Summary: This study enhanced the mass transfer of hydrophobic contaminants in a microbial fuel cell-based trickling filter (MFC/TF) by adding non-aqueous phase liquid. The addition of 10% silicone oil increased the removal efficiency, mineralization efficiency, and elimination capacity of styrene by 1.56 times, 1.86 times, and 1.52 times respectively. It also increased the power density by 2.6 times and reduced the internal resistance by approximately 22%. The improvement in performance was mainly attributed to the decrease in internal resistance and the increase in the number of electricity-producing bacteria after adding silicone oil.
