The invention discloses a soil remediation method and a remediation agent and application thereof, and belongs to the technical field of soil remediation, the soil remediation method is based on a multiphase extraction system, comprises the step of injecting the remediation agent into soil to be remediated, and is characterized in that the remediation agent is cardanol polyoxyethylene ether and trehalose lipid. According to the soil remediation method, on the basis of the multi-phase extraction technology, the remediation agent composed of the specific surfactant is injected into the soil, organic pollutants can be effectively removed, the soil remediation effect is enhanced, and the purposes of shortening the remediation time and reducing energy consumption are achieved. And the remediation agent is low in toxicity, good in biodegradability and free of secondary pollution. 本发明公开了一种土壤修复方法及其修复药剂和应用，属于土壤修复技术领域，所述的土壤修复方法，基于多相抽提系统，包括向待修复土壤中注入修复药剂的步骤，其特征在于，所述修复药剂为腰果酚聚氧乙烯醚和海藻糖脂。本发明的土壤修复方法，基于多相抽提技术，通过向土壤中注入特定的表面活性剂组
