The invention discloses a separation device and method for aged micro-plastics, and relates to the technical field of solid waste treatment. The separation device comprises an elution column, a gate valve I, a gate valve II and a stirring paddle, wherein a cleaning liquid inlet is formed in the top of the elution column, an eluent inlet, a water outlet and the stirring paddle are arranged at the lower portion of the elution column, and the distance between the gate valve I and the gate valve II is no less than one third of the length of the elution column. Furthermore, the invention provides the separation method. Micro-plastic particles with different aging degrees are separated through eluents with different polarities, and meanwhile, elution separation can be carried out according to different aging degrees of different types of micro-plastics by adjusting the types of the eluents. According to the separation device and method, the blank of existing micro-plastic separation technology is filled up, and mea
