Description

Metal salt aqueous solution composition, its preparation method and use

[0001] The present invention relates to a metal salt aqueous solution composition, and more particularly, to a metal salt aqueous solution composition capable of purifying the air by removing volatile organic compounds and odors, a method for producing the same, and a use thereof.

[0002]

[0003] The environment we live in is polluted with air containing volatile organic compounds (VOCs) and various bacteria and molds.

[0004] The above volatile organic compounds (VOCs) include benzene, toluene, and xylene, and are not only highly toxic, but can also cause mutations and cancer even in very small amounts.

[0005] In particular, benzene is a carcinogen and is known to cause leukemia and lymphoma, and toluene and xylene are known to cause kidney and liver damage as well as brain dysfunction when habitually inhaled (MO Bachmann and JE Myers, Soc Sci Med 40, 245, 1995). Recently, environmentally friendly regulations on these substances have been implemented in the US and Japan through the "Pollutant Release and Transfer Register (PRTR)" system, which legislates the emission, movement, and registration of environmental pollutants within the country, and in the European Union, they are managed through the REACH system that has been implemented since 2004. Although our country also manages volatile organic compounds through related laws and regulations, there is still an insufficient response plan for evaluating the concentration of hazardous substances emitted or researching reductions.

[0006] In addition, air pollution caused by bacteria and mold, etc., causes unpleasant odors in clothing and interior products that are widely used in daily life, causing great discomfort.

[0007] In addition, sick building syndrome, which has been continuously reported in the media recently, is a serious problem that causes serious harm not only to adults but also to children with weak physical resistance by lowering indoor air quality through the release of harmful substances such as volatile organic compounds from building materials such as wallpaper, furniture, and flooring.

[0008] Accordingly, the public interest in improving air quality has been increasing in recent years, and this social atmosphere is demanding environmentally friendly products that are pleasant and harmless to the human body, not only for the surrounding living environment but also for daily necessities.

[0009] Various methods have been proposed to treat volatile organic compounds and bacterial odors, but post-treatment methods based on photocatalysis and adsorption are currently being proposed and utilized. Representative materials include titanium dioxide as a photocatalyst, and activated carbon and charcoal as adsorbents. Titanium dioxide is the most widely used photocatalyst among the photocatalysts studied to date, as it is easy to manufacture and stable. Activated carbon exhibits high organic matter adsorption capacity.

[0010] As a conventional technology for purifying the air, Korean Patent Publication No. 2011-0073072 discloses a catalyst for removing volatile organic compounds by irradiating an electron beam on a titanium dioxide photocatalyst to modify the surface of the photocatalyst, thereby increasing light absorption and photoactivity under visible light, and Korean Patent Publication No. 2011-0072844 discloses a method for removing volatile organic compounds using carbon fiber. However, the titanium dioxide photocatalyst has a low organic matter adsorption rate, and the activated carbon takes too long to purify the air, making it difficult to see a great effect in practice. In addition, when titanium dioxide, activated carbon, charcoal, etc. are contained, there is a problem that the unique color is included, which greatly limits the use.

[0011] Korean Patent Nos. 2397381 and 2351872 are inventions regarding a composition having high liquid stability using a metal chloride salt and an iron salt and having an air purifying function that can purify the air by removing volatile organic compounds and odors. Although the air purifying and odor removing functions are excellent, there was a problem that a fine white powder remained in the product using the composition, which deteriorated the aesthetic appearance of the product.

[0056]

[0057] Hereinafter, a preferred embodiment of the present invention will be described in detail. First, in describing the present invention, specific descriptions of related known functions or configurations will be omitted to avoid obscuring the gist of the present invention.

[0058] The terms "about," "substantially," and the like used in this specification are used in a meaning that is at or close to the numerical value when manufacturing and material tolerances inherent to the meanings mentioned are presented, and are used to prevent unscrupulous infringers from unfairly exploiting the disclosure in which exact or absolute numerical values ​​are mentioned to aid understanding of the present invention.

[0059] The 'metal salt aqueous solution composition' of the present invention refers to an aqueous solution composition in which a water-soluble metal salt is ionized in water and does not maintain a solid state.

