Description

Structure of the garbage disposal machine

This creation is about a method of treating raw garbage using microorganisms belonging to the genus Bacillus.

In the past, raw waste (also known as kitchen waste, food waste, daily food waste, or organic waste) can be divided into "composting method", "carbonization method", "destruction method", etc. according to their disposal methods Type; among them, what has become the mainstream today is a type called bio (bio) treatment type. This method is a method that uses microorganisms to decompose raw waste into water and carbon dioxide, which can be divided into "compost type" and "extinction type" according to their engineering. "Compost" is a method that uses compost as a product and discharges it. The "extinction type" is a method of discharging raw garbage into water and CO _{2 at the} end. The "compost" type garbage disposal system must drain the water of the garbage; because the moisture of the garbage can not be decomposed for a long time, the water is evaporated and used for fermentation. Therefore, high power consumption and fuel costs are required. For example, the processing temperature described in Non-Patent Document 1 is 40°C to 72°C. Therefore, the microorganisms used are also aerobic microorganisms with high heat resistance and high-temperature microorganisms. On the other hand, in the conventional destruction type garbage disposal machine, for example, as described in Patent Document 1, it is of course necessary to maintain the operating temperature at a high temperature depending on the type of microorganism used. In addition, in order to prevent clogging of the screen, for example, a device with a bubbling mechanism as shown in Patent Document 2 may be used; for example, it may be formed by deforming a stirring wing as shown in Patent Document 3.

<Problems to be solved by creation>

However, the "compost" type of garbage disposal machine is a method of fermenting garbage into compost. Since the device is heated to around 60°C and used, it requires high power consumption and fuel costs, and expensive operation. cost. In addition, in each treatment of raw garbage, compost must be taken out, and the residue must be cleaned up. In addition, due to the fermentation of raw garbage due to high temperature, there are problems such as the occurrence of significant odor and the limitation of the installation place.

In addition, in the conventional "extinction type" garbage disposal machine and garbage disposal method, the treatment capacity of microorganisms for disposing of garbage is also low, and it is not possible to dispose of garbage in a short time. In addition, even if it is assumed that the garbage can be processed in a short time, during the decomposition of the garbage, it will also occur: the garbage blocks the screen, the stirring blade is damaged, and the solid-phase treatment tank is submerged in water, etc., so that it does not Able to continue to use stably. Patent Document 2 describes a device with a foaming mechanism attached; although there are also those that deform the stirring blade as shown in Patent Document 3, the structure of the device is complicated, and the structure of the stirring blade It becomes complicated, so when foreign substances such as metal spoons are mixed in, the stirring blade and the foreign substances will scratch the screen and cause the screen to be damaged.

This creation was completed in order to solve the above-mentioned problems, and the object is to provide a disposal method of an eradicating garbage generator for long-term and stable use. The "raw garbage" in this creation is sometimes called food waste, food waste, daily food waste, or organic waste. <means to solve the problem>

In order to solve the above-mentioned problems, the characteristic of this creation is that the raw waste decomposition microorganisms in the raw waste treatment method include IMI-1 (bacillus subtilis) deposited with the deposit number: NITE P-02373, and the deposit number: NITE P －At least one of IMI-2 (bacillus amyloliquefaciens) deposited by 02374, or IMI-3 (bacillus subtilis subsp. linaquosorum) deposited by NITE P－023745, and mixed with raw garbage.

In addition, another special feature lies in that two or three kinds of the three kinds of microorganisms are mixed and used as a microorganism that decomposes raw garbage.

Still another feature is that a microbial carrier that supports microorganisms for decomposing microorganisms on a porous ceramic and a buffer material made of resin is mixed with the garbage.

In addition, another feature is that the shape of the porous ceramic is formed into a spherical shape with a diameter of 7 mm to 10 mm, and the shape of the resin-made cushioning material is formed into a cylindrical shape with an inner diameter of 10 mm and a length of 10 mm to 12 mm.

