Abstract
The present invention relates to a method for preparing an inhibitor of skeletonema costatum, which belongs to the field of water treatment. The preparation method of ulva linza extracting solutions used for inhibiting skeletonema costatum comprises the following steps: leaching ulva linza by sterilized seawater, ethyl alcohol, propanone, ethyl ether or chloroform; concentrating the obtained extracting solution with a rotary evaporation method; putting the concentrated extracting solution into a water body to be treated for inhibiting the growth of red tide algae in the water body to be treated. In general, per kilogram ulva linza is leached for 0.5 to 2 days by 30 to 50 liters of seawater; the obtained extracting solution is concentrated to obtain a concentrated solution whose volume is 10% of the original volume, and then the concentrated solution is put into the water body to be treated; 2 to 10 milliliters of the concentrated solution is put into per liter water body to be treated. The present invention makes full use of the ulva linza in ulva linza plants, has the advantages of high efficiency, safety and easy operation and control, effectively inhibits the growth of harmful red tide algae in oceans, especially the growth of skeletonema costatum, and is widely used the in the water bodies of coast areas, ports, bathing beaches, aquaculture bases, etc. for controlling red tides.
Description
Technical field
The invention belongs to water treatment field, relate in particular to a kind of preparation method of inhibitor of middle Skeletonemacostatum.
Background technology
After Lu Yuan nutritive substance and ocean operation discharging and the pollutent that leaks enter ocean water body, causing the seawater eutrophication, is the major cause that ocean environment worsens.Eutrophication causes the explosive growth of red tide algae, can reduce the dissolved oxygen of seawater, brings massive losses for the aquatic products aquaculture.Some algae can also produce the algae toxin, and feed water lively thing and human beings'health are brought harm.Middle Skeletonemacostatum is the coastal common and main red tide algae in Eastern China, therefore usually with the representative of middle Skeletonemacostatum as the red tide algae.
Existing alexandrium tamarense inhibitor is mainly the organic herbicide of cupric ion preparation and synthetic.Utilize cupric ion (Cu now
2+) to kill the red tide algae be to use the most sophisticated a kind of red tide inhibition technology, but cupric ion in water body, can not degrade, can in the ecosystem, transmit by food chain, and copper ion concentration high more (the biological amplification) in the high more organism of trophic level.If the people has eaten the enrichment hydrocoles of cupric ion, meeting serious harm HUMAN HEALTH.The artificial weeding agent can be killed other plant in the Marine ecosystems when killing the red tide algae, make water ecosystem destroyed, and ecological functions disappear, and finally makes the ocean become " Dead Sea " that biomass sharply descends.Therefore, need that exploitation is efficient badly, the red tide inhibitor of safety, easy operation control.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of inhibitor of middle Skeletonemacostatum is to remedy the deficiencies in the prior art.
The present invention is by lot of experiments, and filtering out from multiple kelp has remarkable inhibiting feldspar water shield to the red tide algae, and then has the extracting solution of algal control function to drop into inhibition red tide algae growth in the seawater it.Therefore the extracting solution of feldspar water shield can be used as the application that suppresses the red tide algal grown.
The preparation method of the feldspar water shield extracting solution of Skeletonemacostatum is in the inhibition: with solvent is sterilization seawater lixiviate feldspar water shield, then the extracting solution that obtains is concentrated into the 2%-10% of original volume, extracting solution after concentrating is dropped into staying water, to suppress the growth of red tide algae in the staying water.Per kilogram feldspar water shield rose the seawater lixiviate 0.5-2 days with 30-50 in the said extracted technology, and the extracting solution that obtains is concentrated into the 2%-10% of original volume, applied in the staying water, and every liter of staying water drops into 2-10 milliliter concentrated solution.
The also available organic solvent of above-mentioned solvent, as ethanol, acetone, ether, chloroform or methyl alcohol etc., per kilogram feldspar water shield rose ethanol, acetone, ether, chloroform or methyl alcohol lixiviate 6-48 hour with 2-5, after the extracting solution that obtains is concentrated into the 10%-20% of original volume, apply in the staying water, every liter of staying water drops into 1-5 milliliter concentrated extracting solution.
Therefore, the extracting solution of feldspar water shield is as the application that suppresses the red tide algae.
The present invention makes full use of the feldspar water shield in the feldspar water shield plant, and economical and efficient, good, the easy operation control of ecological security effectively suppress the particularly growth of middle Skeletonemacostatum of ocean harmful algal algae.
Embodiment
The embodiment of the invention describes the present invention in detail with the representative of middle Skeletonemacostatum as the red tide algae.
The preparation method of the feldspar water shield extracting solution of Skeletonemacostatum is in the inhibition of the present invention: with sterilization seawater lixiviate feldspar water shield, adopt the rotary evaporation method to be concentrated into the 2%-10% of original volume the extracting solution that obtains, extracting solution after concentrating is dropped into staying water, to suppress the growth of red tide algae in the staying water.Another kind of scheme is: per kilogram feldspar water shield rises sterilization seawater lixiviate 0.5-2 days with 30-50, and the extracting solution that obtains is concentrated into the 10%-20% of original volume, applies in the staying water, and every liter of staying water drops into 2-10 milliliter concentrated solution.Another kind of scheme is: per kilogram feldspar water shield rose ethanol, acetone, ether, chloroform or methyl alcohol lixiviate 6-48 hour with 2-5, apply in the staying water after the extracting solution that obtains being concentrated into the 10%-20% of original volume, every liter of staying water drops into 1-5 milliliter concentrated extracting solution.Said extracted liquid can adopt rotary evaporation method etc. to concentrate.