[0060]

[0061] The present invention provides a metal salt aqueous solution composition comprising a water-soluble metal salt, wherein the water-soluble metal salt is a divalent metal salt and satisfies the following (1) to (4).

[0062] (1) The viscosity of the metal salt aqueous solution composition is 1.04㎟ / s or more at 20℃,

[0063] (2) The metal salt aqueous solution composition does not form a precipitate at 0 to 80°C.

[0064] (3) The metal salt aqueous solution composition has no metal corrosion properties.

[0065] (4) Water-soluble metal salts maintain a transparent state even in a dry state.

[0066] The above water-soluble metal salt is a divalent metal salt, and uses a metal chloride salt or / and a metal sulfate salt. The metal contained in the water-soluble metal salt is zinc, manganese, copper, magnesium, and aluminum. As for the metal chloride salt, zinc chloride, manganese chloride, copper chloride, magnesium chloride, and aluminum chloride can be used, and as for the metal sulfate salt, zinc sulfate, manganese sulfate, copper sulfate, magnesium sulfate, and aluminum sulfate can be used.

[0067] It is preferable to use two or more of the above water-soluble metal salts among zinc, manganese, copper, magnesium, and aluminum.

[0068] The metal salt contained in the above metal salt aqueous solution has a mechanism of decomposing volatile organic compounds (VOCs) and harmful substances in the air through oxidation by Mcl2 (M is a transition metal such as Mn, Zn, Cu) or / and MSO4 (M is a transition metal such as Mn, Zn, Cu), which are active ingredients of the multi metal sol, and directly acting on harmful bacteria to decompose the cell membrane and interfere with the electron transport system of the harmful bacteria, thereby sterilizing them.

[0069] That is, metal salts dissolve the cell membrane of harmful bacteria, interact with enzymes within the cells, blocking the metabolic function of nutrients, i.e., the inflow and excretion of nutrients, and blocking the respiratory function of harmful bacteria, thereby inhibiting the production of APT (adenosine triphosphate) within the cells, thereby destroying their growth and regeneration abilities and killing harmful bacteria.

[0070] In addition, metal salts are strongly reactive substances that fundamentally remove harmful gas components by decomposing or changing odorous components and neutral odor components into odorless compounds through chemical reactions such as oxidation, reduction, and neutralization with basic odorous components and neutral odor components.

[0071] The above metal salt is a metal with very high electropositive properties that causes a reduction reaction to generate hydrogen (H) from water molecules in the air, and reacts with ammonia (2NH3) gas to form an odorless ammonium salt, thereby eliminating bad odors.

[0072] The above metal salt causes a reduction reaction that generates hydrogen (H) from water molecules in the air, and at this time, it reacts with the neutral odorant formaldehyde gas and is converted into the harmless component bicarbonate, which acts to decompose HCHO (formaldehyde).

[0073] The above metal chloride salts or / and metal sulfate salts may be used as hydrates to increase their solubility in water.

[0074] The above metal salts of zinc, manganese, copper, magnesium, and aluminum have deodorizing properties and the ability to decompose volatile organic compounds, and each has excellent ability to remove specific deodorizing substances and specific volatile organic compounds. For example, zinc metal salts are effective in removing formaldehyde, ammonia, and trimethylamine, and manganese metal salts are effective in removing formaldehyde and trimethylamine.

[0075] The above copper metal salt is effective in removing odorous substances and volatile organic compounds, and is also effective in removing specific substances such as formaldehyde, trimethylamine, and acetic acid.

[0076] In the above metal salt aqueous solution composition, it is preferable that the metal chloride salt or / and metal sulfate salt be contained in an amount of 1 wt% or more for functionality, and more preferably 1 to 25 wt%. If the content of the metal chloride salt or / and metal sulfate salt exceeds 25 wt%, a precipitate may be formed.

[0077] The content of the metal chloride salt or / and metal sulfate salt of the above metal salt aqueous solution composition can be adjusted depending on the intended use, and the content of the metal chloride salt or / and metal sulfate salt can be adjusted by diluting the metal salt aqueous solution composition containing 1 to 25 wt% of the metal chloride salt or / and metal sulfate salt.

