Abstract: In order to promote the reduction and phase-out of perfluorooctane sulfonic acid, its salts and perfluorooctane sulfonyl fluoride(PFOS/PFOSF), and prevent and control environmental risks, it is urgent to carry out safe and harmless treatment of the products and by-products containing PFOS/PFOSF and wastes containing PFOS/PFOSF produced during production and use. Through investigation and data analysis, the result shows that China has stopped production of PFOSF in 2021 and the total production of PFOS/PFOSF duringin 2002- ~ 2020 is about 2120 t. Typical liquid wastes containing PFOS/PFOSF in China include waste firefighting foam, residual liquid collected after use of firefighting foam, waste electroplating solution, process or cleaning wastewater, waste organic solvent, etc. Solid/semisolid wastes include distilling(rectification) still residue, waste water treatment sludge, contaminated soil, electroplating filter residue, waste adsorbent and filter material, etc. At present, the feasible PFOS/PFOSF non-destructive treatment technologies for liquid wastes mainly include activated carbon and resin adsorption, membrane filtration and coagulation, and the feasible PFOS/PFOSF destructed treatment technologies include incineration/cement kiln, ultrasonic degradation and sub/supercritical water treatment, but they all have certain precondition in application. For solid/semisolid wastes, feasible PFOS/PFOSF non-destructive treatment technologies include stabilization and landfill, while incineration/cement kiln is currently the most feasible PFOS/PFOSF destructed treatment technology. It is suggested to adopt appropriate treatment and disposal technologies according to the characteristics of typical PFOS/PFOSF wastes in China, while applying mature technologies, try to adopt sub/supercritical water treatment technology, ultrasonic degradation technology and other relatively new technologies. Wastes with PFOS/PFOSF content ≥50 mg/kg should be disposed of by the PFOS/PFOSF destructed treatment technologies, and wastes with PFOS/PFOSF content <50 mg/kg can be put into landfill after stabilization pretreatment.
