%X The decomposition of multi-metal mine tailings results in some environmental problems and disasters,studies show that acidophilic bacterias,represented by Thiobacillus ferrooxidans,play an important role in the process of decomposition of minerals.The inhibitation of Fe~(2+) oxidation was analyzed by adding different doses of bactericides into the solution of purified Thiobacillus ferroxidans.The effects of two bactericides.SDS and CTAB in inhibition of Thiobacillus ferroxidans in mineral tailings,were researched.The lab experiment showed that both bactericides (SDS and CTAB) are effective in inhibiting the activity of Thiobacillus ferroxidans.The inhibition rate of controlling Fe~(2+) oxidation is 82.83% with SDS at the concentration of 30 mg/L,and that of CTAB is 80.84% at the concentration of 5 mg/L.Bactericide technology can be used to control the acidification of sulfide tailings pollution and promote ecological reconstruction.