[0078] The above metal salt aqueous solution composition may further include metal salts such as metal oxide salts and metal carbides in addition to metal chloride salts or / and metal sulfates, but it is preferable that the metal chloride salts or / and metal sulfates are contained in an amount of 95 wt% or more, and more preferably, 100 wt% of the metal chloride salts or / and metal sulfates are used.

[0079] The above metal salt aqueous solution composition may further include a metal salt such as a metal oxide salt or a metal carbonate salt for functionality, and when the metal salt such as a metal oxide salt or a metal carbonate salt is included, it is preferable that it be contained in an amount of less than 5 wt%.

[0080] The metal salt aqueous solution composition including a metal chloride salt or / and a metal sulfate salt of the present invention is formed by dissolving the metal chloride salt or / and the metal sulfate salt using water as a solvent, and it is preferable that the water be purified water.

[0081] As described above, the metal salt aqueous solution composition can be manufactured by adding two or more kinds of the chloride metal salts of zinc chloride, manganese chloride, copper chloride, magnesium chloride, and aluminum chloride, and the sulfate metal salts of zinc sulfate, manganese sulfate, copper sulfate, magnesium sulfate, and aluminum sulfate in a set amount in water according to the intended use, and by adjusting the amount of the metal salt, the pH can be adjusted to 3 to 6 to suppress the occurrence of sediment, thereby preventing the air purification function, deodorization, antibacterial property, and antiviral property from being reduced.

[0082] The above metal chloride salt and / or metal sulfate salt has the function of increasing the solubility of other compounds when contained in water, and has the characteristic of maintaining a transparent state by absorbing moisture when exposed to air even in a dry state, and the metal salt aqueous solution composition of the present invention can increase the usability of the metal salt aqueous solution composition of the present invention by optimizing various conditions such as composition components, pH control, and viscosity, with the characteristic of not corroding metals.

[0083] As described above, a metal salt aqueous solution composition can be manufactured into a highly stable metal salt aqueous solution composition through a manufacturing method including a metal salt aqueous solution manufacturing step, an injection step, a mixing step, and a cooling step.

[0084] The above metal salt aqueous solution manufacturing step is a step of manufacturing each metal salt aqueous solution according to the water-soluble metal salt contained in the auxiliary tank. The number of auxiliary tanks may be formed equal to the number of water-soluble metal salts contained in the metal salt aqueous solution composition to be manufactured, or each metal salt aqueous solution may be manufactured using one auxiliary tank.

[0085] It is preferable that the above auxiliary tank be formed so that the temperature can be increased at a constant rate and a pH regulator and a metal ion sequestering agent can be added.

[0086] The above auxiliary bath can produce each metal salt aqueous solution by heating to a set temperature of 70 to 95°C at a heating rate of 1 to 3°C / min, and it is preferable to set each metal salt aqueous solution to the same temperature.

[0087] In order to shorten the heating time of the auxiliary tank, the purified water to be introduced into the auxiliary tank can be heated to a certain temperature in advance and then introduced into the auxiliary tank, thereby shortening the time for the metal salt aqueous solution manufacturing step.

[0088] The above pH regulator and metal ion sequestering agent can be added as needed. The pH regulator and metal ion sequestering agent can be contained in separate tanks, and then the pH regulator and metal ion sequestering agent can be added to each auxiliary tank through a mechanical device.

[0089] Formic acid, citric acid, maleic acid, etc. can be used as the pH adjusting agent, and imidazole, EDTA-2NA, EDTA-4NA, polyphosphate, diethylenetriamine, etc. can be used as the metal ion sequestering agent.

[0090] When the above pH regulator and metal ion sequestering agent are added, it is preferable to add 0.3 to 2 parts by weight of the pH regulator and the metal ion sequestering agent to 100 parts by weight of the metal salt aqueous solution composition.

[0091] In each auxiliary tank, purified water is added, and then, depending on the final concentration of the metal salt aqueous solution composition to be manufactured, each water-soluble metal salt is added and stirred while raising the temperature to manufacture the metal salt aqueous solution.

[0092] The above injection step is a step of sequentially injecting each manufactured metal salt solution into the main tank.

[0093] In the above injection step, stability can be increased by sequentially adding water-soluble metal salts with low solubility to the main tank.

