Description

Loose spray red and green tide removal apparatus

The present invention relates to a vessel-type red tide and algae removal device having an ocher spraying function, more specifically, by forcibly lowering the surface water to be dispersed in the deep sea and at the same time by spraying the ocher solution to quickly remove the red tide and green algae The present invention relates to a marine red tide and an algae removal device having an ocher spraying function.

As is well known, nutrients composed of phosphorus, nitrogen, and organic substances from detergents, phosphate, livestock, and plant waste and waste water due to pollution by domestic sewage, livestock wastewater and factory wastewater form the body of phytoplankton or seaweed. It is a fundamental factor in the growth of red and green algae, and more than 80% of these nutrients flow from land.

Recently, red tide and red tide, which are in the north along the south and east coasts, are becoming a highly diseased phenomenon that occurs frequently on the Korean peninsula coastline. Experts believe that red tide and green algae rise due to large inflows of wastewater and wastewater along with industrial development. It is believed that it is.

In general, red tide and green algae are mostly caused by large amounts of fish excretion feed residues in polluted rivers or river farms, and the proliferation and diffusion of red tide and green algae causes great problems in the ocean when: .

When the amount of sunshine increases and nutrients such as nitrogen (N), phosphorus (P), and iron (Fe) are high, the water temperature diffuses through mass propagation when the temperature is maintained at 20-25 ° C.

Since red and green algae generated in the ocean are photosynthetic metabolism, it is spreading with the rise of water temperature and eutrophication during the summer when sunshine increases.

These red and green algae are adsorbed by the gills of fish in the marine ecosystem and asphyxiate, causing death and depletion of oxygen.

In other words, red tide and green algae are organic substances in the water system and act as lethal elements for fish and shellfish due to the depletion of aquatic oxygen during metabolism by microorganisms.

In particular, Cochlodinium, a kind of phytoplankton, has the nicknames of Korean red tide and green algae. When coclodinium (15 ~ 20㎛), one tenth the diameter of the hair, is breeding, the seawater becomes dark red.

As a solution for this, the applicant has filed a patent for "ship type red tide and green algae removal device and method thereof", which has been registered as Korean Patent No. 0767189.

The above patent discloses that the surface water with elevated water temperature is agitated and sprayed to the lower layer in the sea to block photosynthesis, which is the ecological environmental condition of red tide and green algae, and to reduce the dissolved oxygen of surface water so that the metabolic conditions of aerobic microorganisms do not survive. To prevent and eliminate outbreaks.

On the other hand, as a result of using the patent in actual field, it has been proved that the effect can be further improved by adding ocher.

In other words, when the ocher is introduced, the empty space between the ocher particles adsorbs and decomposes impurities and contaminants to enrich oxygen and emit far infrared rays. Adsorption and sinking into the sea is effective in removing red and green algae, which has been applied to the red and green algae removal work in the past.
