e), red sulfur-free bacteria (Athiorhodaceae) and the like.

The waste disposal medium of the present invention can be regenerated by, for example, washing it with water and then drying it in the sun.

A method for producing a refuse treatment medium A refuse treatment medium in which Bacillus sphaericus coexists with photosynthetic bacteria can be produced by irradiating a ceramic piece having a hole in which Bacillus sphaericus inhabits with fluorescence.

For example, it can be produced by placing a ceramic piece having a hole in which Bacillus sphaericus inhabits in a transparent container such as glass and sealing it, and culturing it at 30 ° C. and 5000 lux illumination for 2 days.

As the ceramic piece, a porous ceramic piece can be used. The shape of the ceramic piece is not particularly limited, and for example, a spherical shape (ceramic ball), a cylindrical shape, and a rectangular parallelepiped shape can be used. In view of the above, a spherical one (ceramic ball) is preferable.

The size of the ceramic piece is not particularly limited, but usually, the maximum diameter (diameter) is 1 to 50 m.
m, preferably about 2 to 30 mm, more preferably about 3 to 10 mm.

As the ceramic piece, the maximum diameter is 1 to
Those having holes of about 30 μm, preferably about 2 to 20 μm, more preferably about 3 to 10 μm can be used.

As the ceramic piece, for example, the occupied area of the hole is about 20 to 80% of the surface area, preferably 3 to 80%.
About 0 to 70%, more preferably about 40 to 60% can be used.

Dust Treatment Method Dust can be decomposed by bringing the dust into contact with the waste treatment medium of the present invention. The refuse treatment medium and the refuse can be brought into contact by mixing and stirring. The temperature at which garbage comes into contact with the garbage disposal medium is
For example, about 10 to 40 ° C, preferably 15 to 35 ° C
Degree, more preferably about 20 to 30 ° C. Although it depends on the cultivation conditions of the bacteria that decompose the dust, the dust can usually be decomposed by contacting the dust with a dust treatment medium for 20 to 80 hours.

The refuse to be treated in the present invention can be raw refuse, and can be refuse mixed with a polymer material. According to the present invention, for example, the following materials are decomposed,
Can be processed.

According to the present invention, for example, cardboard,
Milk pack, Newspaper, Copy paper, Kim towel, Tea bag, Coffee filter, Tangerine peel, Apple peel, Banana peel, Corn core, Leek, Leek, Cabbage core, Spinach, Edamame, Carrot, Beef / Pork meat, Bone Chicken, tuna lean, boiled, fried noodles, bread,
Agar, hardened edible oil, tofu, uncooked vegetables, crab shell, clam shell, clam shell, camellia fallen leaf, kuma bamboo leaf, grass,
Organic materials such as tea leaves, cigarette butts, wood chips, thin veneer boards, split chopsticks, absorbent cotton, and towels can be processed.

If the refuse to be treated is large, it can be crushed before contact with a refuse treatment medium, if necessary. For example, if the maximum diameter (diameter) of garbage is 1 to 10c
The processing efficiency can be improved by crushing into a chip shape of about m, preferably 2 to 5 cm.

If the moisture content of the refuse to be treated is high, it can be dewatered before contact with the refuse treatment medium, if necessary. For example, the water content is 50% by weight or more, usually 60% by weight or more, especially 70-80%.
By setting the moisture content of the refuse by weight to 40 to 50% by weight, the processing efficiency can be improved. In addition, by dewatering the dust, it is possible to remove salts (for example, sodium chloride, preservatives) and the like that have an adverse effect on bacteria that decompose the dust.
