摘　　要：含硫酸盐有机废水多元污染物并存,严重影响水体生态环境,危害人体健康,是目前水污染控制领域面临的难题与关注的焦点。在目前所采用的生物法水处理中,硫酸盐还原菌(SRB)是降解该类废水的关键微生物。重点阐述了SRB处理含硫酸盐有机废水的原理和相关技术的研究进展,详细介绍了SRB的分类、相关检测技术及其在水处理领域的应用现状和存在的问题,并通过分析SRB在醇类、羧酸、烃类和大分子有机物降解方面的应用,指出将硫酸盐最终转化为单质硫并回收高纯度硫是SRB处理含硫酸盐有机废水今后的发展方向。Because of the production of sulphide, which is highly reactive, corrosive and toxic, organic wastewater containing sulphate is one of the focus in the control of water pollution. Sulphate reducing bac teria （SRB） are anaerobic microorganisms that use sulphate as a terminal electron acceptor by degrading organic compounds,which plays an important part in the treatment of sulphate-containing wastewatcr. SRB have been studied for more than 100 years, but it is only with the emergence of new genomic techniques and molecular biology that we have begun to obtain accurate information on their way of life. Thercforc,this paper intends to provide a research review of mechanism and methods for treatment of organic wastewater containing sulphate by SRB,particularly introduces the classification of SRB and its application in organic wastewater treatment and proposes the application prospects of SRB after the analysis of its application in alcohol, carboxylic acid, hydrocarbon and organic macromolecules wastewater treatment. Finally, the paper gives a discussion on the problems of the treatment of organic wastewater containing sulphate by SRB. To realize resource utilization , future research should break through the traditional concept of bio-dcsulfurization and contend to develop a high efficiency process for the simultaneous removal of organic compounds and sulfate, and control the elemental sulfur production as a final product.
