摘　　要：为了提升机械加工乳化液废水处理效果,通过实验分析的方式,设计了一种基于Fenton技术的机械加工乳化液废水处理工艺。首先,根据实验需求,设计出相应的实验方案,包括实验试剂与设备的选择,实验操作方法的确定。然后以此为基础,分别实验分析了不同p H值、H_(2)O_(2)与Fe^(2+)添加摩尔比、H_(2)O_(2)添加量、反应温度、反应时间、K_(2)S_(2)O_(8)添加量条件下的机械加工乳化液废水的处理效果,进而确定出最佳的Fenton处理工艺参数。通过实验分析可知,Fenton处理工艺的最佳参数为:废水p H值为3.0,H_(2)O_(2)与Fe^(2+)添加摩尔比为3.0,H_(2)O_(2)添加量为30 m L/L,K_(2)S_(2)O_(8)添加量为4.0 g/L,反应温度为60℃,反应时间为60 min,该条件下,乳化液废水中COD去除率达到85%左右,浊度去除率达到70%左右,可将该工艺参数推广到现代机械加工乳化液废水处理工作当中。In order to improve the treatment effect of mechanical processing emulsion wastewater,a mechanical processing emulsion wastewater treatment process based on Fenton technology was designed through experimental analysis.Firstly,according to the experimental requirements,the corresponding experimental plan was designed,including the selection of experimental reagents and equipment,and the determination of experimental operation methods.Then,based on this,the treatment effect of mechanical processing emulsion wastewater was experimentally analyzed under different pH values,H_(2)O_(2) to Fe^(2+)molar ratios,H_(2)O_(2) addition amounts,reaction temperatures,reaction times,and K_(2)S_(2)O_(8) addition amounts,and the optimal Fenton treatment process parameters were determined.Through experimental analysis,it can be concluded that the optimal parameters for Fenton treatment process are:wastewater pH value of 3.0,H_(2)O_(2) to Fe^(2+)molar ratio of 3.0,H_(2)O_(2) addition amount of 30 mL/L,K_(2)S_(2)O_(8) addition amount of 4.0 g/L,reaction temperature of 60℃,and reaction time of 60 min.Under these conditions,the COD removal rate of emulsion wastewater reaches about 85%,and the turbidity removal rate reaches about 70%.This process parameter can be extended to modern mechanical processing emulsion wastewater treatment work.
