Description
Technical field
The present invention relates to a kind of culture device and method of sewage disposal microorganism species, specifically a kind of culture is simultaneously
Store the device and method of sewage disposal activity flora.
Background technology
In the processing procedure of organic sewage, biological activated sludge method obtains because its effective removal to pollutant is high
Widely use, biological activated sludge method is that the dominant microflora applicable according to the classification selection of pollution sources is handled organic sewage
Method, its absorption and oxidability to organic matter is strong, and treatment effeciency is high.
Bioactivity strain is present in the sludge and sewage of sedimentation basin with spore shape, and advantage is converted into by spore shape
Activated sludge flora needs the cultivation cycle of several days or more than ten days, because the active flora turned out is all there is also certain life-span
Phase, it is therefore necessary to before in this generation, activity flora life cycle terminates, the active flora of storage a new generation.Although in clarifier sludge
Microbe species and quantity are a lot, but significant portion of thalline is in inactivation or low activity state, these microorganisms are back to life
Change and generally require certain cultivation cycle and make its activation after pond, organic matter that can be in efficient degradation sewage.Therefore want
Improve microorganism to the treatment effect of organic sewage just it has to be ensured that in sludge high activity flora quantity and accounting.
At present often there is the problem of fluctuation of service in bioanalysis activated sludge water treatment system, i.e., when the pollution in sewage
When source speciality changes, applicable dominant activity flora can not participate in degraded biochemical reaction by timely call, or even not have for the moment
There is applicable dominant activity flora source, this will necessarily cause sewage disposal system, and disposal ability declines in a certain amount of time, so as to
So that the water quality of discharge can not continue to keep up to standard.Existing solution method is that carbon source is directly added in biochemistry pool is micro- to accelerate
The active rate of biological flora, but this method has also aggravated the organic loading of sewage disposal system simultaneously, directly affects technique
Disposition, cause effluent quality big ups and downs, cause water outlet consequence not up to standard.
The content of the invention
An object of the present invention is just to provide a kind of equipment cultivated and store sewage disposal activity flora, existing to solve
When pollution sources speciality changes in some activated sludge water treatment systems, it is impossible to the problem of obtaining dominant activity flora in time.
The second object of the present invention is just to provide a kind of method cultivated and store sewage disposal activity flora, excellent to realize
The high activity storage of gesture flora, in case activated sludge water treatment system can call in dominant activity flora in time when needing.
What the present invention was realized in：
It is a kind of to cultivate and the equipment that stores sewage disposal activity flora, it is characterized in that, including it is culture tank, described for monitoring
The technology controlling and process of technological parameter and parameter acquisition devices, the selective illumination apparatus being arranged on above the culture tank in culture tank
With the aerator for being arranged on the culture pot bottom；
The tank body outer sheath of the culture tank is provided with electrothermal water bath attemperator, and bacterium source is provided with the top of the culture tank

Device is connected, and sewage draining exit is provided with the bottom margin side of the culture tank, and the sewage draining exit is connected with blowoff line, the blowdown
Pipeline is provided with blowoff valve, is provided with discharging opening in the bottom margin opposite side of the culture tank, the discharging opening passes through discharge nozzle
Road is connected with the biochemistry pool of sewage disposal system, and discharging pump is provided with the discharging pipeline, close in the discharging pipeline
One end of the biochemistry pool, which is provided with, calls control valve, goes out a return line, the return duct in the discharging pipeline top set
Road is connected with the top of the culture tank.
The aerator includes micro-hole aerator and source of the gas, and the micro-hole aerator is arranged on the inside of the culture tank
On bottom surface, the source of the gas is arranged on outside the culture tank and is connected with the micro-hole aerator.
Present device can realize depositing for the culture of dominant activity flora, the continuity of strain group activity and dominant activity flora
Storage, when the biochemistry pool of sewage disposal system occurs abnormal, effective flora can be supplemented for it in time, fast quick-recovery biochemistry pool is micro-
The quantity and activity of biological flora, compared with directly adding the method for carbon source to biochemistry pool, shorten microorganism species growth institute
The time of consumption, at the same avoid the sewage disposal system Organic loading shock as caused by adding carbon source and effluent quality fluctuation
Problem.Moreover, the present invention, independently of sewage disposal system, device work and the free degree of modes of emplacement are high, can suit measures to local conditions, spirit
It is living to utilize existing place, without increasing extra reconstruction expense.
What the second object of the present invention was realized in：A kind of method cultivated and store sewage disposal activity flora, its
Comprise the following steps：
Culture described in claim 1 and the equipment for storing sewage disposal activity flora are set a,；
B, activated sludge bacterium source is put into culture tank by bacterium source input port, while interface is fed to training by nutrient solution
Support in tank and inject nutrient solution, and open drive device, bacterium source is mixed with nutrient solution in the presence of stirring rod；
C, selective illumination apparatus is opened, selectes the spectroscopic light source of matching to culture tank light projector；Open aerator, control
It is 1: 1 ~ 3 to be aerated WGR；Electrothermal water bath attemperator is opened, it is 20 ~ 30 DEG C to control temperature in culture tank；
D, technology controlling and process and parameter acquisition devices are opened, monitor the activation degree of flora in culture tank in real time, and according to bacterium
The activation degree monitoring collection value of group in a liquid, the unlatching of control of sewage disposal valve, the active bacteria logarithmic proliferation phase will be spent
Activated sludge is discharged by blowoff line；After discharge crosses the activated sludge of logarithmic proliferation phase, fed again by nutrient solution
