Treatment of Oily Wastewater by E-Fenton Technique

In this paper the treatment of oily wastewater E-Fenton reagent was studied.The experiment proved the order of factors affecting removal rate is:the pH,the voltage,the reaction time,the concentration of oily wastewater,and concentration of Na2SO4.The optimum operation parameters were determined by single factor analysis as follows:under the room temperature,the pH is 2.5,the voltage is 10V,the reaction time is 60 mins,the concentration of oily wastewater is 100mg/L,and concentration of Na2SO4 is 30 mg/L.Under the optimum reaction conditions,the removal rate of oil is 50.5%.
