Abstract

Fenton process and photo-Fenton process were employed to treat the wastewater formed during the recovery of RDX. The effects of Fe₂SO₄ dosage, H₂O₂ dosage, pH, reaction time and temperature on removal efficiency of chemical oxygen demand (COD) the wastewater were investigated. The results show that the optimum FeSO₄ dosage and pH value are 700 mg/L and 2.5, respectively, and that the COD removal efficiency of the wastewater increases with the rise of H₂O₂ dosage but decreases with the rise of temperature. Under the conditions with H₂O₂ dosage of 100 mg/L and the reaction temperature of 15°C, the best removal efficiency of COD is obtained at 82.07%. In the photo-Fenton process, FeSO₄ dosage could be reduced sharply to 50 mg/L.
