Abstract：Inordertotreattheclosedoldkilnwaterincoalmine，theexperimentalstudyonthetreatmentofacidmnedrainageby sulfatereducing bacteria wascariedout.Thein-situscreened sulfate-reducing bacteria wereaddedtotheacidminedrainage collected in situ，and two carbon sources of sodium lactateand corncob were added respectively for a 35- day experiment. The results showed that the addition of sodium lactate had a higher pH improvement effect and Mn2+ removal rate for acid mine drainage.TheremovalrateofSO4inwastewaterwas higherwithcorncobascarbonsource.Undertheconditionoftwokindsof carbon source can basically completely remove Fe2+ in wastewater.Correlation analysis was used to explore the correlation between thecomponentsoftheexperiment.Theresultsshowedthatthereasasignficantpositivecoelationbetweenthecomponentswhen sodiumlactatewasusedasthecarbon source.Whencorncob wasusedascarbonsource，there wasasignificantpositivecorelatin between the other components except that there was no significant correlation between pH value and Fe2+ removal rate.
