PROCESS AND INSTALLATION FOR THE TREATMENT OF EFFLUENTS BY OXIDATION AND DENITRIFICATION IN THE PRESENCE OF A HETEROGENEOUS CATALYST

摘要

Method and apparatus for the oxidation processing and denitrification of effluents in the presence of a heterogeneous catalyst. An aqueous phase effluent oxidation method wherein effluents are oxidised in the presence of at least one catalyst and at least one oxidising agent at a temperature between about 20 and about 350 ~C and at a total pressure between about 1 and about 160 bar to mineralise part of the organic material and the total and ammonia nitrogen in the effluent, said oxidation being carried out in a reactor in which a gas phase is provided above the liquid phase consisting of said effluents. Said catalyst is a heterogeneous catalyst arranged within the reactor above the interface between said gas phase and said liquid phase.
