Description

Seaweed farming method using steel slag {SEAWEED CULTIVATION METHOD USING BASIC OXYGEN FURNACE SLAG}

1 is a process chart of the seaweed aquaculture method using steelmaking slag according to the present invention.

The present invention relates to a method for farming algae using steelmaking slag, and more particularly, collecting spores from seaweeds such as seaweed, kelp, and the like, separating spores from spores and transplanting the separated spores into steelmaking slag. Afterwards, the seaweeds are cultured by spraying and dropping the ocean, so that the spores of the seaweeds not only promote growth by ingesting T-Fe contained in the steelmaking slag, but also the cultured seaweeds induce fish's forgery. The present invention relates to a method for farming algae using steelmaking slag that can save fishing grounds and raise fishermen's income, and also maximize the economic effect by recycling industrial steelmaking slag.

In general, the algae that make up the marine forest in the coastal waters of Korea are large brown algae. Among them, brown algae such as brown seaweed and E. coli are spores released during reproduction, swim in seawater, and come into contact with reefs.

In this way, in addition to the spores spontaneously made according to the nature of nature, the spores of seaweeds can be collected by artificial methods and transplanted into artificial reefs as necessary.

Such artificial methods include a method of collecting and attaching spore sacs to natural reefs or natural reefs to be attached and attached to spores before releasing spores, and implanting seaweeds and seaweeds into ropes and ropes and tying them around artificial reefs. The method of attaching seaweed to seaweed and administering it to the sea is mainly performed.

However, these methods are cumbersome tasks with human hands, and there are considerable difficulties in applying them to a wide area.

For the above reason, the above method is not used in a wide range of reef areas and artificial reef areas, and the reefs and seaweeds for the ocean ranching and the algae community are limited to one drop, indicating the effectiveness of the method. .

Along with these problems, the reefs of the East Sea and South Sea have recently occurred, and the natural reefs have been turned to white because they are covered with lime algae that cannot be eaten by marine organisms that feed seaweeds.

As a result, aquatic organisms that live by feeding algae are unable to live, and moreover, fish that live in shelters and seaweeds have also lost their living environment.

For reference, slushing phenomenon refers to the disappearance of seaweeds from the coastal rock area and the white calcite algae sticking to the rocky area. When it occurs, seafood that eats algae disappears and fisheries are devastated.

The cause of the tidal flat recording is believed to be the rise of water temperature due to abnormal temperature and the inflow of pollutants from the land.

The present invention has been devised to solve the above problems, it is possible to maximize the economic benefit by recycling the steelmaking slag of industrial by-products as a nest for growing algae. T-Fe contained in steelmaking slag promotes the growth of algae and forms a colony of algae in the sea area, which induces the aquatic life of the fish and the infestation of the living fish by providing refuge and spawning places in these environments. The purpose is to form a fishery.

In addition, by implanting the spores of the algae in the steelmaking slag, by spraying and dropping to the ocean to form the algae, the farming method is made more convenient and faster, the work efficiency according to the algae culture will be improved In addition, it aims to increase fishery income by allowing large-scale algae farming in a wide range of regions.

In addition, by providing a nest for the algae can grow in order to cope with the recording of the sea, there is another purpose to make the algae grow safer and healthier.

