Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to foods containing waste such as garbage or flowers discharged from kitchens installed in limited areas such as accommodation facilities such as hotels and inns, factories and hospitals. The present invention relates to a kitchen waste recycling system and method for recycling garbage and wastewater.

[0002]

2. Description of the Related Art Conventionally, raw garbage discharged from kitchens installed in limited areas such as hotels, inns and other accommodation facilities, factories, hospitals, etc. is transferred to general garbage and other cleaning departments for disposal as general garbage. Or passed to compost manufacturers for processing.

[0003] Wastewater discharged from kitchens installed in limited areas such as accommodation facilities such as hotels and inns, factories and hospitals is generally drained into sewage installed in municipalities. In addition, accommodation facilities such as hotels and inns, factories,
When a sewage desalination plant is installed in a limited area such as a hospital, the wastewater discharged from the kitchen is separated into sewage and sludge by the sewage desalination plant, Some of the water is reused for toilet wash, car wash, water sprinkling, etc., and the rest of the middle water is drained to sewage installed in municipalities.

[0004] Sludge generated in the process of the Nakamizu desalination plant is disposed of as industrial waste by requesting a specialist to treat it.

[0005]

By the way, garbage discharged from a kitchen installed in a limited area such as an accommodation facility such as a hotel or an inn, a factory or a hospital is transferred to a cleaning unit such as a municipal government. Even in the case of processing by burning, it is difficult to transport garbage, and the cost is enormous. Moreover, the amount of garbage transferred to the cleaning departments of municipalities is increasing year by year, and it is currently difficult to dispose of them at the cleaning departments of municipalities.

[0006] The garbage delivered to the compost manufacturer is subjected to a conventionally known fermentation treatment to produce compost. In this conventional fermentation treatment method, even if a lot of large lumps are contained in the garbage, the dry powder is mixed by simple calculation to adjust the water content and calculate the water content. However, this means that the contents of the raw garbage remaining as a lump in the desk calculation remain at the same water content of 90 to 80% as before mixing.

[0007] That is, the raw garbage in the form of a lump is mixed with dry powder only in the surface portion to have a water content of 40 to 50%,
Aerobic fermentation is caused by contact with oxygen. However, since the inside is not adjusted in water content and does not come into contact with oxygen, anaerobic fermentation with a bad smell starts. The larger the mass, the longer this condition lasts, after which the cell tissue inside the anaerobic fermented mass is destroyed, and the mass disappears and is mixed with the dry powder to make effective moisture control and contact with oxygen. When possible, it has shifted from anaerobic fermentation to aerobic fermentation.

[0008] Therefore, even if any water regulator is mixed, the water content cannot be adjusted up to the internal cell tissue in the garbage, and anaerobic fermentation and aerobic fermentation occur simultaneously. There was a problem that occurs.

[0009] In addition, sludge generated in the process of the Nakamizu desalination plant is treated as industrial waste by a professional contractor and disposed of by disposal. Accompanied.
