DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus capable of decomposing organic substances (such as garbage and cooking effluent) generated mainly in a kitchen at home with microorganisms and flowing the garbage through a sewer pipe. .

[0002]

2. Description of the Related Art In a conventional garbage processing apparatus, a garbage generated in a sink is provided with a device for drying and reducing the weight, a device for incineration, a device for decomposing by microorganisms, and a crushing means. It is considered that the garbage is pulverized and flown into a sewer system, and that the garbage is pulverized by a pulverizing means, and then the pulverized garbage is stored in a decomposition tank in which microorganisms live, and the organic matter is decomposed by the microorganism.

In particular, in the case of crushing garbage in a sink, the garbage can be processed in a kitchen sink where garbage is generated.
Furthermore, it is convenient without any waste after maintenance and treatment, but since the crushed garbage is poured into the sewer as it is,
Biochemical oxygen demand (BOD) of garbage and kitchen wastewater increases. In order to reduce this BOD, after the garbage is crushed by the crushing means, the crushed garbage is not directly poured into the sewer, but is poured into a decomposition tank provided with a filter medium to which microorganisms are attached, and the garbage and kitchen drainage are discharged. A garbage disposal apparatus that decomposes organic matter with microorganisms in a decomposition tank has been considered.

[0004]

However, in such an apparatus, it is required to increase the decomposing ability and the decomposing rate of organic substances and to increase the size and performance of the apparatus. For that purpose, it is necessary to perform aerobic microbial decomposition in which organic substances are decomposed by aerobic microorganisms. However, in the case of aerobic microbial degradation, oxygen is always required for the degradation, and the growth rate of the microorganisms is also high. The excess microorganisms close the gap between the filter media in the above-mentioned decomposition tank, and supply oxygen to the microorganisms. And the decomposition performance of organic substances is greatly reduced. Also,
In order to solve this problem, it has been considered to stir the filter medium of the decomposition tank using a stirring means to scrape off excess microorganisms and eliminate the blockage of the decomposition tank. The problem is that the material is scraped off and the decomposition performance is reduced. Further, there is also a problem that a small hole in a partition portion between the decomposition tank and another tank is closed, and the decomposition performance is similarly reduced.

The present invention has been made to solve the problems of such a garbage processing apparatus, and to provide a garbage processing apparatus in which the decomposition ability and decomposition rate of organic substances are increased.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a decomposition tank filled with a filter medium on which microorganisms are implanted in order to decompose organic substances by microorganisms, and stores water passing through these tanks. A water tank connected to a sewer pipe, and a stirring means for stirring the filter medium in the decomposition tank, a partition plate provided with a number of small holes for separating the decomposition tank and other tanks, the stirring means of the decomposition tank At least one of the several stirring rods provided orthogonal to the rotation axis is configured to rotate in proximity to or in contact with the partition plate. According to this configuration,
If excess microorganisms are generated simultaneously with the aerobic microbial decomposition, the partition plate between the decomposition tank and other tanks that cannot be stirred by the stirring means in the decomposition tank is blocked, and oxygen cannot be supplied to the microorganisms, greatly degrading organic matter. The problem of deterioration can be prevented. In other words, the stirring rod is used to scrape off excess microorganisms and prevent the partition plate from being blocked.