[0094] The above mixing step is a step in which the metal salt solution set in the main tank is completely added, and then the solution is stabilized for 120 to 300 minutes while maintaining the set temperature of 70 to 95°C, by stirring for a certain period of time to prevent a plurality of water-soluble metal salts from reacting with each other.

[0095] The above cooling step is a step of cooling the mixed metal salt aqueous solution at a constant speed to 10 to 40°C. If the cooling speed is too fast, precipitates may occur, so it is preferable to cool the solution slowly while stirring at a cooling speed of 0.5 to 1.5°C / min in the above cooling step.

[0096] The above cooling step may be performed in the main tank, or a cooling tank with a separate cooling device may be formed and the cooling step may be performed in the cooling tank.

[0097] As described above, the method for manufacturing a metal salt aqueous solution composition according to the present invention is to manufacture a metal salt aqueous solution composition having a viscosity of 1.04 mm2 / s or more at 20°C and maintained in a stable state by maintaining the temperature during each metal salt aqueous solution manufacturing and mixing step while raising the temperature in the metal salt aqueous solution manufacturing step, and controlling the cooling speed during the cooling step.

[0098] The viscosity of the above metal salt aqueous solution composition must be 1.04㎟ / s or more at 20℃ to exhibit the antibacterial and deodorizing functions required in the present invention, and it is preferable to control it to 1.20㎟ / s or less at 20℃, and it would be more preferable if it is 0.65㎟ / s or more at 40℃.

[0099] The temperature raised in the above metal salt aqueous solution manufacturing step can be set to be the same as the temperature maintained in the above injection step, thereby shortening the stabilization time of the above mixing step.

[0100] The manufacturing conditions described above are important factors that not only ensure that the metal salts are stably dissolved in the solvent without forming precipitates, but also maintain a transparent state even in a dry state.

[0101]

[0102] As described above, the metal salt aqueous solution composition according to the present invention can be applied to various purposes, and not only has antibacterial and deodorizing effects, but is also transparent after drying, so there is no discoloration of the intended product or process problems due to precipitation, and thus it can be used for various purposes such as deodorants.

[0103] The metal salt aqueous solution composition of the present invention can be used as is, according to the intended use, by adding more water and spraying it on a toilet, washbasin, etc., and can be used to provide air purifying function, deodorizing property, antibacterial property, and antiviral property to wallpaper, sheets attached to the outside, and advertisements by coating or immersing them, and can be applied in various ways to all products requiring air purifying function, deodorizing property, antibacterial property, and antiviral property, such as pet peeve pads and pee sand.

If the content of natural plant particles is high, mixing will be difficult, and if the content of natural plant particles is too low, the drying time will be long in the drying step.

[0139] The mixing ratio of the above binder and water can be adjusted depending on the binder used, and the mixture can be mixed to a viscosity that can be sprayed, and the mixture can be sprayed so that the set binder content is contained.

[0140] Additionally, the above mixing step may be performed by incorporating the binder into the metal salt aqueous solution composition and then spraying it onto natural plant particles.

[0141] It is preferable to mix the above natural plant particles and the metal salt aqueous solution composition containing the binder in a weight ratio of 1:2 to 4.

[0142] The above drying step is a drying step for drying the mixture, and can be dried into vegetable particles containing water-soluble metal salts and binders through a conventional drying process.

[0143] The above drying step is a step of grinding the dried mixture into particles of the same size as sand particles, and can be ground using a conventional grinding process.

[0144] It is preferable to grind the above plant particles to an average particle size of 0.1 to 3 mm.

[0145] It is preferable that the total content of water-soluble metal salts in the metal salt aqueous solution composition included in the above natural plant particles be 0.01 to 0.5 wt%. If the content of water-soluble metal salts in the metal salt aqueous solution composition is high, it is preferable to dilute it with purified water before use.

[0146]

[0147] The plant-based particles with excellent antibacterial and deodorizing properties according to the present invention as described above can be used as cat litter by maintaining a sand-like shape through a binder and imparting antibacterial and deodorizing properties through a water-soluble metal salt.

[0148] The plant-based particles having excellent antibacterial and deodorizing properties of the present invention can be used as cat litter only, and can be used by mixing with sand. By mixing the plant-based particles having excellent antibacterial and deodorizing properties and sand in a weight ratio of 50:50 to 100:0, cat litter having antibacterial and deodorizing properties can be manufactured.

