摘　　要：电化学方法处理难降解有机废水是一种很有前途的技术,其应用的关键是开发出高效、稳定、低成本的电极材料。PbO2电极在工业领域具有广泛的应用基础,具有较高的析氧电势和电催化活性,被认为在电化学处理难降解有机废水方面有重要的应用前景。本文对PbO2电极制备方法与改性以及在难降解有机废水电化学处理中应用的研究成果和最新进展进行了综述,并对该研究领域今后的发展趋势进行了分析。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.
