UV-Fenton处理弹药废水的研究

Research on Wastewater of Explosives by UV-catalyzed Fenton Treatment

研究了自制UV-Fenton反应装置对实际TNT废水的处理效果,并对处理机理作了初步分析.实验确定了最佳条件:H2O2(30%)=3.33 mL/L、FeSO4(浓度为0.5 mol/L)=1.67 mL/L、pH为3.00、反应时间2 h、温度40℃.此条件下废水CODCr和TNT去除率可达93%以上.

Study was made on the treating effect of real TNT waste water by self-made reaction system of UV-Fenton, and initial analysis was made on the mechanism of treatment. The optimal operating conditions are as following： H2O2 （30%）=3. 33 mL/L,FeSO4 （viscosity=0. 5 mol/L）=1.67 mL/L,40℃ and 2 h at pH=3. Under these conditions,the CODCr and TNT removals are over 93%.
