摘　　要：针对煤矿酸性废水污染和SRB缺乏有机碳源的问题,本试验运用生活污水、锯末、鸡粪质量比为80∶7∶3的混合发酵液作为SRB碳源,研究SRB对SO42-、Fe2+、Cu2+的去除效果,并分析SRB对多种离子共存的AMD处理效果。结果表明,SRB采用新碳源是有效的,SRB对以上几种离子进行单一处理时均有良好的效果。SRB处理AMD时,其对SO42-、Fe2+、Cu2+的去除率可分别达到84.2%、92.8%、67.5%。Aiming at the problems of coal mine acid wastewater pollution and SRB lack of organic carbon sources,this experiment uses a mixed fermentation broth with a mass ratio of domestic sewage,sawdust and chicken manure of 80:7:3 as the carbon source of SRB to study the removal effect of SRB on SO42-,Fe2+,and Cu2+,and analyze the treatment effect of SRB on AMD with multiple ions coexisting.The results show that the new carbon source used by SRB is effective,and SRB has a good effect on the single treatment of the above ions.When SRB treats AMD,its removal rate of SO42-,Fe2+,Cu2+can reach 84.2%,92.8%,67.5%,respectively.
