Description
Technical field
The invention belongs to sewage treatment area, a kind of fluidisation rotating-drum biofilter is specifically referred to.
Background technology
In sewage treatment process, biomembrance process is a kind of traditional sewage biological treatment technique, and biomembrance process is utilized and filled out
The biomembrane of apposition growth is contacted with pending sewage on material, pollutant in microorganism and sewage on biomembrane and
Oxygen carries out mass transfer, the pollutant in sewage of being degraded using the bioprocess of microorganism, is purified sewage.It is applied at present
Ripe biomembrance process has many kinds, such as biological rotating disk, biological contact oxidation process, biofilter, biological fluidized bed and MBBR.Gu
There is small hydraulic shear, slow biomembrane renewal, oxygen and the low problem of pollutant mass-transfer efficiency in fixed pattern biomembrane process；Biology turns
Disk, using the rotation of rotating disk, makes the oxygen in the microorganism and air on rotating disk carry out mass transfer, reaches micro- life in application process
Thing is to the demand of oxygen, simultaneously because microorganism is attached on rotating disk, it is not necessary to sludge reflux, sludge will not also be expanded,
This method is simple to operate, management is convenient, energy consumption is low.But the speed of biological rotating disk is relatively small, and specific surface area is low, biomembrane is more
New speed is low, the easy aging of biomembrane, the biodegradable low shortcoming of efficiency.Biological contact oxidation process, biofilter, biological fluidized bed
And MBBR is different from biological rotating disk, using aerator, the renewal speed of biomembrane on filler is improved, but energy consumption is relatively
Greatly.
Activated sludge process is the conventional method in dirty water living creature processing technique, and organics removal effect is good, and other techniques
With reference to N, the P that can effectively remove in sewage, sweeping dirty treatment plant uses activated sludge process, cost of investment and operating cost compared with
Low advantage, in the operation of small-scale sewage treatment plant, the advantage cannot be realized.While the aerobic part of activated sludge process
The shortcomings of oxygen supply must be aerated, there is sludge aging, sludge bulking, big sludge quantity in the process of running, the specialty of operational management
Property it is strong, should not be selected in small-scale small towns, rural sewage treatment.
In small-scale small towns, rural sewage treatment, there is sewage treatment plant's operational management professional ability shortcoming, sewage
The not enough phenomenon of processing cost, causes part of contaminated water processing unit not run normally, fails to reach due effect.
In view of the above problems, nowadays it is badly in need of that a energy consumption is low, treatment effeciency is high, operational management is convenient, maintenance workload is small
