In general, environmental pollution can be classified into air pollution, water pollution, and soil pollution. Among them, soil pollution poses a serious threat to food production, and also pollutes the groundwater as well as groundwater pollution. Contaminated soil is required for early purification treatment.

In recent years, soil pollution in Korea is mainly caused by unauthorized landfill or leakage of liquid wastes. In addition, it is caused by the underground diffusion of ground - level objects left in the course of long - term industrial activities. It is caused by several kinds of chemical species rather than single species compounds. Typical complex soil pollution occurs in most industrial activity areas in the form of oil and heavy metals.

Methods for recovering contaminated soil can be classified into physical methods such as soil washing, incineration, solidification, stabilization and solvent extraction, and biological methods such as soil cultivation, composting, bio-venting, and plant restoration. Among these methods, it is relatively easy to recover soil contaminated easily and is a soil washing method.

The contaminated soil washing method is a technique of using a proper detergent to weaken the surface tension of the harmful organic pollutants bonded to the soil particles or to separate them from the soil particles by changing the heavy metal to liquid, And can be applied regardless of the kind of the pollutant.

The soil washing method is divided into the in-situ method and the ex-situ method. In-situ method does not excavate the contaminated soil, but the washing solution injecting solution, the washing solution discharging solution, the washing effluent treatment solution, Soil flushing is a soil flushing method in which contaminated soil is treated by circulating a cleaning agent in a contaminated soil to be treated on a contaminated site. Soil flushing is a long process time, So the soil washing method is mainly applied to the Ex-situ method.

The Ex-situ method is used to determine the distribution of pollutants in the soil and the physical / chemical characteristics of the soil, excavate the contaminated soil to be treated, and then use the appropriate detergent to remove the contaminated soil As a method of washing, it is used as a recently generalized soil washing method.
