摘　　要：在煤炭开采过程中,产生的煤矿酸性废水(ACMD)具有pH低,重金属离子、硫酸根离子浓度较大等特点,同时,会导致严重的环境污染问题。目前处理ACMD的方法有化学法、物理法和生物法,而以硫酸盐还原菌(SRB)为主的生物法是一种极具应用前景的技术。本文系统地阐述了ACMD产生的主要原因,介绍了SRB处理ACMD的机理和影响SRB还原作用的主要因素,讨论了目前存在的问题,认为硫酸盐还原菌治理煤矿酸性废水应主要从源头治理、多种方法组合进行、加强对微生物驯化三个主要方向进行。In the process of coal mining,produced acidic coal mine drainage(ACMD)have the characteristics of low pH,high concentration of heavy metal ions and sulfate ions,meanwhile,leading the problem of seriousenvironmentpollution.At present,chemical,physical and biological methods are used to treat ACMD.Biological methods based on sulfate reducing bacteria(SRB)are promising technologies.This paper systematically expounds the main causes of ACMD,introduces the mechanism of SRB treating ACMD and the main factors affecting the reduction of SRB,finally discusses the existing problems,it is considered that SRB should be used to treat acidic wastewater from coal mines mainly in three main directions:source treatment,combination of various methods and strengthening domestication of microorganisms.
