Abstract

PURPOSE:To efficiently decompose org. matter without generating a problem with respect to preservation of the environment by making the average size of the carrier received in a purifying tank larger than that of the carrier received in a treatment tank. CONSTITUTION:Saccharides, amino acids, org. matter and the like are contained in water generated by the decomposition of garbage but these components are decomposed by microorganisms, especially, bacteria propagated on a carrier 6 while purified water is drained. This water purification is mainly performed by the whole of the carrier 6 in a treatment part and further performed by the carrier 6 in a purifying part. Since the average size of the carrier 6 in the purifying part is made larger than that of the carrier 6 in the treatment part, the drainage of the purifying part is improved and, in addition, the drainage of the treatment part is enhanced and the air permeability of both parts is also enhanced. Therefore, Aschelminthes or microorganisms are activated and the decomposition treatment capacity of org. matter is enhanced.

In use, first, the carrier 6 having a large average size which constitutes the purification section is put in the treatment tank 5, and thereafter the carrier 6 having a small average size which constitutes the treatment section is put therein.

Then, when the kitchen waste is discarded from the disposal port 32 by opening the lid 34 of the apparatus body 1, the kitchen waste is slid down the shooter 31 due to its weight, and the shutter 33 is opened to be discarded in the processing tank 5. It

When the lid 34 is closed and an operation switch (not shown) is operated, the electric motor 8 is driven for about 1 minute, the kitchen blades are mixed with the carrier 6 by the rotation of the stirring blade 11, and the inside of the carrier 6 is stirred by stirring. Supply air to. Further, the pump 22 operates to supply air into the treatment tank 5 and evaporate excess water contained in the carrier 6, thereby activating sachet-shaped animals and microorganisms that propagate on the carrier 6.

The stirring blade 11 is driven every predetermined time, in this embodiment, every 4 hours, and air is supplied into the carrier 6 to activate slugs and microorganisms.

On the carrier 6, bag-shaped animals such as ringworms and nematodes attached to the kitchen waste by disposal of the garbage into the processing tank 5 and microorganisms such as protozoa and bacteria are propagated, and mainly the ringworms. Worms and nematodes and protozoa eat and dispose of garbage. The decomposition of organic substances by the bag-shaped animals and microorganisms is mainly performed in the processing section of the carrier 6. Since the pump 22 and the blower 24 supply the optimal air for breeding bag-shaped animals and microorganisms to the treatment tank 5 and maintain the optimum humidity, the kitchen waste disposed of in the treatment tank 5 is relatively small. It decomposes and disappears in a short time.

The water produced by decomposing the garbage is
The kitchen waste contains components that are produced in the process until it is completely decomposed into water and carbon dioxide, that is, sugars, amino acids, organic acids, etc., but these components are decomposed by microorganisms, particularly bacteria, that propagate on the carrier 6. , Purify and drain. The purification of the waste water is mainly performed on the entire carrier 6, is purified by the treatment section of the carrier 6, and is further purified by the purification section of the carrier 6. Also, wastes and carcasses of bag-shaped animals and microorganisms are decomposed by bacteria. Due to the food chain of the above-mentioned bag-shaped animals and microorganisms, it can be almost completely decomposed without producing malodor and residues.

Since the average size of the purifying section of the carrier 6 is formed to be large, the drainage of the purifying section is improved, the drainage of the treating section is improved accordingly, and the air permeability of the purifying section and the treating section is improved. improves. Therefore, bag-shaped animals and microorganisms are activated,
The ability to decompose organic substances is improved.

When the temperature in the processing tank 5 becomes 25 degrees Celsius or less, the first heating means 16 and the second heating means 20 are energized to heat the inside of the apparatus main body 1 by the second heating means 20, and the first heating means 16 is heated. And the second heating means 20 keeps the carrier 6 in the treatment tank 5 at a temperature of 25 to 50 degrees Celsius which is optimum for the activity of the bag-shaped animals and the microorganisms, activates the bag-shaped animals and the microorganisms and decomposes the garbage. Maintain processing efficiency in good condition.

In the first embodiment, the same carrier 6 is used for the treatment section and the purification section, and the average size of the carrier 6 in the purification section is
Although the size of the carrier 6 of the treatment section is formed larger than the average, the carrier 6 of the treatment section and the carrier 6 of the purification section are made of different materials so that the carrier 6 of the purification section is more breathable and permeable than the carrier of the treatment section.
