Background
With the rapid development of industry and agriculture and the urbanization construction of villages, the problems of inorganic pollution and organic pollution of soil in China are becoming more serious, and the soil pollution area is also increasing year by year. The inorganic pollutants mainly comprise heavy metals such as cadmium, mercury, lead, chromium, zinc and the like and non-metals such as arsenic and the like; the organic pollutants mainly comprise benzopyrenes, organic pesticides and the like. Soil is an important component of the ecological environment and is a repository for the biogeochemical cycle of matter. The soil pollution problem in China is serious, and the remediation and treatment of the polluted soil are not negligible.
The soil leaching refers to a process of injecting or permeating flushing liquid into the soil, enabling the flushing liquid to flow through a soil layer to be treated, resolving pollutants in the soil, and then treating and recycling the flushing liquid containing the pollutants.
The mechanisms by which soil holds metals can be divided into two broad categories: firstly, the ionic adsorption is carried out on the surface of the soil component; secondly, the formation of a precipitate of metal compounds. The principle of soil leaching is to use the action of a reagent and heavy metal in the solid phase of soil to form soluble heavy metal ions or metal complexes, then use clear water to flush pollutants outside the root layer, and then use a compound containing a certain ligand to leach the soil to form more stable complexes with the heavy metal ions. The leacheate can be water, a chemical solvent, or other fluid that may leach contaminants from the soil. The injection of the leacheate can change the adsorption-desorption characteristics, oxidation-reduction potential, interfacial tension, pH value, distribution, dissolution, precipitation states and the like of the soil and the pollutants, so that the solubility of the pollutants is increased, the pollutants and the solution form emulsion or are subjected to chemical reaction, and the pollutants in the soil are removed.
The existing leaching experimental device can not flexibly adjust the usage amount of experimental soil, the spraying speed of the leacheate and the usage amount of the leacheate.
