Performance of a full scale Fenton reactor used to remove phenol in a plant valorization of waste from pulp and paper industry

Abstract

This paper show the performance of a full scale Fenton reactor used to phenol removal in a plant valorization of waste from pulp and paper industry. The effluent consists in vegetal oil and phenol. The treatment plant is designed to treat 4 m3 h-1 and is constituted by a pre-treatment to oil removal, Fenton reactor and extended aeration tank. For the evaluation of the treatment plant, it was considerate the internal and external analysis of the effluent. The overall efficiency of phenol removal is higher than 99,70 %. It was demonstrated that the combination between biological and advanced oxidative process is one interesting arranged in order to removal recalcitrant contaminants.
