三维电催化氧化处理苯胺废水

Three-dimensional electrocatalytic oxidation treatment of aniline wastewater

为研究三维电催化氧化对苯胺有机污染物的处理效果,在反应槽中投加柱状活性炭后,运用三维电催化氧化反应器,探讨了外加电压、初始pH、粒子电极投加量及Cl-浓度对苯胺去除效果的影响。结果表明:在电压5V,初始pH=4,粒子电极投加质量为100g,c(Cl^-)为0.08mol/L,反应时间达到150min的条件下,苯胺的去除率最高,为98.2%。对降解过程中各时刻的浓度进行拟合,近似符合一级动力学方程。

In this paper,the effect of three-dimensional electrocatalytic oxidation on the treatment of organic pollutants of aniline was studied.After the columnar activated carbon was added to the reaction tank,the effects of applied voltage,initial pH,particle electrode dosage and Cl—concentration on the removal of aniline were investigated by using a three—dimensional electrocatalytic oxidation reactor.The results showed that the removal rate of aniline was the highest at the voltage of 5v,the initial pH=4,the mass of the particle electrode was 1OOg,the c(Cl^-)was 0.08mol/L,and the reaction time was 150min.The concentration at each moment in the degradation process is fitted to approximate the first—order kinetic equation.
