerobic+anoxic+anaerobic oxidation ditch, second pond and sludge reflux pump room jointly; And be provided with two Aerobic Ponds; Lay respectively at the both sides in pond, and the sludge reflux pump room is built between oxidation ditch and the second pond, can opens the Aerobic Pond of both sides according to the size of the water yield; When the water yield was big, two Aerobic Ponds moved simultaneously; The water yield hour can be selected to move one of them Aerobic Pond, gives full play to function separately, has promoted processing efficiency greatly, and it is rationalized more.
The utility model content:
The purpose of the utility model is to overcome the prior art weak point, and a kind of Round Sump oxidation ditch is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of Round Sump improved oxidation ditch; Comprise oxidation ditch, second pond and sludge reflux pump room, described oxidation ditch is made up of anaerobic pond, Aerobic Pond, anoxic pond, and described oxidation ditch, backflow pump house and second pond are built jointly; Described anaerobic pond, anoxic pond, sludge reflux pump room and second pond laterally join successively; Described Aerobic Pond has two, is divided into each both sides, pond, is communicated with anaerobic pond and anoxic pond respectively.
Furthermore, in the technique scheme, described anaerobic pond, anoxic pond, sludge reflux pump room close the rectangle form pool body that is separation, one side of the shared rectangle form pool body of described Aerobic Pond; Described second pond is rounded, builds the part circular bay wall of the shared second pond of described Aerobic Pond jointly with the sludge reflux pump room.
Furthermore, in the technique scheme, described anaerobic pond is communicated with sewage inlet, and sewage flows into the Aerobic Pond of both sides after pipeline enters anaerobic pond, and the sewage in the Aerobic Pond is drained in the anoxic pond again.
Furthermore, in the technique scheme, be respectively arranged with the gas collection plate in described anoxic pond, anaerobic pond and the Aerobic Pond.
Furthermore, in the technique scheme, described oxidation ditch available depth is 5 meters; Described second pond available depth is 4 meters.
Have following beneficial effect behind the utility model employing said structure:
1, practices thrift civil engineering costs, reduce floor space.Oxidation ditch, second pond have accounted for very big land area in the water treatment building facility, so corresponding civil engineering costs has also accounted for larger proportion.The Round Sump improved oxidation ditch is built each monomer structures at first phase jointly having guaranteed the following in advance of equal processing efficiency, has reduced construction cost greatly.
2, compact construction is convenient to management.The Round Sump improved oxidation ditch makes it show as compact construction, reasonable in appearance owing to adopt Round Sump; And Sewage Plant is also comparatively convenient when operation management, but certain manpower and materials have been practiced thrift in centralized management, has also shortened the time of response of daily operation maintenance simultaneously.
3, reduce running cost, handiness is high.The oxidation ditch both sides are equipped with Aerobic Pond, and its effect is that the size according to the water yield determines whether that needs all open.When the water yield is big, two standard-sized sheets; When one of unlatching just can be satisfied operating requirement, just only need to open one.So both practiced thrift running cost, and improved processing power again, handiness is very high.

Fig. 1 is the plat of the utility model;
Fig. 2 is the sectional view of the utility model.
Description of reference numerals:
1 anaerobic pond, 2 Aerobic Ponds, 3 anoxic pond
Sludge reflux pump rooms 45 second ponds, 6 gas collection plates
Embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
See Fig. 1-2, a kind of Round Sump improved oxidation ditch comprises oxidation ditch, second pond and sludge reflux pump room, and described oxidation ditch is made up of anaerobic pond 1, Aerobic Pond 2, anoxic pond 3, and described oxidation ditch, second pond 5 and sludge reflux pump room 4 are built jointly.Described anaerobic pond 1, anoxic pond 3, sludge reflux pump room 4 and second pond 5 laterally join successively, and described Aerobic Pond 2 has two, is divided into each both sides, pond, is communicated with anaerobic pond 1 and anoxic pond 3 respectively.
Particularly, described anaerobic pond 1, anoxic pond 3, sludge reflux pump room 4 close the rectangle form pool body that is separation, one side of described Aerobic Pond 2 shared rectangle form pool bodies; Described second pond 5 is rounded, builds the part circular bay wall of described Aerobic Pond 2 shared second ponds 5 jointly with sludge reflux pump room 4.
Anaerobic pond 1 is communicated with sewage inlet, and sewage flows into the Aerobic Pond 2 of both sides after pipeline enters anaerobic pond 1, and the sewage in the Aerobic Pond 2 is drained in the anoxic pond 3 again.Be respectively arranged with gas collection plate 6 in anoxic pond 3, anaerobic pond 1 and the Aerobic Pond 2.
Seeing shown in Figure 1ly, is example with 5000 cubic metres/ton treatment scales, and each pond bay wall height is 5.6 meters, and the peripheral bay wall thickness of whole pond body is 0.3 meter, and the shared bay wall segment thickness of anaerobic pond, anoxic pond, Aerobic Pond and second pond is 0.2 meter.The oxidation ditch available depth is 5 meters, and hydraulic detention time is 12 hours, and the second pond available depth is 4 meters, and hydraulic detention time is 4 hours.During work; Sewage enters into anaerobic pond 1 through pipeline, and anaerobic pond 1 mainly carries out the release of phosphorus, and the concentration of the phosphorus in the sewage is raise; Solvability has both not have by cell and absorbs and make the BOD density loss in the sewage, removes a part of ammonia nitrogen because of cell synthetic in addition.Waste water through after anaerobic pond 1 processing flows in the Aerobic Pond 2 of both sides; In Aerobic Pond 2, organism is by microbial biochemical degraded and continue to descend, organonitrogen by ammonification then by nitrated; NH3N concentration is significantly descended; Increase along with nitrifying process makes the concentration of NO3-N, P is along with the excess ingestion of polyP bacteria also descends, and the sewage that contains NO3-N that nitrifying process produces flows to and carries out the denitrification denitrification in the anoxic pond 3.Second pond 5 settled mud the pump in sludge reflux pump room 4 with under, be back to anaerobic pond 1 through mud return line.When sewage load is big, can use the Aerobic Pond 2 of both sides simultaneously, when WWT two is less, only need to use one of them Aerobic Pond 2, practiced thrift running cost.
Sewage through the processing of the utility model Round Sump improved oxidation ditch; The denitrogenation dephosphorizing identical, the process of degradation of organic substances have been accomplished with traditional AAO oxidation ditch sewage treatment technology; Realized the purpose of purification of waste water; Promoted processing efficiency greatly, reduced and take up an area of cotton knot, it is rationalized more.
Certainly; The above is merely an embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
