Description:
In the present work, the treatment of a leachate from Fez city urban sanitary landfill (Morocco) was evaluated using different advanced oxidation processes (AOPs), such as, Fenton (Fe 2+ /H 2 O 2 ), photo-Fenton (Fe 2+ /H 2 O 2 /UV-A), UV-A and UV-A/H 2 O 2 . The leachate was characterized by high chemical oxygen demand (COD), low biodegradability and intense dark color. The treatment efficiency was evaluated as a function of different operation variables ([H 2 O 2 ], [Fe 2+ ], UV-A irradiance), resulting in COD removals between 30% and 77%. Removal efficiencies decreased in the following order: photo-Fenton〉 Fenton〉 UV-A/H 2 O 2 〉 UV-A. Thus, a detailed experimental analysis was carried out to analyze the effect of hydrogen peroxide and iron concentration in the photo-Fenton process. It was observed that: (a) COD removal ranged from 4% to 84% depending o...
