Description

A method of soil purification using a self-contained integrated functional soil mixing system

The present invention relates to a soil purification method using a self-propelled integrated function soil mixing device, and more particularly, by moving the self-propelled integrated function soil mixing device to a site with contaminated soil, excavating the contaminated soil, and mixing it with chemicals It relates to a soil purification method using a self-propelled integrated functional soil mixing device that can efficiently purify contaminated soil by discharging it back to the road.

In general, environmental pollution is usually classified into air pollution, water pollution, and soil pollution. In particular, soil pollution may be mainly caused by unauthorized landfilling of liquid waste or leakage accidents. In addition, since it is made by underground diffusion of ground deposits left unattended in the course of long-term industrial activities, most of them occur in industrial activity areas. .

When these heavy metals accumulate in the human body, they are not excreted well, but accumulate in the proteins in our body and cause side effects over a long period of time, so it is very dangerous. For example, hemoglobin, which transports oxygen throughout our body, is in the form of iron binding to a protein called globin, but when mercury enters our body and attaches to globin instead of iron, it loses its oxygen carrying ability. In addition, lead paralyzes nerves and muscles, cadmium can cause lung cancer, weaken bones, and manganese accumulates in the brain and liver, causing stunted growth and reduced fertility. The fluidity of contaminated soil containing heavy metals depends on the combination of heavy metals, the presence of products according to changes in external conditions such as weathering, clay and water content of soil, pH of soil water, activity of microorganisms, and acid mine drainage generated in the vicinity. Because it is affected by the physical and chemical properties of the soil and the surrounding environment, such as acid mine drainage, heavy metal transfer and distribution of heavy metal-contaminated crops during the growth process of crops planted on contaminated farmland due to the fluidity of heavy metals in the contaminated soil. is emerging as a serious social problem, so there is an urgent need to take measures to restore heavy metal-contaminated soil in order to reduce the transfer damage caused by the extensive-scale contaminated soil.

As a prior art for restoring the contaminated soil, Republic of Korea Patent Publication No. 10-1629885, 'mobile contaminated soil stabilization equipment and on-site soil stabilization method using the same' has been registered. The purpose of this prior art is to provide a portable polluted soil stabilization equipment and a method for stabilizing the polluted soil in the field using the same, which can be quickly moved to the contaminated soil site through miniaturization and mobility to purify (stabilize) and reuse the contaminated soil in the field. .

However, the prior art requires separate equipment for excavating the soil to be purified and putting it in a hopper, and if there is a material such as a large stone in the contaminated soil, it is difficult to process it, and it is stable on the upper side of the soil. The mixing efficiency of the soil and the stabilizer is lowered by injecting the agent, and it is attempted to mix the soil and the stabilizer by the screw, but the screw transfers the soil rather than mixing it, so there is a problem that the mixing efficiency is also lowered.

The soil mixed with the chemicals transported by the conveyor 133 is dropped into the rotating first drum 141 and then transferred to the rear by the transfer blade, and at the same time, some of the soil is transferred to the second drum 142 through the mesh network. The soil that has fallen and has been transported to the rear may fall to the second drum 142 through the through holes. That is, the soil mixed with the chemical may be mixed better while being transported to the rear from the inside of the first drum 141 and falling to the second drum 142 at the same time.

The chemically treated soil in which the chemical and the contaminated soil are mixed may be transported to the rear of the third drum 143 and then may be discharged by falling to the collecting device 151 of the soil discharging means 150 through a through hole.

The chemically treated soil discharged to the collecting device 151 may be discharged to the ground through the distribution device 153 . At this time, it is possible to prevent the generation of dust by spraying the mist sprayed from the mist spraying device 152 on the chemically treated soil discharged to the ground.
