Description

Food waste disposal apparatus and method for vanishing food waste using same

The present invention divides the collection chamber of the food waste treatment tank into a plurality of sections, and the food waste treatment apparatus to agitate and extinguish the newly added excipients, the extinction agent and the food waste while sequentially moving each section by a predetermined period. And it relates to a food waste extinction method using the same.

In general, food waste refers to food waste discharged from restaurants, homes, and catering establishments, and agricultural, water, and livestock waste generated during the production, distribution, processing, and cooking of food, and most of the food waste components. Is composed of leachate, water, etc., which is accompanied by a severe odor.

Accordingly, a device capable of treating food waste has been developed. For example, food waste has been adopted to be crushed, crushed or compressed to be landfilled or incinerated, but it is not only difficult to continuously process food waste in large quantities, but water pollution, soil pollution or the like during landfilling or incineration of food waste. Secondary pollution problems such as pollution occur.

In addition, although the amount of food waste can be reduced by using a device capable of processing the food waste, there is a limit in reducing food waste only by the function of simple compression in which water is not completely removed.

As another example, the food waste is disposed of in landfills, but most of the food waste includes leachate, and the leachate of landfilled food waste is absorbed into the landfill soil, causing severe odors and polluting the soil.

As a result, a sanitary landfill was installed on the bottom surface to allow leachate, such as food waste, to flow to a constant reservoir. However, leachate flows through the embankment around the curtain and flows into nearby rivers. If polluting hazards are generated and food waste is left untreated in rivers and mountains instead of in landfills, environmental pollution is further increased.

In addition, although a policy that can use food waste as a resource, that is, composting, feed, fuel, is being implemented, the following problems occur.

When the food waste is put into a composting container for fermentation and used as a plant compost, the fermented food waste contains salt and heavy metals as it is, which causes harm to plants.

Although the plant was established to feed food waste for the feed, the wastewater was generated according to the food waste feed process. This resulted in increased environmental pollution, and it is not suitable because it contains salinity to feed livestock food waste to livestock.

For the fuelization, once the household waste containing food waste is incinerated by incineration, the moisture of the food waste lowers the incineration temperature, and when incinerated, harmful components such as dioxins are generated.

The present invention has been made in order to solve the above problems of the prior art, by dividing the collection chamber of the food waste treatment tank into a plurality of sections, excipients, quenching agents and newly added while moving each section sequentially by a certain period The food wastes can be agitated to be extinguished, and the leachate of food wastes is stored and purified separately, and then the leachate is purified to supply the leachate to prevent them since the excipients are dried in the process of dissipating food wastes for a certain period of time. When the new food waste is added to the excipients that have been activated and extinguished, the extinction effect can be smoothed, the reduction rate and deodorization rate can be increased for the odor generated, and the secondary pollution and odor generated by leachate can be prevented. To save water to activate the By eliminating food waste in a certain period of time and reusing leachate to solve the leachate problem, by treating food waste continuously in the same system, shortening the processing time, eliminating the subsequent process for residue treatment, pre-blocking leachate ocean dumping, It is an object of the present invention to provide a food waste treatment apparatus and a method for extinguishing food waste using the same to prevent odor generated in the composting process of the existing method in advance.

Means of the present invention for achieving the above object is a food waste processing tank having an excipient, a collection chamber in which an extinction agent and food waste are collected; A stirrer installed in a collection chamber of the food waste treatment tank and repeatedly stirring the excipient, the extinguishing agent and the food waste a plurality of times; An excipient collected in the interior space of the collection chamber and an air blower for supplying air to the extinguishing agent and food waste through an air inlet hole spaced through the food waste treatment tank; The leachate treatment tank, which is buried in the ground while being coupled to the bottom surface of the food waste treatment tank, collects the leachate of the food waste dropped through the leachate discharge hole formed at intervals in the vertical direction at the bottom of the food waste treatment tank. Wow; An aeration unit installed in an inner space of the leachate treatment tank and supplying air to the leachate of the food waste; It is composed of a purified water supply member for penetrating through the food waste treatment tank and the leachate treatment tank and supply the purified water stored in the leachate treatment tank to the dried excipient is completed,

The agitator divides the collection chamber of the food waste treatment tank into a plurality of sections, and moves the excipient, the extinction agent, and the food waste while moving at regular intervals.

The food waste treatment apparatus and the food waste extinction method using the same according to the present invention divide the collection chamber of the food waste treatment tank into a plurality of sections, and excipients, an extinction agent and a newly added while sequentially moving each section by a predetermined period and The food waste can be agitated to be extinguished, and the leachate of the food waste is stored and purified separately, and then supplied to the excipients, extinguishing agents, and food wastes that have been extinguished to activate the extinction agent. The reduction rate and deodorization rate can be increased, and food waste is almost disappeared while preventing secondary pollution and odor occurrence by leachate, and the problem of residue treatment after food waste disposal in the existing method is solved, and leachate can be reused by reusing leachate. No speculation, no evil It has the advantage that you can solve the problem of the occurrence. In other words, by disposing of food waste within a minimum period of time and reusing leachate, the process is continuously operated. Thus, there is an effect of resolving the remaining residues after the disposal of food waste, odor problems, and leachate problems.

In addition, it can reduce post-treatment costs due to the extinction of food wastes while maximizing the efficiency of food waste disposal and operating costs by reducing initial facility investment costs, and by eliminating the composting process. Low waste, shorter processing time than composting method, shorter food waste disposal period, faster repetitive extinction treatment, large volume of food waste disposal, energy saving compared to the cost of incineration facilities, and low carbon emissions There is an effect that can protect.
