Description

Floating artificial reef{FLOATING TYPE ARTIFICIAL FISH REEF}

The present invention relates to an artificial reef, and more particularly, to a floating artificial reef that can solve the environmental pollution problem of marine ecosystems and induce spawning and growth of marine organisms to increase fishing.

Artificial fish reefs are intended to increase the production of mass-produced organisms by inducing the growth of marine organisms. According to the 「Artificial Reef Facility Project Execution and Management Regulations」 of the Ministry of Food, Agriculture, Forestry and Fisheries of the Republic of Korea, artificial reef refers to various structures that are installed to artificially create a spawning and habitat for aquatic organisms in the water, sea ranch, sea forest, and marine forest. do. In addition, artificial reefs are classified into fish reefs for fish or shellfish and algae depending on the type of marine organisms living around them. Fish reefs for fish refer to artificial reefs installed for spawning, growth and fishing of fish, and shellfish and algae reefs for shellfish breeding, growth and harvesting, attaching and breeding seaweeds, or artificially transplanting seaweed seeds. It refers to an artificial reef to be installed.

In general, artificial reefs are manufactured in a block shape that is artificially protruding from the coastal sea floor. Conventional block-type artificial fish reefs are manufactured using cement, gravel, sand, etc. as their main materials, and their useful life is only 2-3 years on average, which is very short. In addition, since there are not many voids between cement, gravel and sand, it takes at least 6 months for the spores of seaweed to attach. In the case of using a conventional artificial reef, the growth of seaweed is slow and the community density of the seaweed is low. Therefore, there is a limit to greatly increasing the production of various marine organisms. In addition, artificial fish reefs are installed in the water, causing water pollution and other problems of disturbing the marine ecosystem.

1 is a diagram schematically showing a construction form of a floating artificial reef according to a first exemplary embodiment of the present invention. 2 is a perspective view schematically showing the configuration of a tube 110 into which a chelate composition is injected according to the present invention. 1, the floating artificial reef 100 according to the first embodiment of the present invention includes a floating body 150, a fixture 160 connected to the floating body 150, and the fixture 160 It includes a tube 110 connected to, and optionally includes a bundle (bunch) 170 that is independently connected to the tube 110 to the fixture 160. In the present specification, when the terms such as connection and combination are used, it includes a case in which two components are directly connected, as well as a case in which other components are interposed between these two components.

The float 150 may be a buoy that can float on the sea level, and the fixture 160 may be a rope for fixing. For example, the floating body 150 is connected to one end of the fixture 160 through the first connecting means 152. On the other hand, the tube 110 into which the chelating composition including humic material, fecal fossil and organic feed is filled and injected is connected to the fixture 160 through the second connecting means 162. On the other hand, the bunch 170 made of fibrous material may be connected to the intermediate height of the fixture 160 through the third connecting means 172. In addition, the bottom surface of the floating body 150 is connected to the anchor 180 through the fourth connecting means 182, due to the anchor 180 settling on the sea floor, the floating body 150, the floating body 150 It is possible to prevent the tube 110 and the bunch 170, which are independently connected to each other, from leaving their original positions even at a strong flow rate. In one exemplary embodiment, the first to fourth connecting means 152, 162, 172, 182 may be clamps, fasteners, and connecting strings, but are not limited thereto.

2, the tube 110 connected to the fixture 160 is a tube body 120 made of a vinyl or plastic material, a closing member 130 blocking both ends of the tube body, and the tube body 120 It includes a plurality of pin-holes 140 formed at predetermined intervals. As an example, the tube body 120 may have a rectangular or long cylindrical shape, and may be formed of a polyvinyl chloride (PVC), a polyolefin such as polyethylene or polypropylene, a vinyl or plastic material such as polyurethane, but limited thereto. It doesn't work.

The tube body 120 has a plurality of pin-holes 140 formed at predetermined intervals. As an example, the diameter of the pin-hole 140 may have a size of 0.1-2 mm, and may be formed in a plurality of the tube body 120 with an interval of approximately 3-20 cm. On the other hand, both ends of the tube body 120 may be formed with a closing member 130 capable of completely separating the inside and the outside of the tube body 120 by heat fusion, an adhesive, a binding string, or the like.

