Özet

This study describes the treatment of preliminary aerated mineral-oil recovery industry wastewater (MORIW) using Fenton's reagent. Application parameters such as Fe(2+) and H(2)O(2) concentration, pH value, reaction period, temperature, and sludge characteristics were examined. Maximum oxidation efficiency (about 90% COD removal and 80% UV(254) removal) was achieved at the conditions of 0.003 Fe(2+):H(2)O(2) ratio, 180 min reaction period, pH 3 and 293 K temperature. The oxidation process of MORIW followed pseudo-second-order reaction kinetic. The studied sludge character has a high density with settling velocity. In addition, the high settlement rate (SR) and liquid/solid ratio (L/S) values demonstrated that the formed sludge was suitable for dewatering and drying processes.
