Abstract
The present invention belongs to the field of water treatment, particularly to a method for inhibiting red tide algae by making use of enteromophalinza and application thereof. The method for inhibiting the growth of the red tide algae comprises the following steps that: the enteromophalinza is first pulverized and made into particles or powder; then, the particles or the powder is loaded into a nylon bag with good water permeability, and the nylon bag with the particles or the powder is put into seawater to be treated according to the proportion of 0.5 to 2 gram per liter of the seawater; after several days, the nylon bag containing the enteromophalinza particles or the enteromophalinza powder is taken out of the water body to avoid secondary pollution. The enteromophalinza is used as an inhibiting material for inhibiting the growth of the red tide algae; the inhibition ratio of the enteromophalinza is above 95%. The enteromophalinza is the pulverizing object of enteromophalinza plants. The method for inhibiting red tide algae by making use of enteromophalinza and the application thereof of the present invention have the advantages of good algae inhibiting effect, cheap materials, convenient operation, easy control, good ecological safety, etc., are widely used in the water bodies of coast zones, ports, sea-water bath fields, aquaculture bases, etc., and control the red tide; in addition, the materials are easily obtained.
Description
Technical field
The invention belongs to water treatment field, relate in particular to a kind of methods and applications of inhibiting red tide algae by enteromorpha.
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 red tide suppresses technology and mainly comprises cupric ion method, modified clay method and microbial method.Existing cupric ion (the Cu that utilizes
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 edible enrichment of people the hydrocoles of cupric ion, can be detrimental to health.Weedicide can be killed other plant in the Marine ecosystems when killing the red tide algae, make water ecosystem destroyed, and ecological functions disappear.Clay can adsorb red tide algae dust kicked up by somebody walking in front and drop to the seabed, thus the growth of control red tide algae.But the clay consumption is big, causes trucking costs big, thereby has limited the use of this method.Utilize some specificity to infect the bacterium of red tide algae or virus (phycophage) though also can suppress the growth of red tide algae within the specific limits, but these microbial growths are difficult to regulation and control, thereby utilize it to suppress that the growth of red tide algae is difficult to effectively control in the ocean.
Summary of the invention
The purpose of this invention is to provide that a kind of ecological security is good, the methods and applications of the inhibiting red tide algae by enteromorpha of economical and efficient, 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 edge pipe Enteromorpha to the red tide algae.Technical scheme of the present invention is to suppress raw material with the crushed material of edge pipe Enteromorpha (particle or powder) as the red tide algae to suppress the growth of red tide algae.
The method of inhibition red tide algae growth of the present invention is: edge pipe Enteromorpha is pulverized made particle or powder earlier; reinstall in the good Nylon Bag of water-permeable; and the ratio that restrains with every liter of seawater 0.5-2 drops in the pending seawater; after treating a couple of days, the Nylon Bag that edge pipe Enteromorpha particle or powder are housed is taken out to avoid secondary pollution from water body.
The crushed material of edge pipe Enteromorpha suppresses the application that material suppresses the growth of red tide algae as the red tide algae, and described edge pipe Enteromorpha is an edge pipe Enteromorpha plant.
The present invention has advantages such as effect of algae restraint is good, and material is cheap and easy to get, easy to operate, be easy to control, ecological security is good, thereby is widely used in the water bodys such as littoral zone, harbour, bathing beach, aquaculture base, realizes the effective control to red tide.
Embodiment
Edge pipe Enteromorpha of the present invention as the application method that red tide algae inhibition material suppresses the growth of red tide algae is: at first edge pipe Enteromorpha is made particle or powder with pulverizer, behind the good Nylon Bag of the water-permeable of packing into then, ratio with every liter of seawater 0.5-2 gram drops into pending seawater, to suppress the growth of red tide algae in the pending seawater water body; After the growth of red tide algae is suppressed, the Nylon Bag that edge pipe Enteromorpha powder is housed is taken out from water body.
During use, drop into 0.5-2 gram edge pipe Enteromorpha in per 1 liter of staying water, 2-10 days usually, the red tide algae promptly was suppressed in the water body, and edge pipe Enteromorpha is taken out, and the edge pipe Enteromorpha after avoiding rotting produces secondary pollution.
Below with the be represented as example of the middle Skeletonemacostatum in the common and main red tide algae as the red tide algae.
Embodiment
1.5 gram edge pipe Enteromorpha particles are packed in the good Nylon Bag of water-permeable, put into 3 liters of red tide algae culturing liquids, natural lighting, 25 ℃ of conditions are after following 3 days, and middle Skeletonemacostatum density is 5% of control group, and promptly inhibiting rate is 95%.
With 3 gram edge pipe Enteromorpha powder pack into water-permeable good put into above-mentioned water body, the same terms was cultivated 3 days, this algae density has reduced by 99%; Reduced by 99.7% after 6 days.
With 6 gram edge pipe Enteromorpha powder pack into water-permeable good put into above-mentioned water body after, the same terms was cultivated 3 days, this algae density has reduced by 99.9%.After the red tide algae Be Controlled, edge pipe Enteromorpha is taken out from water body, avoid producing secondary pollution.
Usually it is many to feed intake, and particle is thin, and the time of putting into staying water is short, can take out from water body in general 10 days, if disposable input edge pipe Enteromorpha powder is too much in the water body, will dissolve too much organism in the water body, and then water transparency descends.
Claims (2)
1. the method for an inhibiting red tide algae by enteromorpha is: edge pipe Enteromorpha is pulverized made particle or powder earlier; reinstall in the good Nylon Bag of water-permeable; and the ratio that restrains with every liter of seawater 0.5-2 drops in the pending seawater; after treating a couple of days, the Nylon Bag that edge pipe Enteromorpha particle or powder are housed is taken out to avoid secondary pollution from water body.
