As shown in FIG.
Is formed in a flat plate shape having a length of about 2 to 5 mm and a horizontal length L and a vertical length of about 5 to 15 mm. Also, this wood piece 100
Is formed from the cedar tree,
Is cut along the length direction of the cedar tree conduit so that the conduit extends in the vertical direction of the small wood piece 100. The upper and lower surfaces 101 and 102 of the small piece of wood 100 are inclined surfaces, so that the surface area of the upper and lower surfaces is increased, and the exposed area of the cedar tree conduit is increased on the upper and lower surfaces. On the other hand, the front and rear surfaces 103 and 104 of the small wood piece 100 are formed in a wavy shape.

[0014] The small wood pieces thus formed are planted so that microorganisms can be viable. This treatment is performed by treating the wood pieces so that the microorganisms can survive in a space such as a conduit for the wood pieces, and then attaching the microorganisms to the wood pieces. The shape is increased to increase the surface area of both front and rear surfaces, and the surface area of both upper and lower surfaces is increased, so that microorganisms are easy to adhere to. Since the exposed area of the conduit included in the container is increased, microorganisms can easily enter the conduit. The microorganisms used may be those conventionally used for garbage activating treatment. The size of the small wood piece 100 is not limited to the above, but the thickness is 2 mm or less and the horizontal and vertical length is 5 mm.
If it is less than mm, the number of conduits in which microorganisms survive will be reduced. In other words, the efficiency of treatment by microorganisms is rather deteriorated. Therefore, in such a point, the thickness is about 2 to 5 mm, and the horizontal and vertical lengths are 5 to 5.
It is preferable to form it into a flat plate of about 15 mm. In addition, the front and rear surfaces of the small piece of wood 100 are formed in a wave shape, but the present invention is not limited to this embodiment. Etc. can be changed as appropriate, at least one surface may be formed in a wave shape, by doing so,
Microorganisms can be more easily adhered than those having a flat front surface.

In order to treat garbage using the organic waste treatment apparatus configured as described above, a plurality of wood chips 100 shown in FIG.
Operate the organic waste treatment equipment. In this embodiment, the amount of the small wood pieces 100 to be put in the storage tank 1 is stored by about 20 m ³ . Then, the organic waste treatment device is operated. Then, the lids 3 ... 3 are opened, and the input ports 2 ... 2
Raw garbage is put into the storage tank 1. At that time, lid 3 ... 3
The rotating shaft 12 stops in conjunction with the opening of the
Since the apparatus 1 is also in a stopped state, it is possible to prevent a person who is supplying organic waste from being accidentally hooked on the rotating stirring blade 11 and drawn into the storage tank 1 during the charging. In addition, the amount of garbage to be input is maximum,
It is preferable to set the volume ratio to about 4 to 5%.

The garbage put into the storage tank 1 is eaten by microorganisms living in the small wood pieces 100 and decomposed into water and carbon dioxide. At this time, the temperature in the storage tank 1 is constantly maintained at 20 to 30 ° C. by the temperature adjusting means, and oxygen is supplied to the storage tank 1 by the oxygen supply means. The microorganisms living on the small wood piece 100 can be maintained in a viable and activated state, and the garbage can be efficiently consumed in a short time. Note that the amount of garbage that can be processed in one day by the apparatus according to the present embodiment is about 1000 kg, although it varies depending on the type of garbage.

In the storage tank 1 after the garbage is eaten by the microorganisms, the garbage completely disappears, but is filled with carbon dioxide gas which gives off a foul odor. This carbon dioxide gas is sucked from the suction port 31 and sent to the guide path 34 of the deodorizer 33. During the passage of the guide path 34, water is sprayed from a plurality of small holes 35a. It is deodorized. Further, since ozone is sent to the guide path 34, the carbon dioxide gas is deodorized and sterilized by the ozone when passing through the guide path 34. The deodorized and sterilized carbon dioxide gas is discharged to the outside from the exhaust port 37 of the deodorizer 33 without harming the human body.

In the present embodiment, the organic waste treatment apparatus has the storage tank 1 of about 25 m ^3. However, the present invention is not limited to this form. What is necessary is just to make it suitable for obtaining, and it can change suitably.
