摘　　要：采用活性炭纤维作为电极材料,动态电吸附去除水中的2,4,6-三氯酚。考察了电压、极板间距、进水流量和沿程长度对三氯酚去除效果的影响,得出工艺最佳条件:电压1.0 V,极板间距4 mm,进水流量112.5 mL/min,沿程长度320 mm,三氯酚去除率达到98.31%。准一级动力学模型和Langmuir吸附等温线模型可较好地描述活性炭纤维对三氯酚的吸附行为。Activated carbon fiber as the electrode material has been used for removing 2,4,6-trichlorophenol（TCP）from water by dynamic electrosorption method,and the influences of voltage,plate spacing,influent flow rate and path length on TCP removing effect have been investigated.It is known that the optimum conditions are as follows：the voltage is 1.0 V,plate spacing 4 mm,influent flow rate 112.5 mL/min,and path length 320 mm.Under these conditions,the removing rate of TCP is 98.31%.The pseudo-first order kinetic model and the Langmuir adsorption isotherm model can be used for describing the adsorption behavior of ACF for TCP.
