Disclosed is a method for concentrating, separating and removing a perfluorinated compound. The method comprises the following steps: an electrocoagulation step: using an electrocoagulation method to adsorb a perfluorinated compound in a water solution or a mixed solution of water and an organic solvent to the surface of a floc generated in electrocoagulation, so as to form sludge; and a centrifugation step: performing centrifugation on the sludge comprising the perfluorinated compound, so as to separate the perfluorinated compound from the sludge and generate a concentrated perfluorinated compound solution. By using the electrocoagulation method, the present invention has a simple technological process, is easy to operate, requires moderate reaction conditions, has low energy consumption and good treatment effect, is stable and reliable, and is easy for industrialized application; in addition, the centrifugal separation technology for harmless treatment of the generated sludge comprising the perfluorinated compound is novel, does not require addition of chemical reagents, realizes dehydration of the sludge while the harmless treatment is performed, requires simple devices and is easy for automatic operation. |
