To municipal wastewater is typically denitrogenated using bioanalysis dephosphorization at present.
Conventional oxidation ditch technique is a kind of common technique of Treating Municipal Sewage, is that one kind of traditional activated sludge process is changed
It is good.Its technical process is：Sewage enters from one end of irrigation canals and ditches, by the circulation of up to a hundred times, overflow outflow.In the difference of oxidation ditch
Region, anoxic zone and oxygen-rich area are formd, realize dephosphorization effect.But conventional oxidation ditch is due to lacking carbon source, it is impossible to provides poly-
Enough carbon required for phosphorus bacterium, oxidation ditch process lack the ability of dephosphorization.The handling process of improved oxidation ditch is provided with single
Only anaerobic zone and anoxic zone, makes polyP bacteria possess the anaerobic environment and carbon source released needed for phosphorus, and the dephosphorization ability of system is carried
Rise, but be completely independent between the regional of improvement oxidation ditch, be unfavorable for circulation of the sewage between regional.
Utility model content
In view of this, the purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of for sewage disposal
Integrated reacting pond.
Technical scheme used by the utility model is：
A kind of integrated reacting pond for sewage disposal, including anaerobic pond, anoxic pond and the Aerobic Pond set gradually, institute

It is equipped with water passage and inside is provided with submersible agitator；The one-level anaerobic pond is connected with mud pipe and sparge pipe；It is described
Water passage is provided between anoxic pond and secondary anaerobic pond；Water passage is provided between the Aerobic Pond and anoxic pond and is returned
Circulation road；Vent line is provided with the Aerobic Pond, the aeration tube that vent line is set with Aerobic Pond bottom of pond portion is connected.
Preferably, for the anoxic pond to be longitudinally arranged, Aerobic Pond is lateral arrangement.
Preferably, two undercurrent agitators are provided with the anoxic pond, four undercurrent agitators are provided with Aerobic Pond.
Preferably, one end of the Aerobic Pond is provided with the outlet pipe for being used for that sewage to be discharged into sedimentation basin.
Preferably, the anaerobic pond, anoxic pond and Aerobic Pond pond depth are 4-6m, volume ratio 1：3：8.
Preferably, the anoxic pond and Aerobic Pond are oxidation ditch pattern, are divided into septal fossula and outer fissure.
The beneficial effects of the utility model are：
The principle that a kind of integrated reacting pond for sewage disposal of the present utility model is denitrogenated according to dephosphorization, by oxidation ditch
Technique is combined with anaerobism, anoxic, aerobic technological process, construct integration reaction tank, make it have it is relatively independent rather than
Completely self-contained anaerobism, anoxic, aerobic zone, not only solve conventional oxidation ditch and lack asking for dephosphorization ability due to lacking carbon source
Topic, also eliminate the pump required for improvement oxidation ditch backflow sewage.
The utility model combination sewage sludge reflux technique, it had both had the outward appearance and operation characteristic of oxidation ditch, had again
Good denitrogenation dephosphorizing ability；Integrated reaction tank resistance to overload shock of the present utility model and reduce equipment investment, handle
Structures are compact, effectively saved cost.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1-Figure 3, a kind of integrated reacting pond for sewage disposal, including set gradually anaerobic pond, lack
Oxygen pond 3 and Aerobic Pond 4, anaerobic pond are the one-level anaerobic pond 1 and secondary anaerobic pond 2 being set up in parallel, and the bottom of one-level anaerobic pond 1 connects
Have and match somebody with somebody mud pipe 6 and sparge pipe 7, water passage 8 is provided between one-level anaerobic pond 1 and secondary anaerobic pond 2 and bottom is both provided with
Submersible agitator 9；Water passage 8 is provided between secondary anaerobic pond 2 and anoxic pond 3, is set between anoxic pond 3 and Aerobic Pond 4
There are water passage 8 and return flow line 11；Two undercurrent agitators 5 are provided with anoxic pond 3, are stirred in Aerobic Pond 4 provided with four undercurrents
Device 5 is mixed, is provided with vent line 12 in Aerobic Pond 4, the aeration tube 13 that vent line 12 is set with the bottom of pond portion of Aerobic Pond 4 is connected, good
