Study on the Application Efficiency of UV-Fenton Reagent in Treatment of Fe-Mn-Mine Wastewater

Guo Jundan

Abstract

The Fe-Mn-mine wastewater is treated by UV-Fenton reagent and the effecting factors such as pH,the dosage of H2O2,the reaction temperature and illumination time are discussed. The results show that UV-Fenton reagent performs well in treatment of Fe-Mn-mine wastewater,moreover,under the condition of that pH is 5. 5,the dosage of H2O2 is 8 mmol/L,the reaction temperature is 30℃ and the illumination time is 5 min,the best removal efficiency of Fe-Mn mine wastewater reaches up to 93% .
