Abstract
Name of the present utility model is called the aerobic Sewage treatment systems of low aeration, relate to sewage treatment area, be specifically related to the aeration process in a kind of sewage aerobic process, main purpose is to provide and a kind ofly extends the residence time of air in water to reduce the aerating system of aeration rate, and then reduces energy consumption and working cost.Native system says that aeration tank is divided into A, B two regions, covering seepy material under the liquid level on top, A district and form aeroseal floor, is oxygen-rich area below sealing ply, in hollow state, be hung with a large amount of fillers, increase the contact area of air and water, and have certain intervals, be convenient to air flowing, air enters from top, oxygen enrichment packing area, get rid of from bottom, substantially increase the residence time, and then realize the reduction of aeration rate.Two top, districts and top communicate, and bottom and bottom communicate, and make the water body in aeration tank can form self-circulation at A, B two between district, B district arranges intake-outlet, for upgrading water body.
Description
Technical field
The utility model relates to sewage treatment area, is specifically related to the aeration process in a kind of sewage aerobic process.
Background technology
Along with the deterioration of China's integrated environment quality, government, enterprise and society be more and more attaching importance to environmental protection work also, and wherein sewage disposal is one of important content of environmental improvement.In sewage treatment technology, aerobic method and anaerobic process are most important two kinds for the treatment of process, greatly can be cut down the pollutent in sewage by organic assembling.At present, in the aerobic treatment process of sewage, the technology generally adopted has traditional activated sludge process, SBR method, MBR method etc.Aerobic processes exactly by blasting air to realize in sewage, for the growth of aerobic microbiological creates conditions.
The common ground of this mode is that air enters water body from bottom, and directly floating is overflowed from the water surface, it is very short that this mode causes the residence time of air in water body, therefore in order to ensure the abundance of oxygen in water body, need ceaselessly in water, to blast a large amount of air always, not only cause the energy consumption of gas blower very huge, also result in the huge waste of the energy simultaneously.And in the energy consumption of sewage work, gas blower then occupies the overwhelming majority, if the energy consumption of aerating system can be reduced, also just substantially achieve the reduction of sewage disposal running cost, and this also becomes a problem of the comparison headache of sewage work.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can extends the residence time of air in water thus reduce the aerating system of aeration rate.In order to achieve the above object, the technical scheme that the utility model adopts is: aeration tank is arranged A, B two regions, the top in two regions is connected with top, and bottom is connected with bottom.Position under the liquid level on wherein top, A district covers seepy material, as aeroseal layer; Be oxygen-rich area below sealing ply, in hollow state, be hung with mass filler, for increasing the contact area of liquid level and air, improving oxygen enrichment efficiency, is the agent structure of oxygen enrichment in water, filler has good water-absorbent, and the water from pervious bed oozes can flow downward along filler easily; There is certain space between filler, be convenient to air flowing; Top in oxygen-rich layer district, be provided with inlet pipe near pool wall side, bottom is provided with production well near the side in B district, and air flows from top to bottom, enters bottom B district, and finally overflows from the liquid level in B district; B district is provided with a large amount of fillers, uses in order to microorganism growth biofilm; Water in aeration tank forms inner self-circulation, from top, A district to falling into bottom, and enters bottom B district bottom A district, then enters top, A district from top, B district; Both sides, B district are provided with intake-outlet, for upgrading the water body in pond.
The utility model changes the mode of tradition from bottom aeration completely, its beneficial effect substantially prolongs the residence time of air in water, thus greatly can reduce aeration rate, and then reduce gas blower energy consumption, save a large amount of working cost, reduce cost of water treatment.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model plane structure chart.
Accompanying drawing 2 is this utility model 1-1 sectional view.
Accompanying drawing 3 is this utility model 2-2 sectional view.
Numbering 1-water inlet pipe in figure, 2-aeration tube, 3-contact filler, 4-contact filler support, 5-top water distribution layer, 6-permeable layer, 7-oxygen enrichment filler support, 8-inlet pipe, 9-oxygen enrichment filler, 10-underdrain layer, 11-bottom water distributing pore, 12-water outlet.
Embodiment
Sewage is first by 1(water inlet pipe) enter into bottom B district, 5(top water distribution layer is entered into from upper flowing) by lower, A, B two the top water distribution layer in district communicate, sewage is in 5(top water distribution layer) in flow to A district by B district, due to 6(permeable layer) there is certain coefficient of permeability, therefore sewage can pass through 6(permeable layer with certain flow) and flow to 9(oxygen enrichment filler uniformly) on, and drop onto 10(underdrain layer downwards) in, and by water distributing pore bottom 11() again flow in B district.
Air is by 8(inlet pipe) from the 9(oxygen enrichment filler of side, A district) top, flow downward.Owing to there is space between filler, contact with air when sewage flows through from filling surface and realize water body oxygen enrichment, then air is from 9(oxygen enrichment filler) bottom 2(aeration tube) flow out into B district, at this, secondary oxygen enrichment is carried out to the water body in B district, and finally overflow water from the water surface, and system final outflow water is by 12(water outlet) discharge.
Claims (6)
1. the aerobic Sewage treatment systems of low aeration, structure is divided into two portions, i.e. A district and B district, and it is characterized in that A divides into water distribution layer, permeable layer, oxygen enrichment filler and underdrain layer, B district mainly comprises aeration tube and contacts filler.
2. the aerobic Sewage treatment systems of low aeration according to claim 1, is characterized in that: A district top water distribution layer is all connected with B district with underdrain floor, ensure A, B two district water body realize circulation.
3. the aerobic Sewage treatment systems of low aeration according to claim 1, it is characterized in that: permeable layer is made up of the good material of certain thickness water-absorbent, by changing the modes such as the material of permeable layer material or thickness, the coefficient of permeability of permeable layer can be changed, and then controlling sections crosses water flux, permeable layer can ensure that sewage flows downward on the one hand and flow on oxygen enrichment filler, also plays the effect of sealing on the other hand, air can not upwards be overflowed.
4. the aerobic Sewage treatment systems of low aeration according to claim 1, is characterized in that: oxygen enrichment filler has certain water-absorbent, ensures that the sewage of permeable layer can flow downward smoothly; Filler distribution marshalling, between there is certain space, be convenient to air flowing; The effect of filler is as microbial growth provides attachment point, and the contact area increasing water body and air improves oxygen enrichment efficiency.