Before closing both ends of the tube body 120, a chelating composition including a humic material, a fossil shell, and an organic feed may be injected and filled into the inside of the tube body 120. As an example, the chelating composition may include 20-30 parts by weight of a humic substance, 20-30 parts by weight of a pebble, and 50-60 parts by weight of an organic feed. If necessary, the chelating composition is compressed and molded into a cylinder having a length of 20-100 mm × width of 20-100 mm × height of 10-30 mm or a cylinder having a diameter of 20-100 mm × length of 20-100 mm, and then molded into a tube body ( 120) It can also be injected or filled inside. The term parts by weight, unless stated otherwise, refers to the relative weight ratio between the ingredients to be blended.

In an exemplary embodiment, the humic material constituting the chelating composition may be selected from the group consisting of humic acid, fulvic acid, ulmic acid, and combinations thereof. The humus constituting the chelating composition is, for example, from carbonaceous materials such as humus, peat moss, peat and/or leonardite, or wood materials such as lignin. It can be obtained, but is not limited thereto. In an exemplary embodiment, the humic material can be extracted from briquettes or lignin.

Peat is a carbonaceous material biochemically carbonized by deposits of incompletely decomposed material near the surface of the surface of aquatic plants such as wetlands and swamps, moss, and wetland grass. Peat is a porous carbonaceous material that contains more than 90% of organic matter and has a porosity of approximately 60 to 85%. It has a yellowish brown or dark brown color because it is a carbonaceous substance in which the organism is not completely decomposed due to the inhibition of the activity of microorganisms that decompose organisms in wetlands or swamps where excessive moisture is supplied. Peat is excellent in moisture absorption, absorption and odor properties, contains a small amount of inorganic components, and is relatively light, so it can be easily handled.

Peat is a carbonaceous material that has been altered by biochemical carbonization by thickly depositing the fluid of a plant or tree in a basin. It is formed by decomposition of lignin and cellulose, which are the main components of plants, at the surface. After the peat layer is formed in the swamp, soil is deposited on the upper part, moisture is removed by earth pressure and geothermal heat, and fiber disappears due to condensation of vegetable natural polymers, and vegetable polymers contain organic carbon and oxygen from the outside. It is formed by partial oxidation.

These carbonaceous substances contain humic substances denatured by decomposition and polymerization of soil organic substances by microorganisms, etc., in other words, organic substances called humus substances. In general, soil organic matter is a non-humus, such as polysaccharides, proteins, lipids, amino acids, etc., in the process of humification of immature organic matter and unripe organic matter in the process of humification as tissues of animals and plants are decomposed by microorganisms, etc. And a humic material, which is an organic material in which the non-humic material is further changed to form a brown-black organic colloid.

A humic substance is a polymer compound in which a condensed ring is formed as soil organic matter is decomposed, condensed, polymerized, and oxidized for a long period of time, and is an organic colloidal state having a size of approximately 1-100 nm. Humic substances derived from carbonaceous substances such as coal briquettes are categorized in color, degree of polymerization, molecular weight, number of functional groups such as carboxyl group (-COOH) and hydroxy group (-OH), number of carbon and oxygen, degree of substitution, water solubility, etc. It can be classified into humin (humin), humic acid, fullvic acid, and ulmic acid according to the scientific characteristics. The humic material constituting the chelating composition according to the present invention may be selected from the group consisting of humic acid, fulvic acid, ulmic acid, and combinations thereof.

Humic substances such as humic acid, fulvic acid, and ulmic acid can be classified according to the polymerization structure, ring and chain shape, etc., and have an average size of approximately 5-50 ㎚, and the three-dimensional structure and size are determined during the humicization process. . These humic substances contain organic ligands, which are converted into a chelated state by combining with metal salts or amino acids produced from the fossil powder and organic feed described later.