In addition, another feature is that in a raw garbage treatment apparatus provided with a solid-phase treatment tank that can be loaded with raw garbage and treated, and a stirring means holding a stirring blade for stirring raw garbage, the The bottom of the solid-phase treatment tank has a mesh with a hole diameter of 1.5 mm to 2.0 mm; the distance between the front end of the stirring blade and the screen is 10 mm to 30 mm; a rubber portion is provided at the front end of the stirring blade. During the operation of the stirring blade, the rubber portion is in contact with the screen. ＜Creation effect＞

As mentioned above, according to this creation, a biological preparation blended with the above three types of microorganisms is proposed by using a porous spherical ceramic (support A) and a cylindrical shape (inner diameter φ10mm×length 10) ～12mm) The resin-made support B is used as a cushioning material, and can dispose of raw garbage in a short time, safely and reliably.

In addition, the porous spherical ceramic system has the effect of multiplying microorganisms on the surface and the porous part, and has the ability to crush the raw garbage by its own weight, and cut the fiber that is difficult to decompose. effect. The cylindrical resin support B has the effect of wear of the device due to the pressure of the porous spherical ceramic dispersed in the bottom of the device, and the irregularities on the surface of the cylindrical surface become microorganisms Carrying body. Also, at the same time, the space in the raw garbage is ensured by the cylindrical space, and becomes the oxygen supplier required to decompose the raw garbage, and when the cylindrical resin support B and the porous ball When the shaped ceramics (loaded body A) are put into the disposal of raw garbage, it also has the effect of shortening the decomposition time of the raw garbage.

In addition, a method for treating raw garbage is proposed by using a method in which the hole diameter of the screen at the bottom of the solid-phase treatment tank is 1.5 mm to 2.0 mm in diameter, and the interval between the stirring blades is 10 mm to 30 mm. 1. The structure of the rubber blade is attached to the front end of the stirring blade, so there is no damage and trouble of the device, so the raw garbage can be disposed of for a long time and safely. By forming the gap between the front end of the stirring blade and the bottom screen of the solid-phase treatment tank to 10 mm to 30 mm, sufficient clearance can be ensured, even if foreign substances such as metal spoons are mixed in, the stirring blade and foreign substances can be prevented The problem of scratching the screen together and causing the screen to break.

However, when the distance between the front end of the stirring blade and the bottom screen of the solid-phase processing tank is set to 10 mm to 30 mm, it is impossible to stir the raw garbage near the bottom of the solid-phase processing tank, so there will be: The capacity of garbage is reduced and raw garbage blocks the screen, and the solid-phase treatment tank is submerged in water. Therefore, by providing a rubber part at the tip of the stirring blade and fixing the length in contact with the bottom screen part, even if foreign substances such as metal spoons are mixed, the elastic effect of the rubber can prevent the screen of the solid-phase treatment tank Troubles like scratches and damage.

In addition, since the rubber part is in absolute contact with the mesh part at the bottom of the solid-phase treatment tank when the stirring blade rotates, it is possible to prevent clogging of the mesh caused by raw garbage in advance. In this way, the optimal design of the stirring blade and the effect of the rubber at the front end make it possible to continue to use the garbage disposal machine for a long time without trouble. The length of the rubber part is 8cm to 10cm from the axial direction of the stirring blade to the screen plate, and the width is 9cm to 11cm (device with a processing capacity of 250kg/day), 19cm (processing capacity is 5000kg/day Device), the width is enlarged in proportion to the capacity of the device. It is installed in a rectangular shape with a thickness of 1 cm to 1.5 cm (apparatus with 250 processing capacity of 250 kg/day).

In addition, the microorganism used in this creation is a medium-temperature microorganism. Since the optimal use temperature is 15°C to 35°C, it does not need to be used in compost-type and the current eradication-type garbage disposal machines. By heating the used aerobic microorganisms or high-temperature microorganisms, the decomposition of raw garbage can be carried out, so the production and maintenance costs of the device are cheap.