[0149]

[0150] As described above, the metal salt aqueous solution composition according to the present invention can be mixed with a microbial culture solution and applied to a substance that generates a strong odor, such as livestock manure, to produce a metal salt aqueous solution composition containing microorganisms that can rapidly reduce odor and promote decomposition.

[0151] The metal salt aqueous solution composition of the present invention creates an environment for the survival, growth and development of microorganisms at a pH of 3 to 5.

[0152] It is preferable that the metal salt aqueous solution composition containing the above microorganisms satisfies the following characteristics (1) and (2).

[0153] (1) The above microbial culture solution contains microorganisms that can survive in the form of endospores or exospores at pH 3 to 5 and produce bacteriocin.

[0154] (2) The number of microorganisms in the metal salt aqueous solution composition is 10 8 CFU / ㎖ or more, and the metal salt in the metal salt aqueous solution contains 1 to 10 wt% of the metal salt.

[0155] The above microbial culture solution preferably contains microorganisms that produce bacteriocin and have excellent survival rate at a pH of 3 to 5. Bacterocin is a natural, non-toxic preservative and is an antimicrobial protein composed of a protein or a complex of protein and carbohydrate produced by many gram-positive and gram-negative bacteria. In particular, since nisin, one of the bacteriocins, was approved by the U.S. FDA in 1998 for use in processed cheese spread foods, bacteriocins have been recognized as antimicrobial agents that can be used in the food industry.

[0156] The above microbial culture solution is a substance that promotes the decomposition of objects that generate odors, such as livestock manure, and reduces the generation of odors in the long term, and includes microorganisms including Bacillus, Lactobacillus, Actinomycetes, and Yeast.

[0157] The above Bacillus strains have the characteristic of reducing odor by suppressing harmful bacteria by producing bacteriocin, an antibacterial substance, and Bacillus polyfermenticus, Bacillus licheniformis, Bacillus amyloliquefaciens, Bacillus megaterium, Bacillus subtilis, Bacillus thuringiensis, Bacillus coagulans, Bacillus clausii, Bacillus atrophaeus, etc. can be used as microorganisms that support compost decomposition.

[0158] When using multiple species of the Bacillus strains disclosed above, the present invention preferably contains two or more species of Bacillus strains to facilitate the activity of the Bacillus strains in various environments, and more preferably, 4 to 6 species of Bacillus strains are used.

[0159] The above Lactobacillus strain has the characteristic of reducing odor by producing bacteriocin, an antibacterial substance, like the above Bacillus strain, and Lactobacillus paracasei, Lactobacillus Buchner, Lactobacillus plantarum, Lactobacillus rhamnosus, etc. can be used as microorganisms that support compost decomposition, and it is preferable to contain at least one of the Lactobacillus strains disclosed above.

[0160] The above actinomycetes are microorganisms that support decay and secrete antibiotics, and the above yeasts are microorganisms that promote decay, and Pichia fermentans, Candida ethanolica, Saccharomycopsis schoenii, Saccharomyces cerevisiae, etc. can be used. It is preferable to contain at least one of the yeasts disclosed above, and more preferably, it contains at least two.

[0161] The above microbial culture solution can be manufactured by culturing a complex of microorganisms including Bacillus, Lactobacillus, Actinomyces and Yeast in water at 30 to 40°C, adding starch, molasses or corn syrup used as microbial nutrients and salt for mineral supply, and then culturing for 3 to 7 days.

[0162] The above Bacillus, Lactobacillus, Actinomyces and Yeast can be used in either powder or liquid form, and the above microbial culture solution contains 1 X 10 of each of Bacillus, Lactobacillus, Actinomyces and Yeast after cultivation. 4 It is desirable to contain more than CFU / ㎖, and the total number of microorganisms in the composition containing the metal salt aqueous solution is 10 8 If the CFU / ㎖ is higher, sufficient odor removal and decomposition effect can be expected.

[0163] In addition, the microorganism must be able to survive in a peat mixture state with a pH of 3 to 5 due to the inclusion of the water-soluble metal salt.

[0164] The starch, molasses or corn syrup, and salt contained in the above microbial culture solution should be added in an adjusted amount depending on the Bacillus, Lactobacillus, Actinomyces, and Yeast strains used.