Humic substances such as humic acid, fulvic acid, and ulmic acid have a macromolecular structure, such as a phenolic hydroxy group formed by the influence of aromatic compounds having benzene rings such as fatty acids and lignin, which are fat-soluble components with little functional group in the center and low polarity. It is a free ligand having both a fat-soluble functional group and a water-soluble functional group such as an alcoholic hydroxy group (ROH) and a carboxy group (RCOOH) formed by the influence of amino acids or sugar compounds, which are highly polar and water-soluble natural polymers. Since organic ligands have very good cation exchange properties, cation exchange reactions with various cationic substances in the vicinity can be performed to generate chelate complexes.

For example, humic acid is a polymer compound that is hardly soluble in water, but is soluble in alkaline agents such as potassium hydroxide (KOH) and sodium hydroxide (NaOH). It is usually brown-black-brown, and contains a large number of functional groups in the molecule, so that various trace elements are easily bonded to each other, so that the oxidized portion has a negative charge. Humic acid is a complex aromatic macromolecule in which amino acids, amino sugars, peptides, aliphatic compounds, etc. are complexly bonded between aromatic rings and rings, and nitrogen, oxygen, hydroxy groups, carboxyl groups, etc. are variously bonded to the aromatic ring. have.

Fulvic acid is a highly soluble compound that is well soluble in water regardless of its acidity, and has a yellow or orange color. Fulvic acid has aromatic and aliphatic structures, both of which are broadly substituted with oxygen-containing functional groups. Fulvic acid is a corrosive component in which the number of oxygen is greater than that of humic acid, but has a small number of carbons, and contains a large number of functional groups, particularly carboxyl groups, hydroxyl groups, and ketone groups (C=O).

For example, the humic material used according to the present invention has a negative charge. Therefore, minerals having a positive charge contained in the fossil powder and organic feed are combined with the humic material. Minerals combined with humic substances can be easily consumed by marine organisms, including algae and plankton, and can induce them to gather around these marine organisms.

For example, one of the humic acids of humic substances and promote the growth of marine organisms and activate the source microorganism, increasing the degree and absorbing nutrients effective and, in particular, a nitrate main nitrogen form is absorbed into the bird (NO ₃ ^- Improve the utilization rate of N). Humic acid helps the growth of marine life by accumulating trace elements and organic matter necessary for marine life including algae.

Fulvic acid has a stronger acidity than humic acid and has high hydrophilicity, so it can dissolve minerals that humic acid cannot dissolve. In addition to dissolving minerals, fulvic acid can help the growth of marine organisms by acting as a nutrient medium.

That is, the humic material contained in the chelating composition according to the present invention can be extracted in a chelate form that is good for marine organisms to absorb nutrients such as minerals and amino acids by using humic materials such as humic acid, fulvic acid, and ulmic acid, which are organic ligands. I can. In particular, humic substances, which are free ligands in the form of complex compounds that form coordination bonds with amino acids and the like contained in fossil powder and organic feed, function as an important inorganic electrolyte component in marine animals. Organic ligands derived from humic substances stabilize the microbial phase inside fish, shellfish, and zooplankton, thereby enhancing the efficiency when ingesting fossil powder and organic feed, and has antibacterial and anti-viral activity.

As described above, the humic material can be prepared from a carbonaceous material such as briquette. First, the carbonaceous material is pulverized. In order to prepare a humic material having an organic ligand, briquettes are supplied to a pulverizing device to have an appropriate size, for example, an average particle size of 0.5 mm or less, for example, 0.01-0.5 mm, preferably Is pulverized to a size of 0.05-0.5 mm. At this time, wind or hot air is supplied from the lower part of the pulverizing device to classify only the dust-type briquettes and the briquette fractions having an appropriate size. When the size of carbonaceous particles such as briquettes is less than the above-described range, a humic material having an organic ligand can be easily extracted, but the processing cost of the carbonaceous particles may increase. In addition, when the size of carbonaceous particles such as briquettes exceeds the above-described range, a reaction time for extracting a humic material having an organic ligand may be lengthened.

