Six reactors, including iron-carbon micro-electrolysis coupling with sulfate reducing bacteria (Fe/C-SRB), aluminum-carbon micro-electrolysis coupling with sulfate reducing bacteria (Al/C-SRB), carbon coupling with sulfate reducing bacteria (C-SRB), iron-carbon micro-electrolysis (Fe/C), aluminum-carbon micro-electrolysis (Al/C) and carbon (C), were designed to investigate their effects on the remediation of U, Mn, Zn, SO24- and NO-3 in the percolate water from the uranium tailings reservoir. The results indicated that the concentration of U in...
