铁锰矿井废水处理中紫外光-芬顿试剂的应用效能研究

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

使用紫外光-芬顿试剂对铁锰矿井水进行处理。考察了pH值、H2O2投加量、反应温度、光照时间对紫外光-芬顿试剂处理铁锰矿井废水的影响。结果表明:紫外光-芬顿试剂对铁锰矿井水的处理有良好的处理效果,当pH值为5.5,H2O2的投加量为8mmol/L,反应温度30℃,光照时间为5min时候,Mn2+的去除效率可以达到93%。

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% .
