Description

  The present invention relates to a snow removal agent obtained by impregnating a wood chip with microorganisms and a metal ion salt and, more particularly, to a method for producing the snow removal agent. Not only can the effect of melting snow be obtained at the same time, but the microorganisms impregnated in the wood chip can act as nutrients on the surrounding plants and soil to improve the quality of the soil, and can be used for soil and crops that are useful for plant growth. The present invention relates to an environment-friendly snow removal agent impregnated with beneficial microorganisms and a method for producing the same.

In recent years, snowstorms in winter have frequently occurred not only in Japan but also worldwide due to global weather changes, etc. Therefore, snow on roads etc. is removed for traffic safety and smooth operation. Therefore, many snow removal agents are distributed in winter.
Generally, a snow removal agent is classified into a snow melting (melting) agent that melts snow directly and a friction agent that cannot melt snow but temporarily increases the frictional force on a snow surface or a frozen road surface.

  Usually, sand or briquette ash is used as the friction agent, but it has the effect of preventing friction by temporarily increasing the frictional force in the initial stage of spreading, but the particles gradually settle down in the deep part of the ice layer. It is buried in the snow when it snows, and it is difficult to expect a great effect due to clogging of distribution pipes and drainage wells, air pollution due to fine particles, vehicle damage due to foreign objects, sand or briquette ash remaining after the snow melts It is inferior in economic efficiency because it requires a lot of workmanship and costs such as cleaning, so it requires frictional forces such as uphill sections, shaded areas, constantly freezing areas, bridge sections without geothermal heat, etc. It is used only in limited areas.

  On the other hand, snow-melting agents are roughly classified into chloride-based snow removal agents and non-chloride-based snow removal agents, and chloride-based snow removal agents have a better snow-removing effect than non-chloride-based snow removal agents. It is the fact that we use snow removing agent.

However, the existing chloride-based snow remover contains chlorine ions (Cl ⁻ ) and iron (Fe) contained in the chloride-based snow remover when it is distributed on road surfaces and bridges for snow removal work. There is a problem that iron chloride (FeCl ² ) is generated while reacting, which corrodes automobiles, reinforcing bars, steel frames and the like.

  In particular, calcium chloride, which is frequently used among chloride-based snow removal agents, induces water pollution and soil acidification when dissolved in water or absorbed by soil, and also helps plants such as plants and crops around roads. It is known as one of the causes of environmental pollution by hindering the growth of plants such as withering.

  In addition, since the snow removal agent to be distributed is randomly swung away over a wide range, a larger amount than the amount actually required for snow removal is distributed, and once used, the snow removal agent is distributed along with the water generated while the snow melts. If it snows or freezes again, it will be necessary to redistribute it. Therefore, a larger amount of snow removal agent is used than the amount required for snow removal during snow removal work, causing problems such as vehicle corrosion and road damage due to an excessive amount of snow removal agent.

  Accordingly, in order to solve the above-described problems, research and development on various environmentally friendly snow removal agents have been progressing. Therefore, the applicant of the present application is the Korean Patent No. 1617935 (April 27, 2016). Through the registration notice), we used wood chips made from waste wood such as trees left after cutting in the mountains and cut ends at the woodworking plant, and used the frictional properties of wood and the sustained release effect of metal ions. I have proposed a snow remover that can be used for a long time.

  However, the conventional technique has a problem that when the temperature rises, the road or road surface looks aesthetically unclean due to the remaining wood chips, and the additional work of collecting the remaining wood chips is inferior in economic efficiency.

Korean Registered Patent No. 1617935 (Registration Notice on April 27, 2016)

  According to the present invention, a wood chip, which is an environmentally friendly material, is impregnated with a metal ion salt and a microorganism to produce a snow removal agent, thereby increasing the frictional force on the snow-covered road surface or road with the wood chip. By melting snow with the metal ion salt impregnated inside, the effect of friction agent and snow melting agent can be obtained together, while the microorganisms impregnated in the wood chip are released to the outside and the surrounding soil and plants In addition to acting as a nutrient component, the wood chips are biodegraded by the microorganisms impregnated in the wood chips at a time when the temperature is no longer necessary and a snow removal agent is no longer needed, thereby recovering the remaining wood chips The purpose of the present invention is to provide an environmentally friendly snow removing agent impregnated with beneficial microorganisms in soil and crops, and a method for producing the same, which does not require additional work. That.