The pulverized briquettes are fed to the reactor to extract the free ligand. For example, the reactor may be a compartment type or ladle type extraction reactor, and may be processed into a humic material in such a reactor. Of the humic substances contained in carbonaceous substances, since humin is insoluble in water regardless of acidity, the humic substance composed of humic acid, fulvic acid, ulmic acid, and a combination thereof through the above-described extraction process is in the form of an organic ligand. Can be extracted.

In the case of extracting humic substances such as humic acid, fulvic acid, and ulmic acid having organic ligands from the pulverized carbonaceous material, special treatment may not be required when extracting fulvic acid, but the extraction solvent in a neutral state, for example, water It is necessary to change the pH of the reactant to alkaline in order to extract the humic acid, which is not soluble in water. The alkalizing agent used is not particularly limited, and may be selected from the group consisting of calcium oxide (quicklime, CaO), calcium hydroxide (slaked lime, CaOH), sodium hydroxide (NaOH), potassium hydroxide, and combinations thereof. For example, the pH of the reactant may be adjusted to about 8-12, preferably 8-10 by adding an alkalizing agent, and the alkalizing agent may be used in a concentration of about 5-30% (w/v) in a solvent.

If necessary, the reactor is stirred using a stirring means such as a magnetic bar, and the reactant is at least 50° C., for example, at a temperature of 80-100° C. and at least atmospheric pressure, for example, at least 12 hours at 1-2 atm, preferably React for 24-72 hours. Accordingly, the humic material contained in the pulverized carbonaceous material swells, and the humic material having an organic ligand is extracted while being dissolved in the solvent. Through this process, not only a humic substance that is well soluble in water, which is an extraction solvent, but also a polymer, which is a humic substance that is difficult to dissolve in water, is hydrolyzed in the form of small molecules of humic acid, fulvic acid, and ulmic acid.

In an alternative embodiment, when extracting a humic material such as humic acid, fulvic acid, or ulmic acid from the carbonaceous material, gypsum (CaSO ₄ nH ₂ O) is added to the reactor with or independently of the alkalizing agent. I can. The solvent and gypsum have good solubility in water used as an extraction solvent compared to the metal salts or metal ions contained in the fossil powder or organic feed to be described later, or amino acids produced by corroding organic feed. Accordingly, organic ligands contained in humic substances such as humic acid, fulvic acid, and ulmic acid extracted through the above-described process react with gypsum to form a calcium chelate complex. In this process, sulfuric acid liberated from gypsum reacts with metal salts or metal ions, for example, calcium carbonate contained in the pebbles to convert to calcium sulfate, thereby preventing the pH of the chelate composition from lowering. Calcium sulfate converted in this process may react again with organic ligands of humic substances that have not reacted with the humic substance by the crushed fossil powder or the decayed organic feed.

However, if the amount of gypsum, that is, calcium sulfate is too large, since the chelate composition changes to acid, it may be difficult for marine organisms to consume the chelate composition according to the present invention. Therefore, it may be desirable to add gypsum in a proportion of 5-10 parts by weight based on the humic material.

Through the above-described process, a humic substance in the form of an organic ligand that has a small molecular weight or is well soluble in water can be extracted. For example, humic acid contains a number of anions, and the condensed structure collapses and expands into a colloidal state by repelling each of the anionic molecules when the pH is increased by adding an alkalizing agent. As it changes, it is possible to extract the humic acid in the form of an organic ligand.

On the other hand, fulvic acid is well soluble in water, but can be easily soluble in water at the pH of an acidic condition. In order to extract fulvic acid, an acidifying agent, which may be an inorganic strong acid such as nitric acid or hydrochloric acid, or an organic acid such as lactic acid, acetic acid, fumaric acid, formic acid, propionic acid, malic acid, and citric acid, may be added to the solvent. For example, by adding an acidifying agent, the pH of the reactant may be adjusted to about 3-5, but is not limited thereto.

At this time, the humic material derived from the carbonaceous material may be classified into humic acid, fulvic acid, ulmic acid, etc. according to color, degree of polymerization, molecular weight, number of functional groups, degree of substitution, water solubility, and the like. If necessary, the humic material extracted through the solvent extraction method may be selected according to specific gravity and separated into humic acid, fulvic acid, and ulmic acid.

