极板材料对三维电极反应器中电极电位分布形式的影响

Electrode Potential Distributive Styles in Three-Dimensional Electrode Reactor as Affected by Electrode Material

对废水处理所使用的以颗粒状活性炭为填料的三维电极反应器中电极电位的分布进行了测定,并根据测定结果,将不同极板材料(包括铜、不锈钢、钛、铅、铁、铝、镍、石墨、表层镀有Ir和Ru的钛网)反应器中电极电位的分布状况归为中心对称无极值型、中心对称极值型和非对称无交点型.同时,测定了不同反应器中不同电压下的电流值,发现在个别反应器中电流与电压之间偏离了线性关系.

Electric potential (EP) distribution in a three-dimensional electrode reactor, which contains a cylindrical packing of soaked granulated carbon sandwitched with two flat electrodes, was measured to obtain basic knowledge of electrochemical reactor for waste water treatment. The materials used for the electrodes are copper, stainless steel, Ti, Pb, Fe, Al, Ni, graphite, and titanium with Ir and Ru plated on its surface (TIR). The EP distributions along the reactor path can be divided into three styles: centro-symmetry without extrema style, centro-symmetry with extrema style and asymmetry without junction style. And the electrical currents in different reactors were measured too; some of them deviated the linearity and presented the extrema.
