Description

[0001] SOLID WASTE PROCESSING APPARATUS [0002]

More particularly, the present invention relates to an apparatus for automatically processing a solid waste, and more particularly, to a system for automatically performing a series of processes such as supply, crushing, sorting and drying of solid waste, And more particularly, to a solid waste automatic treatment apparatus capable of easily performing agitation, crushing, sorting, and drying of solid waste.

In general, waste refers to substances that are not necessary for human life or business activities, such as waste, soft materials, sludge, waste oil, waste acid, waste alkaline, carcasses of animals.

Solid waste refers to solid state waste that is distinguished from liquid and meteorological wastes among wastes generated from all collective settlements such as cities, farms and villages. It includes municipal wastes under the Waste Management Act and is composed of municipal wastes And may include design waste at the time of discharge from the premises within the scope of not compromising the identity of the composition when integrated with the municipal wastes and the wastes of the municipal wastes.

Solid wastes include at least one of garden waste, sewage sludge, animal wastes, agricultural wastes, fish wastes, food processing wastes, beverage process wastes, incoming sanitary / paper wastes, or mixtures thereof.

The term "solid matter" refers to materials that are not considered to be wastes but which can be added to the process by applying the present process. Corrugated cardboard, newsprint, scrap paper, sawdust, agricultural and livestock products, and the like, including at least one of them or a mixture thereof.

Solid waste is considered to include both organic and inorganic materials such as food waste, paper, wood, waste plastic, waste vinyl, and waste iron. In the following, food waste, paper, and wood are classified as organic waste, waste plastic, waste vinyl, waste iron, and waste metal as inorganic waste.

Conventionally, most municipal wastes are buried or incinerated in Korea. However, when municipal solid waste containing large amounts of organic matter is buried, greenhouse gases such as methane gas and carbon dioxide are generated in the landfill due to the decomposition of organic components, and water quality deteriorates due to contamination of leachate, There is a problem that soil contamination occurs due to the landfill of decomposable substances.

Further, since the conventional landfill is already saturated, there is a problem that a new landfill site must be secured in order to keep the existing landfill method. On the other hand, municipal waste was incinerated in order to treat municipal waste. However, in the case of incineration of municipal waste, toxic substances such as dioxins and furans are discharged, causing secondary environmental pollution.

On the other hand, in order to prevent the generation of the harmful components, an alternative to install a pollution control facility has been proposed, but it has been disadvantageous in terms of economic and practical aspects. Therefore, it has been proposed to separate and collect only food waste, and then recycle it. However, there is a restriction in that the food waste must be collected and collected. In addition, even if the food waste is separated and treated, the remaining waste is buried or incinerated.

As an alternative to solving the problems of conventional landfilling and incineration, techniques for solid waste disposal have been developed, but there is much room for improvement.
