Abstract The methyl orange simulated wastewater has been treated by a three-dimensional-electrode processin which load-type activated carbon was used as particle electrodes. Effects of different particle electrode and the factors affecting the removal efficiency of COD and degradation of color were studied. Kinetics and the degradation mechanism of methyl orange simulated wastewater was studied by UV-visible absorption spectra. Loading manganese compounds’ particle electrodes could get best effect, the corresponding color and COD degradation rate reached about 97% and 80% after 3h, respectively. Experimental results showed that the optimal operating conditions were as follows: cell voltage 12V, initial pH value 3, concentration of supporting electrolyte 0.05mol/L. The analysis results from kinetics indicated that the degradation of methyl orange was first-order kinetics. Analytical results from UV-visible absorption spectra indicated the color and COD were well degraded by three-dimensional-electrode process using load-type activated carbon as particle electrodes.