  In order to achieve the object as described above, one embodiment of the present invention relates to an environmentally friendly snow removal agent impregnated with microorganisms beneficial to soil and crops, including wood chips impregnated with metal ion salts and microorganisms. .

  The wood chip is manufactured including a surface treatment step of forming irregularities on the surface of a wooden board; and a crushing step of crushing the wooden board with irregularities formed on the surface into thin plate-like pieces of wood having a thickness of 1 to 20 mm. Good.

The ion solution in which the metal ion salt is dissolved includes magnesium chloride (magnesium chloride), sodium metasilicate, calcium chloride, sodium chloride, and a lithium ion salt. What melt | dissolved the at least 1 or more metal ion salt selected from the group by 1: 0.5-2 mass ratio may be used. At this time, the metal ion salt used includes 100 parts by weight of magnesium chloride and 1 to 10 parts by weight of sodium metasilicate and 1 to 10 parts by weight of lithium ion salt based on 100 parts by weight of magnesium chloride. You can do it.
The microorganism culture solution may be produced by inoculating a medium with one or more microorganisms selected from the group consisting of Bacillus subtilis and lactic acid bacteria.

  Preferably, in the first drying step, the wood chip impregnated with the metal ion salt may be dried at 120 to 140 ° C. for 1 to 2 hours, and in the second drying step, the wood chip impregnated with the microorganism is used. Is preferably dried at 10 to 30 ° C. for 20 to 30 hours.

  According to the present invention, a snow removal agent is produced by impregnating a metal ion salt and a microorganism into a wood chip, which is an environmentally friendly material, so that the microorganism impregnated in the wood chip is released to the outside. It acts as a nutrient on the surrounding soil and plants that are spread and improves the quality of the soil and is useful for plant growth.

  In addition, since the wood chip is biodegraded by microorganisms after a predetermined period of time, there is no need to perform additional work to collect or remove the remaining snow removal agent at a time when the temperature rises and the snow removal agent is no longer needed. It is environmentally friendly because it does not cause secondary environmental pollution.

  Prior to the detailed description of the preferred embodiments of the present invention, the terms and words used in the present specification and claims should not be construed to be limited to ordinary or lexicographic meanings. It should be clarified that it should be construed as a meaning consistent with the technical idea and concept of the present invention.

  Throughout this specification, when a part “includes” a component, this does not exclude other components but may further include other components, unless otherwise specified. Means that.

In this specification, “wood chip” means a small piece obtained by crushing a tree into a predetermined size. In a broad sense, it means a small piece of a tree root, branch, trunk, etc., excluding the leaves of the tree. It may be.
Hereinafter, the environment-friendly snow removing agent impregnated with beneficial microorganisms in the soil and crops of the present invention and a method for producing the same will be described in detail.

  First, in the case of an environmentally-friendly snow remover impregnated with beneficial microorganisms in the soil and crops according to the present invention, the frictional force on the snow-covered road surface or the road surface that has been snowed or frozen by spreading on the road surface is improved, and By melting snow continuously with metal ion salt impregnated in woodchips, it is possible not only to obtain a snow melting (ice melting) effect, but also microorganisms beneficial to the soil and crops are released to the surrounding soil and It can act as a nutrient for plants to improve plant growth and soil quality. Also, when the predetermined time passes and the temperature rises and the snow removal agent is no longer needed, the microorganisms impregnated in the wood chip are activated to biodegrade the wood chip and collect the remaining snow removal agent. This eliminates the need for additional work, improving economic efficiency, and providing biodegraded wood chips as nutrients to the surrounding soil and plants.

  Specifically, in the case of the environment-friendly snow removal agent impregnated with beneficial microorganisms in the soil or crop according to the present invention, wood chips impregnated with metal ion salts and microorganisms may be included.