In an alternative embodiment, humic materials such as humic acids may be obtained from carbonaceous materials such as humus, peat, peat and briquettes containing natural lignin-based materials, for example briquettes. For example, humic acid extracted from briquettes or lignin produced in natural swamps has a very low carbon content, but relatively has a glue component. If you burn a humic material extracted from briquettes or lignin, it does not catch fire, but it produces a lot of smoke, does not break, and has a lot of debris. By using such characteristics, it is possible to obtain a humic material in which a void structure is formed in various directions when it is processed under conditions of high temperature and high pressure and then rapidly cooled.

Specifically, the humic material extracted and separated through the above-described solvent extraction method and specific gravity selection method is put into a pressure tank having a high heat of 200-260°C and a high pressure of 200-600 kgf/㎠, and the pressure tank is instantaneously in a vacuum state. When the door of the door is opened, the humic material is sprayed and crushed into a powder form. At this time, when rapid cooling (-30℃~-20℃), a number of honeycomb-type voids with many voids are formed in the humic material. If this process is repeated several times (eg, 2-10 times), a humic material in which pores in various directions (eg, 6 directions) are formed is obtained. In this case, components such as ammonia, which are included in the excrement of marine organisms and cause odor, may react with the humic material or may be trapped in the voids inside the humic material.

The chelate composition also includes a pebble powder. Shellfish, etc. secrete a protein-bound metal, such as calcium, from the epidermal cells of the coat membrane covering the soft body toward the shell. This secreted metal component dissolves in seawater for a long time and binds with carbon dioxide, resulting in calcium carbonate and calcium phosphate. And a material present in the form of crystals in the form of inorganic metal salts such as magnesium carbonate is a crushed fossil. For example, shellfish can be obtained from shell graves deposited on the seafloor rising to land in the process of converting the sea to land by volcanoes and tectonic fluctuations tens of millions of years ago.

These metal salts contained in the pebble are separated into metal ions and anions in seawater, and the metal ions form a chelating complex with a humic substance. Metal mineral components that have been converted into chelated complexes can be easily consumed by marine organisms. According to one exemplary form, the fossils may be injected into the tube body 120 in a powder form. In this case, a crushed fossil powder may be used to have a size of approximately 0.1-0.5 mm. For example, the pebble powder may have a size of 0.1-0.3 mm by separating it into 40 mesh. In another alternative embodiment, the fossils may be injected into the tube body 120 in bulk. In this case, the fossils may have a size of approximately 0.1-0.5 cm. When using the above-described range of the fossil powder or mass, the metal component can be efficiently extracted.

The chelating composition also includes an organic feed. In an exemplary embodiment, organic feed may be obtained by processing food waste such as leftovers, slaughter residues, and food by-products. Since such components can be recycled, the tubular artificial fish reef according to the present invention can contribute to minimizing environmental pollution due to food waste that is difficult to treat. For example, organic feed can contain leftovers, slaughter residues, and/or food by-products (by-products of milk factories, confectionery factories, and food processing plants that use soy/flour/rice flour) at approximately 40-75°C. It can be obtained by maturing and processing for 30 days or more, for example 90-120 days.

The organic feed includes a liquid component and a solid component, and the content of the liquid component may be, for example, 10 to 20% by weight. Solid components include organic substances such as proteins, polysaccharides, and fats contained in food waste, as well as macro elements such as sodium, calcium, magnesium, phosphorus, potassium, and chlorine, and trace elements that are metal components. Some components such as amino acids, monosaccharides, oligosaccharides, fatty acids, etc. from which organic substances are hydrolyzed during the ripening process may be included. The organic feed may include a solid organic feed or a liquid organic feed. At this time, the content of the liquid component may vary depending on the type of food waste, which is a raw material of the organic feed, the content of the liquid component, and the process of ripening. For example, the content of the liquid component in the liquid organic feed may be 10-60% by weight, but is not limited thereto.

