During the process of industrial and agricultural production, mineral mining and urbanization, a large amount of wastewater containing a variety of naturally non-degradable heavy metal ions will be produced. If such persistent toxic environmental pollutants are discharged directly without any treatment, they will pose a serious threat to biodiversity, including humans.Heavy metal wastewater can be treated by a variety of purification and separation technologies. As an emerging treatment method, electrochemical technology has significant advantages and development potential in the treatment of heavy metal wastewater.Based on the importance and urgency of purifying heavy metal ions in wastewater, this paper introduces the latest progress of electrochemical treatment methods based on different action mechanisms, and deeply analyzes the research status of different electrode materials used in different electrochemical treatment methods to treat heavy metal ions, in order to provide theoretical reference for the further development of heavy metal ion wastewater treatment.