[0165] The Bacillus bacteria contained in the above microbial culture solution are prokaryotes that form endospores in extreme environments, the actinomycetes are prokaryotes that form exospores, and the yeast bacteria are eukaryotes that form exospores.

[0166] As described above, the Bacillus, Lactobacillus, Actinomyces and Yeast contained in the microbial culture solution of the present invention are microorganisms that form spores in extreme environments, and by adjusting the pH of the microbial culture solution to 3.0 to 5.0, an extreme environment can be created for the microorganisms, and in this state, the Bacillus, Lactobacillus, Actinomyces and Yeast survive in the form of endospores or exospores.

[0167] If the pH of the above microbial culture solution is less than 3, microorganisms effective in removing odors may die due to the low pH, and if the pH exceeds 5, various microorganisms other than microorganisms effective in removing odors may proliferate, thereby reducing the odor removal effect.

[0168] When the above-mentioned Bacillus, Lactobacillus, Actinomyces and Yeast are in an endospore or exospore state, they can survive for a long time even in the absence of nutrients, so that the composition including the metal salt aqueous solution of the present invention can be stored for a long time.

[0169] As described above, when Bacillus, Lactobacillus, Actinomyces and Yeast included in the microbial culture solution are contained in a spore state, the storage period of the composition containing the metal salt aqueous solution increases, and when the composition of the present invention is sprayed on livestock manure or compost, the pH rises, causing the microorganisms to germinate in a spore state, promoting metabolic action and promoting decomposition.

[0170] The pH of the above microbial culture solution can be adjusted using a pH adjusting agent such as citric acid or formic acid.

[0171] In the above metal salt aqueous solution composition, it is preferable that the total content of the metal salt be 1 to 10 wt%. If it is contained in an amount less than 1 wt%, the odor reduction effect may be minimal, and if it exceeds 10 wt%, sediment may be generated.

[0172] It is preferable to adjust the pH of the above metal salt aqueous solution composition to 3 to 5 using a pH adjuster, etc., to suppress the formation of sediment and prevent the air purification function, deodorization, antibacterial property, and antiviral property from being reduced.

[0173] The metal salt aqueous solution composition containing the microorganism of the present invention is a mixture of a microbial culture solution that promotes decomposition and a metal salt aqueous solution composition that reduces odor, as described above. It is preferable that the microbial culture solution and the metal salt aqueous solution composition be mixed in a weight ratio of 1:9 to 5:5. When the microbial culture solution is contained in an amount of less than 10 wt%, the decomposition promotion is not greatly improved, and when the metal salt aqueous solution composition is contained in an amount of less than 50 wt%, the odor reduction effect may be reduced.

[0174] The above composition of microbial culture solution and metal salt solution should have a pH of 3 to 5 so that the odor can be neutralized and reduced through decomposition and oxidation. It is preferable that the pH difference between the microbial culture solution and metal salt solution be 0 to 1.

[0175] The above microbial culture solution and metal salt aqueous solution composition should have a pH of 3 to 5 so that the odor can be neutralized and reduced through decomposition and oxidation. Therefore, it is preferable that the pH of the peat mixture be 3 to 5.

[0176]

[0177] A peat mixture containing a metal salt aqueous solution composition containing the above microorganisms can be prepared and used in various ways for livestock purposes.

[0178] The above peat is aquatic plants, mosses, and wetland grasses that have been deposited near the surface and biochemically carbonized, and is also called peat. It is a coal that has not been fully carbonized due to being buried for a short period of time, and is in a state between wood and lignite. It contains more than 50% organic matter, is reddish brown or dark brown, and is porous because it has not been subjected to strong stratum pressure, and has a high moisture content with a porosity of 60-85%. Depending on the material, it is classified as sedimentary peat, fibrous peat, and woody peat, and is abundant in areas with relatively short microbial activity periods in extreme regions. Peat has good moisture absorption, absorption, and deodorizing properties, so it is used for agricultural purposes such as soil conditioners and microbial activity promoters, as well as fertilizers and deodorizers.

[0179] The moisture content of the peat mixture according to the present invention is preferably 10 to 80 wt%. If it is less than 10 wt%, the composting effect may be reduced, and if it exceeds 80 wt%, management may be difficult and it may deteriorate into composted soil. It is more preferable that the moisture content of the peat mixture be 30 to 50 wt%.

