UV-Fenton试剂处理含乳化液（油）矿井水的实验

为充分发挥UV-Fenton试剂处理矿井水中的乳化液（油）的去除效果,通过正交实验和单因素实验,分析了H2O2的浓度、FeSO4的浓度、光照时间及溶液pH对去除矿井水中乳化油的影响。在综合考虑成本和去除效果的前提下,提出了反应的最佳条件：H2O2的浓度为26.43 mmol/L,FeSO4的浓度为0.2 mmol/L,pH为3,光照时间为35 min。实验结果表明,含乳化液（油）矿井水经过UV-Fenton氧化处理后,油的去除率可达到94.95%。

Experiment on treatment of emulsified liquid(oil) mine water by UV-Fenton reagent

This paper attempts to study the better use of UV-Fenton reagent to removing emulsified liquid（oil） from mine water.The study involves analyzing the impact of H2O2 concentration,FeSO4 concentration,illumination time and solution pH on removal of emulsified oil in mine water by utilizing orthogonal and single factor experiment and gives the best reaction condition,as required by the economy and the removal effect,namely the concentration of H2O2 of 26.43 mmol/L,the concentration of FeSO4 of 0.2 mmol/L,pH of 3,and the illumination time of 35 min.The results reveal that the emulsified liquid（oil） mine water treated by UV-Fenton oxidation process exhibits the oil removal rate of up to 94.95%.
