PROCESS FOR THE TREATMENT OF PHENOLATED INDUSTRIAL EFFLUENT

摘要

The present invention relates to a process for the complete purification of industrial effluent polluted by phenolated impurities wherein the degradation of the polluant is obtained by the action of an oxidizing reagent containing the HSO5<-> anion. The oxidizing reagent is a member of the group constituted by monopersulphuric acid and its salts. The oxidizing reagent is an aqueous solution containing HSO5 <-> anion and containing furthermore NH4<+>, HSO4<-> ions and, optionally, alkaline cations. The oxidizing reagent is an aqueous solution containing the HSO5<-> anion and containing furthermore hydrogen peroxide and H<+>, HSO4<-> and SO4<-> ions.
