The inorganic nitrogen removal and microbial species in CW-BER and CW were compared. Removal efficiency of NH3-N and NO3-N have been significantly promoted in CW-BER. Nitrate removal in CW-BER decreased with current intensity increased to 15–20 mA. Relative abundance of Thiobacillus in CW-BER was apparently higher than that of CW.
