The invention discloses a continuous remediation device for organic contaminated soil, and belongs to the technical field of organic pollutant remediation, the continuous remediation device comprises a conveyor belt arranged in a shell, the upper portion of the conveyor belt is sequentially divided into a soil feeding area, an ozone water vapor backflow area, a variable-frequency microwave thermal desorption area and a UV digestion area in the soil conveying direction, the conveyor belt is arranged in the microwave resonant cavity at the lower part of the shell; a discharging port is formed in the tail of the shell, a turnover mechanism is arranged at the bottom of the conveying belt, conveyed soil is turned over and scattered, and the retention time of the soil on the conveying belt is prolonged. In the process that soil is conveyed along with the conveying belt, the soil is sequentially subjected to ozone oxidation in the ozone water vapor backflow area, organic matter in the soil is thermally desorbed in t