[0180] The above peat contains a certain amount of moisture, and after the microbial culture solution and metal salt aqueous solution composition are added, the moisture content of the peat should be adjusted so that the moisture content is 10 to 80 wt%, preferably 30 to 50 wt%.

[0181] It is preferable that the particle size of the above peat mixture be 1 to 15 mm. If the particle size of the peat mixture is 1 mm, it may be difficult to control the moisture content, and if it exceeds 15 mm, usability may be reduced.

[0182] The peat mixture of the present invention is preferably formed by containing the metal salt aqueous solution composition containing microorganisms prepared above in peat, and containing 5 to 50 wt% of the metal salt aqueous solution composition containing microorganisms in the peat, so that the moisture content of the peat mixture is 10 to 80 wt%.

[0183] The metal salt aqueous solution composition containing the above microorganisms should have a pH of 3 to 5 so that the odor can be neutralized and reduced through decomposition and oxidation. Therefore, it is preferable that the pH of the peat mixture be 3 to 5.

[0184]

[0185] The peat mixture according to the present invention is suitable as a livestock bedding, and when used as a livestock bedding, the peat mixture may further contain rice husk and sawdust.

[0186] If the above peat mixture further includes rice husk, it is preferable to mix the peat and rice husk in a weight ratio of 10:90 to 90:10, and if sawdust is further included, it is preferable to mix the peat and sawdust in a weight ratio of 10:90 to 90:10.

[0187] When the peat mixture according to the present invention is used as a livestock bedding, it can reduce the odor of the livestock shed, and by using livestock manure, it can promote odor reduction and decomposition, thereby suppressing diseases in livestock, reducing mortality rate, and increasing productivity.

[0216] As shown in Table 2, in Examples 1 to 5, no precipitate was generated in the temperature range of 0 to 80°C, but in Example 6, a precipitate was generated at 30°C. Therefore, it is preferable that the total content of the metal salt contained in the metal salt aqueous solution composition of the present invention be 20 wt% or less.

[0217] ◎ Deodorization evaluation experiment

[0218] The deodorizing properties of the metal salt aqueous solution compositions of Examples 1 and 4 among the examples manufactured above were evaluated and are shown in Table 3.

[0219]

[0220] Classification Reduction rate (%) Hydrogen sulfide gas Example 188 Example 488 Control group -20 Pyridine gas Example 199 Example 499 Control group 43 Ammonia gas Example 192 Example 494 Control group 21 Acetic acid gas Example 185 Example 485 Control group 33 Trimethylamine gas Example 192 Example 492 Control group 15 Isovaleric acid gas Example 95% reduction after 12 hours Example 4 95% reduction after 2 hours Indole gas Example 95% reduction after 12 hours Example 4 95% reduction after 2 hours Nonenetal gas Example 92% reduction after 12 hours Example 4 91% reduction after 2 hours

[0221] As shown in Table 3, it can be seen that the metal salt aqueous solution composition of the present invention has excellent deodorizing properties for most malodorous substances.

[0222] ◎ Measurement of formaldehyde removal rate

[0223] The formaldehyde removal rates of the metal salt aqueous solution compositions of Examples 1 and 4, which had excellent liquid stability among the examples manufactured above, were measured and shown in Table 4.

[0224] Time Example 1 Example 4 30 minutes 88% 89% 60 minutes 93% 93% 90 minutes 95% or more 95% or more 120 minutes 95% or more 95% or more

[0225] As shown in Table 4, it can be seen that the metal salt aqueous solution composition of the present invention has an excellent formaldehyde removal rate. In the case of Examples 1 and 4, it can be seen that there is no significant difference in the formaldehyde removal rate of 95% or more after 90 minutes.

[0226] ◎ Antibacterial evaluation experiment

[0227] The antibacterial activity of the metal salt aqueous solution compositions of Examples 1 and 4, which had excellent liquid stability among the examples manufactured above, was evaluated and is shown in Table 5.

[0229] As shown in Table 6, it can be seen that the metal salt aqueous solution composition of the present invention has excellent antibacterial properties, and it can be seen that the antibacterial properties are similar to those of Examples 1 and 4.

