Description

Polluted Soil Cultivation Apparatus

The present invention relates to a contaminated soil tillage device, and more particularly, to be coupled to an equipment such as an excavator and configured to rotate separately after agitating wings dispersing contaminated soil vertically and horizontally, respectively, so as to uniformly distribute contaminated soil. Soil can be supplied evenly enough oxygen in the ground, minimize the cultivation period by rapid work progress, polluted soil cultivation to maximize the purification efficiency of contaminated soil by stirring while spreading microorganism and nutrient solution evenly in the ground Relates to a device.

In general, environmental problems are not just a matter of a specific region or a country, but are emerging as a global issue. So, many countries, especially developed countries, have enacted and implemented various laws and regulations to prevent soil pollution. Various methods are being implemented for the investigation and restoration of oil, and Korea also stores or handles oil from soil pollution-causing facilities (gas stations, oil depots, oil / drainage facilities, factories, military units, etc.) through the Soil Environment Conservation Act and its subordinate laws. Facilities) and pollutants are continuously monitored and managed.

As a result of the soil contamination survey recently conducted in connection with the relocation of USFK, the interest in soil purification is increasing due to serious leakage of oil storage facilities and contamination by heavy metal oil or heavy metal in the shooting range.

Such soil pollution causes the destruction of the ecosystem because the flora and fauna does not grow normally, and if left unattended, the soil is contaminated due to the widespread spread of soil such as groundwater, which causes great harm to humans along with the growth of soil crops. Treatment methods through various purification techniques to deal with this have been implemented.

Here, looking at the method of purification technology to treat the contaminated soil, in-situ treatment method for treating the contaminated soil directly from the original site in the pollution site, and ex-situ to raise the ground to treat the pollutant. The method of purification through soil cultivation, which induces biodegradation of pollutants in aerobic conditions by stirring contaminated soil, is widely used.

As such, the soil cultivation method is a method of excavating contaminated soil to an earthquake-resistant surface, transporting it, laying it down, and inverting it regularly to maintain proper moisture and supplying air, thereby promoting aerobic biodegradation process by soil microorganisms.

As described above, in relation to the technical method for tilling contaminated soil, Korean Patent No. 10-0909866 discloses a device for tilling to restore contaminated soil laid at a predetermined height in a tilling area of a bottom of a tillage area. Rail devices are installed in the longitudinal direction of the tilling area on both sides of the; Traveling saddles mounted on both rail devices; A saddle conveying device for conveying the traveling saddle; A spanning rotary device disposed in a direction traversing the traveling saddles on both sides so as to be rotatably installed on the traveling saddles, and overturning the contaminated soil by the rotation of the traveling saddles; A spanning rotary driving device installed in the traveling saddle to rotationally drive the spanning rotary device; The saddle conveying apparatus may include a plurality of wheels rotatably installed at a lower portion of the traveling saddle and seated on the rail device and mounted on one side of the traveling saddle, and a wheel drive configured to rotate the one or more wheels.
