Description
Technical field
The present invention relates to field of waste water treatment, relate in particular to a kind of separate type anaerobic baffled reactor and method of work thereof.
Background technology
Anaerobic digestion is the biological procedures of a complicacy, and anaerobic fermentation process also extensively exists in nature.Under anaerobic, in the place that water is arranged, organism is easy to take place anaerobic digestion, and the representative product of anaerobic digestion is methane and hydrogen sulfide.Anaerobion, being can be in the mikrobe of decomposing organic matter under the oxygen free condition.Their distributions on earth are very widely.Comprising at the bottom of the lignum of the stomach of humans and animals, plant, seabed, lakebed, the pool and the settling of Jiang Wan, and in various mud, marsh, manure pit and the paddy soil, all there is the anaerobion of different quantities to exist.
The Anaerobic Digestion technology that people developed; Then be in a kind of reactor drum, to create needed nutritional condition of anaerobion and envrionment conditions with the artificial way; Make the anaerobion of accumulation high density in the equipment; To quicken anaerobic fermentation process, make the speed of artificial anaerobically fermenting substantially exceed the spontaneous anaerobically fermenting of occurring in nature.
In the anaerobic treatment process of waste water, the organism in the waste water finally is converted into methane, carbonic acid gas, water, hydrogen sulfide and ammonia under the acting in conjunction of mikrobe.In this process, the metabolic process of different microorganisms influences each other, mutual restriction, forms the complicated ecosystem.Pollutent in the general organic waste water is a macromolecule organic, and these organism exist with solute, suspended substance or colloidal form in waste water.
As shown in Figure 1, the anaerobic degradation process of organic pollutant can be divided into four-stage in the waste water:
1, hydrolysis stage
The polymerization sugar that hydrolysis is defined as complicated non-solubility is converted into the process of simple solvability monose or biglycan.Macromolecule organic is bigger because of relative molecular mass, can not permeate through cell membranes, therefore can not directly be utilized by bacterium, and so hydrolytic process is slower usually, be considered to the rate-limiting step of pbz polymer organism or suspended substance waste liquid anaerobic degradation.Multiple factor possibly influence the speed of hydrolysis and the degree of hydrolysis, generally comprises: hydrolysis temperature; The organic residence time in reactor drum; Organic composition, the for example massfraction of lignin, glucide, protein and fat; The size of organic matter particle; The pH value; The concentration of ammonia: the concentration of hydrolysate (for example voltaile fatty acid).
2, fermentation (or acidifying) stage
Fermentation be defined as organic cpds be electron acceptor(EA) also be the biodegradation process (selfoxidation-reduction reaction) of electron donor, in this process, it is main product that dissolved organic matter is converted into the voltaile fatty acid.Therefore this process is also referred to as acidifying.In this stage, above-mentioned micromolecular compound is converted into simpler compound justacrine to the extracellular in the cell of fermenting bacterial (being the acidifying bacterium).The primary product in this stage has voltaile fatty acid (VFA), alcohols, lactic acid, carbonic acid gas, hydrogen, ammonia, hydrogen sulfide etc.Meanwhile, the acidifying bacterium also utilizes the part material to synthesize new cellular material.
In this stage, lipid acid fermentation can produce hydrogen, so this successful reaction carries out, and must depend on the product methane process of hydrogen consuming, so that make hydrogen concentration maintain lower level.In addition, the degraded of lipid acid can make pH descend, and therefore in reactive system, enough surge capabilities should be arranged.
In the anaerobic degradation process, acidification bacteria must take in the tolerance of acid.Acidization drops at 4 o'clock at pH and still can carry out, and for example people have promptly utilized this characteristic in the slaking of green fodder.But the optimal ph that produces the methane process is at 6.5～7.5, so the decline of pH value will reduce that methane generates and the consumption of hydrogen, and further causes the change of acidizing product composition.Some products for example propionic acid can generate in a large number.Acetogen does not have enough abilities to overcome this change, and the decline of methanogen vigor has further aggravated sour accumulation again, and the pH value is further descended.The anaerobic degradation process therefore worsens, and when serious the formation of methane is ended fully.
3, produce the acetate stage
The product in fermentative acidification stage is converted into acetate, hydrogen and carbonic acid gas in the product acetate stage by acetogen.Usually in anaerobic grain sludge, exist microecosystem, in this system, acetogen is near the bacterial growth that utilizes hydrogen, so hydrogen can be easy to be consumed and make product acetate process to carry out smoothly.
Except many methanogens can utilize the hydrogen, sulphate reducing bacteria and denitrifier also can hydrogen consuming.A spot of in addition acetogen also utilizes hydrogen, and this type acetogen can use hydrogen as electron donor carbonic acid gas and methyl alcohol to be reduced to acetate, and this is that homotype is produced the acetate process.
4, produce methane phase
In this stage, acetate, hydrogen, carbonic acid, formic acid and methyl alcohol etc. are converted into methane, carbonic acid gas and new cellular material.In anaerobic reactor, institute methanogenic about 70% is produced by acetate disproportionation bacterium.In reaction, the carboxyl in the acetate separates from molecular acid, and methyl is converted into methane, and carboxyl is converted into carbonic acid gas, and in neutral solution, carbonic acid gas exists with the form of supercarbonate.
This process is the final step of anaerobic reaction process, and organic acid that the front produced etc. is decomposed into materials such as methane, carbonic acid gas.If this process can not be carried out smoothly, voltaile fatty acid can accumulate significantly, causes the acidifying of total system, and anaerobic reaction is stopped.
