Abstract: The disclosure discloses a method for enhancing denitrification of sewage with a low carbon-to-nitrogen ratio by using an electrode biocarrier, and relates to the field of sewage treatment. The disclosure uses a conductive material as a microbial carrier and a potentiostat to induce a micro-electric field for directional acclimation and enrichment of electroactive denitrification microorganisms, and realizes a high-efficiency denitrification of the sewage with a low carbon-to-nitrogen ratio. The disclosure aims to provide a technical method for solving the problem of deep denitrification of municipal sewage with a low carbon-to-nitrogen ratio.