[0230] ◎ Metal corrosion evaluation test

[0231] The metal corrosion resistance of the metal salt aqueous solution composition of Example 4, which has excellent liquid stability among the examples manufactured above, was evaluated and is shown in Table 6.

The control group was sprayed with water, and the comparative example was a composition containing a metal chloride salt.

[0233]

[0234] As shown in Table 6, in the comparative example, no special corrosion occurred on the aluminum plate, but corrosion occurred on the iron plate and copper plate. It can be seen that the metal salt aqueous solution composition containing the metal sulfate of the present invention and the iron plate, copper plate, and aluminum plate sprayed with water did not cause any special corrosion, and thus the metal salt aqueous solution composition containing the metal sulfate of the present invention does not have metal corrosion properties.

[0235] ◎ Decomposition evaluation experiment

[0238]

[0239] As shown in Table 7, Example 2 showed white spots and powder on the film after drying, but the metal salt aqueous solution composition of Example 1 containing a metal chloride salt did not show any unusual features such as white spots on the film even after drying, indicating that it maintained a transparent state even after drying due to its solubility and did not detract from the aesthetic appearance.

[0266] As shown in Table 9, in Comparative Examples 1-1 and 1-2 using fermented urine, the odor level was 999 from the beginning and did not decrease even after time passed, but in Comparative Examples 1-1 and 1-2, the odor level was 999 at the beginning, but after 30 minutes, the odor level was reduced by half, and the odor level continued to decrease, and after 2 hours, the odor level was 108, which is about 90% less odor, showing that the plant-based particles with excellent antibacterial and deodorizing properties according to the present invention are effective in reducing odor.

[0267] ◎ Antibacterial evaluation experiment

[0268] The antibacterial activity of the plant-based particles with excellent antibacterial and deodorizing properties manufactured above was evaluated and is shown in Table 10.

[0269] * Antibacterial evaluation was performed by measuring the bacteriostatic reduction rate after culturing Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352) for 6, 12, and 18 hours.

[0287]

[0288] As shown in Table 12, in Comparative Example 2, it can be seen that most microorganisms are activated in the microbial culture medium, but in Example 2, which was prepared through pH adjustment, it can be seen that most microorganisms maintain a spore state. In addition, it can be seen that when Example 2 is applied to manure, the microorganisms are activated in a spore state.

[0293] 100g of the manufactured peat mixture was mixed with 100g of livestock manure sample from a broiler farm with an ammonia content of 100ppm or more. The odor condition immediately after mixing, after 1 month, and after 2 months, and the decomposition condition after 1 month were evaluated, and the results are shown in Table 13.

[0294] The moisture content of the peat mixture was calculated as follows after drying the peat mixture in a dryer at 70℃.

[0295] * Moisture content (weight %) = [(Weight of peat mixture before drying - Weight of peat mixture after drying) / Weight of peat mixture before drying] x 100

[0296]

[0297] Usage comparison example 3

[0298] 100g of peat with a moisture content of approximately 20-25 wt% and a particle size of approximately 10mm was mixed with 100g of livestock manure sample from a broiler farm with an ammonia content of 100ppm or more. The odor condition immediately after stirring, after 1 month, and after 2 months, and the decomposition condition after 1 month were evaluated, and the results are shown in Table 4.

[0299]

[0300] Ammonia content (ppm) 1 month after mixing and 2 months of use Example 3000 Usage comparison example 30.43.72.7

[0301] As shown in Table 13, in the case of Use Example 3, it can be seen that the odor is quickly reduced by mixing the peat containing the metal salt aqueous solution composition containing microorganisms with the livestock manure sample, and it can be seen that no odor is generated even after time passes, but in Use Comparative Example 3, the odor is reduced to some extent immediately after stirring, but it can be seen that the odor is generated over time. In the case of the composting state, it can be seen that Use Example 4 has progressed considerably after one month, but it can be seen that Use Comparative Example 3 has slowed down the composting compared to Use Example 3.

[0302] As described above, when using a peat mixture, it can be seen that the odor is quickly reduced and the odor is continuously reduced with the metal salt aqueous solution composition, and it can also be seen that it is effective in promoting composting with a microbial culture solution.
