Study on Treatment to Methanol Wastewater by UV/Fenton

Abstract:

In this paper, aqueous methanol (methanol concentration 1000 mg·l^-1) degradation was studied by using UV/Fenton, and effect of methanol degradation was evaluated with COD removal rate. When pH was determined, H₂O₂ dosage, Fe²⁺ dosage and reaction time were investigated by single factor test, respectively. In the orthogonal experiment, UV/Fenton was used to deal with wastewater of 1000 mg·l^-1methanol, the order of the influent factors on COD removal was: H₂O₂ dosage > reaction time > Fe²⁺ content. Under the optimal condition (6%H₂O₂50 ml·l^-1, Fe²⁺ 0.9 g·l^-1, reaction time 60 min), 95.77% COD removal rate was obtained. In addition, a comparison of UV, Fenton regent and UV/Fenton system indicated that UV and Fe²⁺ had synergistic effect on catalytic decomposition of H₂O₂, and reaction time to obtain the highest COD removal was shorted 10 min when UV/Fenton was used.
