Description
Technical field
The present invention relates to environmental technology field, specifically a kind of preparation method of the base of marine alga containing grease water-purifying material.
Background technology
China's seaweed biomass resource very abundant, marine alga yield ranks first in the world.Seaweed biomass is compared to land
Biomass are advantageous.Seaweed growth in the sea, is being not take up land resource, fast growth, a large amount of titanium dioxides of growth course capture
Carbon, and absorb a large amount of nitrogen phosphorus of removal.Therefore, if China coastal seas seaweed biomass is made full use of, show with important
Sincere justice.
The main Land use systems of current seaweed biomass are including exploitation biomass energy and refine algal product etc..Marine alga institute
Not only as important nutrient and healthcare products, and the important oil plant source of biodiesel can be alternatively arranged as containing grease.Due to grease all
It is wrapped in alginic cell, the extraction of current marine alga grease is always the difficult point of seaweed biomass using energy source.According to estimation algae
In class production biodiesel process, harvesting, drying and the grease extraction of algal biomass account for production of biodiesel cost
50%, and grease yield high depends on the algae culture condition of harshness, and these seriously limit algae Lipid use industry
Development.Therefore, algae Lipid use new technology is created, this kind of grease-contained seaweed biomass is directly used, reduced
Algae grease develops cost, cuts down algae culture cost, has important practical significance.
Found by the retrieval to prior art literature, in terms of algae Lipid use, concentrate on and how effectively to extract
Marine alga grease aspect.Up to the present, there is not yet not for the purpose of extracting algae grease, directly application marine alga containing grease prepares and contains
The report of grease water-purifying material.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, there is provided one kind application seaweed biomass is prepared containing grease sea
The method of algae base water-purifying material.
To achieve the above object, the present invention use technical scheme for：
A kind of preparation method of the base of marine alga containing grease water-purifying material,
1) by Lipid-producing marine alga according to 0.1-0.2g L-1Inoculum concentration be added in sea water medium, in 10-20 DEG C, light
Dark ratio is 12h:Under the condition of culture of 12h, culture to Lipid-producing marine alga enters exponential phase latter stage, stand-by；
2) added and the isometric poor Nutrient Stress sea water medium of cultivating system to above-mentioned Lipid-producing algae culture system,
Then then at 10-20 DEG C, Light To Dark Ratio is 12h:Under conditions of 12h, carrying out poor Nutrient Stress culture stimulates energy algae oil-producing, to algae
Quasi-grease content>10%, it is stand-by；
3) to the fat content of above-mentioned acquisition>15mg L are pressed in 10% algae-1Addition add aluminium polychloride and
Nano ferriferrous oxide mixture (mass ratio 4:1), stirring coagulating sedimentation collects seaweed biomass, the marine alga containing grease that will be collected
Input steam blasting device, carries out steam blasting broken wall treatment；
4) collect the marine alga containing grease after above-mentioned broken wall to add into shitosan-cetomacrogol 1000 dilute acid solution, stir
Mixing is mixed, solid is then collected, dried, the base water-purifying material of marine alga containing grease is obtained；Wherein, the marine alga containing grease after broken wall with it is dilute
The mass ratio between shitosan in aqueous acid is 1:30-60.
The Lipid-producing marine alga refers to the marine alga that can produce grease of growth and breeding in seawater；As green alga, diatom, chrysophyceae,
Chlorella and grid algae etc..
The sea water medium is that nitrogen content is more than 40mg L-1, phosphorus content is more than 3mg L-1Seawater.Such as sea-farming
Waste water, artificial seawater of rich Nitrogen-and Phosphorus-containing prepared etc.；
The poor Nutrient Stress sea water medium is that nitrogen content is less than 20mg L-1, phosphorus content is less than 1mg L-1Seawater.
The outer last person's water of sea-farming such as, coastal seawater.
The steam blasting broken wall treatment is that the marine alga containing grease that will be collected puts into steam blasting device, and is passed through saturation steaming
Vapour, 5-15min is maintained in 105-150 DEG C, and rapidly discharge pressure carries out broken wall to marine alga.
The step 4) in shitosan-cetomacrogol 1000 dilute acid solution chitosan concentration be 1-10wt%, shell gathers
Sugar is 4 with the mass ratio of cetomacrogol 1000:1；Wherein, diluted acid is that concentration is the hydrochloric acid or acetic acid of 1-2%；The de- second of shitosan
Acyl degree>50%.
A kind of application of the base water-purifying material of marine alga containing grease for preparing, the adsorbing material of marine alga containing grease is going
The application being used in purification of water quality in removal organic polluter and heavy metal multiple pollutant.
Principle：The present invention harvests grease-contained marine alga and gives birth to by using the cultivation in sea water Lipid-producing energy alga of rich Nitrogen-and Phosphorus-containing
After material, by follow-up steam blasting carry out cell wall damage process be beneficial to lipophilic contaminants to algae oil fat granule inhale it is molten
Enrichment, while preventing grease grain from overflowing in algal biomass surface parcel chitosan film, finally prepares the base of marine alga containing grease
Water-purifying material, uses it for purification of water quality, removes the multiple pollutants such as removal organic polluter and heavy metal.
Advantage for present invention：
1) method of the present invention is to have abolished conventional algae Lipid use to extract the available limitation in rear, effectively
The multiple technologies problem for overcoming marine alga grease higher value application to be faced, initial investment capital cost is cheap, being capable of rapid build
Reactor so that seaweed biomass being capable of higher value application.
2) it is stable in properties using the inventive method gained base water-purifying material of marine alga containing grease, remove various organic-inorganics in water removal
Pollutant excellent performance, belongs to multiduty environment friendly material.
3) it can be directly reaction mass using the fresh sample of marine alga that prepared by the present invention, eliminate conventional seaweed biomass reaction treatment
The step of preceding needs advance drying and dewatering, while steam blasting broken wall temperature of reaction system is less than 150 DEG C, belong to Low Temperature Steam quick-fried
Broken reaction, the reaction time is less than 15 minutes, so as to greatly reduce energy consumption, while ensure that the preparation base water purification material of marine alga containing grease
The operability and security of material.
