摘　　要：反应器采用颗粒状活性炭为填料,中间位置添加隔膜,对极板和反应区电极电位的分布进行测定。结果表明:填料的隔膜处理使反应区电极电位分布规律明显,阴、阳极区靠近隔膜处的电极电位绝对值明显高于靠近两极处,且阴、阳极区电极电位绝对值都随外加电压的增大而增大;固定阳极板,改变阴极板材料,阴极板电极电位高低与极板材料性质密切相关;阴、阳极板电极电位的差值决定了阴、阳极反应区电极电位的变化方向。Electrode potential distribution of anode, cathode and reaction area in a three-dimensional electrode reactor, which contains a cylindrical packing of soaked granulated carbon sandwiched with septum at middle, was measured to obtain basic knowledge of electrochemical reactor. The results showed that the electrode potential distributions of reaction area were obvious orderliness with septum treatment. The electrode potential near septum place was higher obviously than that near anode and cathode electrode. The electrode potential of three-dimension electrode will rise with rising of applied voltage. The characteristics of cathode material decided electrode potential of cathode when the anode material was fixed and the cathode material varied. The difference between anode electrode potential and cathode electrode potential decided the change trend of electrode potential of the reaction area.
