Description
Technical field
The present invention relates to a kind of deflector anaerobic reactor, apply the waste disposal plant of this reactor, particularly be applicable to the waste disposal plant of breeding wastewater.
Background technology
Anaerobic biological treatment claims again anaerobic digestion, and being under anaerobic has the multiple-microorganism acting in conjunction, makes organism generate CH
4, CO
2Process.
Before the sixties, the process that it is believed that digestion is two stages, first stage claims fermentation stage or claims to produce acid phase, the organism of insoluble complexity first is hydrolyzed under the anaerobion effect in this stage, then be converted into simple organism, as lipid acid, alcohols, carbonic acid gas and hydrogen etc., the microorganism that this one-phase works is through being called fermenting bacteria or acid formers, subordinate phase is called produces the first a heatable brick bed stage, by the bacterium that produces the first a heatable brick bed, the product of first stage is converted into to CH in this stage
4, CO
2.
At the end of the seventies, people have proposed the three-stage theory of anaerobic digestion.First stage is called hydrolysis, fermentation stage, identical with aforementioned two stage theories, it is also the process that complicated organism is hydrolyzed and ferments under the effect of microorganism, polysaccharide first is hydrolyzed to monose, by the glycolysis approach, further be fermented into ethanol and lipid acid again, as propionic acid, butyric acid, lactic acid etc., protein first is hydrolyzed to amino acid and through deaminizating acid effect, produces lipid acid and hydrogen again.Subordinate phase is called produces hydrogen, produces the acetic acid stage, is to be referred to as to produce hydrogen, acetogen by the special bacterium of a class, and the lipid acid such as propionic acid, butyric acid and ethanol etc. are converted into to acetic acid, hydrogen, CO
2.Phase III is called the first a heatable brick bed stage of producing, and utilizes acetic acid and hydrogen, CO by producing first a heatable brick bed bacterium
2Produce methane.Research shows in the anaerobic biological treatment process that the decomposition of 20% methane from acetic acid all arranged, and all the other originate from hydrogen and CO
2Synthetic.
Deflector anaerobic reactor (Anaerobic Baffled Reactor, be called for short ABR), also referred to as anaerobic baffled reactor, that a series of vertical placements are set in reactor baffle moves waste water along the upper and lower baffling of baffle in reactor, lead to successively the Sludge Bed of each lattice chamber, limit until export, the organic substance in this process in waste water fully contacts and is removed with anaerobic activated sludge.The multiple advantages such as that the ABR reactor has is simple in structure, sludge retention ability epistasis height.
As shown in Figure 1, tradition ABR's is simple in structure, on the whole closer to pulling flow type, do not need filler and baroque triphase separator, the physical structure that makes ABR that adds of vertical baffling plate has had agitating function (baffling up and down repeatedly), strengthened contacting of anaerobic activated sludge and matrix, under the condition of the constancy of volume, increased the flow process of waste water, touch opportunity and the duration of contact of matrix and mud are increased, improved the processing efficiency of reactor, anaerobic activated sludge in reactor rises and sinks by means of the flow feature of waste water and the aerogenesis in degradation process, but the settleability with mud self that stops due to traverse baffle, mud is very slow along the translational speed of reactor level direction, the width of each upward and downward lattice chamber does not wait in addition, therefore a large amount of celebrating oxygen activity mud are left in reaction, can in the apposition chamber, not inoculate and culture out and the sewage quality of this lattice chamber of flowing through and the microflora that envrionment conditions adapts, make the operation of reactor more stable, flexibly and effectively.
At present the improvement of ABR reactor focused mostly in the stop of strengthening anaerobic sludge, make inlet distribution even.Initial ABR design is shown in Fig. 2 (A), upward flow chamber in this reactor and lower to the stream chamber, be wide, traverse baffle add the stop that has strengthened mud, improved processing efficiency, many lattice cell structure makes reactor become pulling flow type, more acceptant material is provided for product first a heatable brick bed bacterium.The people such as Bachmann (Bachmann A, Beard V L, McCany P L, Performance characteristics of the anaerobic baffled reactor, J.Wat.Res., 1985, 19 (1): 99-106) ABR has been done to the improvement as shown in Fig. 2 (B), lower to stream chamber narrow down, the upward flow chamber is widened, being conducive to anaerobic sludge, to rest on upward flow indoor, make reactor become the upflow sludge blanket system, water (flow) direction is consistent with the aerogenesis ascent direction, strengthened the stirring action to the mud bed, be conducive to fully contacting of microorganism and matrix, the flap edge is turned up and is guided water inlet into the Liu Shi center to promote mixing, help to realize the homogeneity of water distribution.As a rule, the whole upward flow chamber of ABR is wide, whole lower to the stream chamber, be also wide, upward flow chamber and lower width to the stream chamber are than generally in the scope of 1: 1 to 4: 1.
Yet, the sewage charging of high density causes through the Room the 1st, 2 (particularly Room the 1st) of the ABR that is everlasting that supernatant liquid filtering speed slows down, the COD clearance reduces, volatile acid concentration raises and the problem such as sludge bulking floating, thereby affected the normal operation of ABR, the further raising of the sludge concentration of restriction.Simultaneously, for maintaining the upflow sludge blanket system, the flow velocity of each chamber mixed solution also is subject to certain restrictions.
At present, gradually to intensive future development, for the ease of transportation and storage, plant is generally all in big city periphery development along with the livestock culture industry.It is high that aquaculture wastewater (hen house, pig house washing water and diary farm milk workshop wash-down water) all has an organic concentration, suspended substance is many, sewage is concentrated, amount is large and the characteristics of difficult treatment, has brought immense pressure to surrounding enviroment, becomes the restraining factors of aquaculture to intensivization development.Therefore, these waste water need to be carried out to effective disposal and utilization.
Modern plant adopts dry clear excrement mode to process solid manure to reduce wash water amount and processing cost, and the materials such as residual ight soil, feed, milk, sterilizing agent enter the breeding wastewater that plant produces mostly.Breeding wastewater adopts the separating dry space from moist space technical finesse usually, when the waste water that contains a large amount of solid matters after separating dry space from moist space machine extruding, the solid residue separated needs stabilization treatment, and the waste water that does not substantially contain solid residue still has the further processing of quite high concentration needs.
Chinese utility model patent CN201777963U discloses a kind of plant's solid-liquid combined sewage disposable processing set that is applicable to, comprise three grades of deflector anaerobic ponds, biological contact oxidation pond, settling tanks and recycle pond, the settling tank in the future active sludge in autoxidation pond separates and is back to first step deflector anaerobic pond and stablizes, and stable mud is by second and the discharge of third stage deflector anaerobic pond.
To sum up, the waste disposal plant that still needs at present improved deflector anaerobic reactor and be applicable to various sewage chargings (particularly breeding wastewater).
