Description

technical field

[0001] The invention relates to the field of sewage treatment and the field of porous conductive materials, in particular to an activated carbon electrode and its preparation method and application. Background technique

[0002] Water pollution prevention and control is one of the most urgent environmental problems in the world. In actual waters, sewage includes inorganic sewage mainly containing inorganic pollutants, organic sewage mainly containing organic pollutants, mixed sewage containing both organic and inorganic substances, and heavy metal sewage. The water quality of all kinds of sewage varies greatly, the composition is complex, and the treatment is difficult.

[0003] Activated carbon is activated by natural carbonaceous materials under high temperature and anoxic conditions. It has a lot of micropores and a huge specific surface area, and has a strong physical adsorption capacity. In addition, during the activation process of activated carbon, it...
