Description
Technical field
The present invention relates to microbiological anaerobic processing and biogas, and field, specially internal-circulation type bioreactor occurs, can
For the Anaerobic Treatment of organic waste, production and collection biogas.
Background technique
Anaerobic digestion reaction refers to organic matter under anaerobic, is degraded by anaerobe and generates the process of biogas.
Biogas is the mixed gas containing multiple gases component, and wherein 50%~70%, carbon dioxide content accounts for the content of methane
25%~40%, other volume of gas account for about 2%.Biogas can burn, and it is direct that the methane after purification can be used as natural gas
It utilizes.Since anaerobic digestion reaction can efficiently handle Various Complex organic matter, and energy gas is generated, therefore answer extensively
Processing for industrial or agricultural organic exhaust gas object.
Anaerobic reactor is the key device of anaerobic digestion reaction, and the height of anaerobic digestion efficiency produces gas velocity degree and energy
Consumption and cost are all an important factor for influencing anaerobic reactor type selecting.Anaerobic reactor is constantly studied and is innovated,
It is the key that improve anaerobic digestion reaction efficiency.The development of anaerobic digestion reaction vessel also goes through the different stages, the first generation
Anaerobic reactor, including conventional anaerobic reactor (CADT), full-mixing type reactor (CSTR) and anaerobic contact digestor
(ACP), the features such as reactor feature in this stage is that common configuration is fairly simple, and investment is small, and operational management is fairly simple,
Suitable for high concentration or the organic wastewater of high suspended matter, but there is also hydraulic detention times simultaneously long, the water quality of water outlet
The drawbacks such as poor.Second generation anaerobic reactor, including anaerobic filter (AF), upflow anaerobic sludge blanket reactor (UASB) are detested
Oxygen baffled reactor (ABR), this kind of reactor have treatment effeciency high, and load resistance ability is strong, and effluent quality preferably waits spies
Point, the organic wastewater relatively low suitable for SS content, but it is larger there is also investing, equipment operation and maintenance cost are higher
The disadvantages of.Third generation anaerobic reactor, including Expanded Granular Sludge Bed Reactor (EGSB), internal-circulation anaerobic reactor (IC),
Upflow sludge bed reactor (UBF) etc., this kind of reactor have treatment effeciency is high, and load resistance ability is strong, and effluent quality is good etc.
Feature, but the investment of equipment is relatively large, it is stringent to waste water SS content requirement.Therefore, it is necessary to comprehensively consider organic wastewater
Feature, scale of investment, processing cost, the various aspects factor such as income reasonably select suitable anaerobic reactor.To anaerobic reaction
The transformation and innovation of device, it should the advantages of retaining former reactor, the shortcomings that reducing reactor and drawback, while also to consider to set
Standby cost and cost.
Since its structure is simple, raw material comes into full contact with full-mixing type reactor (CSTR) with substrate, and fermentation rate is high, volume
The features such as factor of created gase is high, and operational management is simple, low energy consumption, is still widely used for the various high concentrations of industrial or agricultural, higher suspension so far
The processing of object, organic wastewater with difficult degradation thereby.But meanwhile the major defect of the technique is can not to separate hydraulic detention time and solid
Residence time, sludge retention time are equal to hydraulic detention time, sufficient concentrations of sludge cannot be accumulated in reactor, in addition, table
The dross of layer is easy crust, causes gas overflowing unsmooth.Since sufficient concentrations of sludge cannot be accumulated, to the SS of material
There has also been certain limitations for concentration, reduce the application range of technique.

~60 ° are arranged in upward on the central axis.
Object of the internal-circulation type bioreactor of the present invention under impeller and intermediate guiding device effect, in partition
Material is in a downward fluidised form, under the drive of the blade on impeller and guiding device by the channel of partition bottom enter every
Outside plate, and is mixed with the material outside partition and be in upward fluidised form, thus realize material outside partition upward,
The effect of inner-outer circulation directed downwardly mixing, improves mass-transfer efficiency and organic loading, improves the residence time of sludge in partition
And effluent quality, improve the scope of application (such as low SS) of processing sewage, while the three phase separation on reactor body top
The lower gas-liquid separation for realizing biogas and feed liquid of device effect, increases mass transfer, improves gas producing efficiency.
In actual use, fermentation materials are injected from reactor body bottom feed pipe, are evenly distributed on by water distributor
Bottom is mixed under the drive of impeller and internal flow with sludge, is fermented and is generated biogas, biogas drives feed liquid to rise
And assemble at three phase separator, biogas reaches the gas collection area at top through three phase separator, and part feed liquid penetrates three phase separation
Device reaches partition top, then completes circulation under guiding device drive, and most of sludge is retained down, part feed liquid with
Sludge is circulated in three phase separator lower part.
The beneficial effects of the present invention are:
(1) the interior circulation inside and outside local circulation and partition of the material outside partition increases mixing and the mass transfer of material, mentions
Coming into full contact with for high sludge and material, the problems such as the upper layer of reactor body liquid level is less prone to crust, spumes, mentions
The high gas-liquid separation efficiency of biogas.
(2) three phase separator is increased on reactor body top, realizes the three phase separation of solid-liquid-gas, increases sludge
Retention, improve sludge retention time, improve treatment effeciency, waste water lower for solid content equally has very well
Treatment effect, and be not required to supplement sludge, extend application range, such as low SS waste water, reduce mend mud cost.
(3) bottom water distributor charging while, the sludge of deposition can be broken up, for improve sludge activity, subtract
The area Shao Sini increases the treatment effeciency of reactor body, reduces hydraulic detention time, is of great significance.
