摘要: Abstract A membrane-less anoxic bioelectrochemical treatment (AxBET) system was evaluated to study the influence of bioelectrogenic activity during chemical wastewater (CW). Increment in power generation observed with increase substrate loading (61-204 mW/m2) indicating ability anodic bacteria BET utilize complex chemicals as sole carbon source. Derivative analysis voltammograms depicted by positive and negative peak potentials which relate extracellular electron transport sites (EETs) that presumably play a significant role transfer. These self-driven redox mediators varied respect load. The microbial population dominated anaerobic microorganisms are commonly involved effluent plants initial phase operation. gradual shift community towards enrichment electrogenically active belonging phyla viz., Firmicutes Proteobacteria after prolonged Shannon Index principal component correlated profile studies. feasibility bioremediation an AxBET demonstrated bioelectricity production along multipollutant removal simultaneously.
