As the further improved procedure of such scheme, the first control valve is pressure regulator valve.
The invention has the beneficial effects as follows:
By injecting the form of specific carbon source in the domestication tank to sealing, suppress the growth of miscellaneous bacteria, the target microorganism in domestication tank is made to become dominant bacteria, thus reach the object of domestication, and by arranging aeration tank, make target microorganism accelerates multiplication arrive certain quantity, and finally out screened, the present invention is simple to operate and production efficiency is high, is easy to carry out production control.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the one-piece construction schematic diagram of one embodiment of the invention;
Fig. 2 is the aeration tank sectional view of one embodiment of the invention.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present invention, concrete structure and generation, to understand object of the present invention, scheme and effect fully.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
It should be noted that, if no special instructions, when a certain feature is called as " fixing ", " connection " in another feature, it can directly be fixed, be connected in another feature, also indirectly can fix, be connected in another feature.In addition, it is only relative to the mutual alignment relation of each integral part of the present invention in accompanying drawing that the upper and lower, left and right used in the present invention etc. describe.
In addition, unless otherwise defined, all technology used herein are identical with the implication that those skilled in the art understand usually with scientific terminology.The term used in specification sheets is herein to describe specific embodiment, instead of in order to limit the present invention.Term as used herein " and/or " comprise the arbitrary combination of one or more relevant Listed Items.
With reference to Fig. 1, show the one-piece construction schematic diagram of one embodiment of the invention, comprise domestication tank 10, domestication tank 10 adopts corrosion resistant material to make, and can not affect its stopping property through using for a long time.Also comprise the carbon source tank 20 and the nitrogenous source tank 30 that provide microorganism growth desired substance, it passes through pipe connecting 40 UNICOM with domestication tank respectively, and preferably, carbon source is target organic exhaust gas to be degraded.Pipe connecting 40 is also provided with the pressure regulator valve 41 that can control gaseous tension, and it can by the injection rate regulating the mode of pressure to control gas.
Comprise aeration tank 50, it is tightly connected by the lower exit port of the second control valve 51 with domestication tank 10.
Above domestication tank 10, be also provided with filler funnel 60, it is tightly connected by the 3rd control valve 61 with domestication tank 10.
The mud fetched by sewage work is made mixed solution, then injects domestication tank 10 by filler funnel 20, and cut off domestication tank 10 and extraneous UNICOM by the second control valve 51 and the 3rd control valve 61, thus form airtight environment in domestication tank 10.Multiple different microorganism may be there is in mixed solution, in order to obtain satisfactory degradation bacteria, need to carry out acclimation, in the present embodiment, the mode of domestication is inject target organic exhaust gas to be degraded as unique carbon source by carbon source tank 20 to timing in domestication tank 10, simultaneously and inject nitrogenous source by nitrogenous source tank 30, the gaseous constituent of taming in tank 10 is made to be converted into target organic exhaust gas by normal atmospheric, in this case, some microbial death, some is then under domestication pressure, its gene type changes, the bacterial classification finally screened is then the target degradation bacteria can survived by decomposing this object gas, thus reach the object of screening.
Nitrogenous source can be ammonia, nitrogen or air in the present embodiment.
In the present embodiment, the injection of target organic gas is progressively, preferably, be in domestication tank 10 stage by stage pass into low, in and the target organic exhaust gas of high density.
In the present embodiment, the second control valve 51 and the 3rd control valve 61 are preferably stopping valve.
After domestication after a while, the target degradation bacteria in mixed solution becomes dominant bacteria, opens the second control valve 51, and mixed solution is transferred to aeration tank 50 breed by being tamed tank 10.With reference to Fig. 2, aeration tank 50 is in communication with the outside by aeration tube 52, air can enter in aeration tank 50 by aeration tube 52, preferably, also be provided with around its inwall diffuser tube of a week 53 at aeration tank 50, it is communicated with aeration tube 52, extraneous air can be diffused in aeration tank 50 by diffuser tube 53 uniformly, preferred further, diffuser tube 53 is evenly equipped with some perpendicular and vertically diffusion be down in charge of 54, its outlet is positioned at the bottom of aeration tank 50, air can be made like this to rise to the process of liquid level bottom mixed solution, better contact with mixed solution, accelerate the breeding of degradation bacteria.
The bottom sidewall of aeration tank 50 is provided with some relief holes 55, and carrying out in reproductive process, described relief hole 55 is sealed by sealing cover 56, after breeding completes, sealing cover 56 is replaced to drainage conduit 57, is discharged by mixed solution and carries out subsequent operations.
Also be provided with in aeration tank 50 and stir flabellum 58, stir flabellum 58 to stir mixed solution, degradation bacteria is fully contacted with oxygen, preferably, the distalmost end of flabellum 58 and the inwall of aeration tank 50 are fitted, it is vertically highly greater than the diameter of relief hole 55, and like this when relief hole 55 connects drainage conduit 57, the rotation of flabellum can force mixed solution to be discharged.
In the present embodiment, the present invention is mainly used in screening degradation bacteria, but and do not mean that the screening being only limitted to degradation bacteria, the present invention can be used for similar microorganism equally, only need replace the nutritive substance injected in domestication tank.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
