Kind Code: A1 A method and apparatus for oxidatively decomposing contaminated soil containing an organochlorine pesticide are provided. The method includes S1 soil pretreatment, S2 soil washing, S3 wastewater treatment, S4 wet soil treatment, S5 detection evaluation, and the apparatus includes headstock, first hook, second hook, field Including hammer, cleaning device, photocatalyst tank, ultrasonic oxidation tank, thermal desorption device, bioremediation reagent mixing device, carriage, electromagnetic stirrer, grouting machine, water pump. The present invention rapidly removes most of the organochlorine pesticides in the soil by washing, rapidly reduces the residual organochlorine pesticides, and then removes the remaining organochlorine pesticides in the moist soil by thermal desorption. In order to remove, the removal rate of organochlorine pesticides in the soil is high, and the washed wastewater is catalytically oxidized to quickly decompose the organochlorine pesticides in the wastewater, and the purified wastewater is reused. , environmentally friendly and energy saving.