In order to achieve the above object, the algae aquaculture method using the steelmaking slag of the present invention, the step of collecting seaweed that can obtain spores, such as seaweed and kelp, collecting the seaweed spore sachets in the seedling workshop, the collected seaweed spore sac Drying in the shade, filling the water tank with seawater, preparing steel slag, rinsing the dried algae spore sac in seawater and soaking in the water tank for 20 to 60 minutes, when the spores are separated from the seaweed spore sac Extracting the spore sachets from the tank, adding steelmaking slag to the water tank and stirring it from time to time to attach seaweed spores to the steelmaking slag, and removing and spraying the steelmaking slag with the spores from the water tank and spraying it into the seawater. It is done.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a process chart of the algae aquaculture method using the steelmaking slag according to the present invention, the step of collecting seaweed to obtain spores such as seaweed, kelp and the like (S10), and collecting the algae spore sachets in the seedling workshop (S20) Drying the collected algae spore sac in the shade (S30), Filling the seawater in the water tank, Preparing the steelmaking slag (S40), Rinse the dried algae spore sac in sea water and soaked in the water tank for 20 to 60 minutes Laying step (S50), when the spores are separated from the algae spore sachets step (S60) to deliver the spore sachets from the water tank, the steel slag is added to the water tank and stirred occasionally to attach seaweed spores to the steelmaking slag (S70), spores Take out the transplanted steelmaking slag from the water tank is sprayed and dropped into the seawater through the step (S80) is made of the algae farming.

Hereinafter, in the embodiment of the present invention will be described by taking an example of "seaweed" which is one of the representative seaweeds.

First, the seaweed will be described.

Seaweed is a frond plant with distinct root, stem, and leaf distinctions. It is distributed throughout the coast of Korea, but it is not distributed in areas strongly affected by Korean and warm currents, and it breeds from spring to summer.

In addition, seaweeds inhabit rocks near the low tide (the boundary between the sea and land at the time of low tide), but tend to inhabit deeper areas in the south and shallower areas in the north, and are harvested mainly from winter to spring. The most delicious to.

In addition, seaweed is a year-old and has a difference depending on the region, but generally grows in autumn and winter, and breeds in the spring and summer. Yooder germinate soon and spend summer as spouse.

Sprouting and growth of spores are best at 17 ℃ ~ 20 ℃, dormant at water temperature of 23 ℃ or higher, but in the dormant state to withstand high temperature of 30 ℃.

In autumn, when the water temperature drops again below 20 ° C, the spores mature and become apoptotic as a result of sexual reproduction. Apoliposomes grow well at water temperatures below 17 ° C and become single-leaf fluids. The fluid grows to form midribs and combs.

At this time, it grows well at the water temperature of 12 degrees C-13 degrees C or less. And the spores mature and the release of the spores from the spores starts when the water temperature is 14 ℃ or higher, and is released most when the temperature is 17 ℃ ~ 22 ℃.

In detail, the method for cultivating the seaweed in the steelmaking slag, first, the seaweed that can obtain the spores (spawn) in the ocean is selected and collected abundantly.

At this time, it is preferable to collect in late spring or early summer when ocean temperature starts to rise.

In particular, the sea water temperature for the easy release of seaweed spores from seaweed ear is suitable for 14 ℃ ~ 22 ℃, it is optimal when before and after 17 ℃.

Only the seaweed ears are collected separately from these seaweeds, and the collected seaweed ears are transported to the seedling workshop.

At this time, the above work should be carried out below 23 ℃ temperature, seaweed ears and seaweed ears should not rub each other, it should be prohibited to wash with water.

 The seaweed ear is as large and thick as possible, the color of the edge is dark brown or dark brown, the lighter and more mucus is healthy, so it is important to screen and collect.

Then, the collected seaweed ears are dried in the shade, but it is important to note that the first seaweed spores are dried for several hours without moisture, but not too long, and the second seaweed spores are separated from each other. Finally, never expose it to direct sunlight.

The water tank is filled with seawater (17 ° C to 23 ° C) to prepare steelmaking slag.

At this time, the steelmaking slag is preferably used having a size of about 5cm.

The reason is that most of the industrial by-product steelmaking slag comes out about 5cm in size, and it should be about that size, so that algae nourish and grow.

In addition, steelmaking slag having a size of 5 cm or less also comes out a lot of weight is not used because it does not overcome the current in the ocean.

The next step is to slightly rinse the dried seaweed in seawater and soak it in the water tank for 20 to 60 minutes.The reason for rinsing the seaweed in seawater is to remove the foreign matter attached to the dried seaweed. When put in the water tank is to prevent foreign matter from entering the sea water.