Anaerobic digestion process is made up of a series of fermentation reactions, finally can make complicated organism stabilization and be converted into CH
4And CO
2Deng gas.The microflora that these reactions are made up of the different types of bacterium of several big monoids accomplishes jointly.These bacteriums can be divided into four monoids, that is: (1) hydrolysis and fermenting bacterial; (2) hydrogen-producing acetogenic bacteria; (3) homoacetogenic bacteria; (4) methane-producing bacteria; Methane-producing bacteria wherein can be divided into hydrogen nutritional type methane-producing bacteria and acetate nutritional type methane-producing bacteria again.The bacterium of different monoids has different physio-biochemical characteristics, optimum pH scope and nutritional requirement etc.But in general, can this four monoids bacterium be divided into two big types simply, promptly therefore acid formers and methane-producing bacteria also can divide penta two stages with anaerobic digestion process, promptly produce acid phase and produce methane phase.In this two stages. be responsible for bacterium that organism transforms and levy and form and aspects such as physio-biochemical characteristics all exist very big difference.Acting in the fs mainly is hydrolysis and/or fermenting bacterial; They can be hydrolyzed to the carbon containing larger molecular organics of complicacy simple small molecules monose, amino acid, lipid acid and glycerine etc. and then further fermentation a lot of for the kind of various organic acid s this bacterium in stage, and their principal feature is: metabolic capacity is strong, reproduction speed is fast (doubling time lack most only be about dozens of minutes), very strong etc. to the flexibility of envrionment conditions.Bacterium then mainly is a methane-producing bacteria in subordinate phase, and their kind is less relatively, and the matrix that can utilize is also very limited, and reproduction speed is very slow, and the doubling time is generally at tens hours, the longest 4～6d that reaches.In addition, methane-producing bacteria receives environmental factors, and is bigger like the influence of pH value, temperature, hazardous and noxious substances or inhibitory substance etc., much more responsive than the bacterium of fs.
Keep traditional single-phase anaerobic reactor normally, efficiently the operation; Just must in a reactor drum, keep the balance between the bright different bacterium of above-mentioned two class features; To guarantee out that promptly the products such as organic acid that fermentation and acid formers produce can be utilized and finally be converted into inorganic end products such as methane and carbonic acid gas timely and effectively by methane-producing bacteria; Otherwise, will cause organic acid accumulation in the reactor drum, will cause the decline of pH value in the reactor drum when serious; The decline of pH value; Again can be further the activity and the metabolic capacity of methane-producing bacteria be had a negative impact; Even can cause serious restraining effect; Further reduce its conversion and consume the organic acid ability: because the decline of pH value is such serious to what methane-producing bacteria produced not as it to the disadvantageous effect of fermenting and acid formers produces; This mainly is because the different qualities of two above-mentioned bacterioids determines; Even the pH value therefore in reactor drum drops to when to a certain degree causing the more serious inhibition of methane-producing bacteria, to ferment and the activity of acid formers still might also not be a greater impact, they also can continue the organism in the raw wastewater is converted into organic acid; So will cause even more serious organic acid accumulation and the decline of pH value greatly, and the even more serious restraining effect to methane-producing bacteria; In fact; A process like this is exactly the process of anaerobic reactor appearance so-called " acidifying phenomenon "; The experience of many actual motions is told us, in case the butyric acid phenomenon appears in anaerobic reactor, wants it is recovered normal just very difficult; One side and need the technology and the experience of very high operation anaerobic reactor also needs the relatively long time on the other hand; Therefore in some actual engineering; In case " acidifying phenomenon " appearred in anaerobic reactor; Under the situation of condition permission, operator would rather all abandon the mud in the reactor drum, add seed sludge, cultivation domestication again again; A lot of facts explain that all this scheme is also shorter sometimes than the needed time of making great efforts to resume operation on the original basis.Thus. we can find out, keep in traditional single-phase anaerobic reactor that Qu Pingheng is not a nothing the matter between fermentation and acid formers and the methane-producing bacteria.
In addition; Because methane-producing bacteria will be far above fermentation and acid formers to the requirement of envrionment conditions; And the growth velocity of methane-producing bacteria is also far below fermentation and acid formers; Therefore we are when moving traditional single-phase anaerobic reactor. and all be at first to select operational conditions, but also can take numerous and diverse measure to come to keep balance between the two as far as possible according to the requirement of methane-producing bacteria.Though a kind of control strategy of moving like this can guarantee at first that the normal ox of ending of methane-producing bacteria is long and bring into play its normal metabolic function; But can affirm that this is for fermentation and acid formers and the flora that belongs to the kinds such as hydrolytic bacteria of fs bacterium equally; Just be not necessarily its righttest growing environment condition and the condition that can bring into play its metabolic function best; But because their adaptive faculty is strong, growth velocity is also very fast; Even be not to be under the optimum condition therefore, they still can bring into play its metabolic function more fully.Therefore, we can say,, sacrificed the partial function of fs bacterium to a certain extent, can be in best envrionment conditions to guarantee methane-producing bacteria at the operation towel of traditional single-phase anaerobic reactor.Usually hydrolysis, fermentation, product acetate three phases are summed up as and produce sour phase, will produce methane phase and be summed up as product methane phase.To combine in a reactor drum producing the acid phase and producing methane traditionally, but produce sour phase and produce methane, and need different dominant bacterias, so control the dominant bacteria difficulty mutually to different reaction requirements.
