The invention provides a purification system for persistent organic pollutants, such as polychlorinated biphenyls (PCBs), poly brominated diphenyl ethers (PBDESs) and chlorinated paraffins (CPs), in environmental solid media and a treatment method of the purification system. The purification system comprises a first extraction device, a first concentration device, a separation and purification device and a second concentration device which are arranged in sequence. The separation and purification device comprises a chromatographic column device and an automatic collection device. The automaticcollection device is located below the chromatographic column device. A composite column is arranged in the chromatographic column device. A purification layer and a dispersion layer are arranged inthe composite column. The purification layer is located above the dispersion layer. The purification system and the treatment method thereof have the advantages that the devices in the system interactwith each other; by the co
