Energy-saving efficient thermal desorption remediation method for organic contaminated soil

The invention discloses an energy-saving efficient thermal desorption remediation method for organic contaminated soil. The method specifically comprises the steps that the organic contaminated soil is cleaned and dug and then placed in a closed inflatable pretreatment workshop for use; a soil crushing and screening system arranged in the remediation device is used for crushing and screening; the polluted soil is enabled to enter a feeding system to be weighed and then is conveyed into an efficient pretreatment system to be evenly mixed, dried and preheated, the polluted soil is heated in a rotary kiln thermal desorption system, organic pollutants are desorbed from the soil to obtain clean soil and tail gas, and the clean soil is enabled to enter a cooling system to be cooled and then is sent out from a discharging system; tail gas is enabled to enter firstly a cyclone dust collector for preliminary dust removal and then enter a high-temperature oxidation system for high-temperature oxidation to obtain clean
