Problems solved by technology
[0003] The current soil thermal desorption restoration methods on the market are too traditional in the implementation process. In the restoration process, the overall treatment and restoration method is adopted. Such restoration methods have low efficiency, due to the composition of soil particles. The size is different, so it is often necessary to carry out multiple treatment and repair work on the mixed soil, which is very troublesome when repairing

The invention discloses an in-situ and ex-situ thermal desorption remediation system and method for organic contaminated soil. According to the method, a brand new polluted soil adsorption mode is adopted, the soil is crushed in the treatment process, large-particle soil and small-particle soil are distinguished, then the large-particle soil and the small-particle soil are repaired in a targeted mode, the large-particle soil only needs to be washed, the small-particle soil only needs to be washed, and the large-particle soil only needs to be washed; and small-particle soil adopts a thermal desorption remediation mode, so that the soil can be backfilled again after all treatment work is completed, the treatment efficiency is greatly improved during remediation, treatment and remediation can be performed in a targeted manner, and the method is very convenient to implement and has a wide application prospect.
Description
technical field [0001] The invention relates to the technical field of soil remediation, in particular to an in-situ thermal desorption remediation system and method for organic polluted soil. Background technique [0002] Soil remediation is a technical measure to restore the polluted soil to normal functions. In the soil remediation industry, there are more than 100 soil remediation technologies, and there are more than 10 commonly used technologies, which can be roughly divided into three types: physical, chemical and biological. The goal is to restore the normal function of the soil. Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentrations to acceptable levels, or to reduce toxic and harmful pollutants. Pollutants are converted into harmless substances. [0003] The current soil thermal desorption remediation methods on the market are too traditional i...
