Description
Technical field
The present invention relates to a kind of sewage disposal air-lift device.
Background technology
Sanitary sewage includes various bath wateies, sewage and ight soil etc. in urban life, mostly be nontoxic inorganic salts, comparison of ingredients is fixed, main containing organism such as carbohydrate, protein, amino acid, fat, relatively be applicable to bacterium, virus growth and there is certain fertilizer efficiency, can be used to irrigated farmland.Simultaneously, in sanitary sewage, the plant nutrient substance such as nitrogen, phosphorus content is more, easily cause the eutrophication of water body, one of primary pollution source of water body, therefore need to process sanitary sewage and after making it up to standard, could be disposed in rivers and lakes and be gone, thus be overcome the water pollution because sanitary sewage causes.As the important component part of sewage disposal device, traditional air-lift device complex structure, floor space is large, and decontamination effect improving is poor.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of sewage disposal air-lift device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sewage disposal air-lift device, comprise air-lift device framework, air-lift device framework is provided with air lift dividing plate, and gas device is separated into air lift district and clear water zone by air lift dividing plate, communicates bottom air lift district and clear water zone; Described air lift zone center is provided with airlift, 0.3 ~ 0.5m at the bottom of airlift distance pond, and be provided with packing layer outside airlift, airlift is built-in with blast main extraneous air being inputted air lift district, offers diffusion hole bottom blast main; Be provided with the slope being convenient to mud landing bottom described clear water zone, the angle of inclination between slope and horizontal plane is 40 ~ 60 °, and clear water zone sidewall offers rising pipe.
Further, described airlift comprises lifting pipe, and lifting pipe top is connected with splash box, splash box is vertically installed with the flow deflector arranged in radiation, offers multiple water distributing pore between adjacent two pieces of flow deflectors.
Further, the angle of inclination between described slope and horizontal plane is 45 °.
Further, described packing layer is honeycomb filler.
Further, described air-lift device framework is stainless steel frame.
Further, described blast main is pvc pipe.
By adopting preceding solution, the invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, stable, maintenance management convenience, sewage disposal emission request on a small scale can be adapted to preferably, there is good organics removal, the effect of ammonia nitrogen, also have that initial cost is low, working cost is few simultaneously, the energy-saving and cost-reducing advantage such as obvious.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Wherein, 1, air-lift device framework, 2, air lift district, 3, splash box, 4, flow deflector, 5, blast main, 6, water distributing pore, 7, packing layer, 8, air lift dividing plate, 9, rising pipe, 10, clear water zone, 11, slope, 12, diffusion hole, 13, lifting pipe.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
Disclose a kind of sewage disposal air-lift device with reference to figure 1 the present embodiment, comprise air-lift device framework 1, air-lift device framework 1 is provided with air lift dividing plate 8, and gas device is separated into air lift district 2 and clear water zone 10 by air lift dividing plate 8, communicates bottom air lift district 2 and clear water zone 10; Center, air lift district 2 is provided with airlift, 0.3m at the bottom of airlift distance pond, and be provided with packing layer 7 outside airlift, airlift is built-in with the blast main 5 extraneous air being inputted air lift district 2, offers diffusion hole 12 bottom blast main 5; Be provided with the slope 11 being convenient to mud landing bottom clear water zone 10, the angle of inclination between slope 11 and horizontal plane is 45 °, and clear water zone 10 sidewall offers rising pipe 9.
Airlift comprises lifting pipe 13, and lifting pipe 13 top is connected with splash box 3, splash box 3 is vertically installed with the flow deflector 4 arranged in radiation, offers multiple water distributing pore 6 between adjacent two pieces of flow deflectors 4; Packing layer 7 is honeycomb filler; Air-lift device framework 1 is stainless steel frame; Blast main 5 is pvc pipe.
Air from gas blower gos deep into bottom airlift through blast main 5, spread through diffusion hole 12, in lifting pipe 13, form the aqueous vapor milk sap of empty G&W, because the proportion of aqueous vapor milk sap is less than water, under the effect of hydrostaticpressure, aqueous vapor milk sap rises along lifting pipe 13.Be provided with splash box 3 on lifting pipe 13 top, through splash box 3 water distribution, aqueous vapor milk sap forms the splash source centered by airlift, declines along packing layer 7.In the process declined along packing layer 7, waste water contacts organics removal and ammonia nitrogen with the microorganism that packing layer 7 grows.Last aqueous vapor milk sap flow to air-lift device framework 1 bottom, is formed and once circulates.
Waste water flow to clear water zone 10 after repeatedly circulating, and carry out solid-liquid separation, mud is bottom slope 11 landing to treatment tank body, and waste water is discharged by rising pipe 9.
This sewage disposal air-lift device structure is simple, reasonable in design, stable, maintenance management convenience, sewage disposal emission request on a small scale can be adapted to preferably, there is good organics removal, the effect of ammonia nitrogen, also have that initial cost is low, working cost is few simultaneously, the energy-saving and cost-reducing advantage such as obvious.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine its technical scope according to right.
