Description
Technical field
The present invention relates to a kind of sewage disposal device, belong to technical field of sewage.
Background technology
First anaerobic baffled reactor (Anaerobic BaffLted Reactor is called for short ABR) technique equaled the anaerobic sewage biological technology of a kind of new high-efficiency of development on the basis summarizing various s-generation anaerobic reactor treatment process feature performance in 1981 by the McCarty of stanford university of the U.S..Owing to using a series of vertically arranged traverse baffle in the reactor, reactor is separated into several reaction chambers of series connection, each reaction chamber can regard a relatively independent upflow sludge blanket system (upfLow sLudge bed is called for short USB) as.Processed waste water makes current downflow along traverse baffle in reactor, and successively by the Sludge Bed of each reaction chamber, the organic substrate in waste water is removed by contacting with microorganism.Make the microbial solid in reactor expand up and down in each compartment that traverse baffle is formed and precipitate motion by means of the gas produced in reactor in treating processes, the current in whole reactor then make horizontal flow with slower speed.Current make the total length that flow through of current in reactor increase around traverse baffle flowing, and the stop of traverse baffle and the settlement action of mud in addition, biosolids is trapped in reactor effectively.Therefore the hydraulic flow state of ABR reactor is closer to pulling flow type.Secondly because traverse baffle forms separately independently compartment in the reactor, therefore each compartment can according to entering the difference of substrate and the stability of turning out with corresponding treatment effect and operation.The microflora adapted to, thus cause anaerobic reaction produce acid mutually and methanogenic phase obtain along journey and be separated, make ABR reactor on overall performance, be equivalent to an antibiotic wastewater, achieve the separation of phase.Finally, the biogas that each compartment produces can discharge separately by ABR reactor, thus the gas avoiding the generation of anaerobic process different steps mixes mutually, especially the H2 produced in acidization can discharge in advance, and being beneficial to the mesostate such as propionic acid, butyric acid in the methane phase stage can divide pressure to transform smoothly at lower H2.ABR reactor is equivalent to a diphasic anaerobic treatment system on overall performance.It is generally acknowledged, diphasic anaerobic technique is by producing acid mutually and being separated of methanogenic phase, and two large class anaerobic bacteria floras can grow under optimum envrionment conditions separately, are conducive to the activity giving full play to anaerobic bacteria flora, the raising treatment effect of system and the stability of operation.
There is following problem through running discovery in existing anaerobic baffled reactor, in order to ensure certain current and aerogenesis lift velocity, ABR reactor can not be too dark, and how water inlet is uniformly distributed also is a problem.Compared with single-stage UASB reactor, first lattice of ABR reactor have to bear the localised load much larger than mean load, this may cause the decline of processing efficiency, find that the existing impact load resistivity to hc effluent is not strong through running, answer active sludge in device to have depositional phenomenon, hydraulic mixing is uneven.
Summary of the invention
Object of the present invention is exactly for above-mentioned the deficiencies in the prior art, provides a kind of running maintenance convenient, a little repair, the new and effective anaerobic biological reactor that treatment capacity ability is large.
The technical solution used in the present invention is as follows:
A kind of new and effective anaerobic biological reactor, it is characterized in that it includes reactor body, the side of described reactor body is provided with lateral inflow water distributor, in reactor body, each flap reactor lower part is provided with lower support bed, lower support bed is provided with flowing biologic packing material layer, upper limiting layer is provided with above flowing biologic packing material layer, in described reactor body, the top of each flap reactor is equipped with pulse water distributing device, the reactor effluent weir water outlet of reactor body is connected with backflow pump intake, and backflow pump outlet is connected with described pulse water distributing device.
The reactor bottom being in most end in described reactor body is provided with mud collection tube, and described mud collection tube is connected to described each flap reactor by sludge pump.
Described lower support bed is the waffle slab that anticorrosive material is made.
Described upper limiting layer is the waffle slab that anticorrosive material is made.
Beneficial effect of the present invention has:
Solve to ensure certain current and aerogenesis lift velocity, ABR reactor can not be too dark.How water inlet is uniformly distributed this problem.Because adding the effluent recycling of ABR reactor, first lattice can bear the localised load much larger than mean load, add the impact load resistivity of reactor, active sludge in reactor is made to there will not be depositional phenomenon owing to adopting pulse water distribution reactor, increase the effect that fixed bed flowing filler makes to be formed in each reactor three phase separation, to liquid, gas and solid sludges are all separated in fixed bed flowing filler, make to form independent mud living environment in each reactor, form three different stepss of anaerobic reaction, the i.e. acidication stage, the hydrogenesis and acetogenesis stage, the methane phase stage, improve the starting efficiency of anaerobic reactor, by adjusting the size of pulse water distribution flooding quantity in each reactor, hydraulic mixing in each reaction chamber can be made to change, thus the water-power environment better created needed for each elementary reaction of anaerobic reaction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in Figure 1, the present invention it include reactor body 10, the side of reactor body 10 is provided with lateral inflow water distributor 1, and sewage enters in flap reactor through lateral inflow water distributor 1.In reactor body 10, each flap reactor lower part is provided with lower support bed 2, the waffle slab form that lower support bed 2 is made for anticorrosive material.Lower support bed 2 is provided with flowing biologic packing material layer 3, is provided with the upper limiting layer 4 that the biologic packing material that prevents from flowing runs off above flowing biologic packing material layer 3, the waffle slab that upper limiting layer 4 is made for anticorrosive material or reticulated flexible filler.In reactor body 10, the top of each flap reactor is equipped with pulse water distributing device 5, and reactor effluent weir 6 water outlet of reactor body 10 is connected with backflow water pump 7 water-in, and backflow water pump 7 water outlet is connected with described pulse water distributing device 5.The reactor bottom being in most end in reactor body 10 is provided with mud collection tube 8, collects the excess sludge in last reactor.Mud collection tube 8 is connected to above-mentioned each flap reactor by sludge pump 9, by sludge pump 9, mud is sent into pulser entrance and makes in the excess sludge reactor be back to before it alive.
When the present invention runs sewage from the side water inlet distributor 1 enter in reactor body 10 uniformly, sewage passes through the biological bed of flowing from reactor, after the biological bed that flows, sewage enters in next reactor, and arrive reactor bottom by flap, enter in next reactor from reactor bottom through the biological bed that flows, in the end reactor has effluent weir by part effluent recycling to pulse water distributing device import, is stirred in reactor by pulse water distributing device.Increase mud collection device under last reactor, enter collection to anaerobic sludge, mud is back to use in reactor above or outer row by combined process operation.
The present invention mainly designs for high-concentration waste water, by strengthening the quantity of reflux of water outlet, reducing water water quality to the impact of reactor, controlling the mud age of reactor by increasing sludge back flow quantity.
Other the undeclared part that the present invention relates to is same as the prior art.
