The invention discloses a repairing and resourceful treatment method of contaminated soil. The repairing and resourceful treatment method comprises the steps of controlling the particle size of the contaminated soil to be 80 meshes or below, adding sludge, wood powder, and water in certain proportion into the soil, mixing the materials to prepare a raw blank in a prilling disk, adjusting moisture, afterwards sending the raw blank into a rotary kilin to be subjected to roasting treatment, tail gas treatment, industrial water treatment and the like. Through the adoption of the repairing and resource treatment method to treat the soil which is contaminated by polycyclic aromatic hydrocarbons, not only the purpose of repairing the soil is achieved, problem of application orientation of the repaired soil is also solved, and the prepared ceramsite can directly create economic benefits. 本发明公开了种污染土壤的修复与资源化处置方法，所述方法包括：控制污染土壤粒径在80目以下、加入定比例的污泥、木粉、水，混合、在成球盘中制备生坯、调节水分后送入回转窑中焙烧处理、尾气处置、生产废水处置等步骤。采用本发明的方法处置多环芳烃污染土壤，不但可以达到土壤进
