Problems solved by technology

[0022] However, this type of electrochemical technology has not been widely used on a large scale at present. The main reason restricting its wide application is its high energy consumption. The soluble anode is easily polarized and passivated, which increases the power consumption of the treatment and reduces the treatment effect. , in practical applications, the plates need to be replaced regularly and frequently, and due to its structural design, it is troublesome to replace the plates, and the workload is heavy

Description

Technical field [0001] The present invention mainly relates to the field of wastewater treatment equipment, and particularly refers to an electrochemical device for treating heavy metal wastewater. Background technique [0002] Scholars at home and abroad have done a lot of research on the treatment of heavy metal pollution. However, as the discharge standards become stricter, there are currently developed and applied methods for the treatment of heavy metal pollution wastewater, such as chemical precipitation, biological methods, and ion exchange. Certain limitations. The chemical precipitation method has the disadvantages of high operating cost, large area, unstable treatment effect, and difficult to meet the standard; biological method has disadvantages such as high requirements for water quality, low automation, and long project construction period. Physical methods such as ion exchange only It can treat a certain type and concentration of heavy metal ions. The electrochemi...
