AB  - Adding Fe(III) into a MEC - anaerobic reactor enhanced the degradation of organic 
      matters. To clarify the respective effects of combining Fe(III) dosage and a MEC 
      and Fe(III) dosage only on strengthening anaerobic digestion, three anaerobic 
      reactors were operated in parallel: a MEC - anaerobic reactor with dosing Fe(OH)3 
      (R1), an anaerobic reactor with dosing Fe(OH)3 (R2) and a common anaerobic 
      reactor (R3). With increasing influent COD from 1500 to 4000 mg/L, the COD 
      removal in R1 was maintained at 88.3% under a voltage of 0.8 V, which was higher 
      than that in reactor R2 and R3. When the power was cut off, the COD removal in R1 
      decreased by 5.9%. The addition of Fe(OH)3 enhanced both anaerobic digestion and 
      anodic oxidation, resulting in the effective mineralization of volatile fatty 
      acids (VFAs). The reduced Fe(II) combined with electric field resulted more 
      extracellular polymeric substances (EPS) production. Quantitative real - time PCR 
      showed a higher abundance of bacteria in the anodic biofilm and R1. 
      Pyrosequencing and denaturing gradient gel electrophoresis (DGGE) analysis 
      revealed that the dominant bacteria and archaea communities were richer and more 
      abundant in the anode biofilm and R1.
