Description
Technical field
The invention belongs to animal husbandry waste field of environmental improvement, and in particular to utilize fermentation brewage process, poultry waste is
For raw material, the method for preparing ethyl alcohol.
Background technique
The pollution of feces of livestock and poultry is not only the serious problems that animal husbandry developed countries and regions face, and is also animal husbandry
The environmental problem that developing country should pay close attention to.The animal husbandry developed country such as Holland, U.S. environmental pollution causes serious dirt
The typical event of dye, has become warning taken from the overturned card ahead.
Livestock and poultry feces waste has become huge concentrated contaminated water object source, gives an offensive smell, and makes soil by sewage, rainwater dilution
Earth pollution aggravation, soil environment are deeply impacted, and microorganism mainly has Escherichia coli, staphylococcus, bacillus and ferment in excrement
Female bacterium etc.；The pathogenic microbes contained include Penicillium notatum, Aspergillus flavus, black-koji mould and virus etc.；Helminth in excrement
Contain roundworm, coccidia, blood fluke, hookworm etc..
Existing manure of livestock and poultry pollution discharge treatment method is concentrated by modes such as manual, mechanical, water punchings mostly, the poultry of outdoor heap
The stench that waste spontaneous fermentation generates causes extreme influence to ambient enviroment, and the rainy day is especially serious, and maggot fly brings resident living
Inconvenience；Anaerobic fermentation is mostly used to prepare biogas on manure of livestock and poultry pollution discharge treatment method greatly, residue is as fertilizer, biogas operation
Effect, success or failure influenced by temperature, the constraint in season by gas transport, using above there is larger difficulty, although fermentation
Residue is recycling as fertilizer, and the gas for generation of fermenting really uses few, is thrown into atmosphere, the first in biogas
Alkane, hydrogen sulfide gas still pollute environmental gas；Poultry waste is fermented using the method for aerobic fermentation and post-processes system
It is standby to be recycled at organic fertilizer, due to fermenting not exclusively, usually occur " burning root " phenomenon in agricultural production application.It is original
Using aerobic or anaerobism mode, can all there be the gas discharge polluted to atmosphere.It is necessary to find a kind of to make manure of livestock and poultry
Dirty sufficiently fermentation, generates the available effective use of product, and residue reaches the method for organic fertilizer application effect, reduces poultry
Waste environmental pollution rationally recycles, is the major issue of animal husbandry sound development and environmental improvement.
Summary of the invention
The present invention provides the methods that alcohol is produced in fowl and livestock dirt fermentation, solve manure of livestock and poultry in currently available technology
Dirt cannot sufficiently ferment, and generate product and be unable to get effective use, the serious technical problem of poultry waste environmental pollution.
In order to achieve the above object, the present invention provides the following technical scheme that
The method of alcohol is produced in a kind of livestock and poultry feces fermentation, includes the following steps: fermentation, separation solid and liquids, refined liquid
Body object；
First in poultry waste bacterium and helminth inactivate, poultry waste is put into closed container heating and rises to 80-90
DEG C, 90-110min is kept the temperature, sterilizing terminates；
Contained solid weight in the sterilizing livestock and poultry feces of measurement, solid weight contained by the sterilizing poultry waste by measurement calculate, and use
HCL solution carries out acidification dilution processing, then proceedes to the object with HCL solution adjustment pH value between 2.0-3.0, after being diluted
Material；
When carrying out being cooled to 25 DEG C of room temperature to the material after dilution, solid weight contained by the sterilizing poultry waste by measurement, which is added, to be made
Wine auxiliary agent is fitted into round after mixing evenly, heat-preservation fermentation when being warming up to 40-60 DEG C；
Ca (OH) 2 is added after fermentation ends into system, isolates the first solid organic fertilizer and mash；
Mash is evaporated under reduced pressure out containing ethanol, and remaining liq is bottom liquid.
Further, the wine brewing auxiliary agent include: saccharomyces cerevisiae, carbohydrase, acid protease, potassium dihydrogen phosphate and
Cellulase.
Further, the parts by weight of the wine brewing auxiliary agent are as follows: 10-20 parts of saccharomyces cerevisiae, 10-15 parts of carbohydrase, acidity
5-20 parts of protease, 20-30 parts of potassium dihydrogen phosphate and 5-15 parts of cellulase.
Further, the mass concentration of the HCL solution is 55-70%.
Further, the processing method of the bottom liquid are as follows: bottom liquid is directly concentrated and dried to obtain the second solid, second is consolidated
Body, which is added in the first solid, is made organic fertilizer ingredient；Condensed water recycles or discharge.
Further, the temperature of the heat-preservation fermentation is 50-55 DEG C.
Further, the livestock and poultry feces solid-to-liquid ratio is water 1 by weight: solids 4-6.
Compared with prior art, the advantages and beneficial effects of the present invention are:
The method that ethyl alcohol is produced in livestock and poultry feces fermentation provided by the invention, can make micro- life of causing a disease in livestock and poultry feces
Object, sex pheromone and helminth obtain effective inactivation treatment.
The method that ethyl alcohol is produced in livestock and poultry feces fermentation provided by the invention solves existing skill without noxious gas emission
Original anaerobic fermentation prepares biogas in art, and ammonia, hydrogen sulfide, methyl mercaptan, Trimethylamine of generation etc. are with tart flavour, smelly
The irritative gas such as egg taste, fishlike smell, the technical issues of to air born pollution, the gas of generation is CO2.
The water nonpollution of the method discharge of ethyl alcohol, the liquid of discharge are produced in livestock and poultry feces fermentation provided by the invention
To distill condensed water, eutrophication will not be caused to water body.
The method product that ethyl alcohol is produced in livestock and poultry feces fermentation provided by the invention is ethyl alcohol, convenient for storage and fortune
It is defeated, and the curing organic fertilizer through sufficiently fermenting, " burning root " phenomenon will not occur again, realize refuse reclamation, prevent toxic
Gas discharge, achievees the purpose that poultry waste environmental pollution improvement.
The present invention to ingredients such as starch, protein, celluloses in poultry waste by be fully hydrolyzed preparing alcohol
Ethyl alcohol, ethyl alcohol mass concentration is high in mash obtained, and remaining solid object is processed and is applied to for curing organic fertilizer
Agricultural planting and aquaculture promote crop, realize refuse reclamation.
