Study on the Treatment of Cutting Fluid Wastewater Chromaticity by Multiphase Fenton System
2021
The composition of the cutting fluid wastewater is complex, the chromaticity is high, the liquid is grayish white, and the visibility is poor. In this research work, it used a multiphase Fenton system composed of catalysts CuO/CeO2 and H2O2 to treat the organic wastewater chromaticity, and various influencing factors were studied. The optimal conditions of the experiment would be: The dosage of the catalyst was 1.6 g/L, the dosage of H2O2 was 0.5 mol/L, the reaction time was 180 min, the initial pH was 8, and the reaction temperature was 25 °C. At this time, the removal efficiency of chromaticity could reach 70%.
