【Abstract】 Electrochemical oxidation technology is a typical environmentally friendly technology with excellent oxidation efficiency on the difficult biodegradable substances. At present, the electrochemical oxidation studies are mainly focused on the modification of the electrocatalytic anode, the improvement of the electrochemical oxidation system and the optimization of the parameters of the electrochemical oxidation process. However, the current supply mode of the electrochemical oxidation process is rarely concerned. It is mainly reviewed four modes of current supply in electrochemical oxidation technology,including constant voltage power supply mode,constant current power supply mode,pulse power supply mode,and dynamic current regulated power supply mode. It is pointed out that the pulse mode can effectively alleviate the mass transfer problem in the electrochemical oxidation process compared with the formers,thereby greatly improving the degradation efficiency. The method lays a better foundation for the engineering application of electrochemical oxidation technology.更多还原
