Description
Technical field
The utility model relates to sewage treatment area, particularly a kind of sewage disposal device adopting pure oxygen aeration and remaining oxygen reuse.
Background technology
The demand of the mankind to water resources constantly expands, and day by day serious water pollutions nibbles the water resources that can supply consumption in a large number.Along with growth, the industrial expansion of population, water resources is constantly subject to the serious threat of water pollution, water quality deterioration.Unprocessed or process impolitic sewage and be directly discharged in nature and had a strong impact on environmental health, threaten the safe drinking water of people.Sewage treatedly need be purified rear just can being discharged in nature, has become a kind of common recognition.
Membrane bioreactor is a kind of new type water treatment technology combined with biological processing unit by film separation unit.Replace traditional biological treatment technology end second pond with membrane module, in bio-reactor, keep high reactivity sludge concentration, improve biological treatment organic loading, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.Due to its stable effluent quality, high-quality, is therefore used widely in recent years.But general membrane bioreactor, all adopts the offering oxygen way of air aeration, but only have 21% due to the content of oxygen in air, and the solubleness of oxygen in water is lower, therefore must cause sewage treatment facility bulky, build and running cost high.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of can reduce sewage disposal operation cost, improve sewage treating efficiency, the employing pure oxygen aeration of wastewater treatment efficiency and the sewage disposal device of remaining oxygen reuse.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of sewage disposal device adopting pure oxygen aeration and remaining oxygen reuse, is characterized in that: comprise be connected successively by inlet channel grid, settling pit, preliminary sedimentation tank, MBR pond or biochemistry pool, second pond, ozone oxidation pond; Described preliminary sedimentation tank is connected an aerobic sludge digester with bottom second pond by sludge pipe; Pure oxygen aeration pipeline is provided with in described aerobic sludge digester, MBR pond, biochemistry pool.
Preferably, oxygen is connected with in described inlet channel.
Preferably, the pure oxygen of described pure oxygen aeration pipeline adopts the oxygen produced in ozone oxidation pond; Described ozone oxidation pond is connected with pure oxygen aeration pipeline by more than one oxygen reuse pipeline.
Preferably, described remaining oxygen reuse pipeline is provided with the reducing apparatus that is filled with reductive agent.
Preferably, described aerobic sludge digester is also provided with a sludge return pipe, and described sludge return pipe is connected with the inlet channel between preliminary sedimentation tank and MBR or biochemistry pool.
Adopt technique scheme, the sewage disposal device of employing pure oxygen aeration described in the utility model and remaining oxygen reuse, the beneficial effect had is:
1) adopt pure oxygen aeration, when obtaining the aeration effect same with air aeration, less aeration tank volume can be adopted, be conducive to saving floor occupying area, cost of reducing investment outlay; Because aeration rate reduces, less aerating system can be adopted, energy efficient;
2) adopt pure oxygen aeration, stench and VOC(volatile organic compounds can be reduced) distribute, avoid the extra investment cost for preventing stench and VOC from carrying out;
3) adopt pure oxygen aeration, aeration efficiency can be improved, improve the biochemical effects of sewage, reduce the output of active sludge simultaneously, reduce the outer discharge capacity of mud, reduce the cost of specific resistance to filtration;
4) before wastewater disposition, adopt ozone oxidation, process further, and be swift in response to sewage, flow process is simple, does not have secondary pollution problem;
5) the unnecessary oxygen recovery in ozone oxidation pond is in MBR or biochemistry pool, carries out aeration recycling, has saved resource, saves running cost.
Accompanying drawing explanation
Fig. 1 is the sewage disposal device schematic diagram of employing pure oxygen aeration described in the utility model and remaining oxygen reuse.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, adopt the sewage disposal device of pure oxygen aeration and remaining oxygen reuse, comprise be connected successively by inlet channel grid 101, settling pit 102, preliminary sedimentation tank 103, MBR pond (also can be biochemistry pool) 104, second pond 105, ozone oxidation pond 106; Preliminary sedimentation tank 103 is connected an aerobic sludge digester 108 with bottom second pond 105 by sludge pipe 107; Pure oxygen aeration pipeline 109 is provided with in described aerobic sludge digester 108, MBR pond 104; Described ozone oxidation pond 106 is connected with pure oxygen aeration pipeline 109 by more than one oxygen reuse pipeline 110, make the pure oxygen of pure oxygen aeration pipeline 109 adopt the oxygen produced in ozone oxidation pond 106, remaining oxygen reuse pipeline 109 is provided with the reducing apparatus 111 that is filled with reductive agent simultaneously; Aerobic sludge digester 108 is also provided with a sludge return pipe 112, described sludge return pipe 112 is connected with the inlet channel between preliminary sedimentation tank 103 and MBR104.
During concrete use, in the inlet channel of sewage, oxygen can also be filled with, by the generation of foul smell in Oxygen control sewage network, improve the smell of sewage; The utility model is by MBR or biochemical reaction tank simultaneously, adopts pure oxygen aeration, replaces traditional air aeration.Under same aeration rate, higher dissolved oxygen can be obtained, tolerate higher sludge concentration and sludge loading.And be, when obtaining the aeration effect same with air aeration, less aeration tank volume can be adopted, be conducive to saving floor space, cost of reducing investment outlay; Less aerating system can be adopted, energy efficient; In aerobic sludge digester, be filled with purity oxygen simultaneously, adopt the aerobic sludge digestion of pure oxygen, improve the digestive efficiency of mud.When reaching equal digestion effect, reducing digester volume, reducing cost of investment.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
