It has various problems such as the occurrence of pollution.

[0003] In recent years, fermentation of garbage using aerobic microorganisms has been studied to solve these various problems. This garbage fermentation process is carried out in a processing tank.
A fermentation treatment material containing garbage and aerobic microorganisms is accommodated, stirred, and the garbage introduced into the fermentation treatment material is decomposed by aerobic microorganisms into proteins and fibers. It has the advantage that it can be reduced (disappeared) to 10/1/30. Therefore, garbage is now not a waste to be incinerated, but garbage fermentation is being promoted from the standpoint of environmental protection.

[0004] The aerobic microorganisms (hereinafter referred to as "fermenting bacteria") exhibit activity at a temperature of about 30 to 50 ° C (some thermophiles exhibit activity at higher temperatures). The fermentation bacteria are usually sawdust, firgrass, coffee dregs,
Using fermentation treatment material contained in powdery or granular materials such as ceramic particles as a bacterial bed, stirred in a stirring vessel, activated by contacting with air, and fermented the inserted garbage I have.

[0005]

However, the bacterial bed using the above fermented material is easily oxidized in the process of fermenting the raw garbage, and the oxidative degradation of the bacteria causes the odor to be worse than that of the garbage. There is a fear that it may cause the generation of

In view of the above, the inventor of the present invention has conducted long-term studies and found that, when the fermentation treatment material is stirred in a stirring vessel, the fermentation is carried out by adding an alkaline holding material such as granular coral. Finding that the processing material does not oxidize,
Finally, the present invention has been completed, and it is an object of the present invention to provide a bacterial bed for garbage fermentation treatment which improves the function of fermentative bacteria and does not generate a bad odor from garbage.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a fermentation treatment material comprising powdery or granular materials such as sawdust, firgrass, coffee dregs, and ceramic particles having fermentative bacteria. It is characterized by mixing alkali possessed material such as coral or its processed products, keeping the fermentation treated material simple and alkaline for a long time, making fermentative bacteria easy to activate, and creating an environment suitable for propagation Is made so that garbage can be efficiently fermented.

The inner surface of the stirring vessel 1 has a semicircular arc E (a plurality of semicircular arcs may be continuous in the diameter direction), and the stirring generator 1 is operated by a vibration generator 6 installed via a mounting frame 5 below the bottom center thereof. The bacteria bed 10 can be agitated. This stirring means is different from the case where the bacterial bed is stirred using the rotating blades,
Even if foreign matter such as a knife or a spoon is contained in the garbage, there is no problem, and there is an advantage that a dead bed portion in which a germ bed or a part of the garbage stagnates is not formed in the container.

As shown in FIG. 2, the bacterial bed 10 of the present application is a fermentation treatment material 11 composed of powdery or granular materials such as sawdust, firgrass, coffee dregs, and ceramic particles that hold fermentative bacteria.
And an alkaline holding material 12 such as granular coral or a processed product thereof. The mixing ratio is not particularly limited, but the fermented material 11: the alkali-containing material 12 is 90 to 50:10.
About 50 is preferable.

[0010] The alkali-containing material 12 comprises
Is maintained in an alkaline state, and granular corals or processed products thereof are suitable, but granular oyster shells or processed products thereof may be used. However, even if slaked lime is mixed with the fermentation treatment material 11, it is possible to maintain the alkali. Therefore, use of slaked lime is not denied. Required. In this regard, granular corals or their processed products,
Alternatively, in the case of a granular oyster shell or a processed product thereof, the bacterial bed can be kept alkaline for a long time only by mixing it with the fermented material 11 and stirring.

The granular coral and the granular oyster shell are as follows:
The crushed coral and oyster hulls having an average grain size of about 5 mm to 10 mm may be used. Corals and oyster shells can be of any type and origin. The processed products of corals and oyster hulls include those obtained by solidifying powdered pulverized materials with a certain connecting material (for example, an adhesive).

In the illustrated example, the vibration generator 6 has a motor 6a in which an eccentric weight 6b is fixed to a conical shaft 6a ', but other types (for example, utilizing the repulsion of an electromagnet). Thing). Thus, the vibration generated by the eccentric weight 6b turning clockwise (arrow) is mainly transmitted to the left wall side of the container 1, and the secondary vibration is transmitted to the right wall side. The present bacterial bed 10 in the container rotates in the A direction. When changing the rotation direction of the bacterial bed 10 of the present application,
What is necessary is just to reverse the rotation direction of the eccentric weight 6b of the vibration generator 6.
