Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for disposing of kitchen waste disposed of from households, and in particular, a method for processing kitchen waste disposed of every day in a small container in a very rational manner to prevent the accumulation of kitchen waste. The aim is to prevent this.

Generally, kitchen waste that is disposed of from households is stored exclusively in garbage buckets or polyethylene bags, and is collected on garbage collection trucks that make rounds at a fixed time and transported to a fixed location where it is disposed of. .

However, the amount of kitchen waste that is discarded every day is enormous and has a bad odor, making the disposal of this kitchen waste a big burden and a source of trouble.

In addition, in areas where garbage collection trucks are not available, methods such as digging a hole in the corner of the garden and dumping kitchen waste there are used, but this method may be damaged by dogs, cats, etc., or may be infested with insects. , it was an unsanitary disposal method.

It should be noted that there is a conventional method for producing compost using kitchen waste disposed of from households, but this method only converts kitchen waste into compost and does not take any means to eliminate kitchen waste.

In other words, in the compost production method, a wooden frame is built, and household kitchen waste such as weeds and fallen leaves are put into it and piled up to create compost.The purpose is to convert the kitchen waste into fertilizer.
It is not intended to eliminate and dissipate kitchen waste.

Therefore, in the compost production method, kitchen waste is turned into compost by aerobic fermentation, and nitrogen is fixed in the compost.

For this purpose, it is necessary to mix a large amount of fallen leaves, straw, etc. with kitchen waste, since it is too watery and has a low solid content such as cellulose, so it cannot be converted into compost, and enzymes are also added in advance.

Furthermore, in order to carry out aerobic fermentation, a large number of ventilation holes are inserted into the frame.

As a result, bad odors are emitted from the ventilation holes, and insects and other insects can come in and out, making it unhygienic.

Furthermore, when making compost, it is necessary to turn the compost from time to time, so the frame usually does not have a lid, but is simply covered with a tin plate or a wormhole, which makes it look unsightly and unhygienic.

Furthermore, since the purpose was to produce compost, it could not be used in every household.

The present invention was developed as a result of intensive research aimed at improving these shortcomings. By utilizing the purifying action of bacteria and microorganisms that live in the soil, kitchen waste can be digested extremely easily, and eventually become nitrogen and carbon dioxide gas. It was discovered that because it is broken down into small pieces and dissipated into the air, it disappears to the point where it hardly retains its shape.

That is, in the method of the present invention, a container with a top lid and no bottom plate is placed upright without digging a hole in the soil, the lower part of the container is slightly buried in the ground to prevent it from tipping over, and the container is placed inside the container. A desired amount of kitchen waste and soil are alternately added and left to stand, and the kitchen waste is destroyed by soil bacteria.

The container for carrying out the method of the present invention has a top lid and no bottom plate, and a flange-like projection is provided around the bottom of the container body.

Therefore, according to the present invention, instead of digging a hole in the ground and burying the kitchen waste, the kitchen waste is put into a container placed on the ground without digging a hole in the ground, thereby achieving the same effect as burying it underground. It requires less labor (it is very easy to use, and a large amount of kitchen waste can be hygienically disposed of using a container with a limited capacity, so it can be used for kitchen waste disposal even in households with a small amount of open space).

In the present invention, a container without a bottom plate is installed upright without digging a hole in the soil, and the lower part of the container is buried in the ground, for example, several depths of depth, to prevent it from tipping over. By repeating the process of flattening wet garbage such as grass to a height of 5 to 30 CIrL and then sprinkling soil on top of this to a height of 2 to 5 CIrL, the kitchen waste decomposes and is absorbed into the soil. It is digested by the fungi and microorganisms that live in the kitchen and almost completely disappears, and the purpose is to sufficiently decompose kitchen waste into gas so that no residue remains.

In addition, the soil added at this time has the effect of absorbing and purifying the wastewater generated when kitchen waste rots and is digested or destroyed by fungi and microorganisms, thereby preventing foul odors and wastewater from leaking out of the container.

Therefore, kitchen waste that was bulky at the time of dumping has reduced in weight to the extent that it remains almost at the bottom of the container after a few days, and by preparing only 1,001 containers in a standard household, containers can be stored for more than a year. is never full of kitchen waste.

