Abstract
The invention discloses a method for recovering protein from wastewater of shrimp processing enterprises. The protein in the wastewater of the shrimp processing enterprises is separated and enriched by a floatation complexation extraction method, and a production process method for recovering the protein from the shrimp wastewater is provided. The effect of recovering the protein is obvious, the whole process is clean and environment-friendly, and the method is suitable to be promoted in the shrimp processing enterprises. The method has the advantages of simplicity, convenience, environment friendliness, and no secondary pollution.
Description
Technical field
The invention belongs to and a kind ofly from shrimp processing enterprise waste water, reclaim method of protein.
Background technology
In recent years along with shrimp aquaculture fast development already, the quantity and the scale of shrimp processing enterprise go from strength to strength, the mode of present stage a lot of enterprises shrimp processing is processed as the master with ripe shrimp, supervene a large amount of waste water, contain rich in protein in the waste water, fat, nutrition such as mineral substance and VITAMIN, has very high utility value, but materials such as water miscible protein a large amount of in the present waste water are without any recycling, directly be discharged in the wastewater disposal basin, not only increase the weight of the pressure of environmental protection treatment, and produce huge waste, the recycling economy industry policy of advocating with country is Bo mutually, therefore to recovery of protein utilization in these waste water, be the problem that modern aquatic food processing enterprise must pay attention to.
The method of protein recovery mainly contains ultrafiltration process and ion exchange method etc. in the trade effluent at present.Ultrafiltration process is to utilize the filtration membrane in different apertures, makes waste water flow through film through pressurization, thus the technology that macromole and small molecules are separated.But in ultra-filtration process, along with the prolongation of time, the film surface can deposit a lot of dirts, causes flow to reduce, and ultrafiltration apparatus investment itself is higher in addition, has limited its application and popularization.Ion exchange method also is in one of industrial separating and purifying protein matter and the most widely used method of amino acid, but the weak point of this method need to be batch operation, and efficient is low, the cost height.
The solvent floatation isolation technique is one of ordinary method of the separating beavy metal in the mining processing industry.Its cardinal principle is to have the surface that surface-active component to be separated is adsorbed on the micro-bubble that forms in the water, is brought into the top of flotation column along with the rising of bubble, is dissolved in the organic solvent and reaches the purpose of separation and concentration.
Because protein poorly soluble in organic solvent, can't use traditional solvent floatation technology separates, therefore select for use dioctylphosphoric acid ester to form the reversible complex compound, complex compound is stripped, the final purpose that realizes protein is carried out separation and concentration as complexing agent and protein.
Find not have proteinic report in the method separation and concentration waste water of shrimp of using the flotation complexing at present temporarily by retrieval.
Summary of the invention
The object of the present invention is to provide and a kind ofly from shrimp processing enterprise waste water, reclaim method of protein, use that the flotation complexing abstraction separates and enrichment the protein in the shrimp processing enterprise waste water, provide and from waste water of shrimp, recycled method of protein, it is remarkable to reclaim the protein effect, whole process clean environment firendly is applicable in the shrimp processing enterprise and promotes.
For achieving the above object, the technical scheme that the present invention takes is: use the flotation complex-extracting method, the surface that promptly has the micro-bubble that surface-active protein adsorption forms in water, be brought into the top of flotation column along with the rising of bubble, by the protein-complexing agents dioctylphosphoric acid ester complexing at top, collect complex compound, strip through hydrochloric acid soln, protein enters the aqueous solution once more, be rotated evaporation, obtain the white powder product after the drying, be the protein that separation obtains from waste water of shrimp.And complexing agent is reusable edible after regenerating.
Advantage of the present invention is simple, convenient and environmental protection, non-secondary pollution.
Embodiment
Embodiment 1
Waste water of shrimp is joined volume to be about in 1 liter, transparent floatation device, to highly about 3/4 place, upper surface at waste water adds 5～10 milliliters of complexing agent dioctylphosphoric acid esters again, by pipeline from floatation device bottom input air continuously, produce the micro-bubble that constantly rises, because protein has surfactivity by bubble absorption, after bubble breaks, the protein of liquid-vapo(u)r interface absorption come off and with dioctylphosphoric acid ester generation complex reaction, behind the blowing air 15～30 minutes, as seen water layer is as clear as crystal in the floatation device, and the upper strata organic layer presents milky white suspension.
Water sample after the flotation of learning from else's experience is handled and do not pass through respectively 100 milliliters of the waste water of shrimp of any processing, after sulfuric acid digestion, measure Protein content with azotometer, the result show waste water of shrimp through the flotation complexing handle the back protein content only be the untreated effluent sample protein content 5%, so the effect of dioctylphosphoric acid ester conjugated protein matter is very remarkable.
Simultaneously the milky white suspension of collecting after the flotation is placed separating funnel, strip with the HCl aqueous solution 1: 1 by volume～2 of pH＜1, the organism after the reextraction is the regenerated dioctylphosphoric acid ester, can put into Recycling in the floatation device.And the aqueous solution after will stripping, be rotated evaporation, obtain the white powder product after the drying, be the protein that separation obtains from waste water of shrimp.
The invention provides the producing and manufacturing technique that protein recovery is utilized in the waste water of shrimp, separation and concentration protein effect is remarkable, and therefore whole process clean environment firendly is applicable in the shrimp processing enterprise and promotes.
Claims (2)
1. one kind is reclaimed method of protein from shrimp processing enterprise waste water, it is characterized in that using the flotation complex-extracting method, the surface that promptly has the micro-bubble that surface-active protein adsorption forms in water, be brought into the top of flotation column along with the rising of bubble, the complexing agent dioctylphosphoric acid ester at top and protein form the reversible complex compound, collect complex compound, have reversible characteristics according to complex compound, hydrochloric acid soln with pH＜1 is stripped, protein enters the aqueous solution once more, the aqueous solution is rotated evaporation, obtains the white powder product after the drying, be the protein that separation obtains from waste water of shrimp.
2. according to claim 1ly a kind ofly from shrimp processing enterprise waste water, reclaim method of protein, it is characterized in that complexing agent reusable edible after regenerating.