Accordingly, the organic feed injected into the tube body 120 together with the above-described humic material is further corroded by the humic material and contains a large number of monomer components such as amino acids and mineral components. The amino acid and mineral components react with the humic substance to form a chelating complex compound, and are discharged to the outside through the pin-hole 140, and the chelating complex compound can be consumed by marine organisms.

In addition, sodium and potassium, as well as nutrients such as nitrate, phosphate, and silicate, and gases such as oxygen, nitrogen, and carbon dioxide, are dissolved in seawater. Therefore, when the mineral component contained in seawater flows into the tube body 120 through the pin-hole 140, it reacts with the humic substance to form a chelating complex compound, and the formed chelating complex compound is the pin-hole 140 It can be consumed by marine organisms as it is leaked to the outside.

That is, according to the present invention, when a chelating composition comprising a humic substance having an organic ligand, a fecal fossil having a metal salt, and an organic feed is injected into the tube body 120, the metal salt contained in the fecal fossil and the amino acid contained in the organic feed And the mineral component reacts with the organic ligand contained in the humic material to form a chelating complex, and the formed chelating complex is discharged to the outside through the pin-hole 140 to be consumed by marine organisms, and the growth and reproduction of marine organisms Can induce.

Components such as sodium and potassium contained in seawater introduced into the tube body 110 also react with organic ligands of the humic substance to form a chelating complex, and may be discharged to the outside of the tube body 120. By chelation of mineral components contained in seawater, whitening caused by these mineral components can be prevented and minimized. In addition, since the humic material includes a porous structure formed in a number of directions, there is an advantage of minimizing marine pollution by collecting components such as ammonia that cause odors from excrement of marine organisms. In addition, oxygen contained in the pores formed in the molecular structure of the humic material can be supplied to marine organisms.

In addition, the seawater pressure increases according to the depth of the seawater, and there is an advantage of promoting a chelating reaction between a humic substance having an organic ligand and a metal salt in the shell fossil and/or an amino acid or mineral component in an organic feed under the elevated pressure. I can. In addition, among the metal salts contained in the fossils, calcium carbonate is not well soluble in water. However, since carbon dioxide contained in seawater can be converted into carbonic acid, calcium carbonate is relatively easily dissolved, and calcium carbonate can be easily combined with an organic ligand of a humic substance to form a chelating complex compound.

In an alternative embodiment, the floating artificial reef 100 may further include a bunch 170 that is independently connected to the fixture 160. The bunch 170 may be manufactured using synthetic components such as vinyl or plastic, but since these materials are not decomposed, there is a risk of disturbing the marine ecosystem. Accordingly, the bunch 170 may be manufactured using an eco-friendly material, which is a natural fiber such as coconut palm fiber that is decomposed after a certain period of time.

The bunch 170 is made of hard and non-perishable fibers, and can serve as a hiding place for plankton and the like. In an exemplary embodiment, the bunch 170 may be connected in a manner that is suspended in an intermediate position of the fixture 160. To this end, the fixture 160 and the bunch 170 may be connected through a third connection means 172 such as a clamp, a fastener, or a fixing string. Accordingly, the chelated complex compound flowing out through the pin-hole 140 formed in the tube body 120 is constructed by the floating artificial reef 100 due to the bunch 170 disposed near the tube 110 It can be prevented and minimized from leaving the area.

In another exemplary embodiment, the bunch 170 may be filled with a filler including the aforementioned humic material, crushed stone and, optionally, organic feed. In this case, the filler punches the central part of the bunch 170 with a diameter of 2-40 mm to form a groove in the center of the bunch 170, fills the humic material and the fecal stone therein, and attaches it to the tube body 120. It could be. In this case, the humic material filled in the bunch 170 may include 30-40 parts by weight, and the shell fossil may include 60-70 parts by weight. Accordingly, calcium generated from the fossils, amino acids and various mineral components of organic feed, and mineral components in seawater are discharged from the inside of the bunch 170 to the outside, and the food of spores such as algae and plankton living around the bunch 170 Becomes.

