Description
Technical field
The invention belongs to sewage treatment fields, and in particular to a kind of brewing spirit high concentration wastewater treatment method.
Background technology
The traditional liquor mode of production is solid state fermentation, and there is production efficiency low consumption grain is big, energy consumption is big, the dirt of generation
It is also big to contaminate object, has data to show, often produces one ton of alcohol, to generate 12-15 tons or so of drunk fish, wherein BOD5Value is
25g/t -30g/t, CODcrValue is 80g/t -120g/t, and liquor production wastewater can be basically divided into high-concentration waste water, low concentration
Waste water.Wherein, high-concentration waste water includes：Distill residual water, drunk fish, fermentation vat Leachate site, library percolating water of going with wine, distillation
Workshop section's flushing water etc., high-concentration waste water main component are yellow water, low-carbon alcohols (ethyl alcohol, amylalcohol, butanol etc.), aliphatic acid, amino acid
Deng.Due to the particularity of liquor industry, according to《Fujian light textile》(the 6th phase of June in 2007, total 21 phase) is introduced, and the country does not have also at present
There are a liquor-making enterprises to have ripe waste water control scheme.The treatment process that several esbablished corporations in the country use at present is such as
Under：
These processing method first stage are that pretreatment includes filtering, gravity precipitation, air supporting, neutralization, anaerobic degradation；Second
Stage is exactly that two stage treatment includes anaerobism, aerobic absorption etc..Using these conventional treatment processes, the big occupation of land of investment is more, and operation is not
Stablize, middle-size and small-size wine brewing manufacturing enterprise is extremely not suitable for.For such case Chinese patent announce notification number be
CN102674615A's《A kind of white wine sewage treatment process》, technique is：The sewage generated from brewing spirit passes through thick successively
The folded wrong formula of fine fack, regulating reservoir, hydrolysis acidification pool, sedimentation basin, up-flow anaerobic sludge blanket, sequencing batch active sludge and spiral
Be discharged after this 7 recipe steps processing of filtration of material, the batch-type sludge and sedimentation basin the two processing steps it
Between have this processing step of sludge reflux, the water outlet of the sedimentation basin enters the up-flow anaerobic sludge blanket after pump is promoted.
This technique is also just with folded wrong formula three works of filtration of material of up-flow anaerobic sludge blanket, sequencing batch active sludge and spiral
The combination of skill flow, also without for the ethyl alcohol, amylalcohol, butanol etc. for accounting for main component in brewing spirit high-concentration waste water,
CODcrAnd BOD5The biochemical that high special circumstances focus on treatment process is good, ignores treatment process to aerobic degradation microorganism
Inhibiting effect, it is difficult to reach expected treatment effect.
Invention content
In order to overcome the deficiencies of the prior art, a kind of investment of present invention offer is small, takes up an area less, and effectively removing brewing spirit is highly concentrated
Ethyl alcohol, amylalcohol in degree waste water, butanol, CODcrAnd BOD5Brewing spirit high concentration wastewater treatment method.
In order to achieve the above object, wastewater treatment method of the invention is the high-concentration waste water collected by collecting-tank, by carrying
It rises pump to be promoted, be handled successively via stripper, heat exchanger, biological fluidized bed, artificial swamp and filtration system, processing waste water is sent
It is recycled in Returning heat-exchanger；The stripper is connected with the steam pipe of boiler for domestic, the steam provided by boiler for domestic
It heats up to the processing waste water of stripper, is warming up to 70-80 DEG C, soaking time is 20-40 minutes；The organism fluidization
Bed is connected with the escape pipe of oxygen cylinder, and oxygen is provided for the biochemical reaction in biological fluidized bed by oxygen cylinder.
Using this processing method, it is gas-liquid equilibrium and mass transfer velocity that vaporizing extract process, basic principle are taken in processing method
Theory, according to Henry's law, for weak solution, in certain temperature, when reaching balance between gas-liquid, dissolved gas is in the gas phase
Partial pressure is directly proportional to the concentration of molten gas in the liquid phase.Steam enters in stripping cavity, and water is warming up to 80 DEG C of (ethyl alcohol boiling points
78.4 DEG C, density 0.789kg/L) be connected into steam during play stirring action, be allowed to mutually come into full contact with, be dissolved in water
Gas and volatile materials pass through gas-liquid interface, are shifted to gas face, to achieve the purpose that remove polluter.Water vapour is led to
Enter in waste water, with the vapour pressure of aqueous solution (be equal to the vapour pressure of volatile materials with water vapor pressure and) just above extraneous pressure
Waste water begins to boil when power, thus accelerates the process that volatile materials is transferred to gas phase by liquid phase, on the other hand, when water steams
When gas passes through water layer with bubble regime, free interface is formd between water and bubble surface, this is liquid just constantly into bubble
Evaporation and diffusion begins to rupture when bubble rises on liquid level, the substance that can wherein volatilize to release.Using the physics
Method is first, greatly reduce COD, BOD concentration；Second, solve toxicity, it is better to back segment Aerobic Process for Treatment；It is right simultaneously
The steam thermal energy that boiler for domestic generates effectively saves the consumption of coal.
Treated sewage enters boiler for domestic system after artificial wetland treatment as normal-temperature water.Make effluent cycle
It utilizes.
Description of the drawings
Attached drawing is the process flow chart of brewing spirit high concentration wastewater treatment method of the present invention.
As shown in the figure：1, collecting-tank, 2, pump, 3, stripper, 4, heat exchanger, 5, biological fluidized bed, 6, artificial swamp, 7,
Filtration system, 8, oxygen cylinder, 9, boiler for domestic.
Specific implementation mode
The carrying out practically of the present invention is that high-concentration waste water enters collecting-tank 1 by conveyance conduit, by elevator pump 2, is entered
Stripper 3 after water level enters certain position, opens boiler for domestic 9, opens air-supplying valve, closes the high-temperature inlet water of heat exchanger 4
Valve is warming up to 80 DEG C or so by steam, reaches 80 DEG C of the boiling point of ethyl alcohol, keeps the temperature 30 minutes or so, opens institute thereafter
Some heat exchanger valves.So that 80 after heating DEG C of water is down to 30 DEG C, into biological fluidized bed 5, while opening 8 valves of Yang Qi bottle
Door, the purpose is to remove tannin, alcohols, aldehyde material in water removal.The water outlet of biological fluidized bed enters artificial swamp 6, then will be wet
Ground sewage flows through filtration system 7, is directly entered boiler for domestic water treatment system and reaches cycle purpose.
