流态化电极处理含金属废水过程的研究--金属在阴极颗粒电极上沉积的传递特性

基于膜扩散理论，提出了流态化条件下金属离子自溶液主体向阴极颗粒电极表面传递、沉积、成长的速率方程；讨论了由于表面反应热和流体流动造成温度分布不均匀而引起的传热及其对金属的流态化颗粒电极上沉积成长过程的影响。为流态化电极处理含金属废水过程的传质、传热强化提供了依据。

STUDY ON THE TREATMENT OF METAL-CONTAINING WASTEWATER BY FLUIDIZED BED ELECTRODE--Transport Phenomena of Metal Deposition on Cathode Particle Electrode

Based on the film diffusion theory, rate equations are developed to describe the transfer, integration and growth processes of metal ions from the bulk solution to the cathode particle electrode surface under fluidization conditions. The heat transfer of this process is discussed to expound the important role played in deposition processes by the influence of the reaction heat released at the electrode surface and the non_uniform temperature distribution caused by hydrodynamics. It provides a basis for enhancing the mass transfer and heat transfer in the treatment of metal_containing wastewater by fluidized bed electrode.
