Abstract
The invention relates a annuliform production technique for producing alcohol with potato materials by utilizing anaerobic digesting solution as the technology ingredient water. The invention comprises the steps of: crushing potato starchiness materials, adding digesting solution, alpha- amylase, stirring uniformly, heating, incubating, liquefying, cooling, adding diastase, cooling after saccharification, inoculating yeast, culturing at constant temperature, distilling to obtain the product of alcohol, cooling the distilled waste mash, anaerobic-fermenting to obtain biogas, separating the broth to obtain digest and active sludge, and recycling the digest into the next fermentation to form a ring cycle. The distilled waste mash only needs anaerobic fermentation, which reduces the occupied ground area greatly and fixed asset investment. anaerobic fermentation is low cost, recycle of the digest can realize zero release of fermentation wastewater, completely eliminate the environmental pollution caused by the high concentration wastewater released by the present production of alcohol, and save large amount of water.
Description
Technical field
The present invention relates to a kind of annular production technique of utilizing anaerobic digestion solution to produce, belong to fermentation alcohol industrial technology field as the ethanol with potato raw material of technology batching water.
Background technology
Starchy material fermentative production alcohol is one of main method of Alcohol Production.In traditional starchy material fermentation producing wine Seiko skill, size mixing by water through pulverizing, adding for starchy material, boiling liquefaction and slight saccharification, inoculate then the distillery yeast fermentation (as " alcohol industry handbook one book is introduced, volumes such as Zhang Kechang, light industry press).The average alcohol per ton of traditional zymotic production technique will discharge 12～15 tons of useless mash, mash COD
CrMore than 40000～50000mg/L, not only cause serious water resource pollution, also cause a large amount of wastings of resources.
Existing Alcohol Production method of wastewater treatment mainly contains: the concentrate drying method is produced DDGS and first anaerobically fermenting and is produced behind the biogas aeration aerobic treatment etc.The concentrate drying method is produced DDGS and is had problems such as investment is big, working cost height.This method processed waste water energy qualified discharge, but still need to drop into certain working cost, therefore, the concentrate drying method is produced DDGS and is had good social benefit, and does not have economic benefit.Elder generation's anaerobically fermenting produce subject matter one that the method for aeration aerobic treatment behind the biogas exists be take up an area of big, investment is high, the 2nd, later stage aeration aerobic treatment has only to drop into does not have output, the treatment cost of waste water per ton up to 20 yuan about, the 3rd, waste water treatment is difficult to thoroughly, the waste water COD of discharging
CrStill about 500mg/L.The technology that adopts the slops circular batching is also arranged, but owing to contain a large amount of organic acids in the useless mash of the distillation after the zymamsis, the pH value is between 3.0～3.5, cause Ye Huamei can not normally bring into play vigor (optimum pH of Ye Huamei is between 6.0～6.5) when preparing burden the back liquefying starchiness raw material, cause slops partly to circulate, and circulation is batch limited, and a large amount of high-concentration wastewater emission are still arranged, and this method does not adopt on commercial production scale.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of alcohol annular production technique, the useless wine with dregs of tart distillation is through behind the anaerobically fermenting, and organism such as organic acid are degraded to biogas, has guaranteed that the reuse batching of Digestive system can not exert an influence to operations such as liquefaction, saccharification, fermentations; The useless mash of distillation only needs one step of anaerobically fermenting to handle, and can significantly reduce floor space and investment in fixed assets; The running cost of anaerobically fermenting is low, and the Digestive system recycle can realize the zero release of fermentation waste water, can eliminate the high-concentration waste liquid environmental pollution caused by discharge in the present Alcohol Production fully, and can save a large amount of precious water resource.
Main solution of the present invention is achieved in that
The present invention is the following processing step of alcohol annular production employing of main raw material with the potato class:
1, gets the potato starch raw material and pulverize upward batch Digestive system of back adding, the ratio of potato starch and Digestive system is 1: 2～5, adopt tap water to supply when Digestive system is not enough, after mixing, add high temperature resistant α-Dian Fenmei, the α-Dian Fenmei addition is 6～15U/g starch, and post-heating stirs, Heating temperature: 90～105 ℃, insulation liquefaction 50～120 minutes; Fast cooling to 60～65 ℃;
2, add saccharifying enzyme, the saccharifying enzyme addition is 80～150U/g starch, is 60～65 ℃ of insulation saccharification 0.5～1.5hr down in temperature, and saccharification is cooled to 28～35 ℃ after finishing;
3, insert the distillery yeast that spreads cultivation (yeast-inoculated amount) of 8～10%V/V, constant temperature culture fermentation 40～72hr, the ethanol concn in the maturing fermentation liquid is 8.0～15%v/v, obtains finished product alcohol through distillation;
4, the useless mash of getting after the above-mentioned distillation of distillation is cooled to 40～70 ℃, sends into anaerobic fermentation tank, and the constant temperature anaerobically fermenting was produced biogas in 10～15 days; The biogas supply boiler that acts as a fuel; Anaerobic fermented liquid obtains Digestive system and active sludge through solid-liquid separation; Digestive system loops back the next batch fermentation, constitutes annular collar, an infinite loop successively.
Potato starch raw material of the present invention can adopt potato raw materials such as Ipomoea batatas, cassava.
The pH value of Digestive system of the present invention is 6.0～8.0.
Compared with the prior art the present invention has the following advantages:
The useless wine with dregs of tart distillation among the present invention is through behind the anaerobically fermenting, and the useless mash of distillation is produced biogas by anaerobically fermenting, COD in the waste water
CrDrop to about 2000mg/L, the pH value rises to 6.0～8.0, and organism such as organic acid are degraded to biogas, has guaranteed that the reuse batching of Digestive system can not exert an influence to operations such as liquefaction, saccharification, fermentations; 2, the useless mash of the distillation among the present invention only needs one step of anaerobically fermenting to handle, and has significantly reduced floor space and investment in fixed assets; 3, got rid of the high aeration aerobic treatment of running cost among the present invention, and the running cost of anaerobically fermenting is low, the useless mash of distillation of adding alcohol per ton can produce about 350m
3The active sludge (can process about 300 kilograms of compound bio matter fertilizers) of the biogas of (mark attitude) (amounting to 350 kilograms of commercial coals approximately) and 200 kilograms, therefore, this technology has good economic benefit; 4, anaerobically fermenting Digestive system recycle among the present invention realizes the zero release of fermentation waste water, does not have fermentable discharge of wastewater, can eliminate the high-concentration waste liquid environmental pollution caused by discharge in the present Alcohol Production fully, and can save a large amount of precious water resource.