  The wood chip is a small piece obtained by finely crushing a hard part of a tree such as a tree root, a branch, or a trunk excluding leaves, and as an example, after cutting a cut tree into a plate shape, the surface area of the surface of the wooden board is improved. After forming irregularities for this purpose, this is crushed and used, or, as another example, after manufacturing processed products using trees or trees that are cut down for renewal, planting, etc. A large amount of forestry by-products generated can be crushed and used, and resources that are discarded can be recycled to improve resource efficiency.

  In the wood chip, a metal ion salt having a snow melting effect that melts snow is impregnated in a large number of pores formed in the tree, and when the wood chip is distributed on the road surface or road surface on which snow is accumulated, the metal ion The melting process in which the salt reacts with the snow to melt the snow is continuously progressed, and the metal ion salt impregnated in the wood chip over a predetermined period instead of a moment is gradually discharged to the outside. A sustained release effect that maintains the snow removal effect can be obtained.

  Preferably, the wood chip may be a thin plate-like piece of wood having a length of 1 to 20 mm, and more preferably a thickness of 5 to 10 mm in order to give an appropriate frictional force to the snow or ice road surface. May be 1 to 5 mm, and the form of the thin wooden piece is not particularly limited, and may be various forms such as a balanced quadrilateral, a square, a circle, a sphere, and a polygon.

  The surface area of the wood chip varies depending on the length, thickness, and form of the wood chip. Therefore, the sustained release effect of the wood chip varies, and the wood chip is preferably thin.

  Further, the surface of the wood chip may be flat, but preferably, unevenness may be formed, and the surface area of the wood chip is increased by the unevenness formed on the surface of the wood chip. The snow removal effect can be improved by the large surface area of the chip, and the frictional force of the road surface can be increased by the large surface area.

  As an example, in order to increase the surface area of the wood chip, the surface of the manufactured wood chip may be formed with unevenness, the formed unevenness is formed along a line, or arbitrarily irregular It may be formed. Further, the formed uneven section may be formed in various forms without particular limitation, such as streamline, corrugated, triangular, quadrangular, trapezoidal, polygonal, etc. The uneven section is not a single form. The various forms mentioned may be repeated and arranged irregularly.

  More specifically, the metal ion salt contained in the wood chip serves as a snow melting (melting ice) that melts snow directly, and is generally used as a snow removal agent that melts snow. Any of these may be used without any particular limitation, but preferably magnesium chloride, sodium metasilicate, calcium chloride, sodium chloride, and sodium chloride. At least one selected from the group consisting of lithium ion salts may be included.

  More preferably, among the metal ion salts, more environmentally friendly magnesium chloride is used as a main raw material, and sodium metasilicate and lithium ion salts that can maximize the effect of auxiliary corrosion and snow removal are used. Good.

The metal ion salt used in the environment-friendly snow removal agent with improved frictional force and snow removal effect according to the present invention may be contained in a range of 5 to 40 wt% of the total weight of the wood chip, more preferably, In order to obtain a more effective snow removal effect, the metal ion salt may contain 100 parts by weight of magnesium chloride and 100 parts by weight of magnesium chloride. 1 to 10 parts by weight and 1 to 10 parts by weight of a lithium ion salt may be included. At this time, the lithium ion salt to be used is not particularly limited, but examples include lithium chloride (LiCl), lithium carbonate (Li ₂ CO ₃ ), and lithium oxide (Li ₂ O). The one selected from may be used.

  Therefore, in the case of the environmentally-friendly snow remover with improved frictional force and snow removal effect according to the present invention, the snow removal is performed by the metal ion salt that has been continuously impregnated in the wood chip from the moment it is spread on the snow that has accumulated. Since the effect is shown, it is possible not only to use an appropriate amount of snow removal agent compared to existing snow removal agents, but also to remove snow removal agent every time it snows, so snow removal workability In addition to improving the cost, the economy is improved and it is not necessary to use an excessive amount of metal ion salt, so that secondary environmental pollution can be prevented.

  Furthermore, the environment-friendly snow removal agent according to the present invention further includes microorganisms in the wood chip, so that the microorganisms are released to the outside together with the metal ion salt, thereby acting as a nutrient on the surrounding soil and plants. Not only after the snow has completely melted or when the temperature has risen and the snow removal effect is no longer needed, it remains on the road surface or road by biodegrading the wood chip with microorganisms contained in the wood chip. There is no need for additional work for collecting and disposing of the wood chips.

