Electrochemical technology is very promising for biorefractory organic wastewater treatment. The key of the technological application is to develop high efficiency, stability, and low cost electrode materials. Lead dioxide electrode, which is extensively used in industrial fields, has relatively high oxygen overpotential and electro-catalytic activity. So PbO2 is considered as a promising electrode used in the electrochemical degradation of biorefractory organic wastewater. In this paper, an overview is made on the preparation and improvement of lead dioxide electrode and its application to the electrochemical oxidation treatment of biorefractory organic wastewater. As results, the trend of future studies is analyzed and suggestions are given.
