Description
Technical field
The utility model relates to a kind of air-lift devices of MBBR filler.
Background technique
With China's expanding economy, environmental problem is increasingly prominent, the sewage disposal plant effluent of each big city early stage construction
Standard is higher than level-one A standard in " urban wastewater treatment firm pollutant emission standard " GB18918-2002, it is most of be second level or
Level-one B standard is faced with and proposes mark transformation situation.The biochemical wastewater treatment technology of international mature is moving-bed biofilm work at present
Skill (MovingBedBiofilmReactor, MBBR), the technique overcome its mass-transfer efficiency is low, treatment effeciency is poor, fluidisation power
The disadvantages of high, with the basic principle of biofilm, the advantages of taking full advantage of activated sludge process, realizes the work of biomembrane process
Property sludge mode is run.MBBR technological principle is under aerobic condition, and when aeration aerating, the rising buoyancy of air bubble pushes filler
Get up with the water body flow of surrounding, is blocked again by filler when air-flow passes through the gap of water flow and filler, and be divided into stingy
Bubble.In such a process, filler is fully stirred and is mixed with water flow, and air stream be fully divided into it is tiny
Bubble increases contact and oxygen transfer efficiency of the biomembrane with oxygen.Under anaerobic, water flow and filler are in submersible agitator
The lower sufficiently fluidisation of effect is got up, and achievees the purpose that biomembrane and processed pollutant come into full contact with and degrade.Therefore, thermopnore
Biomembrane process breaches traditional biological embrane method (blocking and the water distribution unevenness and biological fluidized bed of static bed biomembrane technique
The fluidisation of technique is limited to) limitation, the biological treatment for being applied more broadly in sewage for biofilm established preferable basis.
Although the purpose of Promotion Transformation standard water discharge may be implemented in the technique, but there are still stir uneven, filler accumulation in its application
The problem of.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of air-lift device of MBBR filler, it can effectively solve MBBR work
Skill filler accumulates problem, and engineering cost is low, applied widely, easy to operate.
To achieve the above object, the utility model uses following scheme: a kind of air-lift device of MBBR filler, including current stabilization
Cylinder, collecting pipe, be connected respectively with blower system mention tracheae and stirring pipe, stirring pipe is arranged in intercept net close to water outlet one
The other side of the intercept net is arranged in close to the collecting pipe of biochemical bottom of pond portion for side, lower end, and stabilizing feed well setting is intake in biochemistry pool
Near mouthful, stabilizing feed well is connected with the upper end of collecting pipe, mentions tracheae lower end and is arranged in collecting pipe.
Further, the lower end of collecting pipe is horn mouth, and adjacent to intercept net；Be conducive to the collection of filler.
Further, it mentions and is respectively arranged with valve in tracheae and stirring pipe, the valve is arranged at outside biochemistry pool；It is convenient
Vacuum degree and stirring air pressure in regulation pipe, to adjust the gathering speed of MBBR filler.
Collecting pipe is 90 degree of bend pipes, and horizontal component protrudes into stabilizing feed well from side wall, collecting pipe horizontal component center absolute altitude
It is equal with biochemistry pool water surface absolute altitude；Air lift effect and filler lifting capacity can be improved.
Further, stirring pipe lower end is arranged in biochemical bottom of pond portion position corresponding with collecting pipe；It is promoted as far as possible from bottom
The MBBR filler of accumulation.
The beneficial effect of utility model
The utility model can be used in aerobic tank, it is also possible to applied widely in anaerobic pond；In a biochemistry pool
At least a set of the utility model can be used, the MBBR filler that can thoroughly solve is the problem of pond body end is accumulated；By adjusting
The valve on tracheae and stirring pipe is mentioned, the adjustment that MBBR filler promotes speed can be completed, it is easy to operate；Using the utility model
The installation number of filler impeller equal power device can be reduced, reduces engineering cost, and easy to maintain.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
The utility model include stabilizing feed well 2, collecting pipe 4, be connected respectively with blower system mention tracheae 7 and stirring pipe 8, stir
It mixes pipe 8 to be arranged in intercept net 6 close to 10 side of water outlet, the lower end of collecting pipe 4 is divided close to 3 bottom of biochemistry pool, and with stirring pipe 8
6 two sides of column intercept net, position are corresponding.Stabilizing feed well 2 is arranged near the water inlet 1 of biochemistry pool 3, and stabilizing feed well 2 is upper with collecting pipe 4
End is connected, and mentions 7 lower end of tracheae and is arranged in collecting pipe 4.Collecting pipe 4 is 90 degree of bend pipes, and one end of horizontal component is stretched from side wall
Enter in stabilizing feed well 2,4 horizontal component center absolute altitude of collecting pipe is equal with 3 water surface absolute altitude of biochemistry pool, and the lower end of collecting pipe 4 is loudspeaker
Mouthful, and neighbouring intercept net 6.It mentions and is respectively arranged with valve 9 in tracheae 7 and stirring pipe 8, the valve 9 is arranged in biochemistry pool 3
Outside.
Before use, tracheae 7 will be mentioned and stirring pipe 8 is connected with blower system respectively.In use, opening the valve in stirring pipe 8
Door 9,5 stirring suspension of MBBR filler that gas will be accumulated in intercept net 6 is then turned on the valve 9 mentioned on tracheae 7, into collecting pipe 4
The MBBR filler 5 accumulated at interior gas, mud and intercept net 8 promotes together to be arrived in the stabilizing feed well 2 near water inlet 1, steady
Under the buffering and pressure stabilization function of flow cartridge 2, MBBR filler 5 is fallen from stabilizing feed well 2, is constantly recycled, to make 3 end of biochemistry pool not
There is 5 packing phenomenon of MBBR filler again.