  In addition, the wood chip flows into the water distribution pipe and the water collecting pipe together with the water made from snow melting, and does not cause clogging, and does not flow into the surrounding farmland or soil and cause secondary environmental pollution. Chips biodegrade and the degradation products flow into the surrounding farmland or soil and act as nutrients, thereby improving soil quality and serving as a compost that can help crops or plants grow. it can.

  Specifically, the microorganisms impregnated in the wood chip are useful microorganisms that are useful for improving plant growth and soil quality, and promoting growth by promoting nutrient absorption in the roots of plants. It is useful for improving plant growth and soil quality by improving biological control against root infectious diseases and suppressing the growth of pathogenic fungi by competitive mechanism against pathogenic fungi and iron. The microorganisms contained in the wood chip that is the skeleton of the snow removal agent according to the present invention can be used without particular limitation as long as it is a microorganism that generally improves soil quality or has a positive effect on plants. Preferably, one or more selected from the group consisting of Bacillus subtilis and lactic acid bacteria may be used.

  Bacillus subtilis is a non-pathogenic bacterium that is widely distributed in nature, especially in air, hay, sewage, and soil. Or an oval spore is formed. In general, the culture medium is also excellent in growth, forms a large grayish white colony, and its periphery is radial. The characteristic of Bacillus subtilis is that it has a spore and is highly resistant, and the microbial cell is a Gram-positive bacterium containing glycogen, and can generate an acid by decomposing many carbohydrates. The Bacillus subtilis grows most actively at 30 to 60 ° C. and grows even at a high temperature of 50 to 56 ° C., but dies if left in steam at 70 ° C. or higher for 15 minutes. Among such Bacillus subtilis, typical Bacillus subtilis bacteria are generally abundantly contained in various fermented foods such as neat soy sauce, natto, miso, kimchi, gochujang, and soy sauce. In the present invention, among the Bacillus subtilis, Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus stearothermophilus, Bacillus stearothermophilus, Bacteria, Bacillus megaterium, Bacillus licheniformis It is preferred to use at least one material et selected.

  Lactic acid bacteria are anaerobic bacteria and are known to be contained in pickles and yogurts in large quantities, producing organic matter-degrading enzymes (protease, cellulase, amylase, etc.), vitamins, amino acids, growth hormones, nucleic acids, etc. It is known to have a function of suppressing the growth of anaerobic harmful microorganisms by reducing the acidity in production. When lactic acid bacteria are activated, plant seed germination and root development are promoted, and organic acids (such as acetic acid and lactic acid) are produced to chelate the cations of insoluble phosphate compounds to form phosphate. It can be solubilized.

  In addition, lactic acid bacteria can suppress pathogenic bacteria by producing bacteriocin, hydrogen peroxide, lactic acid, and antiviral substances. It is mainly used as an inoculum for fermentation compost, and it has a remarkable effect on root growth and initial growth in crops that use a large amount of compost. Examples of lactic acid bacteria used in the present invention include Lactobacillus acidophilus bacteria, Lactobacillus plantarum bacteria, Lactobacillus bulgaricus bacteria, Lactobacillus bulgaricus bacteria, One or more selected from Streptococcus faecalis may be used.

  As described above, Bacillus subtilis or lactic acid bacteria may be used as microorganisms in the snow removal agent according to the present invention, and the Bacillus subtilis and lactic acid bacteria are one of microorganisms that are actively grown or cultured at room temperature, When the snow removal function must be performed continuously, such as when snow is required or when the temperature is low, the activity of Bacillus subtilis or lactic acid bacteria is not active due to the low temperature, which reduces the biodegradability of wood chips. It is possible to exert a snow removal effect that imparts frictional force to the road surface while maintaining the original shape of the wood chip, and continuously melts snow with the metal ion salt impregnated in the wood chip, While the microorganisms are released to the outside, it is useful for improving the quality of the surrounding soil where the snow removal agent is distributed and for growing the plant.

  Furthermore, when the temperature rises and the snow removal effect is no longer necessary, the biodegradability of the wood chips is promoted while the growth of the Bacillus subtilis and lactic acid bacteria is active, and the wood chips remaining on the road surface are decomposed. Therefore, not only the additional work of recovering the snow removal agent is unnecessary, but also the wood chips that are biodegraded act as nutrients on the surrounding soil and plants and are useful for plant growth.

