FIELD: treatment of industrial sewage water to remove organic peroxides at industrial sewage works of phenol and acetone production enterprises, and at enterprises of chemical and petrochemical industries. SUBSTANCE: method for treatment of sewage water to remove organic peroxides includes decomposition of peroxides in the presence of catalyst based on manganese oxides at temperature of 65-95 C, pH 12 for 15-20 min. Method is also useful in decomposition of water-soluble hydroperoxides, perethers and peracids. EFFECT: lower production costs with increased efficiency.
