Description
Technical field
The present invention relates to technical field of wastewater recovery, a kind of method recycled more particularly to soybean wastewater.
Background technique
Bean product are deep by a kind of favorite vegetable protein food of our people, and protein content is high, amino acid forms
Rationally and nutritive value height, taste and flavor are good.Based on bean curd, herein on derive dried bean curd, fermented bean curd, skin of beancurd etc.
Various bean products enrich the diet of people.However, a large amount of waste water can be generated in bean product production process, wherein being mainly
The yellow serofluid generated in waste water caused by bubble beans waste water, cleaning equipment used in bubble beans and expressing process.It is every to produce bean product
Bubble beans waste water, the yellow plasm of soybean of 4~5t and the cleaning waste water of 10t or so of 1t or so can be about generated using 1t soybean.
These wastewater biological oxygen demand (BOD), chemical oxygen consumption (COC) (COD) value are higher, and total nitrogen and ammonia nitrogen are also higher, and belonging to high concentration can give birth to
The property the changed high waste water of degree, especially yellow serofluid, COD are up to 10000~20000mg/L.With the increasing of bean product processing capacity
Greatly, it also urgently needs to solve the problem of wastewater treatment.Contain the biologies such as protein, oligosaccharide, isoflavones in soybean wastewater
Active material.
Soluble solid content (mg/g) in 1 soybean wastewater of table
The protein majority contained in soybean wastewater is soybean whey protein, and main component is 2S ingredient and β-starch
Enzyme, relative molecular mass are mainly distributed between 10000~30000, have good dissolubility and foaming characteristic.Wherein 2S ingredient
In trypsin inhibitor be traditionally considered as anti-nutritional factors, but the trypsin inhibitor of low concentration has centainly
Inhibit cancer to occur, reduce the effect of cholesterolemia.
Isoflavones is to be present in one of soybean bioactive ingredients, have pre- anti-cancer, adjust female hormone,
The different physiological roles such as anti-oxidant, pre- preventing bone rarefaction, physical property is not soluble easily in water, but has in the hot water certain
Dissolubility, so in the forming step of bean product with waste water flow out a part, account for about soybean total isoflavone content
50% or so.
Soyabean oligosaccharides are the general names of soluble oligosaccharide in soybean, and main component is raffinose, stachyose and sucrose.Its
Middle raffinose and stachyose, which can not be digested enzyme in human body and decompose, to be absorbed, but can be by the Bifidobacterium in human body intestinal canal
It utilizes, causes the proliferation of Bifidobacterium, and soyabean oligosaccharides are very small for the proliferation function of harmful bacteria.Bifidobacterium is in intestines
Soyabean oligosaccharides are resolved into lactic acid and acetic acid in road, reduce intestinal pH, inhibit harmful bacterial growth, to reach improvement enteron aisle
The purpose of environment.During making bean product, bean or pea, which wear into slurry and boil, makes most albumen using the process of solidification
Matter all forms solid, and the water solubility of soyabean oligosaccharides is very good, thus most soyabean oligosaccharides be all present in therewith it is useless
Among water.
Because there is the presence of above functions substance, if only soybean wastewater is entered at sewage disposal system
It is discharged after reason, not only wastes good resource, but also the difficulty and cost that sewage treatment will be greatly increased significantly.Integrated treatment
Soybean wastewater is to recycle effective component therein, and COD, the solubility of waste water can be significantly reduced after recycling
Solid content and other indexs do so not only effectively to be located in and have managed waste water, but also make the investment to return flow
There is return, is the thing killed two birds with one stone.
At present for the main method of soybean wastewater comprehensive utilization as disclosed in 103265614 A of patent CN: will give up
After water pretreatment, protein concentrated solution and ultrafiltration membrane permeate are obtained through ultrafiltration membrane；Soyabean protein powder, ultrafiltration membrane is made in concentrate egg white liquor
Permeate is after resin adsorption, and with ethanol elution resin, washing lotion is used for isoflavones processed；Resin efflux is obtained by nanofiltration membrane
To oligosaccharide concentrate and nanofiltration membrane permeate, oligosaccharide concentrate is for making oligomeric Icing Sugar, and nanofiltration membrane permeate is using anti-
Permeable membrane can obtain pure water.
Current technology is mainly the method recycling albumen for passing through UF membrane, different with resin adsorption or solvent method recycling soybean
Flavones.But since the solid content of soybean wastewater is very low, only 1% or so, using the above method handle equipment at
This is very big, and other organic matters such as grease are very big to the interference effect of film and resin, equipment cleaning, regeneration or the week replaced
Phase is short, and the efficiency of operation is very low.For disadvantage mentioned above, the present invention proposes what a kind of soybean wastewater high efficiente callback utilized
Method.
Summary of the invention
In view of the above shortcomings, the purpose of the present invention is to provide the systems that a kind of Guilin rice-flour noodle is burnt with non-fried crackling pot
Make method, does not use frying technological process, and the unique oral sensations for keeping crackling pot to burn of energy long period are with regard to flavor.
Technical solution of the present invention is summarized as follows:
A kind of method that soybean wastewater recycles, wherein the step of this method is as follows:
1) it pre-processes
Waste water filtering or filters pressing are removed into the solid contents such as bean dregs, impurity, obtain filtrate；
