Abstract
The utility model discloses an aeration disc and an aeration device for the water pollution regulation of riverways. The aeration disc comprises a support, at least three annular hoses which are fixed to the support and are in the same plane and a gas transmission pipe communicated with all annular hoses, wherein aeration holes are formed on the pipe walls of the annular hoses. When the aeration disc oxygenates to water bodies by aeration, gas is diffused at the periphery of the aeration disc to form a vortex, and convection is formed between an upper layer of water bodies and a lower layer of water bodies, so that the reoxygenation of the water bodies is accelerated, and energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of aerating apparatus, relates in particular to the aeration plate and the aerating apparatus of a kind of river course water pollution control.
Background technology
Find from the clarke of Britain in 1912 and Gage, can produce mud the long-time aeration of sewage, simultaneously water quality be improved significantly, activated sludge process just and wastewater treatment be closely linked.The U.S. has 18000 of waste water treatment plants approximately, and wherein 84% is two stage biological treatment plant.About 3000 of the total treatment plant of Britain almost is two stage biological treatment plant entirely, and there are 630 of municipal sewage in Japan, 2000 of waste water treatment plants, villages and small towns, and wherein second-stage treatment factory and advanced processes factory account for about 98%.Sweden is underpopulated necessarily, but 1540 municipal sewage are arranged, and wherein 91% is two stage biological treatment plant.In the two stage biological treatment scheme that developed country generally adopts, the widest with the application of activated sludge process especially.
A fundamental of activated sludge process is exactly a dissolved oxygen, does not have sufficient dissolved oxygen, and aerobic microbiological just can not be brought into play oxygenolysis, and dissolved oxygen has restricted the treatment effect of activated sludge process.And a typical sewage work, aeration expends and often accounts for 60～80% of working cost.Traditional aerator efficient is low excessively, and the not good energy consumption of aeration that all makes of the control of aeration tank operation is difficult to descend.And Economic development in Along with season, the coverage; The composition of sewage treatment plant inflow all has very big variation; But existing sewage work is not mostly to water quality change adjustment aeration rate; Cause the treatment effect of water outlet bad thereby the aeration deficiency can occur, aeration excessively causes energy wastage, the waste of running cost.Therefore, the quality of aeration rate control has determined the treatment effect and the operation energy consumption of activated sludge process.
The factor that analysis causes oxygen requirement to change finds the factor that influences the aeration oxygen transfer, solves the variation that influent quality changes the oxygen requirement that causes, and is controlled at dissolved oxygen in the optimum range that satisfies biological needs, reaches the demand of biological activity with minimum energy consumption.Develop efficient aerator, grasp the influence of different waste water and operational condition, suit measures to local conditions oxygen transfer; Can be according to the different aeration rates of adjustment automatically of influent quality; Making both to have guaranteed the dissolved oxygen demand, cut down the consumption of energy as much as possible again, is one of research task of environmental work.
The basic physical chemistry model of activated sludge process aeration is exactly the three-phase flow model, and it has three fundamentals, and the one, the mikrobe that causes absorption and oxygenolysis, just activated sludge particles (solid phase); The 2nd, organism in the waste water and dissolved oxygen (liquid phase); The 3rd, the main source of dissolved oxygen, the microbubble in the water (gas phase).Do not have sufficient dissolved oxygen, aerobic microbiological just can not be brought into play the aerobic oxygenolysis.Therefore an effective treatment craft just must make mikrobe, and organism fully contacts with oxygen, and three-phase is interacted, and reaches and handles various organic purposes.Thereby in oxygenation, must make activated sludge particles be in suspended state.Oxygenation realizes through aerator with mixing.
Aerator has obtained popularization as a kind of effective sewage disposal device, and its major function is in sewage, to charge into air, makes solid, liquid, gas three-phase thorough mixing simultaneously; In water cycle process, airborne oxygen is dissolved in the water, and fully contact, mix with organism, mikrobe; Supply microbial respiratory, make organism obtain oxidation, thereby improved contaminated ecotope; Make purification of water quality, create the environment that is fit to biological growth.Simultaneously; The electric energy of sewage work mainly consumes on secondary biochemical treatment active sludge aeration system, and in various biochemical treatment processes, aeration process is as a kind of indispensable link; Its quality not only influences sewage biochemical treatment effect, and directly influences the working cost of Sewage Plant.And secondary pollution and occupation of land thereof that the aeration tank causes also can not be ignored.Therefore, how to improve the oxygen transfer efficient in the aeration, reduce the floor space of aeration tank, reduce secondary pollution and just caused relevant professional person's attention.
Summary of the invention
The utility model provides the aeration plate of a kind of river course water pollution control, and this aeration plate is simple in structure, can make the ambient water body form eddy current, and is high to the water body oxygen-transfer efficiency.
The aeration plate of a kind of river course water pollution control, comprise support, be fixed on the said support at least three be in conplane annular hose and a pneumatic tube that is communicated with all annular hoses, the tube wall of described annular hose is provided with solarization air cap.
Described solarization air cap is linear cellular distribution on the tube wall of annular hose.
All annular hoses are circular, and are provided with one heart.
Described support is the rice font support of forming through the cradling piece at annular hose center by four.
Described solarization air cap reduces from the outside aperture of an end near the annular hose inner chamber gradually, can further avoid mud to pour in down a chimney the blocking aeration hole.
The aperture of described solarization air cap is less than 1mm, and the bubble that micro-pore aeration produces is little, and specific surface area is big, makes the air demand variable adjustable, and the oxygen dissolved efficiency is high simultaneously, can satisfy the movable oxygen consumption demand of a large amount of highdensity dominant microfloras, and aeration efficient is increased to original 5 times.
The thickness of pipe of described annular hose is 2～3mm.
The utility model also provides a kind of aerating apparatus, comprises above-mentioned aeration plate and turbofan, and the air outlet of said turbofan is communicated with the inlet end of said pneumatic tube.
During to the water body oxygenation, gaseous diffusion forms eddy current at its periphery to the utility model aeration plate at aeration, and the generation convection current between the levels water body simultaneously makes water reoxygenation accelerate, and has reduced energy consumption.
The utility model flexible pipe is bulging when aeration, and solarization air cap opens, and then owing to closed by hydrostaticpressure effect solarization air cap, under the situation of not using air filter unit, can avoid mud it to be stopped up designs simplification when quitting work.
