| 摘 要： | 利用从黄土中分离的硫酸盐还原菌修复煤矸石酸性污染,以乳酸钠作碳源,探讨了加不同量碳源和不同接种量情况下硫酸根的去除率,并对煤矸石浸液的pH值、氧化还原电位和电导率的变化作定量测定,研究了硫酸盐还原菌的几种影响条件.实验结果表明:利用硫酸盐还原菌来修复煤矸石酸性污染的思路可行,向煤矸石中接种硫酸盐还原菌硫酸根最高转化率可达95.5%，可提高煤矸石浸液的pH值，降低其氧化还原电位和电导率，从源头上抑制酸矿水的产生，能有效控制含硫煤矸石在降雨酸性淋溶的环境污染.

| Abstract: | Sulfate-reducing bacteria(SRB) was isolated from the loess polluted by acid mine drainage(AMD) from coal wastes.The aim of this test is to study the possibility of using SRB for remediating sulfuric pollution from coal wastes,which is considered to be the major environmental problem associated with coal mining activities.Tests were conducted to determine if the bacteria produced hydrogen sulfide could be used for the removal of sulfate and the increase of pH of AMD from coal wastes.Investigated the mechanis... |
