Description

The present invention removes inhabitant bacteria from wood chips obtained by pulverizing wood, decomposes lignin, cellulose, organic matter by enzymes and decomposes the wood chips that have finished the decomposition function while breaking down garbage with microorganisms, wood The present invention relates to garbage-decomposing wood chips using chips.

In recent years, a microorganism treatment method has attracted attention as a method for treating garbage. Many of these microbial treatment methods try to biodegrade garbage with microorganisms by mixing wood chips with microorganisms admixed with garbage, and then stirring the wood chips and garbage at an appropriate temperature. It is.

However, in general, wood chips obtained by pulverizing wood are decomposed into water and carbon dioxide gas in the process of adhering microorganisms, and when the process is repeated for a certain period, the wood chips are crushed. As a result, the honeycomb structure was destroyed and the decomposition action stopped, and the wood chip had to be replaced after a certain period of use.

Wood chips that are no longer needed are reused as compost, but wood chips that have been treated for garbage for a certain period contain a large amount of salt and chemical substances. Had an inviting problem.

In addition, there is a method to remove lignin in the wood chip with chemicals in order to increase the fungal rate of the wood chip. However, lignin is chemically and physically strong, so that the wood can be decomposed by microorganisms, water, and other external evils. Since it plays the role of protecting the honeycomb structure of wood from the conditions, there is a problem that when the lignin is removed from the beginning, the honeycomb structure of the wood chip is destroyed at an early stage, and replacement or composting is accelerated.

In addition, when microorganisms are attached to wood chips and garbage is treated with microorganisms, the microorganisms increase during the treatment process, but the number of microorganisms that originally inhabit wood chips also increases. It is difficult to coexist, and when the decomposition of raw garbage is over a certain period, the decomposition ability is reduced, and there is a problem that early replacement of wood chips or composting is accelerated.

In addition, food waste is a mixture of a wide variety of organic substances, but the long-term treatment of only simple organic substances has been reduced to a few percent of the normal period, and long-term treatment of simple organic substances alone is considered difficult. There is a problem that it is difficult to treat only organic substances for a long time, such as continuing to decompose only the waste from the waste.

The object of the present invention is to reduce the destruction of the honeycomb structure of the wood chip as much as possible, to increase the microbial inhabitant rate and to improve the garbage decomposition ability while decomposing the lignin from the wood chip with the enzyme, and at the same time, the garbage disposal is repeated, The wood chips that are miniaturized and the honeycomb structure is destroyed are decomposed and extinguished by the enzyme. In other words, it is an object of the present invention to provide a wood chip that eliminates the need to replace the wood chip by repeating the decomposition of the garbage and reducing the wood chip itself and only replenishing the wood chip of the present invention. Another object of the present invention is to provide a manufacturing method for manufacturing such wood chips in large quantities. Moreover, it is providing the enzyme wood chip | tip for garbage decomposition | disassembly which uses this wood chip | tip.

The gist of the integrated enzyme wood chip of the present invention is to completely remove microorganisms that inhabit the wood chip by passing high temperature distilled wood acetic acid-containing water.

This structure is a wood chip in which a comprehensive wood-degrading enzyme is contained in a solid wood chip that retains aseptic lignin containing distilled wood acetic acid.

The total enzyme contained in such wood chips is an enzyme that decomposes lignin, fiber, salt, PCB, dioxin, agricultural chemicals, pigments, chlorine compounds, and chemical substances.

In this specification, as a method for obtaining the lignin degradation phenomenon by the general enzyme, the wood chips obtained by pulverizing wood and the chips during the garbage treatment according to the present invention are integrated and immersed in the same amount of acetone. To obtain an acetone extract. Next, after each of the obtained acetone extracts is diluted, lignin is isolated from each diluted solution by liquid chromatography, and the area of the peak amount is obtained. Finally, the lignin peak area of the wood chips during lignin degradation by the enzyme is divided by the lignin peak area of the unused wood chips.

