摘要： The present invention relates to a process for destroying per- and polyfluoroalkyl substances in an aqueous effluent by electro-oxidation comprising:
concentrating the per- and polyfluoroalkyl substances using a filtration or sorbent technology;
washing the filter or sorbent with a regenerant to generate a spent regenerant containing the per- and polyfluoroalkyl substances;
providing an electrolytic cell with an anode electrode and a cathode electrode; and
contacting said regenerant with the anode electrode and the cathode electrode while a current of between 0.5 mA/cm2 and 1 mA/ cm2 flows between said electrodes, thereby destroying the per- and polyfluoroalkyl substances by means of electro-oxidation.-
