Description
Technical field
The utility model relates to a kind of anaerobic biological technical finesse sewage apparatus.
Background technology
Since the present seventies in 20th century, the anaerobic waste water treatment technology is because of it has reduced investment, working cost is low and can produce the energy characteristics such as (biogas) that can invest recycling, and developed faster, and to have occurred a collection of be s-generation anaerobic reactor treatment technology representative, that can be detained a large amount of microbial solids with up flow anaerobic sludge blanket reactor (UASB), the interception capacity to microorganism that this batch reaction device is had makes the volume of reactor reduce greatly, and processing power and treatment effect are greatly improved.And at present, also there is certain problem in some aspects in these technology or waits further further investigation.Key problem in technology as UASB is the appropriate design of triphase separator and successfully turns out well behaved granule sludge, but the design of domestic triphase separator also lacks sophisticated method; The cultivation of granule sludge still is in the conceptual phase that deepens continuously.Another of UASB is the into restriction of suspended solids (SS) content in the water, in case the contained TS concentration of sewage that enters in the reactor surpasses 4000-5000mg/L, can't normally move.Often need strict pre-treatment measure, to reduce the SS concentration in the water inlet.In operational process, also be subjected to simultaneously temperature, pH, the isoparametric strict control of redox potential.
Because the existing problem of s-generation reactor has influenced applying of they to a certain extent.For this reason, study, develop and developed anaerobic baffled reactor (ABR).
From textural, ABR is by built-in vertical flow deflector, and reactor is separated into placed in-line several reaction.During operation, one by one by the mud bed in the reaction chamber, and the stirring action by current and aerogenesis makes that the substrate in the water inlet fully contacts and the removal of being degraded with microorganism to mud under the effect of traverse baffle.On technology, at first UASB can be similar to and regard a kind of complete mixing reactor as, and ABR is a kind of COMPLEX MIXED type waterpower fluidised form, and more approaches plug flow reactor.Microorganism among the ABR in each reaction chamber is mutually with flow process alternation step by step, and the rule of alternation is in degradation of substrates process coordinating unanimity, thereby guarantees that corresponding microorganism has best work activity mutually.But, find that there is following defective in first-generation ABR reactor along with the practice of engineering:
(1) sludge concentration is low
(2) suspended sludge runs off easily, exists when especially current change to run the mud phenomenon
(3) do not return liquid separating apparatus
(4) because the low processed in units rate of sludge concentration is low, so the corresponding increase of the big cost of structures volume.
Summary of the invention

Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of present anaerobic baffled reactor (ABR).
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, it is made up of the utility model a plurality of reaction chambers 1 of serial connection mutually, the reaction chamber 1 that is positioned at high order end be provided with water-in 2 by the lower end, 1 of the reaction chamber that is positioned at low order end is connected with solid-liquid separator 3.Solid-liquid separator 3 is that a non-distance is described device, is provided with water outlet 4 at an upper portion thereof, and the sewage after the separating treatment is discharged from water outlet 4.Be provided with mud bypass outlet 5 in the bottom of solid-liquid separator 3, the mud backflow import 6 at it and each reaction chamber 1 top is connected, mud in the solid-liquid separator 3 after the separating treatment is back to each reaction chamber 1 top from mud bypass outlet 5, enter the reaction chamber 1 from the mud backflow import 6 at reaction chamber 1 top, continue to participate in reaction, realize denitrification, reach the purpose of denitrogenation.Top at each reaction chamber all is provided with filler 7, and filler 7 is the crotch structure, and its material is hydrophilic engineering plastics.Can prevent the loss of mud, and on filler 7, can form microbial film, increase biomass, improve organic degradation rate.Each reaction chamber 1 is to be separated by traverse baffle 8 in the utility model, variation according to the waterpower fluidised form, can regulate the spacing of each traverse baffle 8, the lower end of traverse baffle 8 is apart from reactor 1 bottom one segment distance, flow pass as sewage, and traverse baffle 8 lower ends tilt to the water outlet direction, to influence the waterpower fluidised form.Each reaction chamber 1 top of the utility model is equipped with collection and confinement of gases mouth 9, and the gas that produces in the reaction chamber is collected separately by lattice, is convenient to study respectively the dynamic of each reaction grid chamber.
The utility model adopts the method for natural membrane before bringing into operation, former water enters the digested sludge of getting municipal wastewater treatment plant behind the reactor and is poured in the reaction chamber by each reaction chamber top respectively, digested sludge is sunk under action of gravity, be subjected to the obstruct of 3-D filler in the reaction chamber in the sinking process, brown mud flco overworks filler in the compartment space of reaction chamber, control flooding quantity subsequently, the mud of 3 days postadhesion on the filler of top begins whiting, biological floe that filler is hung gradates from top to bottom and is oyster white acidifying bacterium, be covered with oyster white acidifying bacterium after 7 days on the first compartment filler, most brown active sludge flcos can drop down onto the bottom on last compartment filler, only hang with a small amount of oyster white acidifying bacterium on the filler, shorten dwell time of sewage then gradually, strengthen flooding quantity, finish substantially to the 14th day each reaction chamber biofilm.But biomass successively decreases from first compartment, and biofilm development degree difference, and the parcel filling fibers that has is rounded, and the microbial film main body that has is suspension type.So far the utility model just can normal operation input.
The utility model anti impulsion load can adapt to bigger temperature variation, and control minimum temperature in service is one and guarantees that reactor normally moves, guarantees to handle back water outlet underlying condition up to standard.Owing to increase filler and equipment for separating liquid from solid, make device have ability and the good solid-liquid separation performance of good delay microorganism, its microbial quality concentration can reach 50-70g/L, there is microbial environment in the baffling contact precipitation integral anaerobic reactor to have biological preferably grating again and forms that good population cooperates and good heavy journey distribution, impact load adaptability during to the variation of water quality and quantity is strong, so the utility model has good prospects for application for handling flow and the bigger trade effluent of change in concentration.
The plug-flow state of lattice structure of the present utility model and current makes F/M reduce gradually with current, and the lattice chamber F/M after arriving more is low more, helps solid-liquid separation more, so can guarantee good effluent quality.And can by changing the spacing of traverse baffle, regulate hydraulic detention time, even can also carry out gap operating according to the difference of water quality and quantity, satisfy the effluent quality requirement.Simultaneously, the utility model can also carry out the aerobic operation of anoxic in that appropriate reaction chamber lattice are indoor, to reach the purpose of denitrogenation in same reactor.
