Abstract
The utility model discloses a water and gas distribution system for the aeration biological filter, comprising a water and gas distributor, an aerator, an aeration membrane, a distribution ducting, and a reinforcement concrete water distribution board; the water and gas distributor is arranged on the water distribution board and the bottom plate of the distributing channel of the filter chamber; The aerator, the aerator membrane and the distribution ducting are evenly arranged inside the chase of the pipe chase type water and gas distributor of the filter chamber; the sealing flange holes at the side end of the aerator, the aeration membrane, the distribution ducting are tightly connected with a sealing flange hole at the side of the chase. The utility model has the advantages of short construction cycle, low cost and good aeration, oxygen charging and reversal circulation effect.
Description
Technical field
The utility model belongs to a kind of sewage disposal specific equipment.
Background technology
At present, sewage disposal both at home and abroad and reusing sewage separately carry out mostly, promptly build sewage disposal respectively and sewage returns engineering, construction period is long like this, investment is huge, the biological aerated filter process of sewage disposal and reusing sewage has now appearred integrating in the world, but filter tank water and air distributing system and device is made of water and air distributing pipe, aerating system etc., and this structure technology is not overripened, and effect is undesirable.
The utility model content
The purpose of this utility model just provides that a kind of cost is low, aeration aerating and the good BAF water and air distributing system of backwash effect.
For achieving the above object, the technical scheme that the utility model provides is: a kind of BAF water and air distributing system, it comprises water and air distributing device, aerator, aeration film, gas-distribution pipe, steel concrete water distribution board, water and air distributing device is arranged on filter tank distributing flue water distribution board and the pond base plate, aerator, aeration film, gas-distribution pipe are evenly arranged in the cell body of filter tank tube and tank type water and air distributing device, and the tongued and grooved flanges hole of aerator, aeration film, gas-distribution pipe and cell body side is tightly connected.
Compared with prior art, the utlity model has short construction period, cost is low, and aeration aerating and the good advantage of backwash effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the cross sectional representation of the utility model water and air distributing device.
Embodiment
BAF water and air distributing system shown in Fig. 1,2, it is made up of water and air distributing pipe row, aerator 2, aeration film 3, gas-distribution pipe 4, steel concrete water distribution board etc., and water and air distributing device 1 is evenly arranged on filter tank distributing flue water distribution board and the pond base plate.Aerator 2, aeration film 3, gas-distribution pipe 4 are evenly arranged in the cell body of filter tank tube and tank type water and air distributing device, laterally aerator is evenly arranged, and there is the tongued and grooved flanges hole with the cell body side to be tightly connected, cell body and pond base plate be with the pattern sealing of rectangle hard rubber seals circle, and stainless steel platen of fixing, compressing with the pond base plate and stainless steel expansion bolt, nut etc. match.
Fixedly connected with arc wafer type flange between two aerators 2 and the water and air distributing pipe 1.The distribution by-pass line is evenly arranged on the water distribution board medullary ray of filter tank.Being the cobble supporting layer above the tube and tank type water and air distributing device, is the quartz sand filtering layer above the supporting layer, the filtering layer basically identical in this and traditional filter tank.Among the figure, joint bolt 5, sealing-ring 6, bolt 7, gasket 8, clip 9, high poly-seal gum 10, stainless steel built-in fitting 11, distribute water and air pipe 12, screed-coat 13, cast aluminium pressing plate 14, expansion bolt 15.
The cross section top of water and air distributing device 1 shown in Figure 3 is semicircle, and the bottom is a rectangle, and outer flanging is arranged at the bottom.The whole system operation principle is to utilize micro-pore aeration oxygenation and filter tank distribution back flushing in the sewage disposal to combine in relatively limited area of space, tube aerator is arranged in the cell body of tube and tank type water and air distributing device, tube aerator is connected with the flat flange seal that passes through of cell body outboard end, also being provided with arc wafer type flange simultaneously makes two aerators fixedly connected with middle ABS standard gas-distribution pipe, the air that comes out from gas blower enters the tubular type aeration by pipeline like this, after aeration finishes, decomposition postprecipitations such as the organism in the sewage get off, settled sludge is more on the quartz sand filtration layer in the filter tank, after retaining power descends, start the water and air distributing device under the water distribution board simultaneously, allow the gas and the water of certain pressure enter in the water and air distributing canal, because pressurized air is lighter, make the upper strata of canal form an air cushion layer soon, then water enters the tube and tank type water and air distributing device below water distributor, the air inlet port of air above water distributor enters the tube and tank type water and air distributing device, mutually stir the back gas-vapor mix body that nebulizes and enter filtering layer from a few deploying pores in tube and tank type water and air distributing device top, so just formed the air water mix backwash, the process of back is similar to traditional filter tank air-water backwashing, after reaching the regulation effect, back flushing finishes, the cycle samsara that beginning is next new.
