soil leaching technology originated in europe and the united states and began to be used in the 1980s and 1990s, of which japan is more widely used. soil leaching refers to the use of cleaning liquid to dissolve the heavy metals in the solid phase of the soil from the soil, desorption, reverse complexation and other effects to transfer heavy metals to the soil liquid phase, and then for the disposal of wastewater soil remediation technology.
the main technical principles of soil leaching mainly have two points: first, soil particles are divided into different particle sizes, with the reduction of soil particles, their specific surface area becomes larger, the organic matter content increases, and it is easy to adsorb heavy metals. in general, soil heavy metals are concentrated on the soil fine particles, large particles of soil relatively clean or heavy metals are easy to elution from the soil, through the screening work, the large particles of the soil separated, after washing with clean water to clean the soil, to achieve the reduction of polluted soil. second, the implementation effect of cleaning is related to the form of heavy metals in the soil, after the heavy metals enter the soil, through dissolution, precipitation, agglomeration, complexation and adsorption and other effects, the formation of different chemical forms, and then affect its activity and mobility.
In terms of land use methods, soil leaching technology is more suitable for soil used for construction land, while in terms of soil physical and chemical properties, soil leaching technology is more suitable for sandy soil than clay. The content of clay particles in the leached soil is not higher than 25 to 30%. In recent years, Desen Environment has earlier developed a skid-mounted soil leaching equipment, which specially adds an efficient soaking grading module, which can effectively prevent the precipitation of pollutants and achieve the effect of full integration of pollutants and agents, and has applied for a number of patents, and the customer usage rate has reached 100%. This set of skid-mounted soil leaching equipment can be equipped with 5G intelligent automatic control system, remote operation supervision, to ensure the smooth operation of the entire production line. Feel free to call for advice.