When soaked in water tank for 20 to 60 minutes as described above, seaweed spores are naturally separated from seaweed ears, and only the separated seaweed ears are removed from the water tank, and then the steelmaking slag prepared in advance is added to the water tank and stired slowly from time to time.

Then, as described above, the seaweed spores flow to the steelmaking slag (inoculation) while flowing, and after 1 hour, the steelmaking slag is slowly dried.

The dried steel slag is transferred to the place where it is to be farmed, and it is dropped by spraying to the required area (seaweed farming place) using a ship or a small amount by a diver.

At this time, the steel slag of less than 5cm may be mixed and dropped together when dropping the steel slag with seaweed spores attached without spores (inoculation).

The reason is that the seaweed spores released in the sea water naturally adhere to the steelmaking slag (inoculation), so that the natural seaweed culture is made in addition to the artificial seaweed culture.

As described above, the steelmaking slag implanted with seaweed spores sinks to the bottom of the ocean and setstles, and as the time passes, the seaweed spores transplanted germinate and grow.

At this time, a plurality of seaweed spores attached (inoculated) to the steelmaking slag dropped and sprayed in the ocean appear different growth rate depending on the germination time of the leaves.

On the other hand, the optimum water temperature for seaweed growth is 10 ℃ ~ 13 ℃, and grows best between December and February, and it is influenced by the flow of algae and currents (Landscape waters, which is the intersection of the current and the Korean wave) due to the strong seasonal winds. Good up and down flow improves the quality and reduces the damage of pests.

As described above, if the seaweed grows completely, you have to harvest the seaweed to be used for food, as the harvesting method is harvested in Japan and harvested, cut crops.

Japanese harvest means that the seaweed grows in a short place where the growth water temperature is relatively high and 15 ℃ or less, so that harvesting is done at this time.

솎 Negative harvesting means harvesting from early growth where there is a difference in growth in long periods of water temperature below 15 ° C (more than 50 days), and harvesting the rest after further growth.

Leaf crop harvesting is obtained by cutting off the top of the growth zone in the middle of the stem and leaves of seaweed, and the remaining part is regenerated.

In particular, the method is effective when the number of germination is small.

The seaweed culture method using steelmaking slag is made through such methods and procedures, and the seaweed spores ingest the T-Fe content contained in the steelmaking slag to promote growth. Induce them to save fisheries and raise fishermen's income.

On the other hand, the steelmaking slag used to transplant the seaweed spores in the present invention refers to a non-metallic product generated in the process of manufacturing steel by smelting pig iron in the converter, the component ratio of T-Fe (32.1%), CaO (46.1%) , Al2O3 (8.2%), MgO (6.3%), S (0.08%), TIO2 (1.5%), CaO / SiO2 (3.44%), and it is used as an aggregate for the concrete. 6.2%)), etc., T-Fe is 5 times more than it is, so it promotes photosynthesis, which is effective in promoting the growth of algae, which shortens the growth period of aquatic plants, improves the consistency of roots and improves tolerance of leaves. It can improve resistance to pests caused by contamination.

Seaweed culture method using the steelmaking slag of the present invention, after collecting the spores from seaweeds such as seaweed, kelp, etc., separating the spores from the spores, and transplanted separated spores into steelmaking slag, and then sprayed to the ocean As a method of dropping the seaweeds, the farming method is more convenient and quicker, which not only improves the working efficiency of the seaweeds, but also makes it possible to grow the seaweeds in a wide range of regions, thereby increasing fishermen's income. It can increase the effect.

 In addition, it is possible to maximize the economic benefits by recycling the industrial by-product steelmaking slag to the nest where algae grows. T-Fe contained in steelmaking slag promotes the growth of algae and forms a colony of wakame and seaweeds in the sea area, and provides fish and livelihoods to live in this environment, and to provide refuge and spawning places in these environments. Induces the effect of forming a fishery.

In addition, by providing a nest for the algae can grow with steelmaking slag in order to cope with the sounding of the algae, there is an effect that the algae can grow more safely and healthily.