  On the other hand, another embodiment according to the present invention relates to a method for producing an environmentally-friendly snow removal agent impregnated with microorganisms beneficial to soil and crops, preferably an ionic solution in which a metal ion salt is dissolved. A dipping step of dipping the wood chips; a first drying step of drying the wood chips impregnated with the metal ion salt through the dipping step; a spraying step of spraying a microbial culture solution onto the wood chips dried through the first drying step; And a second drying step of drying the wood chips impregnated with the microorganisms through the spraying step, an environment-friendly snow removal agent impregnated with microorganisms beneficial to the soil and crop according to the present invention can be produced. .

  Preferably, as described above, the wood chip may be obtained by crushing by-products generated after processing of the wood, that is, discarded wood, wood, and crushing by forming irregularities on the surface of the wood board. As an example, the wood chip includes a surface treatment step for forming irregularities on the surface of the wooden board; and a crushing step for crushing the wooden board with the irregularities formed on the surface into thin plate-like pieces of wood having a thickness of 1 to 20 mm. Wood chips made in can be used.

  The pattern and form of the unevenness formed on the surface of the wood chip may have various forms and lines as described above, as long as it is an uneven form that can increase the surface area compared to a flat surface. There is no particular limitation.

  As described above, unevenness is formed on the surface of the wood chip and the surface area is improved, so that the sustained release property of the metal ion salt, that is, the sustainability of the snow melting (ice melting) effect and the snow melting time can be controlled. The wider it is, the higher the melting speed of snow that accumulates, and the shorter the biodegradation period by microorganisms.

  This is because the preferred shape and form of the irregularities formed on the surface of the wood chip according to the region and time when the environment-friendly snow removal agent impregnated with beneficial microorganisms in soil and crops according to the present invention is used. Can control the surface area of the wood chip. As an example, in a mountainous region with a lot of snow falling and many roads or slopes, not only can the frictional force be maximized by forming uneven surfaces with a sharp bend on the surface of the wood chip, but the snow can be melted early with a large surface area. Can do. Conversely, if there is not a lot of snow and the snowfall interval or time is long, the wood chip surface is flat, or the irregularities are fine or small, and the irregularities are severely bent. In contrast, when the surface area of the wood chip is small, a relatively long-lasting and repeated snow melting effect can be expected. The above-described example is a description of some examples of various forms of wood chips that serve as the basic skeleton of the environmentally-friendly snow removal agent according to the present invention, and is preferably a microorganism beneficial to the soil or crop of the present invention. The shape of the surface of the wood chip, which is the basic skeleton of the snow removal agent, is appropriately controlled according to the amount of snow to be accumulated, shaded or positive, depending on the region or time when the environment-friendly snow removal agent impregnated with The snow removal agent of the present invention can be produced using the wood chip thus produced.

  Specifically, first, in the dipping stage, the wood chip may be dipped in an ionic solution in which the metal ion salt is dissolved in the wood chip, and the metal ion salt may be impregnated inside the wood chip. The metal ion salt may be impregnated in the void formed in the wood chip through.

  The ionic solution in which the metal ion salt used in the immersion step is dissolved is magnesium chloride, sodium metasilicate, calcium chloride, sodium chloride, and lithium ion. What dissolved at least 1 or more metal ion salt selected from the group which consists of a salt by 1: 0.5-2 mass ratio may be used, Preferably magnesium chloride is 100 weight part, Said chloride What dissolve | melts metal ion salt containing 1 to 10 weight part of sodium metasilicate and 1 to 10 weight part of lithium ion salt on the basis of 100 weight part of magnesium with water by 0.5-2: 1 mass ratio. May be used, more preferably Metal ion salt and water 1: metal ion salt formed by mixing 1 mass ratio may not use the dissolved ionic solution. At this time, the 1: 1 ratio of water and metal ion salt is the most preferable ratio for effectively impregnating the metal ion salt in the wood chip.