According to the raw garbage treatment device of this creation, under standard conditions, the processing time with rice or pasta is 2 hours to 5 hours, the processing time with vegetables or fruits is 8 hours to 24 hours, the compost type, and the current extinction type In comparison with the garbage disposal machine, the disposal time of the garbage produced using the microorganism of the present invention can be rapidly processed in a short time. Although it may take more than 20 hours to process the onion skin with a lot of fiber and bamboo skin, etc., as long as it is a food that can be eaten by humans, almost all can be decomposed.

In the regular operation, when the drainage of the raw garbage treatment device of this creation is taken and measured, the value of hydrogen ion concentration is 5.8 (25°C), and the value of biochemical oxygen demand (BOD) is 510 mg/L. This value is 35,000g/L of miso soup in a cup of household drainage and 3000g/L of rice washing water, so it is estimated that almost all raw garbage is eliminated. As described above, it can be confirmed that the original garbage disposal method using microorganisms created by the author can rapidly process raw garbage in a short time.

Hereinafter, the form of one embodiment of the present creation will be described using the drawings. Figure 1 is a cross-sectional view of the composition of the raw garbage treatment method based on this creation. FIG. 2 is a partial diagram showing an example of the configuration of the stirring section of the raw garbage treatment method illustrated in FIG. 1. Fig. 3 is a diagram illustrating the appearance of a porous spherical ceramic. Fig. 4 is an explanatory diagram of the appearance of a cylindrical buffer material.

For example, to give an example of an explanation device, put in the bottom part 9 of the solid-phase treatment tank of the garbage disposal machine of FIG. 1: deposit number: NITE P-02373 deposited IMI-1 (bacillus subtilis), or deposit number: NITE P -02374 deposited IMI-2 (bacillus amyloliquefaciens), or deposit number: NITE P-02375 deposited IMI-3 (bacillus subtilis subsp. linaquosorum) any one of the microorganisms that decompose raw garbage, or a combination thereof 500g of the prepared biological agent. On top of it, put 40kg of raw garbage to be treated. Furthermore, 20 kg of porous ceramics 11 and 125 L of resin-made cushioning material 12 were put on it. The resin-made buffer material 12 is not limited to polypropylene, and polyethylene, polystyrene, polyvinyl chloride, polyethylene, ABS resin, and PET can also be used.

Although the method of adding microorganisms to raw garbage is not particularly limited; however, in practice, it is easy to add raw garbage to it by forming a microbial preparation by supporting a carrier that supports the above microorganisms. In this case, the above three types of microorganisms may be used in combination, or a combination of two types may be used; or one type may be used. Due to the use of mesophilic microorganisms as biological agents, the temperature of raw garbage treatment is preferably 15°C to 35°C. When the temperature exceeds 35°C, the activity of microorganisms is slow, which is not ideal. There is no need to raise the temperature to 37°C to 65°C as with ordinary aerobic microorganisms and high-temperature microorganisms. Therefore, it is possible to save electrical costs when the garbage disposal device operates, and to reduce the device manufacturing cost.

The amount of microorganisms put into the raw garbage varies according to the composition of the raw garbage and the degree of contact between the temperature and the air. In addition, the microorganism itself can not be limited because it proliferates while decomposing raw garbage. However, in general, for 100 kg/day of raw garbage (containing water), the biological preparation is 750 g, the porous ceramic 11 is 30 kg, and is made of resin. The capacity of the buffer material 12 is 250Ⅼ. The processing time of raw garbage in this standard condition is rice or pasta for 2 hours to 5 hours; for vegetables or fruits it takes 8 to 24 hours. In addition, the skin of onion and bamboo shoots with a lot of fiber may take more than 20 hours. This is because, before being put into the garbage disposal machine, the processing time can be shortened due to the miniaturization in advance. Also, since it is not possible to break down large bones such as cows or pigs, it is necessary to remove them beforehand.

