Treatment of aqueous compositions, especially effluent waters contaminated with organic substances, uses electrochemical decomposition with applied ultrasound

摘要

Use of a combination of electrochemical treatment and ultrasound in the destruction of organic contaminants in an aqueous medium. Process for electrochemical treatment of an aqueous composition containing one or more organic substances by means of an electrochemical reactor comprising an anode compartment and a cathode compartment separated by a suitable separator, the aqueous composition being introduced into the anode compartment of the reactor, the anode compartment containing a liquid support containing a suspension of electrochemically active particles, and simultaneously or successively subjecting the medium resulting from the introduction of the aqueous composition to an oxidation potential and to the action of ultrasound.
