摘      要：In order to explore the effect of particle position on the electrocatalytic reaction rate at different positions in three-dimensional electrocatalytic reactor,using methylene blue as the simulated organic wastewater,and spherical graphite particles as the particle electrode,the potential distribution in three-dimensional electrocatalytic reactor was simulated by using COMSOL Multiphysics software.A multivariate logarithmic regression model of reaction kinetic constant and position was established by mathematical *** electrocatalytic reaction rates were predicted at different locations in the *** results show that the degradation ability of particle electrode to pollutants is uneven in the electrocatalytic *** increase of electric field intensity and particle size will improve the difference of reaction *** closer the particle electrode is to the anode,the stronger the pollutant degradation ability would *** reaction rate of the same particle electrode at different locations varies greatly,which can be roughly divided into three regions according to the degree of difference,among which the central region of the particle has the highest electrocatalytic reaction efficiency.