After the garbage refuse wood chip of the present invention passes the high-temperature distilled wood vinegar solution-containing water to make the wood chip aseptic, the remaining distilled wood vinegar solution retains weak acidity even after dehydration. When mixing and stirring the raw garbage decomposing agent of the present invention with raw garbage, the residual distilled wood vinegar solution suppresses the generation of miscellaneous bacteria due to storage, and when used as raw garbage decomposition, the raw garbage is modified to reduce the microorganisms in the raw garbage. Plays a role in promoting proliferation.

In addition, since the garbage decomposing agent of the present invention is configured to contain a general enzyme, when the garbage decomposing wood chip of the present invention is mixed and stirred with the garbage, the garbage is decomposed by the enzyme at the same time. It plays the role of raising the decomposition ability by raising the habitat space of microorganisms that decompose garbage such as decomposition of lignin in the honeycomb structure. The wood chips are dispersed in a range of 0.2 to 25 mm. The smaller the wood chip, the higher the surface area of contact with garbage, and the higher the decomposition rate and lignin decomposition rate. Wood chips themselves are decomposed and disappeared by degrading enzymes.

In addition, the general enzyme works on garbage and decomposes it, but it activates microorganisms as another effect. The garbage is decomposed and extinguished by the synergistic effect of the decomposing power of the general enzyme and the degrading power of microorganisms.

In addition, total enzymes detoxify the toxicity of minerals by combining with trace elements in garbage, especially metals and minerals called heavy metals, while the function of the enzyme itself increases several thousand times to several tens of thousands of times due to the binding. To do. Therefore, the garbage processing speed is increased, and a large amount of garbage can be processed in a short time.

In addition, the enzyme as the gist of the biodegradable agent of the present invention includes alcohol dehydrogenase, lactate dehydrogenase, glucose 6-phosphate dehydrogenase, aldehyde dehydrogenase, L. aspartate, Beta-semialdehyde / NADP oxidectase, glutamate dehydrogenase, aspartate semialdehyde / dehydrogenase, NADPH ₂ cyclochrome C-reactase, glutathione dehydrogenase, trehalose phosphate synthetase, polyphosphae Kinase, ethanolamine phosphatidyl cytidyltransferase (CTP)
Trehalose phosphatase, metalthiophosphoglycerate phosphatase, inulase, β-mannositase, uridine nucleositase, cytosine diaminase, methylcysteine synthetase, aspartate synthetase, succinate dehydrogenase, aconitinate hydrogenase, fumarate hydro Genase, maleate dehydrogenase, citrate synthetase, isocitrate dehydrogenase, LSNADP oxidase, monoamine oxidase, histamine, pyruvate decarboxylase, ATPase, nucleotide pyrophosphatase, endopolyphosphatase, ATP phosphatase Comprehensive including fohydrolase, orotidine 5-phosphate decarboxylase, cellulase Is the elementary.

In addition, food waste is a mixture of a wide variety of organic substances, but the long-term treatment of only organic substances such as okara and meat alone has been reduced to a few percent of the normal decomposition period, and only organic substances are decomposed. Although long-term treatment has been considered difficult, the biodegradable agent of the present invention is in a sterile state, so there is no generation of microorganisms that hinder the activation of microorganisms generated from simple organic substances, and enzymes decompose the simple organic parts. While promoting the activation of microorganisms, it helps increase the number of microorganisms. Therefore, the garbage decomposing agent of the present invention performs a long-term decomposition treatment of only a single organic substance, which has been considered difficult, and is decomposed and extinguished by a fiber-degrading enzyme from a very small wood chip whose honeycomb structure has been destroyed and has no decomposition ability. Follow the process.

With this configuration, the garbage decomposing agent of the present invention quickly decomposes garbage with synthetic enzymes, decomposes salts, heavy metals, and chemical substances, and incubates microorganisms while decomposing lignin in the wood of the garbage decomposing agent. While expanding the space, the microorganisms are increased and the garbage is decomposed together with the enzyme. Also, the enzyme linked to the heavy metal is increased, and the decomposition of the garbage garbage from the smallest of the wood chips is broken down with the garbage by the fiber-degrading enzyme. Can be made.

