چکیده

The use of AOPs (Advanced Oxidation Processes) for the treatment of industrial wastewaters has increased during the last years. The process efficiency depends on the treatment conditions (temperature, pH, reagent dosage etc.) and it is very difficult to predict it because the reaction mechanisms are strongly affected by the mutual relationship among these parameters and the wastewater composition. During this work three AOPs (Fenton, photo-Fenton, H2O2/UV) were studied. They were used for the treatment of a real wastewater (deriving from a chemical-pharmaceutical factory) under different conditions in a lab scale plant. Data analysis was aimed to understand the main reaction characteristics, so as to assess the suitable process and the proper treatment conditions.
