(Red tides and water bloom remedial method according to the concentration of algae using salicylate shell and algae,

The present invention relates to a red tide and a green algae remediation method using algae concentration using a remedy consisting of a crustacean shell and yellow loam, and more particularly to a method for red tide and algae remediation using an irradiation step, a measurement step, a water Raman signal (Rs) , A chlorophyll-a concentration calculating step, a manufacturing step, a dilution step, a spraying step and a moving step. The chlorophyll-a value is measured to calculate red tide and green tide concentration, and a suspension suitable for the concentration is prepared and sprayed. The present invention relates to a method of relieving red tides and algae according to the concentration of algae using a phytoplanktic material and an algae material composed of yellow clay, which efficiently copes with green tide.

Since industrialization in the 1970s, the pollution of many lakes and rivers in Korea has been polluted due to the increase of emission pollution sources, and eutrophication such as mass production of birds has frequently occurred, which is becoming a big social problem.

Due to the mass production of cyanobacteria in some lakes that have recently been used as a water source, problems such as hobbies and toxins have arisen.

As the water temperature rises and the water flow becomes gentle in the rivers and lakes, the green algae phenomenon occurs as a result of the massive growth of green algae or blue algae in the water and the watery bodies are green or indigo.

First, it is visually impaired by coloration or scum formation, causing visual discomfort from dead fish, and recreational activities.

Second, from the viewpoint of public health, the harmful effects of cyanobacterial toxins on human body and livestock are caused by this hobby.

Third, ecological destruction of native ecosystems destroys native animals, habitat migration, population changes, and food loss.

Fourthly, there are economical losses due to local economic loss due to recreational activities and travel disruption, agricultural water and lack of industrial water, loss of livestock caused by avian toxins, dead of wild animals, It affects animal health by the death of fish and aquatic organisms due to reduced dissolved oxygen.

In addition, the production of cyanobacteria, odor generation, filtration paper clogging, inhibition of coagulation sedimentation, and excess chlorine treatment during the process of hydrothermal treatment generate THM and adversely affect the water source.

As described above, algae that adversely affects aquatic organisms are classified into simple single cells and multicellular microorganisms that carry out carbon assimilation, such as cyanobacteria, green algae, and diatoms.

Cyanobacteria are the predominant algae in eutrophicated waters and have nitrogen fixation ability. They form dormant spores that are resistant to adverse environment and endure. When the environment improves, they germinate and reproduce, and because of their high water temperature and high adaptability to pH, Mass proliferation can occur. In addition, green algae proliferate from late spring to early fall season, and in the waterworks facilities, they form a filtration membrane of sedimentation or slow filter paper. If they multiply rapidly, they may smell water and close the filter paper.

In addition to chlorophyll-a and b, diatoms contain pigments such as diatomaceous earth and xanthophyll, and they reproduce everywhere from seawater to fresh water and soil. They are floating and adherent. Lt; / RTI > If it is excessive, it interferes with aggregation and precipitation, and clogs the filter paper.

Red tide, on the other hand, means that phytoplankton, especially phytoplankton, propagate in large quantities and change the color of the sea water to red or yellowish brown. When organic matter is abundant in the water and the amount of sunshine and water temperature is appropriate, red tide appears. Because of the large amount of oxygen consumed for the decomposition of the massive reproductive plankton, fish are exposed to a large number of dead fish due to lack of oxygen. In addition, mass reproductive plankton attaches to the gills of fish and suffocates the fish, and the monocotyledon, coccolinium, kills the fish by poisoning the poison.

Red tides are mostly occurring in the coastal waters, such as when the surface water temperature is rising, when the nutrients are greatly increased due to the influx of fresh water due to heavy rain, rainy season, or when the sea water is not mixed well due to the windless condition.

In Korea, during the rainy season in July and August, the amount of pollutants on the land has flowed into the sea, causing eutrophication of seawater.

Currently, red tide alerts are issued when a red tide phenomenon occurs at the National Fisheries Research and Development Agency and Fisheries Research Institute, and there is a risk that fish damage will occur due to the presence of large or toxic species. Red tide alarms include red tide warning, red tide warning, red tide breaking, and red tide cancellation. If the density of red tide creatures is large, the damage is expected to be great, but not necessarily. Therefore, special attention should be paid to the occurrence of toxic red tide organisms when red tide alarms are issued. This is because the problem of paralysis and diarrhea is a problem other than mass mortality.

The red tide and green tide described above occur annually and are mainly used for redemption work using loess, but they suffer from a lot of losses due to a large amount of equipment, cost, red tide and green tide concentration, Equipment, systems, and remedies.

Some of the combinations listed above are described.

The crust shell powder is prepared after crushing for 10 minutes at 1000 ° C or higher in a gas furnace after washing and drying, and is relatively uniform and minute in size.

Since the raw ore powder has high ion exchange capacity, it can be applied as a remedial material and it can be used very easily because the interstitial cations react with organic minerals.

The carpow fiber is a natural fiber, and each of the fibers independently forms a thin tube. Since the cell is smaller than the water molecule size and is lipophilic, it is strong enough to withstand penetration of water and rich in perfection, Reacts and coagulates or adsorbs them, thereby effectively removing the algae or red tide microorganisms. In addition, it is cost-effective and economical.

The remediation method and effect according to the concentration will be described below.

The concentration of chlorophyll-a is 50 mg / L when the concentration is 5 to 10 mg / m 3, 25 mg / L when the concentration is 20 to 40 mg / m 3, 100 mg / A formulation with a solubility of 200 mg / L is produced.

The reason for blending certain combinations according to the above concentration is to reduce the consumption of resources and to reduce the cost by using an appropriate amount of the combination according to the remedial efficiency.

The formulation is formulated with an additional 500-3000 mg / L of loess.

The constituents of the loess are metal compounds such as silicon, aluminum and iron, and are used as an adsorbent in natural processes and water treatment processes due to their affinity for inorganic ions.

Hwangto is known to be a natural material obtained from nature and is widely used. Recently, heavy metals such as lead and arsenic contained in Hwangtoe can threaten sea ecosystem and it is known that organic matter sprayed together can cause eutrophication, For this reason, the additional amount of yellow loess is limited by the concentration and the appropriate amount is used.

In the above manufacturing step, the suspension is prepared by adding 1/20 to 1/100 of the amount of seawater to the formulation.

In order to make the method suitably prepared by adding an appropriate amount of seawater to the formulation, the above-described seawater quantitation is inferior in the remediation efficiency due to the imbalance of suspension and seawater quantitation.

The preparation step is prepared by adjusting and selecting the powder size.

The powder size is preferably 200 to 350 mesh.

It is necessary to use an appropriate size depending on the powder size, and when the powder size is exceeded, the remediation efficiency falls.

When the concentration of chloroporphol-a is less than 5 mg / m3, the measurement zone is moved.

When chlorophyll-a is measured at a low concentration, chlorophyll is used to eliminate waste by using the remediation material and to increase the remediation efficiency by putting resources into different measurement areas.
