1. An electroactive bio-carrier module, comprising:
(1) a circular-distributed carbon brush electrode bio-carrier module,
wherein the circular-distributed carbon brush electrode bio-carrier module is formed by combining a plurality of carbon brushes; each carbon brush having a diameter of 1.5-3.0 cm and a length of 10-30 cm;
the carbon brushes are configured to be soaked in hydrochloric acid and then dried in air after impurities are removed from surfaces of the carbon brushes; a first titanium wire and plastic screws are used to connect the plurality of carbon brushes treated in series to the first titanium wire at an interval of 20-50 mm; one end, i.e. an upper end, of each carbon brush is fixed to the first titanium wire; the first titanium wire is enclosed end to end to form a ring, and a carbon brush is fixed at a center of the ring; the circular-distributed carbon brush electrode bio-carrier module in whole is of a cylindrical structure formed by the carbon brushes axially disposed in parallel;
(2) a corrugated stainless steel mesh electrode bio-carrier module,
the corrugated stainless steel mesh electrode bio-carrier module is formed by combining a plurality of corrugated stainless steel meshes stacked in parallel; lengthwise directions of corrugations of adjacent upper and lower corrugated stainless steel meshes are perpendicular to each other; one layer and another layer of the adjacent upper and lower corrugated stainless steel meshes are fixedly connected via a second titanium wire.
