Abstract

Effluents containing hazardous or recalcitrant organic substances are generated in a wide variety of industrial processes. The inadequate management of these effluents can cause contamination of underground and surface water. Their treatment by conventional processes may not be technically efficient, and usually prevents effluents from being discarded or reused in industrial processing units. For the study, the Fenton and Photo-Fenton process Will be considered, with of utilizing UV light as a photon source to the process. Oxidative process will be optimized with a fractional factorial design (23-1) with triplicate at the midpoint and random duplicates, where the input variables were: H2O2, Fe2+, pH and UV light. The treatment system in bench scale will utilize a batch reactor with recycle, with a volume of 2 L and 90 minutes of reaction. After the Fenton and Photo-Fenton process, the sample of the Best experiment will be treat by biological process in order to verify the efficiency of degradation of the organic matter of the effluent studied.
