文摘

A cathode-anode flow-through bioelectrochemical reactor is used for effective CAHs bioremediation. The mixed metal oxide (MMO) electrode is used to stimulate anodic oxidative dechlorination. Graphite present in the anode hinders oxygen production decreasing oxidation yield. Oxygen back-diffusion not affects the cathodic reductive dechlorination. Ecotoxicity tests show progressive toxicity reduction from inlet to anodic effluent.
