Description
Technical field:
The invention belongs to sludge treatment field more particularly to a kind of aerobic reaction pond sewage treatment biofilm bed device and its
Application method.
Background technique:
Sanitary sewage is the waste water being discharged in resident's daily life, is mainly derived from residential architecture and public building, is such as lived
Between residence, organ, school, hospital, shop, public place and industry hygiene etc..Pollutant contained by sanitary sewage is mainly
Organic matter, such as protein, carbohydrate, fat, ammonia nitrogen.The organic matter being present in sanitary sewage is extremely unstable, is easy
It degenerates and generates stench.Bacterium and pathogen in sewage using organic matter in sanitary sewage as nutrition mass propagation, can lead to
Infectious disease from spreading is popular.Therefore, it must be handled before sanitary sewage discharge.The means of sewage treatment have very much, common example
Such as gravitational settling, sedimentation basin, activated sludge process, biofilm, chemical precipitation method, oxidation-reduction method, absorption method etc..Among these
Biofilm is a kind of current widely used method for treating water.Biofilm be make series flow of sewage through filler or certain
Carrier (such as rubble, clinker or plastic honeycomb).Membranaceous biological sludge is just capable of forming on filler, the membranaceous biological sludge quilt
Referred to as biomembrane, biomembrane attachment are known as biofilm bed.A large amount of microorganism is bred on biomembrane, can be played and activity
The same catharsis of sludge, is adsorbed and the organic pollutant in sewage of degrading.
Biological film process, the system for the bioremediation that microorganism grows along solid (can claim biofilm bed) surface in waste water
Claim.It is therefore named because micropopulation grows into mucous membrane shape along the surface of solids.When waste water and biofilm contact, pollutant is from water transfer
It moves on on film, to be handled.When biofilm bed, which is grown the membranoid substance formed by microorganism, to be covered, biomembrane is alternately
It is come into full contact with useless water and air, constantly obtains pollutant and oxygen, purify waste water.It is generated between film and disk because of rotation
Shearing stress increases with the increase of the thickness of film, and to a certain extent, film falls off from disk, flows away with water.Realize the place of sewage
Reason.
But bio-disc system need to carry out in reaction tank face, due to being unable to ingress of air inside pond, cannot use, lead
It causes its space utilization rate not high, large area is needed to take up an area.
Another method is that biofilm bed is fixed in tooth, then by air pump to bottom pump gas, but is easily disturbed in this way
Dynamic bottom of pond mud, and fixed type biological film bed, are not easily cleaned, and biomembrane is not easily to fall off, cause biomembrane blocked up, and corrupt thing occurs
Therefore.
Summary of the invention:
The purpose of the present invention is to provide a kind of aerobic reaction pond sewage treatment biofilm bed device and its application methods, originally
Invention increases the response area of biomembrane by the structure of quasi- sea anemone, is easy to capture the suspended matter in sewage and accelerates water body purification
Effect.While (gas) throughput rate that can be infused by control, it so that flexible hollow is stretched and is crimped, so that obtaining blocked up biomembrane timing
It peels off, avoids corrupt accident, and facilitate the expansion of control biofilm bed and collapse, control response area, accelerate reaction efficiency, also
Reaction tank is facilitated to clear up.

Further to improve, the lug boss is in gas vent periphery.
Further to improve, the gas vent is one-way vent.
Further to improve, the coiled structure includes the elastic ribbon of initial as curly form.
Further to improve, the elastic ribbon is rubber strip or resilient plastic straps or metal band.
It is further to improve, the second hollow hoses are fixed with along elastic ribbon length direction, second hollow hoses one end connects
It is connected with the second ventilating mechanism, other end closure.
Further to improve, first ventilating mechanism and the second ventilating mechanism are air pump.
Further to improve, first hollow hoses, the first ventilating mechanism and the second ventilating mechanism are installed in pedestal
On, pedestal is connected with lifting device；First ventilating mechanism and the second ventilating mechanism is wired or wireless is connected with control system, control
System includes PLC controller or intelligent computer or smart phone.
Further to improve, the lifting device is cylinder or oil cylinder.
A kind of application method of aerobic reaction pond sewage treatment biofilm bed device, includes the following steps: Step 1: passing through
First ventilating mechanism is ventilated to the first hollow hoses, by air pressure inside the first hollow hoses, overcomes the volume of coiled structure
Transverse stress stretches, while gas is discharged from gas vent, and along the first hollow hoses gradually uplink, hollow soft to be attached to first
The microorganism of tube outer surface supplies oxygen；Step 2: when needing to remove the microbial film of the first hollow hoses surface attachment, control the
One ventilating mechanism circulation reduces and increases ventilatory capacity, so that the first hollow hoses circulation crimps and stretch to form shake, by surface
Microbial film shake off；
Step 3: the first ventilating mechanism stops gas supply when needing to clear up bottom of pond, pedestal is jacked and is discharged by lifting device
Face, thus easy cleaning bottom of pond.
Detailed description of the invention:
Fig. 1 is the overall structure diagram of embodiment 1；
