Study of Nitrobenzene Wastewater Treatment by Three-Dimensional Electrode Method

In this paper studies are made on the oxidation capacity of three-dimensional electrode method in treating non-degradable wastewater organic pollutant of nitrobenzene,and we aim to make sure the technological conditions of applying three-dimensional electrode method in nitrobenzene containing wastewater.Using the nitrobenzene water as the sample made in lab and adopting a self-made photo-reactor we analyze the effects of reaction condition such as pH,Nitrobenzene concentration input,voltages,reaction time,and electrolyte adding to treat nitrobenzene wastewater by three-dimensional electrode method.The research result shows that three-dimensional electrode method has a high decrease rate,and reaction rate and the decrease rate of nitrobenzene can reach 89.21%.The dosage of pH,Nitrobenzene concentration input,voltages,reaction time,and electrolyte adding exercise greatly influence treatment effect.When the concentration of nitrobenzene is 250 mg/L,Na2SO4 electrolyte adding is 1 g,three-dimensional electrode method has a good effect on disposing nitrobenzene,the optimum reaction conditions are as follows:pH is about 3,voltages is 5 V,reaction time is 45 min,pole distance is 5 cm.