The gist of the present invention is that a wood chip obtained by pulverizing wood is put in a water-containing container and distilled water containing 90 to 98 degrees Celsius of distilled wood acetic acid is allowed to pass through without taking lignin in the wood chip. A method for producing distilled wood acetic acid-containing sterile wood chips comprising a step of sterilizing wood chips.

The gist of the present invention is that a wood chip obtained by pulverizing wood is housed in a water-containing container, and the container for housing the wood chip is 90 to 98 degrees Celsius distilled wood acetic acid aqueous solution. The wood chip remains aseptically 5 to 10% of the distilled wood acetic acid aqueous solution by the step of obtaining sterile wood chips while retaining the lignin and the step of dewatering the distilled wood acetic acid aqueous solution from the wood chips with a centrifugal dehydrator It is in the process of producing acidic wood chips.

With this structure, a distilled wood acetic acid-containing aseptic wood chip having a strong honeycomb structure can be obtained without removing lignin that prevents destruction of the honeycomb structure of the wood chip from a large amount of wood chips obtained by pulverizing wood.

Further, the gist of the aseptic wood chip manufacturing apparatus of the present invention is that the outside of the tank is the water absorption side, the center of the tank is the ejection side, and a radial distilled wood acetic acid aqueous solution is placed in a three-dimensional form from the center. This is a manufacturing method in which a short-distance aqueous solution passes in a radial direction from a central jetting tower while the inside of the wood chip container is horizontal.

With this structure, a weakly acidic aseptic wood chip can be produced by passing the distilled wood acetic acid aqueous solution evenly and uniformly.

The suction wall surface outside the tank and the wall surface of the central ejection tower having such a structure are configured such that holes for water absorption and ejection water are evenly arranged.

Since the integrated enzyme aseptic wood chip of the present invention does not remove lignin, when it is mixed with garbage as a garbage decomposing agent while firmly holding the honeycomb structure of the wood chip, it decomposes the garbage with the included comprehensive enzyme. At the same time, it promotes the promotion of microorganisms generated from garbage, and the microorganisms decompose and eliminate garbage. The lignin-degrading enzyme works to break down the lignin in the wood while expanding the habitat of microorganisms, increasing the number of microorganisms and increasing the ability to decompose microorganisms. By continuing to decompose garbage, the wood chips themselves are subdivided, and the ultra-finely divided ultra-small wood chips destroy the honeycomb structure and become in a compost state without the ability to decompose garbage, but the fiber-degrading enzyme decomposes This is a garbage-decomposing wood chip that decomposes and extinguishes the minimal wood chips that have lost their capacity, and also disassembles and eliminates the minimal wood chips that are no longer needed along with the garbage. Therefore, by using the wood chip for decomposing garbage containing the integrated enzyme distilled wood vinegar solution of the present invention as a garbage treatment agent, it disappears from the extremely small wood chips that have stopped functioning with the garbage, so there is a risk of soil contamination due to recycling. Can be avoided. Moreover, since only a single item can continue to disappear, there is an effect that it can be processed only from the tofu industry's okara processing or the ham industry's meat.

In addition, by processing wood chips using the aseptic wood chip manufacturing apparatus of the present invention, it is possible to effectively perform aseptic processing while firmly holding the honeycomb structure of the wood, so that a large amount of sterile wood chips is manufactured. can do.

The manufacturing method of the synthetic enzyme aseptic wood chip concerning this invention is demonstrated in detail below.

The aseptic wood chip according to the present invention can be obtained by passing an acidic or alkaline acid chemical such as an aqueous caustic soda solution or an aqueous hydrogen peroxide solution, but it is particularly desirable to obtain it by a method for producing an aseptic wood chip as described below. .

