Abstract
The invention discloses a method for recycling protein from protein-contained waste water, which is characterized in that: the protein-contained waste water is firstly and primarily purified and decontaminated, after adding acid and/or alkali to adjust the pH value, natural flocculant algin is added into the waste water to be mixed and held, then the waste water is centrifugally or naturally precipitated and separated to obtain the protein sediment, and finally the protein sediment is dried to obtain the recycled natural and safe protein with strong solubility. By adopting inexpensive and edible raw material algin as the flocculant to process the protein-contained waste water, not only the protein-contained water is adequately purified, but also the recycled protein is free from having any component which is harmful to the human body, and can be widely applicable to the fields such as food, feed and the like. The method also can obtain favorable economic benefit and environmental benefit.
Description
Technical field:
The present invention relates to a kind of albumen recovery method, particularly a kind ofly from contain proteinic wastewater, reclaim proteic method.
Background technology:
In the course of processing of animal/vegetable proteins such as fishery products, meat product, bean product, can produce a large amount of proteinic wastewaters that contains, this type of waste water has organic content height such as albumen, characteristics that chemical oxygen demand is high, if effectively do not handle, serious environment pollution not only, and can waste a large amount of quality protein resources.Adopt suitable method that albumen in the waste water is recycled, not only can avoid the environmental pollution of waste water, and a large amount of protein resource of can regenerating.
Because it is lower to contain the general concentration of proteinic wastewater, if directly carry out concentrate drying, energy consumption is big, and is very uneconomical.Though membrane separation process can reclaim albumen in the waste water, because separatory membrane easily stops up, is difficult to manipulation of regeneration, cost is very high, is difficult to realize the mass-producing application.When the iso-electric point settling process was used separately, effect of settling was undesirable.Flocculence not only can efficient recovery albumen, and simple and easy to do, be easy to mass-producing and use.At present existing multiple flocculation agent is applied to proteic sedimentation and recovery, flocculation agent can be divided into two classes according to the source, one class is the synthetic chemical agent, comprise inorganics and organic polymer materials such as sodium polyacrylate, polyacrylamide such as iron trichloride, Tai-Ace S 150, another kind of is the material of natural origin, comprises mineral material and biomaterials such as tannin, chitosan such as wilkinite, diatomite.Though chemical floc is good to proteic flocculating effect, because it has certain toxic side effect to animal body, so its recovery protein product is difficult to widespread use.Be applied to fields such as feed and food if consider the protein product that will reclaim, then the natural biologic material flocculation agent is best selection.CN 101575371 discloses a kind of method with tannin processing silkworm cocoon processing wastewater and recovery sericin, but because the distinctive astringent taste of tannin, the albumen of recovery is difficult to be widely used in feed and field of food.CN 101624230 discloses a kind of proteic method in the flocculation agent reclaim(ed) sulfuric acid chrondroitin factory effluents such as chitosan of utilizing, the albumen that reclaims can be used as fodder additives and uses, because costing an arm and a leg and often needing of chitosan share with other coagulant aidss, so the economic benefit of this method is not high.
Summary of the invention:
Method based on existing albumen recovery, the object of the invention provides the method that a kind of new processing contains proteinic wastewater, this method can obtain safe and harmless recovery albumen when albumen fully recycles in guaranteeing waste water, can be applicable to fields such as feed and food.
A kind of proteic method that reclaims from contain proteinic wastewater of the present invention is characterized in that: mainly may further comprise the steps:
(1) rough purification is removed and is contained floating in the proteinic wastewater, suspension and impurity such as throw out, pigment;
(2) regulate the pH that contains proteinic wastewater;
(3) add algin, fully stir standing demix;
(4) solid-liquid separation;
(5) drying precipitate.
The described rough purification of step (1) is will contain the floating matter skim in the proteinic wastewater earlier or topple over and remove, then the middle layer is contained proteinic wastewater successively by in stone filtering layer, charcoal filtering layer, sand filter and the gac filtering layer one or more layers, to remove by filter impurity such as suspended substance, pigment, last reject bottom sediment miscellaneous object.Also can will contain after the middle layer sucking-off of proteinic wastewater successively through in stone filtering layer, charcoal filtering layer, sand filter and the gac filtering layer one or more layers and purify by siphonage.
The described adjusting of step (2) contains the pH of proteinic wastewater, looks original the pH difference of waste water, adds an amount of acid or alkali and regulates pH to 3.0-5.5, preferably is adjusted to pH 3.5-5.0.Described acid can be mineral acid, example hydrochloric acid, sulfuric acid, phosphoric acid etc. also can be organic acids, as acetic acid, citric acid, lactic acid etc., can also be above-mentioned multiple mineral acid or organic acid mixing acid, be preferably in the organic acids such as acetic acid, citric acid or lactic acid one or more.Described alkali is the mineral alkali of using always, as sodium hydroxide, potassium hydroxide, ammoniacal liquor etc.
The described algin of step (3) is selected food grade materials for use, and the addition of algin can contain in the proteinic wastewater and to add the 0.1-5.0g algin for every liter, is preferably every liter and contains and add the 1.0-2.0g algin in the proteinic wastewater.Described addition means be with algin earlier with after the abundant heating for dissolving of clear water, pour into again in the waste water, stir then.Described time of repose can be 1-24h, is preferably 8-16h.
The described solid-liquid separation of step (4) can be conventional methods such as centrifugal, heating evaporation, also can adopt siphonage sucking-off supernatant liquor, but should not adopt filtration method.
It is methods such as spraying drying, normal pressure heat drying, vacuum and heating drying or vacuum-freeze-dry that the described drying precipitate of step (5) can adopt.
A kind of proteic method that reclaims from contain proteinic wastewater of the present invention can be applied to proteic recycling in aquatic products processing wastewater (as the rotten poaching wastewater of fish), fowl poultry processing waste water (cutting apart poaching wastewater as the fowl poultry), the bean product processing waste water food industrial wastewaters such as (as bean product compacting waste water).
Technology of the present invention is simple, is easy to realize the mass-producing application.The algin that adopts edible natural to use is that flocculation agent reclaims albumen in the waste water, and any poisonous and harmful element that can not induce one makes the albumen that is reclaimed can be widely used in fields such as feed, food.Used algin is a material cheap and easy to get, and addition is few, and the cost that albumen is reclaimed reduces greatly.Compare with purify the method contain proteinic wastewater with chemical agent, the inventive method has not only realized the purifying treatment of waste water, and reclaims and obtained protein resource, is the method for a kind of environmental benefit and economic benefit bumper harvests.
