Applications of electro-catalysis municipal wastewater treatment

Abstract

In the context of developing a more livable environment, people are paying more attention to the pollution problem. As the consumption of water resources increases, water pollution is one of the most serious problems people need to pay attention to the most. However, traditional methods cannot meet the requirements of treating wastewater while recovering resources. In this review, the application of electrocatalytic technology in municipal wastewater treatment is discussed. Specifically, the comparison between electrocatalysis and traditional methods is shown in this review. Various literatures on different types of materials of electrodes are included. Besides, two different types of electrodes and mechanisms of electrocatalysis and their application in multiple types of wastewater are also summarized. This review aims to arouse peoples attention to the wastewater problem and explore the further application of electrocatalytic technology in the future in order to rationally design new electrocatalytic systems for the recovery of energy and resources.