That is, the method for producing aseptic wood chips of the present invention includes a step of passing through a wood chip with a high-temperature aqueous solution of distilled wood vinegar, a step of dehydrating wood chips containing the high-temperature aqueous solution of distilled wood vinegar, and a step including a general enzyme. The

The wood chip used in the present invention may be obtained from any wood as long as it has a sufficient honeycomb structure, and may be thinned wood such as coniferous broad-leaved trees. The length of the wood chip is preferably 0.2% to 3 mm and 50% to 3 to 25 mm. When mixing with garbage, the smaller the chip, the larger the contact area, and the larger the chip, the smaller the contact area, but the smaller chip has a faster ability to decompose, but the destruction of the honeycomb structure is faster and the entire structure becomes smaller by continuing to decompose. Therefore, the above chip ratio is preferable in view of the decomposition power and the durability of the chip.

In the present invention, alkaline or acidic chemicals such as caustic soda and hydrogen peroxide can be easily put into a sterilized state for sterilization, but at the same time, lignin, which is a substance for maintaining the honeycomb structure of wood, is removed. As a result, the durability of the wood chip is greatly impaired. In order to avoid the above disadvantages, sterilization with distilled wood vinegar-containing water can provide a sterile wood chip that retains a strong honeycomb structure without causing the lignin that holds the wood honeycomb structure to flow away.

The wood chip of the present invention is sterilized with distilled wood vinegar-containing water to dehydrate the distilled wood vinegar-containing water by post-treatment, but a small amount of distilled wood vinegar remains on the whole wood chip, and the wood chip is weakly acidic. Will be held. When the garbage decomposing agent of the present invention is mixed and stirred with garbage, the residual distilled wood vinegar solution serves to improve the garbage and promote the growth of microorganisms in the garbage.

In the production method of the present invention, wood chips sterilized with water containing distilled wood vinegar can be made from chemical substances and water, but by using distilled wood vinegar containing water, wood can be maintained without holding the honeycomb structure and removing lignin. Distilled wood vinegar liquid permeates the entire chip, and a good garbage-decomposed wood chip such as the degree of completion of sterilization, antiseptic measures during storage, the growth of microorganisms in garbage, and the deodorizing effect can be obtained. In addition, when sterilized with alkaline or acidic chemicals, the chemicals must be removed by a water washing process. When distilled wood vinegar is included in this subsequent process, distilled wood vinegar is only contained on the surface of the wood chips. The inside of the wood chip will corrode. Therefore, the process of passing the distilled pyroligneous water of the present invention and dehydrating it as it is is the best method.

In the production method of the present invention, the content of distilled wood vinegar in wood chips sterilized with water containing distilled wood vinegar is 0.2 to 0.8 weight ratio, and the distillation is 90 to 98 degrees Celsius within 20 minutes to 2 hours. Good passage of water containing pyroligneous acid solution. The ratio of distilled wood vinegar solution containing distilled wood vinegar to pass through wood chips is 0.2 to 0.8% by weight, but at 0.8% or more, the pH becomes 6.0 or less and the acidity becomes strong and the activity of microorganisms. If it becomes 0.2 or less, it becomes inclined to alkali and causes decay of wood chips.

In the present invention, when the wood chips pass through the distilled wood vinegar-containing water in the tank, the wood chips are placed in a 0.05 to 0.2 mesh container and fixed so that the chips do not move. In that case, since it can pass uniformly, it is preferable to make it a pillow-shaped container. In the case of a rectangular container, the corners overlap each other, making it difficult for water containing distilled wood vinegar to completely pass therethrough. In addition, when the distilled wood vinegar solution-containing water of the container passes through, it becomes difficult for the distilled wood vinegar solution-containing water to completely pass through even in the case of a plurality of layers. Therefore, in order for water containing distilled pyroligneous acid solution to pass through completely, the container should be in the form of a pillow that does not overlap. In addition, the present invention is not limited to the above, and it may be a hard container configured with an outer surface of 0.05 to 0.2 mesh.

In the present invention, the distilled wood vinegar solution-containing water tank is a vertically long tank that contains distilled wood vinegar solution-containing water jetted from the center so that it passes through the tank outer suction wall in a horizontal and constant direction to contain wood chips. Water containing distilled pyroligneous acid solution can completely pass through the container.

