As the amount of food waste increases, local autonomy in each region is becoming a big problem. Food waste is badly odorous and leachate is not well biodegradable, so it can not be treated by conventional treatment methods. Therefore, most of it is treated by consignment treatment and consignment treatment by using marine dumping or sewage treatment. It is completely blocked and its handling problem is in serious condition.

A common technique for treating food waste is a method of separating leachate from food waste in a collection tank, drying the solid material to high heat to produce livestock feed, or fermenting it as microorganisms to produce compost and recycle food waste It is dominant. However, such a method also requires a lot of energy and expensive facilities when food waste is developed as a feed, causing economic problems and losing quality to feed and livestock farmers. Composting also requires a lot of work to be commercialized in that saliva contamination of the soil and fermentation of microorganisms due to the lack of development of saliva processing technology have a wide working space and long processing time.

The technical point of each process of the present invention will be described as follows.

<1 step>

In the electrolysis method, silver, copper and zinc are the highest evaluated as antimicrobial or sterilizing metals at present, but zinc and copper inhibit their use because they cause genetic mutation in human body. However, zinc oxide has been used as a remedy for perspiration since ancient times.

Currently, silver (Ag) is highly valued as an antibacterial metal, but it is pointed out that the price is high. Zinc also has a sterilizing and deodorizing function that is as good as silver (Ag) but its use is prohibited by zinc itself. In the present invention, when the zinc alloy is electrolyzed in the electrolytic process, the zinc is oxidized and becomes zinc oxide. Thus, the zinc alloy is used

In particular, potassium permanganate, which is used as a strong oxidizing agent for electrolytes, is used not only because of its excellent oxidizing power but also because of its sterilizing deodorizing ability and because it can enhance strong sterilization and deodorizing function when zinc is dissolved with potassium permanganate.

It has been reported that there is no bacteria that can survive for 6 minutes in contact with zinc and silver which are antibacterial metals.

If the temperature rises in the garbage disposal area, it is impossible to access it without wearing the gas mask. The smell of food waste is sterilized by bacterial smell and the smell is instantly deodorized.

However, it is possible to instantly deodorize with instant disinfectant at the food waste disposal site with the existing disinfectant or the quaternary ammonium type disinfectant, but it is the technology of the existing disinfection and deodorizing agent that the deodorization occurs when the bacteria grows within a few minutes after use.

Currently, sterilization and deodorization of silver nano fungicide has excellent deodorizing function, but the price is high.

As described above, the nano zinc carbon sterilizing potassium permanganate deodorant according to the present invention is strongly sterilized at the moment of being immersed in food garbage, and the nano zinc is granulated to about 5 nanometers to be excellent in dispersibility, permeability and ionicity, It has the function of semi-permanently deodorizing the inside and the surface of the food while it is deeply digging into the garbage.

In addition, the nanocarbon is also granulated at 5 nm to have a positive ion, that is, a quantum property, an excellent adsorption power, a sterilizing and deodorizing function, and a nano zinc carbon composition is dissolved in potassium permanganate to maximize its functional effect.

In general, 1kg of ionized water of nano silver is 1000 times larger than 1000kg of silver powder, and its function effect is several thousand times higher than that of sterilization. It is understood that the technology and characteristics of nanoparticles of antimicrobial metal are generally announced in various papers and experiments.

1 kg of the above-mentioned nano zinc carbon potassium permanganate solution is mixed with 1000 kg of food garbage, and it is proved that it has an excellent sterilizing and deodorizing function and excellent economic effect.

<2 steps>

When the food garbage is collected in the collection tank for 2 hours to 3 hours, the water contained in the food garbage is passed through the filtration device and naturally separated by the leachate.

<Step 3>

1000 kg of the food waste separated in the above two steps and 1 kg of the nano zinc carbon potassium permanganate solution prepared in the above step were mixed and sterilized and deodorized.

<Step 4>

The use of the two-stage grinding machine for food waste is a waste of about 3,000 calories, since the food waste is made of carbon compound of 80% or more. Therefore, since waste vinyl is abundant when discarding food garbage, the waste vinyl and the waste vinyl which can not be recycled It is preferable that 1000 kg of the food waste and 200-300 kg of waste vinyl are mixed and crushed by a two-step crusher.

<Step 5>

In the case where the pulverized food waste and the waste vinyl mixture are mixed in an amount of 200 kg in the case of 1000 kg of the briquet powder, the mixer is preferably a screw type mixer.

It is preferable to produce by extrusion in the extrusion process of the briquette production process by the conventional method of manufacturing 19 coals.

&Lt; 6 Process >

In the present invention, instead of water, 1000 kg of briquette powder is mixed with 50 kg of food waste leachate and the briquette is mixed with the conventional briquetting extrusion process. .

Hereinafter, the present invention will be described in detail with reference to examples.