As described above, in the present invention, there is no need to input enzymes as seeds; rather, anaerobic fermentation is preferable, and soil bacteria etc. process the kitchen waste, so that most of the substances that eventually accumulate in the container come from the soil that was input later. Since it is a substance that has been turned into soil and has no bad odor and does not have the appearance of filth, it may be sprayed on the ground as it is.

In addition, this soil absorbs organic nitrogen produced by the decomposition of kitchen waste, so it can be used as soil for home gardens, etc.

Therefore, there is no need to provide a ventilation hole in the container, which prevents odor from leaking to the outside and allows sanitary processing.

The top surface of the kitchen waste should be covered only with soil, preferably soil containing an appropriate amount of moisture, and the use of lime, wood ash, etc. should be avoided.

Further, the container used in the present invention may be any container as long as it has a lid on the top and does not have a bottom plate (its shape may be either cylindrical or rectangular).

Furthermore, by making the container wide in diameter at the bottom and tapering toward the top, it is advantageous to increase stability when placed on the ground.

Furthermore, by providing a flange on the outer periphery of the bottom, by embedding the container slightly into the ground, the container is more firmly fixed by the flange, which prevents the container from being knocked over by dogs, cats, etc., and also prevents the container from falling over. can be reinforced.

Furthermore, it is possible to prevent sewage generated by the decomposition of kitchen waste from leaking from the lower part of the container around the outer periphery of the container to the ground surface.

Further, it is desirable that the upper input opening be wide, and the lid should be designed so that it cannot be removed by dogs, cats, etc., and it is sufficient that rainwater does not enter the inside of the container.

This prevents the soil inside the container from being washed away and prevents it from becoming overly moist and provides adequate heat retention.

Therefore, there is no need for a sealed structure.

In addition, the material should be one that does not rot due to soil or other substances, and is usually made of plastic.

It is also desirable that the soil covering the surface of kitchen waste be loosened and made into fine particles, thereby activating the activity of soil bacteria.

Kitchen waste, weeds, etc., which are discarded from the kitchen, are thrown into the container thus installed so as to be as flat as possible, and the containers are stacked to a height of about 20 crIL.

Spread soil on top of it to a height of about 2 to 3 cI'Il, stack kitchen waste and soil alternately, and leave it as it is, so that the kitchen waste can decompose and disappear.

Next, examples of the present invention will be described.

Example As shown in FIGS. 1 and 2, the bottom plate of a large plastic container body 1 with a volume of 1001 was cut out and reversed to form a container with an upper diameter of 460 mm, a lower diameter of 600 TtrrL, and a height of 6.
00 basket has a downward opening slope, the cutout part is used as an input port, and the lid 2 is attached here, and the bottom has a width of 5 cr/l.
The soil was excavated to a depth of approximately 5 cIrL at the location where the container provided with the flange 3 of about 100 liters was to be buried in the soil, and the container was firmly buried there with the flange 3 interposed therebetween.

Then, put kitchen waste disposed of from the kitchen into the above container.
When the 22nd time is about 20cm thick, pour about 2cra of soil on top.

The next day, I continued to dump kitchen waste on top of it.

In the first month, I added soil to a thickness of 2 cm for the second time.

When kitchen waste and soil were repeatedly added in this way, after three months, the contents in the container were about 10 times the size of the container, and after 6 months, the contents were only about 10 times the amount, and the container was full. It took about a year.

It is preferable to provide step portions 4, 4' at desired positions on the circumferential surface of the container body so that the amount of garbage inside the container body can be easily indicated.

・Therefore, the amount of kitchen waste disposed of by households has been significantly reduced to less than 10,000 yen from the previous level.

Moreover, the soil material remaining in the container after 1 year was mostly silica, with only a small amount of hard-to-decompose materials mixed in, such as egg shells, bones, and thick wood.

Also, there was no bad odor at all (it could be used as soil for home garden plants, etc.).

As detailed above (according to the method of the present invention, there is no need to dig a hole in the ground, and most of the kitchen waste disposed of from households can be hygienically disposed of and destroyed in each household on the ground). It has remarkable effects, such as greatly reducing the burden on garbage collection vehicles and significantly improving garbage disposal.
