In recent years, the world has come to pay attention to the research of the contaminated soil treatment technology. As an important technology for soil remediation, the thermal desorption technology has a great application prospect in remediation of organic-polluted soil. The thermal desorption technology can realize at least 90% removal rate of volatile organic pollutants (VOCs) and semi-volatile organic pollutants (SVOCs), has good treatment effect on oil phase (non-aqueous phase liquid), and can also repair severe soil environments (silt and cohesive soil) which cannot be adapted to other technologies such as microorganism/plant repair technology, gas phase extraction technology and the like. Therefore, compared with other restoration technologies, the thermal desorption technology has the outstanding advantages of good restoration effect, high restoration speed, wide application range, controllable secondary pollution and the like.
