Description
Technical field
The utility model belongs to technical field of sewage, is specifically related to a kind of spiral lift flow type sewage reaction unit.
Background technology
Current, aspect sewage disposal, domestic and international many experts and scholar are to treatment technology, be that aspect researchs such as the microorganism dynamic characteristic that carries out biochemical reaction, inner reaction mechanism and the operation that reaches efficient clearance and reaction conditions are more, but lack reaction technology, promptly to the research of the aspects such as reactor optimization design of binding kinetics.The reactor theory thinks that chemistry or biochemical reaction go to finish by reactor.If reaction technology is not advanced, the good again expected effect that also do not reach of technology.Reaction technology depends on the fluidised form in the reactor.Common reactor types can be divided into four classes: batch reactor (Batch Reactor, BR), continuous stirred tank reactor (Continuous Stirred TankReactor, CSTR), stepwise CSTR (CSTR Cascades), piston flow (i.e. " plug-flow ") reactor (Plug Flow Reactor, PFR) etc.BR reactor and PFR reactor are owing to have time or space plug-flow fluidised form, and concentration gradient is big, thereby reaction effect is better.But consider the influence factors such as stoppage time of batch reactor, the reaction efficiency of reactor with PFR for the highest.For SBR series, though its unit process belongs to the BR reactor, has concentration effect preferably, but the mode of its intermittent operation is unfavorable for engineering and uses, and the Inlet and outlet water mode is improved the back (as the ICEAS technology, for continuous feeding and intermittent goes out water condition), change the characteristic of BR reactor again to a certain extent, thereby influenced reaction efficiency; And to A
2/ O series, the mode of its Continuous Flow help engineering to be used, but its unit process belongs to the CSTR reactor basically, and reaction efficiency is lower.Some reactors are subjective wants to be designed to pulling flow type though have, and as oxidation ditch etc., because the pond fluidised form feature under horizontal condition, in fact back-mixing is more serious, influences reaction effect.The reactor of sewage disposal is actually bio-reactor, and survival condition of microorganism and flow-shape have confidential relation in the reactor, and stable plug-flow fluidised form helps symbiosis and the alternate of microorganism.Obviously, if each unit process of present sewage disposal (comprising dephosphorization denitrogenation) technology can both make corresponding biochemical reaction finish comparatively completely, then aforesaid Technology will obtain better effect, and technical process and reactor volume also can shorten and reduce widely, and treatment effect also can increase substantially.
The technology the most relevant with the application is the deep well aeration activated sludge process, and this technology and traditional activated sludge process are similar, just for the utilization ratio that improves oxygen the depth of water increased, from reaction technology new breakthrough not.On the one hand, from reactor types, do not form this feature of pulling flow type; On the other hand, only consider the mass transfer of oxygen, do not considered the mass transfer between other matrix and the active sludge.Thereby the deep well aeration activated sludge process is limited improving on the processing efficiency.
Summary of the invention
The purpose of this utility model is the defective at the prior art existence, designs a kind of elevating screw bioreactor that can really form the pulling flow type reaction, makes active sludge intermixture from bottom to top spiral rising in cylindrical reactor, improves water treatment efficiency.
The technical solution of the utility model is as follows: sewage disposal elevating screw bioreactor, form by anaerobic reactor, anoxic reacter, aerobic reactor, settling tank and with the pipeline that they are connected in turn, each pipeline is inserted the bottom of next reactor successively by the top of a last reactor, water inlet pipe is inserted by the anaerobic reactor bottom, and rising pipe is picked out by settling tank top; Be provided with the water conservancy diversion spiral propeller in each reactor, as have the vane type spiral whipping appts at certain inclination angle.
The anoxic reacter of above-mentioned reactor and water outlet place of aerobic reactor are connected to return line, tap into water inlet place of last reactor respectively.The bottom of settling tank also is connected to return line in addition, connects water inlet place of anoxic reacter.
The working process of reactor is: water inlet enters the anaerobic reactor bottom with the mixed solution that refluxes from anoxic reacter after metering, the mixed solution of anaerobism end enters the anoxic reacter bottom with the mud that refluxes from settling tank and from the mixed solution that aerobic reactor refluxes, the mixed solution of anoxic end enters the aerobic reactor bottom, the mixed solution of aerobic end enters settling tank and carries out mud-water separation, and the supernatant liquor of settling tank is the water outlet of system.Mixed solution is in anaerobic reactor, anoxic reacter and aerobic reactor, and under the promotion that specific inclination angle water conservancy diversion spiral propeller is arranged, spiral rises.
Advantage of the present invention is as follows:
(1) spiral up-flow feature makes the form of reactor approach pulling flow type, makes sewage form stable spiral upper upstream in reactor.Because " helical flow " is the mode along the circumferential direction spiral rising of streamline with " plume ", thereby the length-to-diameter ratio of " plume " is very big, the length-to-diameter ratio of reactor then can be smaller.This has just improved the capacity utilization of plug-flow fluidised form stable in the reactor of being convenient to the engineering application greatly.
(2) this structure can this kind fluidised form also can make the certain velocity slope of generation between the adjacent streamline in order to the mass transfer between the system, help forming and maintaining relatively-stationary microflora, make and produce common, alternate ecological relationship between the microorganism, and then performance acts synergistically between microorganism, make full use of the various nutritive substances in the sewage, treatment effect is efficiently stablized.
(3) compare with traditional plug flow reactor, the shearing force that spiral water flow produced of Spiral Up-Flow Reactor System can reduce the thickness of liquid film, reduces resistance to mass transfer; Simultaneously, the centrifugal inertia of spiral water flow can make mud flco and organic particle make the radial motion line to make the mass transfer effect of material wherein better.Therefore, the spiral water flow of SUFTR system can improve organic mass transfer velocity effectively, and then has improved the processing efficiency of system.
(4) spiral up-flow feature can form many environmental changes " interlocking area ", according to " fringing effect " in the ecology, in the common biology community structure complexity of the interlaced area of changeable environment, is easy to occur multiple biological coexistence phenomenon.Thereby Spiral Up-Flow Reactor System helps the variation of microorganism in the active sludge, can form complicated and stable microbial ecosystem, and anti-external interference and self-recovery regulating power are stronger.
