This invention relates to a method and system for treating interface contaminants in a mixing and clarification tank, belonging to the field of nuclear fuel reprocessing. The method involves conveying interface contaminants to the final stage mixing and clarification tank via top-tank operation, separating the organic phase, and then returning the liquid containing interface contaminants from the final stage mixing and clarification tank to the organic phase inlet of the first stage mixing and clarification tank. The interface contaminants are dispersed by the agitation of the pump impeller within the mixing and clarification tank, thereby redissolving radioactive materials in the liquid. This invention utilizes in-situ treatment of interface contaminants and recovery of radioactive elements in a mixing and clarification tank, significantly reducing the accumulation of radioactivity in interface contaminants, mitigating radiation damage from organic solvents, and is simple to operate without requiring additional treatment equipment.
