Abstract
The utility model discloses a high-efficiency ammonia-nitrogen removal biological aerated filter. The high-efficiency ammonia-nitrogen removal biological aerated filter comprises a filter tank, a porous plate is arranged in the filter tank, a material filtering layer is filled above the porous plate, an aerator pipe is arranged in the material filtering layer, and an air pipe is additionally arranged below the porous plate; a bearing layer is arranged above the material filtering layer; and a water inlet is formed in the bottom of the filter tank, and a water outlet is formed in the top of the filter tank. According to the high-efficiency ammonia-nitrogen removal biological aerated filter, the structure is simple, the design is scientific, the sewage flow rate is decelerated, so that sewage can fully contact with microorganisms in the material filtering layer, and then is discharged after being decomposed, so that the sewage treatment efficiency and the microorganism utilization ratio are improved greatly.
Description
Technical field
The utility model belongs to field of Environment Protection, is specifically related to a kind of efficient except the ammonia nitrogen BAF.
Background technology
At present, the biological filter has been widely used in sewage disposal.The biological filter be with microorganic adhesion on carrier or filtrate, decompose organism in the sewage by the metabolism of microorganism.Traditional biological filter is that the microorganism that is attached on the carrier is directly dropped into, and when processing like this, microorganism contacts insufficient with sewage, and also even not, the utilization ratio for the treatment of effect and microorganism is all on the low side.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of efficient except the ammonia nitrogen BAF.
Technical scheme: in order to reach the foregoing invention purpose, the utility model specifically is achieved like this: a kind of efficient except the ammonia nitrogen BAF, comprise the filter tank, be provided with porous plate in the filter tank, described porous plate top is filled with filter material layer, be provided with aeration tube in the filter material layer, the porous plate below is provided with blast main in addition; Described filter material layer top is provided with supporting layer; The bottom, filter tank is provided with water-in, and the top is provided with water port.
Wherein, described water inlet is provided with clean water outlet in addition.
Wherein, described filter material layer filtrate is granulated active carbon, volcano fitros, haydite or slag.
Beneficial effect: the utility model is simple in structure, and design science by the design of porous plate, has been alleviated effluent flow rate, make sewage can with filter material layer in microorganism fully contact, decompose after again the discharging, greatly improved sewage treating efficiency and microorganism utilization ratio.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
As shown in drawings, the efficient ammonia nitrogen BAF of removing that the utility model provides comprises filter tank 1, is provided with porous plate 2 in the filter tank 1, and described porous plate 2 tops are filled with filter material layer 3, are provided with aeration tube 4 in the filter material layer 3, and porous plate 2 belows are provided with blast main 5 in addition; Described filter material layer 3 tops are provided with supporting layer 6; 1 bottom, filter tank is provided with water-in 7, and the top is provided with water port 8, and water-in 7 places are provided with clean water outlet 9 in addition.
During the utility model work, sewage is imported by water-in 7, and under the pressure-acting of blast main 5, sewage rises, enter filter material layer 3 by the aperture on the porous plate 2, fully contact with microorganism, organism is decomposed by microorganism, and this microorganism absorbs the required oxygen of metabolism by aeration tube 4,6 of supporting layers play the fixedly effect of filter material layer 3, behind the bed of material 3, sewage continues to rise after filtration, is discharged by water port 8.During the back flushing of this device, clear water is imported from clean water outlet 7, open blast main 5 and make the spot of walking to take away on the clear water in the filter tank 1 by pressure.
Claims (3)
