Technical field
The utility model relates to a kind of little oxygen biological treatment device of molasses alcohol waste water that utilizes the air oxygen supply.
Background technology
The byproduct molasses of cane sugar manufacture can be used for fermentative production alcohol, give off a large amount of molasses alcohol waste waters in the production process.Molasses alcohol waste water belongs to the high concentrated organic wastewater that is rich in vitriol, is a kind of more unmanageable trade effluent.At present, the molasses alcohol waste water processing mode is mainly contained coagulating sedimentation, evaporation concentration, membrane filtration technique and anaerobism and produce methane etc.Traditional coagulation sedimentation method easily causes sedimentary secondary pollution, and the processing cost height; The byproduct added value that evaporation concentration method is produced is not high, and market is less, has limited the development of this technology; Membrane technique handles thoroughly but processing cost is higher, and the running maintenance complexity, and difficulty is extensively promoted; Owing to there is a large amount of vitriol, the sulfide that bacterial reduction vitriol produces has bio-toxicity, makes methanogen be subjected to severe inhibition, and easily produces secondary pollution in the molasses alcohol waste water.
China's utility model patent " the little oxygen treatment unit of molasses alcohol waste water " (ZL 200720003749.7) is directly to charge into pure oxygen to inside reactor to control little oxygen environment, utilize colorless sulfur bacteria that the sulfide oxidation that sulphate reducing produces is become elemental sulfur, reduce sulfide to producing the influence of methane process, make sulphate reducing bacteria, colorless sulfur bacteria and methanogen be present in device inside simultaneously, realize sulfate reduction, sulfide oxidation, the product methane trinity.In device, directly charge into purity oxygen, the security requirement height, the running maintenance complexity, the use cost of pure oxygen is higher, and therefore difficulty is promoted widely.
Summary of the invention
The utility model purpose provide a kind of simple in structure, processing efficiency is high, security good, simple to operate, the little oxygen biological treatment device of the smart waste water of the mulse that is easy to operational management.
Basic ideas of the present invention: the water outlet of little oxygen reactor is stored in earlier in the bucket that refluxes, air is blasted the bucket that refluxes, redox potential (the ORP of liquid in the control backflow bucket, oxidation reduction potential), again partially liq is back to inside reactor, makes inside reactor form little oxygen environment.Under little oxygen condition, utilize sulphate reducing bacteria with the sulfate reduction sulphidisation, simultaneously, colorless sulfur bacteria becomes elemental sulfur with sulfide oxidation, reduce the inhibition of sulfide to methanogen, in a reaction unit, realize sulfate reduction, sulfide oxidation and product methane process simultaneously, realize the efficient processing of molasses alcohol waste water.
Realization of the present utility model: set up a little oxygen reactor, in reactor, add active sludge, be rich in sulphate reducing bacteria, methanogen and colorless sulfur bacteria in the active sludge through domestication.Reactor lower part is for being that mud district, top are the settling region.
Little oxygen reactor outer setting backflow bucket, little oxygen reactor water outlet enters the bucket that refluxes, and a part effluxes, and a part flow to little oxygen reactor inside by the recirculation water blowback.The redox potential probe is installed in the bucket that refluxes, is monitored the redox potential of liquid in the bucket that refluxes by the oxidation reduction potential control instrument.The aeration head of gas blower is installed in the bucket that refluxes, blower switch is connected with the oxidation reduction potential control instrument, when the liquid oxidation reduction potential is below or above set(ting)value, the oxidation reduction potential control instrument opens or closes gas blower automatically, liquid in the bucket that refluxes blasts air, utilize again the backflow water pump with liquid return to inside reactor, make inside reactor be in little oxygen condition, redox potential is stabilized in certain value.By the reactor effluent recycling, can reduce the concentration load of reactor, conditioned reaction device water inlet carbon-sulfur ratio, controlling reactor interior oxidation reduction potential.
After molasses alcohol waste water enters reactor from reactor bottom, vitriol is reduced into sulfide under the effect of sulphate reducing bacteria, colorless sulfur bacteria becomes elemental sulfur with sulfide oxidation, reduce the restraining effect of sulfide to methanogen, product methane process is carried out smoothly, organism in the waste water is degraded, and produces biogas.
The utility model utilizes the mode of drum air in the bucket that refluxes, again with the liquid return behind the aeration to inside reactor, automatic controlling reactor interior oxidation reduction potential.This apparatus structure is simple, operational safety, convenience, running cost is low, the organic volumetric loading of reactor is big, organic removal rate is higher, both sulfate radical is converted into elemental sulfur in same reactor, reduces the active influence of methanogen, remove the organic pollution materials in the waste water again effectively, and change into biogas.
