Description
Technical field
The invention belongs to technical field of industrial sewage treatment, and in particular to a kind of HDM anaerobic membrane biosystems treatment process.
Background technology
Traditional Anaerobic Microbiological Treatment Technology is under anaerobic state, and the organic matter in sewage is by anaerobic bacteria decomposition, generation
It thanks, digest so that the content of organics in sewage is greatly decreased, while generating a kind of efficient sewage treatmentmethod of biogas.
It is used for the precipitating sludge and high-enriched organics of Treating Municipal Sewage treatment plant earliest, and used is all common anaerobic organism
Facture.Common Anaerobic biotreatment method, because the water conservancy residence time is long, processing load is low, and cost and operating cost are relatively high,
So these disadvantages limit application of the Anaerobic biotreatment method in various treatment of Organic Wastewater.The 1950s, mid-term went out
Existing anaerobic reactor, is additionally arranged sludge refluxing apparatus, increases anaerobic sludge concentration in reactor, make anaerobic sludge in reactor
The middle residence time is more than hydraulic detention time for the first time, therefore its treatment effeciency is significantly improved with load.This is Anaerobic Treatment skill
One important development of art.With the development of immobilization technology in biological fermentation engineering, it was recognized that improving dirty in reactor
The importance of mud concentration.First breakthrough development comes across late 1960s, and Young and Mccary have invented anaerobism
Filter tank (device), abbreviation AF.Since the breakthrough of anaerobic technology maximum is the 1970s, Dutch agriculture university's environment system Lettinga
Et al. invention it is upper or anaerobic mud bed, abbreviation UASB has become most widely used anaerobic treatment method at present.AF with
The invention of UASB has pushed a series of new high speed anaerobism based on microbial immobilized and improve sludge mixing efficiency anti-
Answer the research and development of device.Such as it is anaerobic fluidized bed, expanded granular sludge bed and on this basis improve and develop it is numerous
Anaerobic reactor etc..
Since anaerobe is slow-growing, generation time is long, thus ensure sufficiently long residence time be anaerobic technique at
The key condition of work(.Formally with the continuous improvement recognized anaerobic fermentation process, it was recognized that being kept in reactor a large amount of
Microorganism and sludge age as long as possible be the key that improve reaction efficiency and reactor success or failure.
The principle that high-speed system for anaerobic treatment must satisfy is：(1) a large amount of anaerobic activated sludge and foot can be kept
Enough long sludge ages；(2) coming into full contact between waste water and sludge is kept.In order to meet first principle, fixation may be used
Change (biomembrane) or cultivates the mode of the good anaerobic sludge of sedimentation function (granule sludge) to keep anaerobic sludge.Common anaerobism
Reactor (pond) technology is as follows：
The first generation
1) septic tank (septic tank), principle are that solidfied material is decomposed in bottom of pond, the aquation object on upper layer, into pipeline stream
It walks, solidification object (such as excrement rubbish) has sufficient time hydrolysis, anaerobism liquefaction.
Disadvantage：Continuous flow, dross influences effluent quality, and forms slagging layer, has foul smell to distribute, sludge is drawn clearly every year
1 to 2 times.
2) anaerobic contact process, the technique is similar to aerobic activated sludge process, is returned by anaerobic digester, sedimentation basin and sludge
Streaming system forms；Hydraulic detention time in digester is shortened, the residence time of sludge is extended；Energy continuum micromeehanics, keep pond
Internal loading it is uniform；Keep the high concentration of sludge.
The second generation
There are a large amount of anaerobic sludges, top to have phase reactor and sludge heavy in up-flow anaerobic sludge blanket (UASB) reactor
Room drops；High efficiency reactor of the anaerobic sludge without stirring；Most widely used one kind in the anaerobic reactor of a new generation's exploitation.
The third generation
Anaerobic expanded granular sludge bed (EGSB) structure of reactor is similar to UASB；Higher upper flow velocity is used in reactor
Degree；It is granular mud bed in reactor to be in expansionization state.
Current relatively advanced anaerobic reactor UASB and EGSB core keys by waste water, are detested by three phase separator
Oxygen sludge, biogas separation ensure that anaerobic sludge with drainage loss, does not ensure the anaerobic sludge concentration in reactor.
In conclusion traditional Anaerobic Microbiological Treatment Technology has a defect that：The influence factor of activity of anaerobic sludge is more,
Such as temperature, pH environment, organic loading, toxicant cause anaerobic technology stability in application to decline, anaerobism can be caused dirty
Mud volume reduces, weight, is influenced on the actual effect of three phase separator very big.Traditional Anaerobic Microbiological Treatment Technology core
Separator is all built-in, that is, is submerged in inside reactor, due to the limitation of three phase separator, the sludge in anaerobic reactor
High concentration cannot be maintained steadily in the long term.Traditional anaerobic technology need sludge concentration tank and each link to pond body structural requirement too
Height, upgrading difficulty are big.
