The invention discloses a restoring method of soil polluted by organic substances. The method comprises the following steps that S1, water is used for spraying the soil which needs to be restored andis polluted by organic substances, and the soil is made into the slurry state; S2, the slurry obtained in S1 is pressed into thin layer slurry with the uniform thickness; S3, electron beams are adopted for irradiating the thin layer slurry; S4, organic substance pollution detection is performed on the thin layer slurry sample obtained after irradiation in S3, if the detection result is unqualified, S3 is executed, and then the thin layer slurry is irradiated. According to the restoring method of the soil polluted by organic substances, electron beams are used for irradiating to achieve soil restoring, and the technology is simple, efficient, safe, reliable, environmentally friendly, capable of achieving low-consumption treatment of high-concentration refractory toxic organic pollutants andavoiding the problem of secondary pollution, and capable of being applied to degrading DDT, halocarbons, phenols, alcohols, polymers, multi-benzene-ring aromatic compounds, pesticide residues and thelike.
Description
technical field [0001] The invention relates to the technical field of soil remediation, in particular to a method for remediating organic-contaminated soil. Background technique [0002] Soil organic pollution refers to the soil pollution caused by the organic matter entering the soil exceeding the self-purification capacity of the soil. The soil environment is one of the basic elements of the ecosystem and the basis for the survival and development of human beings and organisms. The soil environment not only directly affects the development of the national economy and the safety of land resources and the environment, but also affects the safety of agricultural products and human health. The overall situation of soil pollution in my country is quite severe, and soil organic pollution mainly comes from various pollutants produced by industrial and mining enterprises. [0003] At present, heat treatment technology is the main physical remediation technology applied to soil o...
