Abstract: An electroactive bio-carrier module and a sewage treatment device using same are provided, which relate to the field of bioelectrochemistry and sewage treatment. The electroactive bio-carrier module is composed of an anode module and a cathode module made of a conductive material. The anode module is formed by connecting carbon fiber brushes in series and is of a vertically ring type structure; the cathode module is formed by connecting stainless steel meshes in series; the stainless steel meshes are in a folded horizontal stacked design; the anode and cathode modules are connected through an external lead wire to form a circuit. Surfaces of the anode and cathode modules can both enrich microorganisms, biofilms are formed on the surfaces. The electrode module is arranged in an up-flow type sewage treatment device and is used as an electroactive bio-carrier, to form a hybrid sewage treatment device with a built-in electroactive bio-carrier.
