▎ 摘  要

NOVELTY - Bioelectrolysis advanced treatment process for heavy metal polluted wastewater comprises (i) culturing Shewanellausing culture medium under aerobic conditions; (ii) fixing the bacteria after expansion to the first graphene carbon felt combination frame under anaerobic conditions; (iii) passing heavy metal polluted waste water to carry out domestication and cultivation of the first graphene carbon felt combination frame after the film-hanging culture to obtain the bacteria-containing graphene carbon felt combination frame; (iv) placing the bacterium-containing graphene carbon felt combination frame as the anode on the water outlet of the anaerobic tank, and then conducting the heavy metal polluted wastewater treatment with bioelectrolysis after the cathode is placed on the water inlet of the anaerobic tank. The culture medium comprises yeast powder, peptone and sodium chloride. USE - The method is useful for bioelectrolysis advanced treatment process for heavy metal polluted wastewater. ADVANTAGE - The processing technique efficiency is high, the bacteria film using period is long, does not generate a lot of solid waste, has environmental benefit, and bacteria film after separating heavy metal can be recycled.
