Abstract
The combined treatment for eliminating alcohol effluent pollution and utilizing molasses resource includes culturing geotrichum with alcohol effluent to reduce COD and BOD, self-dissolving extraction of 5'-nucleotide, seasoning powder and karyorhexis protein from geotrichum, and treating waste water after geotrichum extraction either with anaerobic and aerobic organisms to obtain methane fuel and water suitable for direct discharge or through evaporation concentration to obtain caramel and active organic fertilizer without waste water exhausted. The present invention realizes high environment utility and economic utility.
Description
The invention belongs to environmental pollution treatment technology, be specially adapted to the improvement of molasses alcohol waste liquid and the utilization of resource thereof.
At present, cane sugar factory is generally all produced alcohol with molasses, and the alcohol slops COD of fermentation back discharging is about 10-14 ten thousand mg/L, and BOD is about 4-6 ten thousand mg/L, and colourity is big, the acidity height.As direct discharging, can serious environment pollution.According to surveying and determination, contain the residual sugar of 1-2.5% in the waste liquid, the organic acid of 6-8%, pigment, the nitrogen of 2-4%, phosphorus, potassium and trace do not have plain, are a kind of available resources.In order to solve the pollution of alcohol slops, the method for current employing roughly has: (1) oxidation pond process.Promptly waste liquid is stored with big pond, overflow stage, discharging equaled to be untreated.(2) evaporation concentration method.Promptly waste liquid is evaporated by triple effect, quadruple effect, do composite fertilizer again behind concentrated solution system composite fertilizer or the system dry powder.This method energy consumption is big, and added value of product is low.(3) anaerobism producing methane.Simple anaerobic treatment of waste water can not qualified discharge.(4) anaerobism---aerobic series connection is handled.Though this method waste water can qualified discharge.But can only obtain single product---biogas, economic benefit is not high enough.(5) doing boiler flue uses towards buck.This method just becomes intermittently discharged to continuous blow-down.(6) EM technology.The volume of oxidation pond is big especially, and it is slowly up to standard to take 7-8 month ability.
More than these technology generally speaking, or not thorough, or promote because of deficiency in economic performance is difficult because of administering.
The objective of the invention is to provide a kind of combined treatment of molasses alcohol effluent resource method.It can not only make discharged wastewater met the national standard, and the useful matter in the waste liquid can be converted into the high Nucleotide of economic benefit, takes off nucleoprotein powder, delicate flavour powder and biogas or caramel colorant, active organic fertilizer, turns waste into wealth.
The objective of the invention is to realize in such a way:
With molasses alcohol waste liquid is that raw material is cultivated geotrichum candidum, cuts down COD30%.Through separate geotrichum candidum mycelium and geotrichum candidum waste water.The autolysis method self-dissolving of geotrichum candidum mycelium, from from solution, extract 5 '-Nucleotide.The crystalline mother solution concentrate drying gets the delicate flavour powder.Not molten mycelium residue drying must be taken off the nucleoprotein powder.Geotrichum candidum waste water through anaerobic-aerobic carry out a biological disposal upon clean fuel biogas, water quality reaching standard discharging; Or use evaporation concentration method, make caramel colorant and active organic fertilizer, wastewater zero discharge.
Advantage of the present invention is that biotechnology and green technology are combined, not only solved the pollution problem of molasses alcohol waste liquid to environment, and, obtain the high a plurality of products of economic benefit with alcohol effluent resource, realized the unification of environmental benefit, social benefit and economic benefit.
The present invention is described in further detail below in conjunction with embodiment:
Embodiment 1:
Alcohol slops cooling left standstill remove solid substance, pump in the fermentor tank, insert the geotrichum candidum bacterial classification of 5-10%, at 25-32 ℃, under the PH4-9 condition, fermented 6-10 hour, the fermented liquid press filtration is got the geotrichum candidum mycelium, after the washing it is joined in the borax soln of PH8.5-10, under 25-35 ℃ of condition self-dissolving 14-20 hour, leach the mycelium slag, dry, pulverize to such an extent that take off nucleoprotein powder, protein content＞40%.Transfer to PH1-2 from solution with HCL, elimination precipitation is used charcoal absorption, uses ammoniacal liquor-ethanolic soln wash-out again, and filtering drying gets 5 '-Nucleotide.The crystalline mother solution spraying drying gets the delicate flavour powder.Raffinate behind the fermentation geotrichum candidum, each wastewater dilution adds coagulating agent flocculation SO to COD value 4-5 ten thousand mg/L in the united extraction Nucleotide operation
4 2-, pump into Air-float separator, remove throw out, then enter anaerobic pond, under 35 ℃ of PH6-7 conditions, hydrolysis, acidifying and methanation, and use biogas recirculation, remove the hydrogen sulfide microbubble, enter gas-holder behind the absorption tower absorbing hydrogen sulphide of giving vent to anger, as fuel through ferrous sulfate is housed.The iron sulphide that the absorption tower reaction obtains separates behind the sedimentation and filtration and makes industrial chemicals, and the waste water of anaerobism after 48 hours is after the pre-exposure sedimentation, and it is aerobic to enter charcoal fluidized-bed Aerobic Pond.Fed pressurized air 3.5 hours, the precipitation that produces when aerobic, through the settling bowl sedimentation, 30% mud returns the biological fluidized bed Aerobic Pond, and 70% mud is sent into the mud bucket, makes fertilizer after the dehydration, the COD＜200mg/L of water quality.
Embodiment 2:
Adopt the identical method of embodiment 1, cultivate geotrichum candidum with alcohol slops and extract Nucleotide, the delicate flavour powder takes off the nucleoprotein powder.Isolating geotrichum candidum waste water, with NaoH fermented liquid is neutralized to PH6-7, pump in the multi-step evaporator, at pressure is 0.08MPa, temperature is to be concentrated to the 25-30Be degree one by one under the 80-90 ℃ of condition, and with concentrated solution freezing leaving standstill 24 hours under 0-4 ℃, upper strata liquid is made the caramel colorant raw material, extract caramel colorant, the thick shape precipitation of lower floor is made active organic fertilizer.
Claims (1)
1, a kind of combined treatment of molasses alcohol effluent resource method comprises two parts of raffinate aftertreatment after with microorganism alcohol slops being fermented once more and ferments:
(1) in molasses alcohol waste liquid ferments once more, the bacterial classification of selecting for use is a geotrichum candidum, gained geotrichum candidum mycelium, use the autolysis method self-dissolving, from from solution, extract 5 '-Nucleotide, the crystalline mother solution spraying drying gets the delicate flavour powder, not molten mycelium residue drying and crushing must be taken off the nucleoprotein powder.
(2) the geotrichum candidum raffinate after the fermentation, handle through coagulation, air supporting, anaerobism, pre-exposure, aerobe, discharge during water-quality COD＜200mg/L, anaerobic biological treatment produces biogas, or use evaporation concentration, concentrated solution is 0-4 ℃ in temperature and obtains through refining caramel colorant and active organic fertilizer, the water quality zero release after freezing the leaving standstill down.
