Description
Technical field
The utility model relates to a kind of sewage disposal systems, more specifically, it relates to which a kind of be aerated for light filter material
The uniform aeration distribution apparatus of biofilter.
Background technique
Aeration biofilter with lightweight filter material is the end of the eighties at a kind of New biological membrane method sewage that America and Europe grows up
Science and engineering skill, large development is obtained the beginning of the nineties, and maximum-norm handles sewage hundreds of thousands ton up to daily.
Aeration biofilter with lightweight filter material in the process of development, has sufficiently used for reference sewage treatment contact oxidation method and water supply
The mentality of designing in filter tank, that is, the features such as needing aeration, high filtration speed, retain suspended matter, need to periodically backwash, technological principle
To load the lesser particulate filter of a certain amount of partial size in filter tank, filter material surface grows the biomembrane of high activity, inside filter tank
Aeration；When sewage flows through, using filtrate high-specific surface area bring high-concentration biological film oxidative degradation ability to sewage into
Row fast purification, this is biological Oxidative Degradation Process；Meanwhile sewage, when flowing through, filtrate is in compaction state, using particle diameter of filter medium compared with
The biological flocculation of small feature and biomembrane retains the suspended matter in sewage, and guarantees that the biomembrane to fall off will not be with water
It drifts out, this is crown_interception；Operation after a certain period of time, because of the increase of head loss, need to backwash filter tank, be cut with release
The suspended matter and update biomembrane stayed, this is backwash process.
Fig. 1 is the schematic illustration of existing aeration biofilter with lightweight filter material；
As shown in Figure 1, existing aeration biofilter with lightweight filter material includes pond body 1, biological filter is placed with inside pond body 1
The bed of material 11 is provided with water distributing trough 12 on the outside of pond body 1, and water distributing trough 12 is connected to 1 bottom of pond body, for being passed through waste water into pond body 1,
Discharge outlet 13 is provided on the upside of pond body 1, for treated sewage to be discharged, meanwhile, it is provided with and pond body 1 in the bottom of pond body 1
The water inlet pipe 14 and air inlet pipe 15 of inside connection, meanwhile, the side setting backwash drainpipe 16 in pond body 1, further,
Aeration tube 2 is provided in pond body 1.
In order to adapt to the tolerance variation of aeration quantity, the aerator being arranged in aeration biofilter with lightweight filter material is usually
In pond, intracorporal bottom level is fixed with multiple aeration tubes at equal intervals, wherein equidistantly offers exposure on each aeration tube
Stomata, and the diameter of the solarization air cap on adjacent two aeration tubes is different, passes through when in use to form more set aerated conduits
The air-blowing into different aeration tubes is realized atm number aeration and small tolerance aeration, when being normally aerated, is exposed using small area
Stomata is aerated, and when being backwashed, air blast is carried out using the aeration tube of large area solarization air cap, to realize different tolerance
The aeration operation of demand.
When being aerated using aeration tube, since the size of solarization air cap determines, when carrying out blast aeration, when what is blasted
When gas is smaller, due to the influence of liquid in aeration biofilter with lightweight filter material, the gas blasted can be by the lesser solarization air cap of pressure
Interior ejection, so that the size of outlet is uneven on different solarization air caps on aeration tube.
In conclusion the aerator of existing aeration biofilter with lightweight filter material has the following characteristics that
1. in the process of running, the variation of water quality and quantity, the aeration quantity range needed is bigger；
2. required backwash tolerance is much larger than normal aeration quantity in backwash process；
3. two sets of aerated conduits are arranged in usual aeration biofilter with lightweight filter material, a set of for running aeration, a set of to be used for
Backwash aeration, to adapt to different aeration quantity ranges；Even if but in actual moving process be arranged two sets of aerated conduits, also not
It can guarantee that aeration biofilter with lightweight filter material is aerated uniformly under various operating conditions, to influence entire light filter material aeration and biological filter
The treatment effeciency in pond now provides a kind of uniform aeration distribution apparatus for aeration biofilter with lightweight filter material.

With to up-draught.
In conjunction with shown in Fig. 6 and Fig. 7, preferably, it is detachably connected between top board 62 and lower platen 61, thus, to rubber
While rubber mat 5 is fixed, it can be convenient and rubber pad 5 is replaced.
Lower platen 61, outward integrally formed with fixed plate 611, is mutually leaned on along the two sides to parallel to the axis in two fixed plates 611
Close side offers slideway 612, and top board 62 is integrally formed close to the two sides of lower platen 61 and its parallel axis direction
There is the sliding plate 624 that can be slipped in slideway 612, during installation, sliding plate 624 slide-in slideway 612 is fixed.
Further, lower platen 61 and top board 62 are fixed for convenience, wherein slideway 612 is set as section
It is L-shaped, including with the sliding slot 6121 that is connected in the middle part of lower platen 61 and vertical sliding slot 6121 and towards top board 62 1
The limiting slot 6122 of side；Wherein, slip plate 624 slip in sliding slot 6121, slip plate 624 outer edge integrally formed with
The limit plate 625 in limiting slot 6122 can be slipped, further, the section of limiting slot 6122 along its length is wedge shaped, limit
Position plate 625 is similarly wedge shape, when being installed, is arranged by wedge shape, top board 62 and lower platen 61 can be fixed.
Further, rubber pad 5(is as shown in Figure 4) it can be rectangle, during installation, the two sides of rubber pad 5 are connected to
In limiting slot 6122, it is fixed by using sliding plate 624.
The utility model automatically adjusts to the air blast area at aeration opening 21, by the rubber pad 5 of setting to work as
When air-blowing amount size changes, the outlet area of aeration opening 21 also changes, thus when normal aeration or anti-cleaning, so that pond body
Interior aeration quantity is all more uniformly.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