In the apparatus tank 10 of the present invention, the distilled wood vinegar-containing water jetted from the uniformly arranged central punch holes 12 applied to the central jet tower 11 moves horizontally from the central jet tower 11 through the wood chip storage bag 9 to the outside of the tank. The distilled wood vinegar-containing water sucked and sucked into the outer wall punch holes 14 uniformly arranged on the thirteen water-absorbing walls 15 descends the tank outer wall space and is sucked into the pump 17 installed at the tank bottom 23 and returns to the central jet tower 11. This process is repeated repeatedly. When the pump 17 sucks up the steam, the steam heated in the boiler 19 becomes hot due to the steam jetted from the steam outlet 20 installed in the lower part of the pump 17. The temperature sensor 21 measures the temperature and controls the temperature control valve 18. In the aseptic treatment, water is introduced from the water tap 22, and then distilled wood vinegar is added and treated in the above process. After the treatment, the water is drained from the drain pipe 16. During processing, the tank 24 is covered with a lid 24 for processing. By carrying out the method for producing aseptic wood chips of the present invention in such an apparatus tank 10, it is possible to obtain aseptic wood chips containing a distilled wood vinegar solution that retains a strong honeycomb structure without removing lignin.

In the process of making the aseptic wood chip of the present invention, when chemical substances such as caustic soda and hydrogen peroxide are used, a water washing process for extracting the chemical substances must be included, but in the manufacturing process of the present invention, water containing distilled wood vinegar is contained. This method has the advantage that the washing process can be omitted and the antiseptic microbial activity treatment can be performed at the same time, and the production cost can be reduced compared with the use of chemical substances.

When chemical substances such as caustic soda and hydrogen peroxide are used in the present invention, the lignin in the honeycomb structure of the wood chips will be eluted, and the habitat space of the microorganisms will be expanded and the ability to decompose garbage will increase, but on the other hand the processing period of the wood chips Will be shortened. The removal of lignin to about 85% by chemical treatment can be used as a garbage decomposing agent. However, the removal of lignin exceeding 85% will cause the product to fall to about 20% compared to the period when the decomposition period is not removed. turn into. In addition, the treatment effect when the enzyme provided by the present invention is included using wood chips using chemical substances, the destruction of the honeycomb structure is accelerated by removing lignin, and the total enzyme provided by the present invention The processing capacity of the fiber-degrading enzyme is uncertain, resulting in faster replacement of wood chips or composting. Therefore, considering the balance with the total enzyme treatment, the wood chip holding the strong honeycomb structure manufactured by the method of passing only the distilled wood vinegar-containing water of the present invention that does not remove lignin is economically minimal and the end of life Since wood chips are decomposed and extinguished by enzymes, the wood chips of the present invention produce the best results both economically and after-treatment considering the need for replacement of wood chips and the need for processing after composting. It will be.

The enzyme provided in the garbage decomposition aid of the present invention is composed of comprehensive enzymes that comprehensively decompose, such as lignin-degrading enzymes, fiber-degrading enzymes, chemical-degrading enzymes, fats, proteins, starches, salts, and PCBs. Enzymes which are the gist of the garbage decomposition aid of the present invention include alcohol dehydrogenase, lactate dehydrogenase, glucose 6-phosphate dehydrogenase, aldehyde dehydrogenase, L. aspartate beta Semialdehyde / NADP oxidectase, glutamate dehydrogenase, aspartate semialdehyde / dehydrogenase, NADPH ₂ cytochrome C / reactase, glutathione dehydrogenase, trehalose phosphate synthetase, polyphosphae kinase , Ethanolamine phosphae cytidyltransferase (CTP) trehalose phosphatase, metalthio phosphoglycerate phosphatase, inulase, β-mannositase, uri Nucleositase, cytosine diaminase, methylcysteine synthetase, aspartate synthetase, succinate dehydrogenase, aconitate hydrogenase, fumarate hydrogenase, maleate dehydrogenase, citrate synthetase, isocitrate dehydrogenase It is a comprehensive enzyme including RNase, LSNADP oxidase, monoamine oxidase, histaminase, pyruvate decarboxylase, ATPase, nucleotide pyrophosphatase, endopolyphosphatase, ATP phosphohydrolase, orotidine 5-phosphate decarboxylase, cellulase . The action of the general enzyme promotes the generation and activation of microorganisms by contacting and stirring with garbage, decomposing fat, protein, starch, salt, PCB, etc. and decomposing lignin in the wood chip, along with the growth of microorganisms The habitat is expanded. At the same time, by repeatedly decomposing the garbage, the wood chips are subdivided, and when the honeycomb structure of the minimized wood chips is destroyed, microorganisms cannot live and compost, and the fiber material decomposes the fiber material. It is an enzyme that aids in the decomposition of garbage.

