The invention provides a thermal desorption remediation treatment method for organic matter contaminated soil. The method comprises the following steps: inputting the organic matter contaminated soilinto a pretreatment tank for pretreatment, controlling a conveying capacity according to an input quantity set by a thermal desorption chamber and conveying the soil into a thermal desorption treatment chamber; performing thermal desorption treatment, wherein negative pressure treatment chambers sequentially comprise a low-temperature negative pressure treatment chamber, a medium-temperature negative pressure treatment chamber and a high-temperature negative pressure treatment chamber; performing spraying treatment on the processed soil through a spraying chamber, cooling at the same time andthen inputting the soil into a discharging pool; allowing waste gas generated by the thermal desorption treatment chamber to enters a tail gas treatment system, degrading organic matter in the waste gas through a high-temperat
