Compared with the prior art, the spiral type bioreactor has the advantages of simple operation, good turbulent motion degree, good mass transfer efficiency and easy control, not only can be completely mixed on the flowing cross section, but also has the slower concentration gradient in the flowing direction, and can be used for deep biochemical treatment of various sewage.

Description

Spiral bio-reactor
Technical field
The utility model belongs to technical field of sewage, is specifically related to a kind of plug flow biochemical reaction device, and this device can be used for the treating processes of trade effluent and sanitary sewage and percolate, is mainly used in the processing that contains the ammonia nitrogen containing wastewater from catalyst.
Background technology
In recent years, along with development of industry and agriculture, to trade effluent (as refinery water, containing wastewater from catalyst, synthetic ammonia waste water), the emission limit set of diffusion water of garbage burying ground and sanitary sewage is more and more stricter, sewage disposal technology more and more comes into one's own, particularly more to aspect researchs such as the operation of the dynamic characteristic of microbial biochemical reaction, inner reaction mechanism and efficient clearance and reaction conditionss, having only reaction technology with good technology and advanced person to combine for sewage disposal just can the good treatment effect of the amount of reaching.
Fluid distribution and flow state in the reactor have a significant impact reactivity worth.Batch reactor (Batch reactor, BR) and plug-flow reactor (Plug flow reactor, PFR) owing to have time and space plug-flow fluidised form, thereby reaction effect is better, but consider the influence factors such as stoppage time of batch reactor, then reaction efficiency is high with PFR.Have good concentration effect though belong to the unitary SBR serial reaction of BR device, its intermittently operation scheme be unfavorable for that engineering uses.A 2Though/O serial reaction device belongs to the mode of Continuous Flow and helps the engineering application, its unit belongs to continuous stirred tank reactor basically, and (Continuous stirred tank reactor, CSTR), reaction efficiency is lower.The oxidation ditch reaction formation is pressed the pulling flow type design, but in fact back-mixing is still relatively more serious, thereby has influenced reaction effect.Existing inside circulation triphase fluidized bed water treatment device is owing to simple in structure, mass-transfer performance better are used widely, but because a reaction inner core only is installed on the bed body, this device is because cross section of fluid channel is big, make that interior oxygen transfer of unit volume unit time is abundant inadequately, cause speed of reaction lower.
A kind of compound internal circulation biological reactor has been proposed among the CN1478732A, its feature is to be provided with three circulation inner cores in the bed body of closed bottom, though this structure has solved the full back-mixing of monotubular, problem that mass-transfer efficiency is low to a certain extent, after amplifying, this reactor still exists and the same problem of monotubular reactor.Sewage-treating reactor is actually to microorganism provides a living space, and this is suitable for the stable of microorganism existence and gas-liquid distribution uniformly and back-mixing fluidised form with regard to needing to have in the reactor.Though the full back-mixed reactors mixed effect of continuously feeding formula is fine,, cause a part of pollutent just to be discharged from, the therefore requirement that does not reach super deep removal pollutent without abundant degraded because device internal contamination substrate concentration is even.
CN1454855A has proposed a kind of elevating screw bioreactor, and its principal character is provided with spiral up-flow equipment exactly in vertical reactor, and water-in and water outlet are located at the bottom and the top of reactor respectively; Spiral up-flow equipment wherein is the water conservancy diversion spiral propeller.Though this reactor provides the plug-flow fluidised form environment that helps microorganism coexistence and alternate, but because thruster needs motor to drive, the additive decrementation energy, and for aerobic microbiological, be unfavorable for the uniform distribution of oxygen in reactor from the sidewall aeration, and then influence the processing efficiency of reactor.
Therefore needing on a kind of flow cross section can thorough mixing, have the reactor of slow concentration gradient on the flow direction again, if all helping biochemical reaction, each unit process of sewage treatment process finishes comparatively completely, then good Technology will be brought into play better effect, and greatly shortened process, reduce reactor volume, increase substantially treatment effect.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of simple to operate, less turbulence good, mass-transfer efficiency is high, can thorough mixing on manageable a kind of flow cross section, have the multi-layer helical formula reactor of slow concentration gradient on the flow direction again.
The spiral bioreactor construction of the utility model is for being provided with vertical multi-layer helical plate in reactor, form the multi-layer helical passage, the helical channel bottom is provided with gas distribution pipe, and the reactor water-in is arranged on the center of multi-layer helical passage, and the reactor water outlet is arranged on the edge of multi-layer helical passage.
The spiral bio-reactor of the utility model can be made by materials such as metal, synthetic glass or resins, and the reactor profile can be a suitable shape such as cylindrical or cube shaped, and the bottom is provided with coil tube type air gas distribution pipe.
The reactor of this structure can make sewage form local back-mixing state earlier in reactor, discharge by the long and narrow water channel of being arranged to by the spiral tube gradually then, this compares with full back-mixed reactors and helps super deep removal pollutent, simultaneously the reactor of this structure can provide a kind of living environment of stable plug-flow fluidised form for microorganism, help fully contacting of biological and pollutent and gas, guarantee excellent mass transferring performance, improved treatment effect greatly.The spiral bio-reactor of the utility model can be used separately, perhaps a plurality of spiral bio-reactor applied in any combination, the bio-reactor applied in any combination of perhaps spiral bio-reactor and other type.
The spiral bio-reactor of the utility model also has following special advantage except advantage such as capacity utilization height, " plume " length-to-diameter ratio with plug flow reactor be big:
(1) the plug-flow fluidised form of this reactor formation does not need thruster, need not other power set in the reactor, mainly relies on aeration mixing, action of gravity gravity flow, can reduce the part energy consumption like this.
(2) this reactor all adopts the bottom aeration, has guaranteed effective utilization of space reactor like this, and it is more abundant that solid-liquid gas three-phase is mixed.
(3) the formed long and narrow water channel of this reactor can increase substantially aeration and mass-transfer efficiency, and radially back-mixing is more abundant, and the deficiency of avoiding full back-mixing to exist makes pollutent can surpass advanced treatment.