The enzyme of the present invention is preferably blended in an amount of 0.1 to 0.8% by weight, more preferably 0.2 to 0.5% by weight, based on sterile wood chips. When the blending ratio is less than 0.1% by weight, microorganisms are difficult to activate and it takes a long time to decompose garbage, and the ability to decompose lignin is reduced, and the expansion of the habitat of microorganisms is slowed, resulting in decomposition of garbage. Processing capacity falls. In addition, the ability to break down the fibers is reduced, and the ability to disappear the wood chips is reduced, and the wood chips are replaced or composted. On the other hand, when it exceeds 0.8% by weight, the decomposition rate of lignin, the decomposition of small wood chips and the corrosion of garbage are accelerated, the decomposition balance is lost, and the decomposition ability of garbage is reduced. Therefore, 0.2 to 0.5% by weight of the total enzyme is the best.

The aseptic wood chip of the present invention decomposes garbage with a structure in which a comprehensive enzyme is contained in a sterile wood chip containing a distilled wood vinegar solution having a strong honeycomb structure without removing lignin for maintaining the honeycomb structure of the wood chip. In the process, the lignin of the wood chip is decomposed to expand the habitat space of microorganisms and increase the ability to decompose garbage. By repeatedly decomposing the garbage, the wood chip is subdivided and becomes a minimum and the function of decomposition Follow the process of degrading by the fiber-degrading enzyme from the one that can no longer fulfill. For this reason, the garbage-decomposing synthetic enzyme wood chip of the present invention is mixed with and mixed with raw garbage under a constant temperature, so that the garbage-decomposing microorganisms grow in large quantities through the wood chip and the enzyme. By the mutual action of microorganisms, it becomes possible to completely decompose garbage into water and carbon dioxide. Then, it will dissipate from the small timber chip that has finished its role, breaking down into water and carbon dioxide. As a result, unnecessary wood chips are also decomposed while disassembling the garbage, so there is no need to replace the wood chips or use compost, and the wood chips will decrease while decomposing the garbage after a certain period of time. Only maintenance of wood chips is required. Therefore, by using the general enzyme aseptic wood chip of the present invention, economical and simple garbage decomposition treatment can be performed.

Example 1

(Manufacture of aseptic wood chips)
Wood chips having an outer shape of 0.2 to 25 mm are obtained from wood such as conifers and broad-leaved trees, and at this time, wood that is in the form of wood, whether raw or driftwood. When manufacturing with a chip manufacturing machine, the finer the setting, the more subdivided Kishiro chips are set at the same time, so the preferred composition of wood chip diameter is 0.2 to 3 mm 50% and 3 to 25 mm 50% In the case of setting, the setting with a wood chip manufacturing machine manufactured by Kubota was performed with a setting of 10 mm. Next, the wood chip is placed in a 0.1-0.05 mm mesh hemp or synthetic resin bag (9 in FIG. 2). The shape of the bag at this time is preferably a pillow shape. The apparatus tank 10 having the next volume of 1000 L is piled up from the bottom plate portion. Next, water is poured from the water supply port 22 to the full tank. Next, 0.5% by weight of distilled wood vinegar is added. Next, the device tank 10 is covered with a lid 24 and the pump 17 is started. At the same time, high-temperature steam is sent from the boiler 19 from the steam outlet 20. While looking at the water temperature gauge 21, circulate the wood chip at 97 degrees Celsius for 1 hour and 30 minutes. At this time, if it is 20 minutes or less, it will not be completely aseptic, and if it is 2 hours or more, lignin will dissolve and weaken the honeycomb structure of wood chips.