Hereinafter, the present invention will be described through exemplary embodiments, but the present invention is not limited to the technical idea described in the embodiments.

Example 1: Humic acid extraction and preparation

Put the briquette powder pulverized to a size of 0.05-0.5 mm into the reactor, add water and 5-30% (w/v) alkalizing agent, and react with stirring at 80-120°C for 24 hours at atmospheric pressure. The humic material was extracted. The extracted humic material was separated according to the specific gravity selection method to separate humic acid and fulvic acid. Put the separated humic acid and fulvic acid in a pressure tank with high heat of 200~260℃ and high pressure of 200~600 kgf/㎠, and momentarily open the door of the pressure tank in a vacuum to remove the broken humic acid in powder form. It was rapidly cooled at -30°C to -20°C. This process was repeated several times to extract and prepare humic acid and fulvic acid. In the extracted humic material, the moisture content was 5-10% by weight, the humic acid content was 66-34% by weight, and the fulvic acid content was 7% by weight.

The molecular structure of the humic acid prepared in this embodiment was analyzed by requesting an external organization. 10A is an electron microscope image of the humic acid powder, FIG. 10B is an electron microscope image for EDS analysis of the humic acid powder, and FIG. 11 is a graph showing the EDS analysis result of the humic acid powder. Meanwhile, Table 1 below shows the EDS analysis results for the humic acid powder.

As can be seen from these results, the voids of the humic acid powder form a phase formed in six directions. That is, in the molecular structure of the humic acid powder, voids existed in both front and rear, left and right sides, and upper and lower sides of each unit powder. In particular, since 61.6% of oxygen, which is a humic acid component, is present in the pores, the specific gravity is light and is expected to be able to quickly absorb the gas to be deodorized. That is, it was confirmed that using the humic acid powder, odor components such as ammonia and hydrogen sulfide contained in the excrement of marine organisms can be captured in the pores and chelated to decompose the odor component and quickly deodorize.

Example 2: Evaluation of maturation ability of humic acid powder

(1) Evaluation of swine sludge maturity

The water content was adjusted to 50-60% by mixing solids obtained by dehydrating pig shed sludge (water content of about 70-90%) and organic feed obtained by corroding and processing food waste (water content of about 13%) in a 1:1 ratio. 10-30% by weight of the humic acid powder containing the decomposing enzyme was mixed and deodorized, and the pig house sludge was completely matured by composting at 40-70°C for 20-60 days. As a result of evaluating the maturity of the swine sludge from the maturing pig house, it was confirmed that the maturity was completely maturity.

(2) Deodorization and purification ability evaluation

The humic acid powder extracted in Example 1 was administered to 10-30 parts by weight of the leachate and 10-30 parts by weight of the septic fossil powder to the septic tank leachate, and the deodorization and purification ability were evaluated. In four septic tanks, 20-30 parts by weight of leachate was charged, slowly stirred to deodorize, and a filter tank connected to the last septic tank was filled with humic acid powder and pebble powder at a ratio of about 1:1 and filtered. Table 2 shows the analysis results. It was confirmed that the humic acid powder and the fecal fossil powder reacted to chelate the metal components contained in the fecal fossil, and the content of the harmful ingredient was low, so that it could be used as feed or fertilizer that can be consumed by living organisms.

Example 3: Analysis of feed effect of chelating composition

A chelating composition consisting of 50-60% by weight of organic feed obtained by corrosion and processing of food, 10-30% by weight of humic acid powder, and 10-30% by weight of pebble powder is fermented and fermented in a solid chelating composition and a solid feed. The possibility of using the liquid chelating composition mixed and compressed at a ratio of 1:1 as a feed was evaluated. Table 3 shows the results of analyzing the content of calcium and amino acids after the solid chelating composition is corroded, and Table 4 shows the results of analyzing the contents of calcium and amino acids after the liquid chelating composition is corroded. It was confirmed that mineral components and amino acids react with humic substances and become chelate while maturing, and exist in a form that can be ingested and absorbed by marine organisms.
