Reduction of chemical oxygen demand (COD) value of petrochemical industry wastewater (COD ∼11 500 mg/L) by Fenton's oxidation has been investigated. Batch tests were conducted on the effluent samples to determine the optimum process conditions. Fenton's oxidation process was found to effectively reduce the COD by 97.5% in 100 min. Effects of different process parameters: pH, H 2 O 2 dosage, Fe 2+ dosage, H 2 O 2 /Fe 2+ ratio, temperature were investigated. The optimum conditions were at pH 3, H 2 O 2 concentration 3 M, Fe 2+ concentration 0.06 M and temperature 30°C. Optimum molar ratio [H 2 O 2 /Fe 2+ ] was 50:1. At optimum conditions, 97.5% COD reduction was achieved for the typical effluent sample from nearby industry manufacturing mainly PET resins. On a analysé la réduction de la valeur demande chimique en oxygène (DCO) des eaux usées de l'industrie pétrochimique (DCO ∼11 500 mg/L) par oxydation de Fenton. Des essais par lots ont été réalisés sur les échantillons d'effluent dans le but de déterminer les conditions de processus optimales. On a découvert que le processus d'oxydation de Fenton a réduit efficacement la DCO de 97,5% en 100 min. Les effets de différents paramètres de processus, soit pH, dose de H 2 O 2 , dose de Fe 2+ , rapport H 2 O 2 /Fe 2+ et température ont été analysés. Les conditions optimales étaient pH 3, concentration de H 2 O 2 3 M, concentration de Fe 2+ 0,06 M et température 30°C. Le rapport molaire optimal [H 2 O 2 /Fe 2+ ] était de 50:1. À des conditions optimales, on est parvenu à une réduction de DCO de 97,5% pour l'échantillon d'effluent typique de l'industrie à proximité qui fabrique principalement des résines de PET. Can. J.
