Abstract：With the acceleration of industrialization, the discharge of wastewater containing heavy metal ions continues to threaten the environment and human health. When traditional chemical precipitation, adsorption and other methods are used to treat complex industrial wastewater, problems such as secondary pollution, insufficient treatment efficiency or high cost often occur. With controllable operation, mild reaction conditions and no need for additional chemicals, electrochemical method has gradually become a research hotspot in the field of water treatment. The purpose of this paper is to systematically analyze the core mechanisms of electrochemical redox, electrocoagulation and electroflotation, and explore the influence of different electrode materials, current density, pH value, reaction time and other operating parameters on the removal efficiency.
