Description
Technical field
The utility model relates to a kind of deep well aeration equipment, belongs to technical field of sewage.
Background technology
The waste water aerobic biological treatment is constantly to charge into (compression) air in the aeration tank that aerobic microbiological is arranged, and oxygen is dissolved in the waste water, makes good use of oxygen animalcule and decomposes pollutants in waste water matter.Because the working cost that aeration is handled is mainly power consumption, so improve the transfer efficiency of oxygen in the aeration process air, increase the unit power consumption oxygenation capacity is the emphasis of aerator and technological development always.The transfer efficiency of tradition air blast aeration system oxygen has only 5-15%, and a large amount of power of gas blower is wasted.
Deep well aeration is a kind of activated sludge process wastewater treatment new technology that development in recent years is got up, because special deep-well equipment structure, produced the pressure that is higher than the normal pressure several times in waste water treater inside, oxygen fully is dissolved under this condition in the water, for the aerobic degradation organic contamination factor provides competent oxygen branch.The deep well aeration method has improved the transfer efficiency of oxygen greatly, is a kind of very promising high-efficiency low energy consumption biological wastewater treatment technology.
Deep well aeration effectively utilizes the significant depth of the well that exposes to the sun deeply, carries out the deep water aeration.Underwater solubleness of oxygen and pressure are inversely proportional to, and the absolute pressure that the depth of water is located at H (m) can be with following The Representation Equation, units MPa, Pb=P0+0.01H.10 meters of the every increases of the depth of water, then pressure doubles.The deep well aeration method depth of water can reach 50-150 rice usually, and hydrostaticpressure is surperficial 5-15 times so under water.Under huge pressure effect, the degree of depth surpasses 100 meters the shaft bottom of exposing to the sun deeply and can not see bubble, all dissolves in water quality, dissolved oxygen concentration up to 100mg/l about.Owing to the aeration well depth, bubble is long with the water contact lysis time in well in addition, and therefore, the utilization ratio of deep well aeration method oxygen is up to 60%～90%.At present, American-European countries has been widely used in this technology and has handled wastewater from chemical industry, pharmacy waste water, food processing wastewater, paper waste and composite waste etc.But this traditional aeration process in deep well exists the bigger technical problem of energy consumption.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of and can addresses the above problem, and has the deep well aeration device of higher energy utilization rate.
For achieving the above object, the utility model provides following technical scheme:
The deep well aeration device comprises housing, is positioned at the inverted draw cut of device upper end and is positioned at the aeration tube at middle part that the aeration tube top is an inlet mouth, and the aeration tube lower end down extends to form and is downtake, and the terminal bore of downtake dwindles earlier to enlarge again and forms nozzle configuration.On the horizontal direction of aeration tube upper end, be formed with a pipeline that is communicated with aeration tube, constitute the air-flow inner cycle channel.
According to the further setting to technique scheme, the outer end of air-flow inner cycle channel is formed with an airflow inlet.The outside that inverted draw cut is positioned at aeration tube and air-flow inner cycle channel forms a housing, and both all are placed in one, and inverted draw cut is near being formed with an opening near the import of air-flow inner cycle channel.
The utility model is formed with a pipeline that is communicated with aeration tube on the horizontal direction of aeration tube upper end, form the air-flow inner cycle channel, has solved the bigger problem of existing aeration process in deep well energy consumption.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of deep well aeration equipment downtake.
Embodiment
As shown in Figure 1: a kind of preferred embodiment deep well aeration device 10 of the present utility model, comprise housing 3, be positioned at the inverted draw cut 2 of device upper end and be positioned at the aeration tube 1 at middle part, the aeration tube top is an inlet mouth 5, the aeration tube lower end down extends to form and is downtake 4, and downtake 4 terminal bores dwindle earlier to enlarge again and form nozzle configuration.On the horizontal direction of aeration tube upper end, be formed with a pipeline that is communicated with aeration tube 6, form the air-flow inner cycle channel.The outer end of air-flow inner cycle channel 6 is formed with an airflow inlet 7.The outside that inverted draw cut is positioned at aeration tube and air-flow inner cycle channel forms a housing, and both all are placed in one, and inverted draw cut is near being formed with an opening 19 near the import of air-flow inner cycle channel.
Designed a side direction inner cycle channel at the deep well aeration pipe, prolonged the residence time for the treatment of water, realized the energy-conservation degassing behind the aeration, compared with traditional vacuum degasser and saved energy at inverted draw cut.
Mixing liquid after aeration is handled, need be with the water sepn after active sludge and the processing, usually air content may be very high in the water outlet, when gas adsorption is too much on the active sludge, because proportion reduces, sludge settling is poor, and mud just loses with current with the floating water surface of going up of gas, and mud can't be precipitated in second pond.So not only influence effluent quality, and, make that activated sludge concentration constantly reduces in the mixed solution of aeration tank, when serious even destroy whole biochemical treatment system because mud runs off in a large number.Common de-gassing vessel generally adopts the method for mechanical stirring or vacuumize degassing, and energy expenditure is bigger.
We find to prevent the mud come-up by the way that increases quantity of reflux that when the water body bottom deep-well was back to inverted draw cut, pressure obtained discharging, gas overflows liquid level thereupon, along with the prolongation of time, gas content reduces gradually in the liquid, and most mud just begins to have precipitated.Therefore, we have added an inner cycle channel in the side direction of aeration tube, its side links to each other with aeration tube, the other end is import, import is near the sidewall of inverted draw cut and keep suitable clearance distance, and also do not outgas fully sedimentary mud and mixed solution of part can reflux once more by this pipeline and enter aeration tube.This inner cycle channel has been arranged, equaled to prolong the residence time for the treatment of water, improved the removal effect of underwater bubble at inverted draw cut.
The advantage of the innovation design is:
1, the active sludge loss is few
Because designed exclusive inner cycle channel, most active sludge can enter the aeration well once more by it, and activated sludge concentration does not reduce, and is beneficial for the processing of pollutent.When if mud too much need efflux, because the mud degassing time is abundant, fully precipitate at second pond, mud removes by filter easily, and effluent quality is secure.
2, consumed energy is low
Water after the processing repeatedly circulates through inner cycle channel, and fully the degassing does not need specific installation, outgases as vacuum pump or stirring, has reduced the equipment power consumption.
