Description

Automatic land-farming apparatus for remediation of contaminated soil}

The present invention relates to a device for cultivating contaminated soil and restoring it into a physical and biological complex mechanism. More particularly, the present invention relates to a device capable of automatically arranging contaminated soil while moving along rails without using equipment such as an excavator. It is extremely easy to work, and in the span, it can evenly spread deep into the soil, supplying enough oxygen evenly, activating the growth and activity of microorganisms, maximizing the restoration efficiency, and greatly reducing the restoration period. The present invention relates to an automatic tillage device for restoring contaminated soil, which can reduce material costs and heating costs, thereby further developing the contaminated soil tillage technology.

Leaks from storage or handling oil, such as gas stations, oil depots, oil and gas distribution facilities, and military units, flow through underground veins, as well as surrounding soil, to destroy soil ecosystems in a wide range of areas and contaminate groundwater. It causes great harm to growth and human beings.

Among the methods for restoring such contaminated soils, land-farming methods using microorganisms having the ability to decompose contaminants such as oil are known. The soil cultivation method is a method of placing a well in a contaminated soil, injecting a chemical solution through an injecting well, and spreading it to an underground contaminated part to purify and restore it, or to purge and wash underground contaminated water and soil. Unlike this, the contaminated soil is excavated, spread to the ground, transferred to a cultivation site on a separate site, and mechanically tilled to activate the metabolism of microorganisms.

As shown in FIG. 11, the soil for cultivating contaminated soil is laid on the floor with a contaminated soil 2 at a height of about 30 to 100 cm, a width of about 10 to 20 m, and a length of about 100 meters. It consists of several farming cultivation fields covering 10 tillage houses (mostly made up of vinyl houses and lightweight steel structures, etc.).

While maintaining the inside of the cultivated house 10 at an appropriate temperature, the microorganisms having oil-decomposing ability and the chemical liquid containing water and nutrients necessary for the growth growth are sprayed on the contaminated soil. Crushed and crushed, hereinafter referred to as `` span '' to allow indigenous or cultured microorganisms to spread evenly throughout the soil, and supply enough oxygen to promote the metabolism of microorganisms to decompose pollutants in the soil do.

However, in the conventional tillage method, the conventional equipment such as construction excavators and farm tractors can be used without conventional equipment for spanning the contaminated soil, and can be turned upside down by traveling around a large area 10 to 20 meters wide and 100 meters long. Because it is inevitable, it takes too much time and it is difficult to evenly overturn the contaminated soil.

In addition, when using traditional equipment such as excavators, it is difficult to mix the contaminated soil evenly and evenly.In addition, the place where the wheel passes by the weight of the equipment becomes more compact, so that even if it is turned over, the liquid and oxygen Does not evenly penetrate into the soil, thereby reducing the chance of contact between microorganisms and contaminants and reducing the growth of microorganisms. Therefore, it is necessary to excessively repeat the spraying and spanning of the chemical solution, and the restoration period is excessive, which may be several times longer than the initial expected restoration period.

In addition, expensive equipment, such as excavators, must be continuously rented throughout the restoration period, and a lot of manpower, equipment, and fuel must be invested in the economy, and the longer the restoration period, the more the expenditures to be invested have to be increased exponentially. In addition, there is a disadvantage in that a separate manpower is required even when spraying the chemical liquid.

In addition, the inside of the tillage house should always maintain the proper temperature in order to activate microbial activity, but because the height of the tillage house must be increased to secure the free working space of the excavator, the space inside the tillage house becomes too large, causing a lot of temperature loss. There is a disadvantage in that the heating cost burden is increased, and the cultivation house installation cost is also required.

The present invention was developed to solve the above-mentioned conventional problems, the cultivator moves along the rails to automatically grind the contaminated soil and evenly upset the soil, so that the chemical liquid is evenly supplied and oxygen is supplied enough to restore efficiency.
