Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse treatment apparatus using an enzyme agent.

[0002]

2. Description of the Related Art In the case of garbage disposal, conventionally, incineration is generally performed.

However, when garbage, especially garbage, is incinerated, if the incineration temperature is low, dioxin, a highly toxic substance, is generated from the salt contained in the garbage, which is a major problem.
In addition, other toxic gases are also generated and cause environmental pollution, which is a social problem. Incineration of garbage is prohibited in developed countries, especially Germany and the United States. The London Treaty now also prohibits the dumping of garbage at sea.

[0004] Therefore, it is conceivable to dispose of refuse using a catalytic reaction of an enzyme.

[0005]

However, the components of garbage, especially raw garbage, are various with various carbohydrates, vegetable and animal proteins. The catalysis is very specific,
It acts only on one type of substance or on substances with a common structural element. Therefore, a conventional apparatus using an enzyme agent capable of simultaneously decomposing various components as described above requires a great deal of time for the treatment. In addition, since the decomposition accuracy of the treatment is poor, there is a disadvantage that putrefaction odor is generated in the course of the treatment.

According to the present invention, based on the above background, it is possible to treat organic waste such as garbage composed of various components in a short time, and to perform this treatment without putrefaction odor and cleanly. It is intended to provide a refuse treatment device.