Next, all the water containing distilled wood vinegar solution is drained from the drain 16 from the apparatus tank 10, and then the wood chip containing bag 9 containing the water containing distilled wood vinegar solution is dehydrated for 5 minutes with a centrifugal dehydrator. The distilled wood vinegar-containing water remaining in the wood chips is 5 to 10% by weight, and a sterile wood chip containing distilled wood vinegar is obtained. Next, the wood chip is taken out from the storage bag 9, and 0.5% by weight of the enzyme is added to the wood chip 100 with a stirring mixer and stirred for 5 minutes to decompose garbage with a strong honeycomb structure that does not remove lignin.

(Example 2)

(Manufacture of lignin removal chip)
Wood chips having an outer shape of 0.2 to 25 mm are obtained from wood such as conifers and broad-leaved trees, and at this time, wood that is in the form of wood, whether raw or driftwood. When manufacturing with a chip manufacturing machine, the smaller the setting is, the smaller the sub-set wood cost chip will appear at the same time, so the preferred composition of wood chip diameter is 0.2 to 3 mm 50% and 3 to 25 mm 50% In the case of setting, the setting with a wood chip manufacturing machine manufactured by Kubota was performed with a setting of 10 mm. Next, the wood chip is placed in a 0.1-0.05 mm mesh hemp or synthetic resin bag (9 in FIG. 2). The shape of the bag at this time is preferably a pillow shape. Next, it piles up and puts into the apparatus tank 10 of a capacity | capacitance 1000L from a baseplate part. Next, water is poured from the water supply port 22 to the full tank. Next, 10 kg of caustic soda (sodium hydroxide) 20% solution was added. Next, a lid 24 is placed on the tank 10 and the pump 17 is started. At the same time, high-heat steam is sent out from the boiler 19 through the steam outlet 20. While looking at the water temperature gauge 21, circulate in the wood chip at 97 degrees Celsius for 20 minutes. Next, the caustic soda-containing water is entirely drained from the drain 10 through the tank 10. Next, water is charged from the water supply port 22 to a full tank, and 20 kg of hydrogen peroxide is added. Next, a lid 24 is placed on the tank 10 and the pump 17 is started. At the same time, high-heat steam is sent out from the boiler 19 through the steam outlet 20. While looking at the water temperature gauge 21, circulate in the wood chip at 97 degrees Celsius for 60 minutes. Next, all of the hydrogen peroxide-containing water is drained from the drainage port 16 from the apparatus tank 10, and then the water is filled from the feed port 22 to the full tank and circulated in the tank 10 for 15 minutes to drain. Repeat to obtain lignin wood removal chips. At this time, wood chips having a lignin removal rate of 50% were obtained. Next, the wood chip was taken out from the storage bag 9, and 0.4% by weight of the enzyme was added to the wood chip with a stirring mixer and stirred for 5 minutes to obtain a wood chip for garbage decomposition from which 50% of the lignin was removed. . In addition, since the enzyme contained here is a wood chip that has decomposed lignin, it is not a lignin-degrading enzyme of the present invention, but is a commonly used enzyme such as oil, protein, starch, lipase, amylase, and protease. The same weight ratio of enzyme was included.

Then, when the wood chip of the present invention that does not remove lignin and a 30% lignin-removed wood chip were compared on a trial basis, digestion ability began to decline after 120 days of the 50% lignin-removed chip. The total capacity, including, began to increase, and the tendency to crease began. After 180 days, it was no longer disassembled and wood chips had to be replaced. The wood chip of the present invention that does not remove lignin started to decrease in wood chip around 120 days, and the total amount of wood chips decreased to 93% around the 180th day. Therefore, the wood chip of this invention that does not remove lignin is supplemented with 7%. did. As a result, it was found that the chip from which lignin was removed with a chemical substance was inferior to the aseptic wood chip of the present invention. Therefore, when the chip from which lignin has been removed is repeatedly decomposed for a certain period, the wood chip has to be replaced, and the wood chip of the present invention can be replaced without replacing the chip. The test at this time is a result of continuously feeding 1 kg of similar garbage every day to the wood chip 17L with a garbage disposal machine (BM-A40, manufactured by Towa Sangyo Co., Ltd.).