The size of the microorganisms contained in the biological preparation is 0.7 to 0.8 μm in width and 2 to 3 μm in length, and about 200 million microorganisms grow in 1 g of the biological preparation. These microorganisms are mixed with the porous ceramic 11 and the resin-made buffer material 12 by stirring by the stirring blade 1 (standard condition is 3 RPM), and then passed through water (standard conditions are 1 hour and 3 times, 1 minute each) And proliferation. When multiplying in an ideal state, 800 million cells will multiply approximately 4 times after 1 hour, and 1.7×10 ¹⁸ cells will multiply after 24 hours. Microorganisms grow in many holes on the surface of the porous ceramic 11 and in the space portion of the surface area of the resin-made buffer material 12 and multiply, and fly out of them by stirring and start to decompose raw garbage. Even if it is only a porous spherical ceramic support A, microorganisms can be multiplied. When the cylindrical polypropylene support B is not added, the spherical ceramic support A stays in the garbage disposal device Fixing the bottom part 9 of the treatment tank may cause wear on the bottom part of the device. When the cylindrical polypropylene-made support B is added, microorganisms will multiply in the cylindrical surface and act as the pressure in the bottom surface of the dispersing device. The porous spherical ceramic support A has a buoyancy and is suspended in water when the ball diameter is 4 mm or less, so that the effect of cutting and breaking raw garbage is reduced, so it is necessary to replenish regularly. Microorganisms used as biological agents will not proliferate permanently and will die for 3 to 4 weeks of life, and will be discharged together with drainage; or sometimes they will die due to contaminants from raw garbage. It is therefore necessary to supplement regularly. <Example>

In order to test the decomposition effect of microorganism-based raw garbage, the deposit number: IMI-1 (bacillus subtilis) deposited by NITE P-02373, deposit number: IMI-2 (bacillus amyloliquefaciens) deposited by NITE P-02374, deposit Number: IMI-3 (bacillus subtilis subsp.linaquosorum) deposited in NITE P-02375 and confirm the raw garbage disposal capacity held by individual microorganisms. First, add 12g of solid solid waste and 40ml of pure water to a 100ml flask. To this, 0.5 ml of the cultured liquid strains IMI-1, IMI-2 and IMI-3 of the aforementioned microorganisms were added, cultured with shaking at 35°C, and solids and suspended matter were separated with a 1.5 mm (hole) sieve. Then, centrifugal separation (10,000xg, 5 min, 4°C) was used to separate the suspended material and supernatant. Then, the supernatant is diluted to measure BOD (biochemical oxygen demand) or COD (chemical oxygen demand). The weight of the solid matter and suspended matter in each flask 5 days after the start of the experiment is shown in Table-1. <Table 1> The weight of solids and suspended matter in each flask 5 days after the start of the experiment Solids (g) Suspended material (g) Pure water 1.9 11.6 IMI-1 0.2 6.2 IMI-2 0.2 11.8 IMI-3 0.2 6.4 Compared with the amount of solids using pure water without added cultured microorganisms, the amount of solids with added cultures IMI-1, IMI-2, and IMI-3 was reduced by about 14.1% to form a solution. It can be presumed that due to the effects of the addition of IMI-1, IMI-2, and IMI-3, the solids are destroyed and reduced, and then form a solution. It can be inferred that this is because the solids and suspended substances added to the culture medium of IMI-1 and IMI-3 were compared with the total amount of solids and suspended substances that were not added with pure water for the cultivation of IMI-1 and IMI-3. The total amount is reduced by about 47.4% and about 48.9%. The destroyed solids form a solution, and further become organic matter and are metabolized by microorganisms. From the above experimental results, it can be confirmed that: IMI-1, IMI-2, and IMI-3 are effective for the liquefaction of raw waste; it can also be confirmed that IMI-1 and IMI-3 are effective for organic matter (solid matter) , And suspended substances) is an effective fact. <Industry availability>
