  • 摘要: 以毡状活性炭纤维为阳极,不锈钢为阴极,吸附-电化学氧化耦合降解对氯苯酚废水进行了研究。考察了吸附或耦合电化学氧化过程、电流密度、支持电解质硫酸钠浓度和活性炭纤维重复使用对废水COD去除率的影响,结果表明,采用吸附-电化学氧化耦合方法,当电流密度7.6 mA/cm2 支持电解质(硫酸钠)浓度为1 g/L,处理时间为180 min,4-CP废水COD去除率可达97.09%。毡状活性炭纤维对4-CP的静态吸附过程符合Langmiu吸附等温方程。建立了吸附-电化学氧化COD去除动力学模型,动力学模型参数表明, 对于COD的去除,电化学氧化作用比吸附作用大。
    Abstract: The p-chlorophenol(4-CP)wastewater treatment by coupling adsorption with electrochemical oxidation degradation was investigated, using felty activated carbon fiber as positive electrode and stainless steel as negative electrode. The influences of adsorption or coupled with electrochemical oxidation process,current density,supporting electrolyte(Na2SO4)concentration and reusing of activated carbon fiber on the removal of chemical oxygen demand (COD) were studied. Base on the method of coupling adsorption with electrochemical oxidation degradation, under the following conditions: current density of 7.6 mA/cm2, supporting electrolyte (Na2SO4) of 1 g/L,reaction time of 180 min, the removal of COD was about 97.09%.The adsorption equilibrium of 4-CP onto activated carbon fiber was coincident with the Langermiu isotherm equilibrium. A kinetic model for COD removal was established based on the adsorption and electrochemical oxidation process. The parameters predicted from the kinetic model showed that electrochemical oxidation process contributed more than adsorption process to the removal of COD.
