Description
Technical field
The utility model relates to a kind of integrated internal circulating anaerobic sewage sludge reactor, belongs to the wastewater treatment equipment technical field.
Background technology
Existing anaerobic treatment not only requires dwell time of sewage long, and the influent quality water yield that will aspire for stability fully contacts solid-liquid to guarantee the stirring to mud.The output of the upflow velocity of liquid, biogas all can have influence on the mixing of muddy water in the reactor simultaneously.After the water distribution system of reactor has been determined, if under cold condition, move, or, or handle the organic waste water of low concentration, or when the water yield changes greatly in producing initial start stage (can only under underload, move), since can not produce a large amount of biogas than strong disturbance, therefore, the reactor mixed effect is relatively poor, thereby short stream occurs, improve troubled water if improve the hydraulic load of reactor, then sludge loss can occur.Therefore, original anaerobic treatment is long start time, and mud runs off easily, poor processing effect, and anti impulsion load not causes the deposition of SS in the waste water easily, is not suitable for the high waste water of treatment S S etc.
Summary of the invention
At the deficiencies in the prior art, it is a kind of reasonable in design that the utility model provides, simple in structure, easy to manufacture, the ability of holding back microorganism greatly strengthens, and it is higher to remove efficient, and it is fast to have toggle speed, adaptive faculty is strong, processing efficiency height, stable integrated internal circulating anaerobic sewage sludge reactor.
A kind of integrated internal circulating anaerobic sewage sludge reactor, be built-in with taper mud-water separation groove on the top of reactor, the inside of this taper mud-water separation groove is provided with mud mouth, shore pipe, biofloculation district, compounded mix floor and effluent trough successively, mud mouth is arranged on the bottom of taper mud-water separation groove, and effluent trough is arranged on the top of taper mud-water separation groove.
Described taper mud-water separation groove is arranged on a side of reactor internal upper part.
After sewage entered reactor, because the mud thorough mixing that makes in sewage and the reactor is stirred in the pressure of bottom, agitator made the muddy water in the reactor have certain flow velocity, prevents the deposition of SS in the reactor.Sewage after the processing enters taper mud-water separation groove by the prosopyle that is located at taper separator tank bottom, compounded mix in the taper mud-water separation groove is blocked in mud in the taper mud-water separation groove, realize mud-water separation, the mud that stops is fallen back in the reactor by the bottom mudhole of taper mud-water separation groove, mix with the sewage in the reactor, guarantee the sludge concentration in the reactor; By the clear water that compounded mix is separated, discharge reactor through discharging device.Be characterized in equipment for separating liquid from solid is built in the reactor, and in taper mud-water separation groove, compounded mix be set, force mud-water separation, prevent sludge loss, prolong sludge retention time.
Integral anaerobic reactor has been strengthened stirring action to the mud bed by built-in pump circulation, helps the abundant contact of microorganism with the water inlet pollutent, helps the formation of granule sludge.A side is provided with taper mud-water separation groove in the reactor, sheaf space sets up compounded mix on taper mud-water separation groove, has double-deck effect, it can hold back suspension microorganism on the one hand, realize solid-liquid separation, prevent the microorganism loss, microorganism mud is present in the reactor in the relative fixed mode, the microbial biomass of reactor unit volume is higher, and sludge retention time is longer.Integral anaerobic reactor can bear higher hydraulic load, has improved the removal efficient of COD.Integral anaerobic reactor can maximally utilise volume, reduces floor space, and the ability that reactor is held back microorganism greatly strengthens, and it is higher to remove efficient; And it is fast to have toggle speed, and adaptive faculty is strong, processing efficiency height, distinguishing feature such as stable.
Integral anaerobic reactor is not only applicable to handle and contains the higher waste water of dissolved organic matter, simultaneously also be suitable for handling and contain the more waste water of SS, by the separation of a side filtrate, SS is come back in the sludge reaction district of bottom, a part is as the core of newborn granule sludge.When reactor moved, the compounded mix layer had the very big ability of holding back biological sludge.Under dynamic action, fully contact with water inlet matrix, make it to grow into fast granule sludge.The microorganism that enters zone more than the filtering layer with current makes mud come back to the Sludge Bed district through the compounded mix separator for mud and water, and clear water is isolated cell body.
Integral anaerobic reactor is not only applicable to handle the waste water that contains dissolved organic matter, also be suitable for simultaneously the lower waste water of treatments B/C, separation by a side filtrate, SS is come back in the sludge reaction district of bottom, be that the interior anaerobic sludge concentration of reactor is higher, help the reaction degraded of reactor internal contamination thing, improve the removal efficient of anaerobic reactor.
Because integral anaerobic reactor has adopted inner pressure to stir, when handling high-concentration waste water, water inlet the very first time under the effect of reactor internally-powered with reactor in the mixed solution thorough mixing, objectionable impurities in the raw wastewater is fully diluted, reduce harmful degree greatly, thereby improved the anti impulsion load ability of reactor.
Integral anaerobic reactor is to establish device for separating mud and water in anaerobic reactor, has realized that spatial effectively utilizes, and has significantly reduced floor space, has obviously saved initial cost.
Integral anaerobic reactor can be established the methane recovery system, and advanced technology is simple and reasonable, and the gas, liquid, solid three phase separation is effective, and water outlet SS content is low, and water quality is good; The maintenance of the equipment maintenance is convenient, the processing efficiency height, and stable and reliable operation, adaptive faculty is strong, is the ideal equipment of anerobic sowage biochemical treatment.
Technology is introduced:
Sewage is through being pumped to Reactor inlet, and water inlet is behind the water distributor water distribution, with mixed solution thorough mixing reaction in the reactor.Although the bottom of the taper mud-water separation groove that is provided with in the mixed solution reactor after the thorough mixing reaction treatment enters the commutating zone of mud-water separation groove, subdue the mixed solution energy.Mixed solution continues to rise, and enters the sludge suspension layer; After the biological sludge flocculation of sludge suspension layer was dammed, mixed solution continuation rising entered the compounded mix district and carries out the mud-water separation processing.Clear liquid after separator for mud and water separates is discharged anaerobic reactor through water-freeing arrangement; Isolated mud falls back to the sludge suspension layer, and a part is back in the reaction zone automatically through the bottom of tapered slope by taper mud-water separation groove.Unnecessary mud is outside shore pipe is discharged reactor.
