ØThe bioanode did not significantly increase the DOC consumption, removal efficiencies of BaP and microbial community structures in S1 cm in comparison with S11 cm.
ØInstead, the bioanode accelerated the DOM humification process and the transformation from HMW UVC humic acid-like to LMW UVA humic acid-like and fulvic acid-like components, significantly reduced the consumptions of inorganics that as electron acceptors, and increased the biodegradation extent of BaP in S1 cm.
On the bioanode, EAB and some PAH degraders were both enriched and the energy metabolism could be upregulated to generate more ATP. |
