Abstract
The invention provides a liquor brewage high-concentration waste water treatment method. According to the method, high-concentration waste water collected through a water collection tank is lifted through a lifting pump and then is treated through a stripping tower, a heat exchanger, a biological fluidized bed, a constructed wetland and a filtration system and the treated waste water is returned to the heat exchanger and is recycled. The stripping tower is connected to a steam pipe of a domestic boiler, steam provided through the domestic boiler heats the treated waste water in the stripping tower to a temperature of 70-80 DEG C and then is subjected to thermal insulation for 20-40min, the biological fluidized bed is connected to a gas outlet pipe of an oxygen bottle and the oxygen bottle provides oxygen for a biochemical reaction in the biological fluidized bed. The method has a small investment and a less land occupation area and effectively removes impurities such as ethanol, pentanol, butanol, CODcr and BOD5 in liquor brewage high-concentration waste water.
Description
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of brewing spirit high concentration wastewater treatment method.
Background technology
The traditional liquor mode of production is solid state fermentation, there is production efficiency low consumption grain big, and energy consumption is big, the dirt of generation
Dye thing is also big, has data to show, often produces one ton of ethanol, will produce the drunk fish of about 12 15 tons, wherein BOD5Value is
25g/t 30 g/t, CODcrValue is for 80g/t 120 g/t, and liquor production wastewater can be basically divided into high-concentration waste water, low dense
Degree waste water.Wherein, high-concentration waste water includes: distillation residual water, drunk fish, fermentation vat Leachate site, go with wine storehouse percolating water, steaming
Evaporating workshop section's flushing water etc., high-concentration waste water is mainly composed of yellow fluid, low-carbon alcohols (ethanol, amylalcohol, butanol etc.), fatty acid, amino
Acid etc..Due to the particularity of liquor industry, introduce according to " Fujian light textile " (phase June the 6th in 2007, total 21 phases), the most domestic also
A liquor-making enterprises is not had to have the waste water control scheme of maturation.The process technique that current domestic several esbablished corporations use is such as
Under:
These processing method first stage are that pretreatment includes filtration, gravitational settling, air supporting, neutralization, anaerobic degradation；Second stage
It is exactly that two stage treatment includes anaerobism, aerobic absorption etc..Using these conventional treatment processes, the big occupation of land of investment is many, fluctuation of service,
Middle-size and small-size wine brewing manufacturing enterprise pole is not suitable for.The notification number announced for this situation Chinese patent is CN102674615A
" a kind of Chinese liquor sewage treatment process ", its technique is: the sewage produced from brewing spirit sequentially passes through thickness grid, regulation
The folded wrong formula filtration of material of pond, hydrolysis acidification pool, sedimentation tank, up-flow anaerobic sludge blanket, sequencing batch active sludge and spiral this 7
Individual recipe step is discharged after processing, and has sludge reflux between described batch-type sludge and sedimentation tank the two processing step
This processing step, the water outlet of described sedimentation tank enters described up-flow anaerobic sludge blanket after pump promotes.This technique is also only
It it is the knot utilizing folded wrong three technological processes of formula filtration of material of up-flow anaerobic sludge blanket, sequencing batch active sludge and spiral
Close, also without for brewing spirit high-concentration waste water accounts for the ethanol of main component, amylalcohol, butanol etc., CODcrAnd BOD5High
Special circumstances emphasis to process the biochemical of technique good, ignore the process technique inhibitory action to aerobic degradation microorganism, difficult
To reach intended treatment effect.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention provides a kind of investment little, takes up an area few, effectively removes brewing spirit highly concentrated
Ethanol in degree waste water, amylalcohol, butanol, CODcrAnd BOD5 Brewing spirit high concentration wastewater treatment method.
In order to achieve the above object, the method for wastewater treatment of the present invention is, collecting-tank the high-concentration waste water collected, by carrying
Rise pump to promote, process via stripper, heat exchanger, biological fluidized bed, artificial swamp and filtration system, process waste water and send heat back to
Exchanger recycles；Described stripper is connected with the steam pipe of boiler for domestic, boiler for domestic the steam provided is to vapour
The process waste water of stripper heats up, and is warming up to 70 80 DEG C, and temperature retention time is 20 40 minutes；Described biological fluidized bed with
The escape pipe of oxygen cylinder is connected, oxygen cylinder provide oxygen for the biochemical reaction in biological fluidized bed.
Using this processing method, take vaporizing extract process in processing method, its ultimate principle is gas-liquid equilibrium and mass transfer velocity
Theory, according to Henry's law, for weak solution, in uniform temperature, when reaching balance between gas-liquid, dissolved gas is in the gas phase
Dividing potential drop is directly proportional to molten gas concentration in the liquid phase.Steam enters in stripping cavity, and water is warming up to 80 DEG C of (ethyl alcohol boiling point
78.4 DEG C, density 0.789kg/L) be connected into steam during play stirring action, be allowed to mutually be fully contacted, be that water dissolves
Gas and volatile material, through gas-liquid interface, shift to gas face, thus reach to remove the purpose of polluter.Water vapour is led to
Enter in waste water, with the vapour pressure of aqueous solution (equal to volatile material vapour pressure and water vapor pressure and) just above external world's pressure
During power, waste water begins to boiling, thus accelerates volatile material and is proceeded to the process of gas phase by liquid phase, on the other hand, when water steams
When gas passes water layer with bubble regime, defining free interface between water and bubble surface, this is that liquid is the most constantly in bubble
Evaporation and diffusion, when bubble rises on liquid level, begins to rupture, thus the material that release wherein can be volatilized.Use this physics
Method one, greatly reduces COD, BOD concentration；Its two, solve toxicity, better to back segment Aerobic Process for Treatment；The most right
The steam thermal energy that boiler for domestic produces effectively saves the consumption of coal.
Sewage after process, after artificial wetland treatment, enters boiler for domestic system as normal-temperature water.Make effluent cycle
Utilize.

Detailed description of the invention
The carrying out practically of the present invention is, high-concentration waste water enters collecting-tank 1 by conveyance conduit, by elevator pump 2, enters
Stripper 3, after water level enters certain position, opens boiler for domestic 9, opens air-supplying valve, close the high-temperature inlet water of heat exchanger 4
Valve, is warmed up to about 80 DEG C by steam so that it is reach the boiling point 80 DEG C of ethanol, is incubated about 30 minutes, opens institute thereafter
Some heat exchanger valves.The water making after intensification 80 DEG C is down to 30 DEG C, enters biological fluidized bed 5, opens oxygen 8 valve simultaneously
Door, its objective is the tannin in removal water, alcohols, aldehyde material.The water outlet of biological fluidized bed enters artificial swamp 6, then by wet
Ground sewage flows through filtration system 7, is directly entered boiler for domestic water treatment system and reaches to circulate purpose.
