Description
Technical field
The present invention relates to environmental technology field, specifically a kind of preparation method of the base of seaweed containing grease water-purifying material.
Background technique
China's seaweed biomass resource very abundant, seaweed yield rank first in the world.Seaweed biomass is compared to land
Biomass is advantageous.Seaweed growth in the sea, is being not take up land resource, and the speed of growth is fast, and growth course captures a large amount of titanium dioxides
Carbon, and absorb a large amount of nitrogen phosphorus of removal.Therefore, as can China coastal seas seaweed biomass is made full use of, there is important show
Sincere justice.
The main Land use systems of seaweed biomass include exploitation biomass energy and refinement algal product etc. at present.Seaweed institute
It not only can be used as important nutrient and healthcare products containing grease, and be alternatively arranged as the important oil plant source of biodiesel.All due to grease
It is wrapped in alginic cell, the extraction of seaweed grease at present is always the difficult point of seaweed biomass using energy source.According to estimation algae
Class produces in biodiesel process, and harvesting, drying and the grease extraction of algal biomass account for about production of biodiesel cost
50%, and high grease yield, dependent on harsh algae culture condition, 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, is reduced
Algae grease develops and uses cost, cuts down algae culture cost, has important practical significance.
By the retrieval discovery to existing technical literature, about algae grease use aspects, concentrate on how effectively extracting
In terms of seaweed grease.Up to the present, there is not yet not for the purpose of extracting algae grease, directly contain using the preparation of seaweed containing grease
The report of grease water-purifying material.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to which it is extra large containing grease to provide a kind of application seaweed biomass preparation
The method of algae base water-purifying material.
To achieve the above object, the invention adopts a technical scheme as:
A kind of preparation method of the base of seaweed containing grease water-purifying material,
1) by Lipid-producing seaweed according to 0.1-0.2g L-1Inoculum concentration be added in sea water medium, in 10-20 DEG C, light
Under the dark condition of culture than being 12h:12h, culture to Lipid-producing seaweed enters logarithmic growth phase latter stage, for use；
2) the poor Nutrient Stress sea water medium isometric with cultivating system is added in Xiang Shangshu Lipid-producing algae culture system,
Then then at 10-20 DEG C, under conditions of Light To Dark Ratio is 12h:12h, poor Nutrient Stress culture stimulation energy algae oil-producing is carried out, until algae
Quasi-grease content > 10%, for use；
3) 15mg L is pressed into the algae of fat content > 10% of above-mentioned acquisition-1Additive amount be added aluminium polychloride and
Nano ferriferrous oxide mixture (mass ratio 4:1), stirring coagulating sedimentation collects seaweed biomass, by the seaweed containing grease of collection
Steam blasting device is put into, steam blasting broken wall treatment is carried out；
4) seaweed containing grease after collecting above-mentioned broken wall is added into chitosan-cetomacrogol 1000 dilute acid solution, stirs
Mixing is mixed, solid is then collected, it is dry, the base of seaweed containing grease water-purifying material is made；Wherein, the seaweed containing grease after broken wall with it is dilute
The mass ratio between chitosan in aqueous acid is 1:30-60.
The Lipid-producing seaweed refers to the seaweed that can generate grease of growth and breeding in seawater；As green alga, diatom, chrysophyceae,
Chlorella and scenedesmus etc..
The sea water medium is that nitrogen content is greater than 40mg L-1, phosphorus content is greater than 3mg L-1Seawater.Such as sea-farming
Waste water, the seawater of rich Nitrogen-and Phosphorus-containing manually 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.
Sea-farming outlet tail water, coastal seawater such as.
The steam blasting broken wall treatment is the investment steam blasting device of seaweed containing grease that will be collected, and is passed through saturation and steams
Vapour rapidly releases stress in 105-150 DEG C of maintenance 5-15min and carries out broken wall to seaweed.
Chitosan concentration is 1-10wt% in chitosan-cetomacrogol 1000 dilute acid solution in the step 4), and shell is poly-
The mass ratio of sugar and cetomacrogol 1000 is 4:1；Wherein, diluted acid is the hydrochloric acid or acetic acid that concentration is 1-2%；The de- second of chitosan
Acyl degree > 50%.
A kind of application of the base water-purifying material of seaweed containing grease prepared, the adsorbing material of seaweed containing grease are being gone
For the application in purification of water quality in removal organic polluter and heavy metal multiple pollutant.
Principle: the present invention, which passes through, harvests grease-contained seaweed life using the cultivation in sea water Lipid-producing energy alga of rich Nitrogen-and Phosphorus-containing
After substance, cell wall damage processing is carried out so that lipophilic contaminants are molten to the suction of algae oil fat granule by subsequent steam blasting
Enrichment, while preventing grease grain from overflowing in algal biomass surface package chitosan film, finally prepare the base of seaweed containing grease
Water-purifying material is used 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 invention is to have abolished previous algae Lipid use to extract the available limitation in rear, effectively
The multiple technologies problem for overcoming seaweed grease higher value application to be faced, initial investment capital cost is cheap, being capable of rapid build
Reactor, enables seaweed biomass higher value application.
2) stablized using the base water-purifying material property of seaweed containing grease obtained by the method for the present invention, remove a variety of organic-inorganics in water removal
Pollutant is had excellent performance, and belongs to multiduty environment friendly material.
3) present invention preparation can be directly reaction mass using the fresh sample of seaweed, eliminate previous seaweed biomass reaction treatment
The step of preceding needs preparatory drying and dewatering, while steam blasting broken wall temperature of reaction system is lower than 150 DEG C, and it is quick-fried to belong to Low Temperature Steam
Broken reaction, the reaction time is less than 15 minutes, to greatly reduce energy consumption, while ensure that the preparation base of seaweed containing grease water purification material
The operability and safety of material.
