The method of rate.
Background technology
Vinasse are the byproducts of wine-making industry, are the direct leftover bits and pieces during wine brewing, it is rich in substantial amounts of nutriment such as
Crude starch, crude fibre, crude protein, nitrogen-free extracts, crude fat, amino acid and various vitamins, trace element, enzyme etc. are biological
Active material.And distillery waste water is a kind of high concentration, high-temperature, the organic wastewater of high suspended matter, remnants are mainly contained in waste water
The materials such as starch, crude protein, cellulose, various inorganic salts and mycoprotein.
According to statistics, annual output spirit stillage in China's reaches tens million of tons, and amount is big and concentrates, will if be pocessed not in time
It is putrid and deteriorated, the resource of preciousness is not only wasted, can also seriously pollute surrounding environment.Therefore, the comprehensive utilization of vinasse is to China
Development of resources and environmental protection tool be of great significance.
China has been achieved for certain achievement in the research of vinasse at present, for example, producing glycerine, culture food using vinasse
With bacterium, compound amino acid and trace element are extracted, extracts phytic acid and phytic acid calcium, makes vinegar, extracts protein, produces amylase and fibre
The plain enzyme of dimension, recycles biogas using vinasse anaerobic fermentation, produces SCP feeds, produce craboraffin, and dyeing is done also with lime fermentation
Former agent, for former wine reproduction, is applied to treatment of arthritis outside.Recently have been reported that using vinasse as raw material and produce ammonia with Lactobacillus brevis
Base butyric acid, liquid vinasse can also be used to cultivate Dipel, produce biogas, recovery waste heat.Carried using liquor-making byproduct yellow water
High vinosity etc., but among these in addition to as feed, the final whereabouts that other methods all cannot fundamentally solve vinasse is asked
Inscribe, and be possible to produce more poor slags, in addition vinasse complicated component, water content is high, is not easy storage and is not easy to utilize again
The fermentation filler such as rice husk, so the utilization of vinasse still suffers from certain difficulty.
Distiller's grain of alcohol waste water is high concentrated organic wastewater, can be to receiving water body environment if directly discharged without processing
Cause serious pollution.At present, most Alcohol Production enterprises all carry out distiller's grain of alcohol waste water at anaerobic-aerobic biology
Reason, but simply simple biodegradable processing, in addition to recovery section methane gas, seldom carry out returning for other mesostates
Receive and utilize, although so eliminating the influence of external displacement hull environment, cause the waste for no reason of a large amount of high-quality resources.
The content of the invention
