Abstract
The utility model discloses a kind of multi-functional BAF, filter tank cell body is disposed with into water relief area from bottom to up, filler supporting layer, packing layer, exhalant region, water inlet setting buffers has water inlet, exhalant region is provided with bath outlet and outlet, packing layer is disposed with anthracite coal measure, haydite layer, volcano rock layers and cobblestone layer from bottom to up, is provided with boring aeration pipe in packing layer.It is upflow type aerating biological filter, by selecting the proportion multiple filling layers less than 1, it is possible to clearance is relatively low, the shortcoming of poor denitrification and dephosphorization effect effectively to overcome the filler of tradition BAF to pollute.
Description
Technical field
This utility model relates to technical field of sewage, especially relates to a kind of multi-functional BAF.
Background technology
BAF (Biololgical Aerated Filter is called for short BAF) is to develop America and Europe the end of the eighties
Come a kind of New biological membrane method sewage treatment process, have removal SS, CODCr, BOD5, nitrification and denitrification, denitrogenation dephosphorizing,
Remove the effect of AOX (harmful substance).Most of BAFs of domestic enterprise's application are all up flow type aeration structures, but
It is that in actual use, the effect of denitrogenation dephosphorizing looks into strong man's meaning, and it is relatively low that filler pollutes clearance.
Utility model content
This utility model is for the deficiencies in the prior art, and it is raw that technical problem to be solved is to provide a kind of multi-functional aeration
Thing filter tank, it is upflow type aerating biological filter, by selecting the proportion multiple filling layers less than 1, it is possible to effectively overcome tradition
The filler pollution clearance of BAF is relatively low, the shortcoming of poor denitrification and dephosphorization effect.
This utility model is to make above-mentioned technical problem be addressed by the following technical programs.
Multi-functional BAF, filter tank cell body is disposed with into water relief area from bottom to up, filler supporting layer, fill out
The bed of material, exhalant region, water inlet setting buffers have water inlet, exhalant region be provided with bath outlet and outlet, packing layer from down to
On be disposed with anthracite coal measure, haydite layer, volcano rock layers and cobblestone layer, packing layer is provided with boring aeration pipe.
As preferably, boring aeration pipe uses elevated boring aeration tubular construction.
As preferably, boring aeration pipe is arranged on the lower end of packing layer.
As preferably, boring aeration pipe is arranged on the height and position of 3rd/2nd to four/3rds of anthracite coal measure.
As preferably, boring aeration pipe is aperture single-hole membrane aerator upward.
As preferably, filler supporting layer is the cobblestone layer of big particle diameter.
The beneficial effects of the utility model:
1. overall structure floor space is little, and treatment effect is more preferable, and aerating system is not easily blocked, and effluent quality is excellent.
2. the elevated boring aeration tubular construction of boring aeration pipe employing, and it is arranged on the lower end of packing layer, be conducive to anti-
Nitrification strengthens denitrification effect, and it is high that filler pollutes clearance, and Nitrogen/Phosphorus Removal is more preferable.
3. filler supporting layer is set to the cobblestone layer of big particle diameter, it is possible to ensure that water-gas distribution uniformly flows upwardly toward many metafiltration
The packing layer of material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-water inlet, 2-filler supporting layer, 3-anthracite coal measure, 4-haydite layer, 5-volcano rock layers, 6-cobblestone layer,
7-washes by water outlet, 8-exhalant region, 9-outlet, 10-boring aeration pipe, and 11-is intake relief area, 12-filter tank cell body.
Detailed description of the invention
Below by embodiment and combine accompanying drawing this utility model is described in detail.
The multi-functional BAF of this utility model as shown in Figure 1, uses single biological aerated filter processing system,
Including upflow type aerating biological filter and inlet and outlet system, gas distribution system and rinse-system.Filter tank cell body 12 is the most successively
Be provided with into water relief area 11, filler supporting layer 2, packing layer, exhalant region 8, water inlet relief area 11 be provided with water inlet 1, water outlet
District 8 is provided with bath outlet 7 and outlet 9.Filler supporting layer 2 uses the cobblestone layer of big particle diameter, it is possible to ensure water-gas distribution
Uniformly flow upwardly toward packing layer.Packing layer uses multilamellar filtrate, and packing layer is disposed with anthracite coal measure 3, haydite from bottom to up
Layer 4, volcano rock layers 5 and cobblestone layer 6, effluent quality is more excellent.In packing layer, it is provided with boring aeration pipe 10, is preferably
Aperture single-hole membrane aerator upward, uses elevated boring aeration tubular construction, and is arranged on the lower end of packing layer, specifically
In the present embodiment, as figure is anthracite coal measure 3 3/2nds to four/3rds height and position, be so more beneficial for anti-nitre
Changing and strengthen denitrification effect, it is high that filler pollutes clearance, and Nitrogen/Phosphorus Removal is more preferable.
This utility model is not limited to above-described preferred implementation, can obtain based on those skilled in the art
The known technology known or use is caned the various deformation of equivalence replacement and the embodiment of change, every base in prior art
Conceive, within should be included in protection domain of the present utility model in spirit of the present utility model or technology.
