Abstract
The invention discloses a novel flocculant capable of recovering protein from wastewater generated in the food processing industry. It uses seaweed as raw material, and is made up by using seaweed as raw material, through the processes of cleaning, drying in the air, breaking, soaking in sodium carbonate solution with a certain concentration for a certain time, placing under the homogenizer, shearing into paste-like material at high speed of 10000 rpm, diluting, and can be used.
Description
The present invention relates generally to a kind of, from the waste liquid that food-processing industry produces, reclaims proteinic novel flocculant.
At present, be that the most processing industries and the fermentation industry of raw material all exists loss and the problem of environmental pollution that contains protein resource with beans, grain, potato class, fowl poultry and fishery products etc.In traditional wastewater processing technology, biological degradation method, costly, the cycle is long, and resource can not get recycling simultaneously, and flocculation sediment often relates to the toxicity of flocculation agent or pharmaceutical chemicals, and the protein of recovery can't be used.In recent years, though there are the achievement in research of nontoxic flocculation agent in the U.S., Japan, be still the too high simplification compound of a class tooling cost basically, as many chitoses etc., also need add more than one coagulant aids or polymer chemistry thing synergy simultaneously,, can not be extensive use of owing to cost an arm and a leg.
Task of the present invention is to provide a kind of nontoxic, is different from other novel flocculant, and it can reclaim protein resource from the waste liquid of food-processing industry, use the feed of animal as.
Task of the present invention is finished in such a way: with seaweed plant such as Eucheuma muricatum (Gmel.) Web, carrageen, wakame, sea-tangle, Radix Laminariae and seaweed industry thereof contain frond tankage etc., can be separately or mix arbitrarily as the raw material of making flocculation agent, at first raw material is cleaned and dried, through tentatively being broken into directly particle through being 0.5～2 centimeter, then this particle is placed on the carbon na concn and is in 0.3～0.4% the aqueous solution and soaked 20～40 hours, the weight ratio of the raw material and the aqueous solution is 2～4: 100, be placed under the homogenizer, under 10000 rev/mins high speed shear effect, make feed particles in the shortest time, smash into the mashed prod of high dispersing, adding fresh water is 1～2% concentration with the sticky dilution of this dispersed system, promptly become flocculation agent, be beige, can directly use.
In order to load and transport conveniently, can pH value be transferred to 4～5 to the dense HCl of the sticky adding of dispersed system, through precipitation, squeezing, 80 ℃ of oven dry down, get final product solid dry powder novel flocculant, be light brown, to turn to concentration during use and be 1～2% solution.
The present invention implements like this: containing the general temperature of proteinic factory effluent and be＞10 ℃, is optimum temps with＞20 ℃.The pH value that will contain protein waste water with dense HCl transfers to about 4, simultaneously with 100 times/minute, stirs 2 minutes, to guarantee the homogeneity of waste water.Ratio by pressed powder flocculation agent and the contained organic solid substance of waste water is 1～2: 100, by adding the flocculation agent dispersion liquid, stirred 3 minutes with 100 times/minute simultaneously, then stirred 2 minutes with 50 times/component velocity, order static more than 2 hours or reach sedimentation equilibrium stir completely reaction solution, the sedimentation material dewaters with technology such as press filtration, spraying, vacuum filtration, steam rotating cylinder or centrifugations, and the back oven dry is finished product-solid protein matter.
It is in extensive range that the present invention uses, and generally can be used for:
1, the starch take beans, potato class, corn as raw material, the waste water that the bean vermicelli processing industry produces;
2, the waste water that already produces of the gourmet powder fermenting take grain, starch as raw material;
3, be the terramycin of raw material with grain, potato class, the waste water that waits fermentation industry to produce of catarrh mycin;
4, with grain, potato class be the waste water of the drinks Brewing industry generation of raw material;
5, the waste water that already produces of organic acid fermentation such as citric acid;
6, the waste water of fishery products, poultry and egg, diary industry generation;
The protein that adopts the present invention to reclaim is generally useed concentrated feed as, has bigger economic benefit, is 100 yuan of every inputs (comprising cost, labor service equipment, expenses such as management) substantially, and output is a 200-600 unit, and economic benefit is obvious.
Claims (6)
1, a kind of seaweed plant is that the flocculation agent of raw material is characterized in that raw material is cleaned, and dries, fragmentation.
2, by the flocculation agent of claim 1 regulation, it is characterized in that with concentration of sodium carbonate be 0.3～0.4% solution soaking 20～40 hours, the weight ratio of raw material and solution is 2～4: 100
3,, it is characterized in that solution with raw material and immersion is placed on that the high speed shear with 10000 rev/mins becomes mashed prod under the homogenizer by the flocculation agents of claim 1 or 2 regulations.
4,, it is characterized in that mashed prod is diluted to 1～2% concentration for use by the flocculation agent of claim 3 regulation.
5,, it is characterized in that adding HCl and transfer PH=4～5, through precipitating, squeeze, be dried into the flocculation agent of the solid thing of powder dress thing by the flocculation agent of claim 4 regulation.
6, by the flocculation agent of claim 5 regulation, it is characterized in that when practicality, will adding aquation and become 1～2% concentration.