  In the immersion step, the wood chip is preferably immersed in the ion solution in which the metal ion salt is dissolved for 40 to 80 minutes in the ion solution in which the metal ion salt is dissolved. If it is removed, the metal ion salt is not sufficiently immersed in the wood chip, it is difficult to expect the desired snow melting effect, and there is no profit due to excess time, which may be inferior in economic efficiency due to the manufacturing process and time.

  The wood chip impregnated with the metal ion salt through the immersion step is primarily dried through the first drying step of drying at 120 to 140 ° C. for 1 to 2 hours, and the surface of the wood chip contains the metal ion salt. Wood chips can be produced.

The wood chip can be impregnated with a microorganism through a spraying step of spraying a microorganism culture solution onto the surface of the wood chip dried through the first drying step, and preferably the microorganism culture solution is sprayed on the wood chip. It can be sprayed uniformly on the surface.
The microorganism culture solution is not particularly limited as long as it is a microorganism culture solution in which microorganisms that biodegrade trees are generally cultured.

  Specifically, the microorganism culture solution may be produced by using a method for producing a known microorganism culture solution after inoculating and cultivating a microorganism capable of biodegrading a tree in a medium. Although not limited, it is preferable to use a microorganism culture solution produced by culturing a microorganism containing at least one selected from the group consisting of Bacillus subtilis and lactic acid bacteria.

  Specifically, the microorganism culture solution can be produced by culturing at 30 to 45 ° C. for 2 to 3 days in a medium containing a nutrient source capable of growing lactic acid bacteria and Bacillus subtilis. In particular, it is preferable not to culture lactic acid bacteria for more than 3 days. This is because the activity of lactic acid bacteria may be weakened due to depletion of nutrients, and lactic acid is accumulated due to the activity of lactic acid bacteria in the medium, reducing the number of live bacteria of lactic acid bacteria Because there are things.

For example, a liquid medium (TSB) using one or more microorganisms selected from the group consisting of Bacillus subtilis or lactic acid bacteria and shaking cultured at 30 to 45 ° C. for 48 to 72 hours, or using MRS Broth medium as purified water After being melted and sterilized at 121 ° C. and 1-2 atm for 10 to 30 minutes, the pressure-sterilized liquid medium is dispensed into a pre-sterilized flask and selected from the group consisting of Bacillus subtilis or lactic acid bacteria 1 A microorganism culture solution can be produced by inoculating a microorganism of more than one species and culturing for 96 hours while stirring at a temperature of 40 to 60 ° C. at a speed of 80 rpm.
At this time, the specific description of Bacillus subtilis and lactic acid bacteria used is as described above, and will be omitted here.

  A wood chip impregnated with microorganisms through the spraying step is packaged after reducing the water content through the second drying step, and an environmentally friendly snow removal agent impregnated with microorganisms beneficial to soil and crops according to the present invention. Can be manufactured.

  Specifically, in the second drying stage, the wood chips impregnated with microorganisms may be dried at 10-30 ° C. for 20-30 hours, and the drying temperature of the second drying stage is less than 10 ° C., Not only does it take a considerable amount of time to dry up to the desired moisture content, but the moisture content is not sufficiently dried and decays during storage and distribution, and mold is generated, reducing the quality of the snow removal agent. When the drying temperature exceeds 30 ° C., the microorganisms impregnated in the wood chip are activated and the biodegradation of the wood chip proceeds, and it is difficult to expect a desired frictional force and snow melting effect as a snow removal agent. .

  Therefore, in the case of an environmentally friendly snow remover impregnated with beneficial microorganisms in the soil or crop according to the present invention, the remaining snow remover is recovered by biodegrading the snow remover with microorganisms at a time when the snow remover is no longer needed. Wood chips made by crushing discarded wood such as forest by-products, woodworking waste wood, and construction site waste wood. The recycle rate of the resources is increased by using the metal ion, and the sustained release effect by the metal ion salt impregnated in the wood chip has the effect of repeatedly and lasting snow melting (snow removal) that is not once in a single distribution. Expected, economical and environmentally friendly.

  Furthermore, wood chips decomposed by microorganisms are highly useful as compost, and they can improve the quality of the soil by supplying nutrients to the surrounding soil and plants where snow removal agents are distributed, and are useful for plant growth. .