(Example 3)

(Comparison of single item disassembly)
The wood chip for garbage decomposition of the present invention was verified with respect to decomposition of only a single substance. Chips to be compared are generally used for wood chips of 0.2 to 25 mm in outer diameter, which are generally used, from hardwood and other wood, and in that state, ie, wood chips that are not sterilized. The waste decomposition chip containing 0.4% by weight of the enzyme, oil, protein, lipase, amylase, and protease, which decomposes starch, in the same weight ratio, and the aseptic wood chip for garbage decomposition of the present invention A single product disassembly test was conducted. The test machine at this time was a garbage disposal (manufactured by Towa Sangyo Co., Ltd., BM-A40 Co., Ltd.). As a result, the total amount of wood chips that were not sterilized increased from the 16th day, including the chips, and the chips had to be replaced on the 24th day. On the other hand, the aseptic wood chip of the present invention continues to decompose okara even after the 24th day and after 50 days, and the amount of okara fibers is also decomposed by the fiber-degrading enzyme, increasing the total amount. No results. Therefore, the long-term treatment only for simple organic substances such as okara and meat is considered to be difficult for long-term treatment only for simple organic substances because the period of decomposition falls to the usual several percent in conventional garbage processing. Since the biodegradable agent of garbage is in a sterilized state, it eliminates the factors that hinder the activation of microorganisms generated from simple organic substances, and promotes the activation of microorganisms generated from simple organic substances of microorganisms while the enzyme decomposes the simple organic parts. Help increase. Therefore, the garbage decomposing agent of the present invention performs a long-term decomposition treatment of only a single organic substance that has been regarded as difficult, and a process in which the honeycomb structure is destroyed and decomposed and extinguished by a fiber-degrading enzyme from a very small wood chip that has lost its decomposition ability We were able to verify the following.

The complete recycling of the garbage recycling method is enforced from 2006 from the viewpoint of preventing global warming for the wood chip for garbage decomposition containing the integrated enzyme distilled wood vinegar solution of the present invention. Along with that, companies that discharge 100 tons or more of garbage per year must eliminate 20% of them by their own efforts. Therefore, companies that comply with this law in the industrial field usually use a garbage disposal machine with a reduced weight. However, the weight loss method requires a huge amount of heat energy to reduce the drying temperature at high temperatures such as electricity, gas, and oil. From the viewpoint of preventing global warming, a considerable amount of carbon dioxide must be discharged, which is a conflicting result. However, in the bio-type treatment generated by natural ecosystems, the same waste treatment can be emitted by a few percent of carbon dioxide compared to the weight reduction method. Therefore, from the viewpoint of preventing global warming, the bio system is the ideal form for garbage disposal.

In the bio-type treatment, the treatment substrate is forced to be replaced after a certain period. In addition, organic wood that is no longer necessary can be recycled as compost, but depending on the treated material, there is a risk of causing secondary pollution such as salt damage or soil contamination by chemical substances.

Unlike the conventional recycled wood chips, the integrated enzymatic distilled wood vinegar solution-containing wood chips of the present invention do not initially remove the lignin that firmly builds the honeycomb structure that functions the wood chips, As the generation of microorganisms increases, the lignin is decomposed by enzymes to expand the living space of microorganisms, increase the processing capacity, and the wood chip fragmentation begins as the decomposition is repeated, and the honeycomb structure is destroyed due to minimization It is a function that decomposes and disappears by enzymes.

Therefore, industrially using the wood chip for decomposing garbage containing the integrated enzyme distilled wood vinegar solution of the present invention as a garbage treatment agent, the wood chips that have stopped functioning with the garbage will also disappear. You can avoid danger. In addition, from the viewpoint of preventing global warming, it is possible to process biodegradation of a single item from the viewpoint of preventing global warming, such as tofu processing from the tofu industry or processing from only the meat from the ham industry, which was said to be unable to continue disappearing only the single item. There are industrial uses.
