摘　　要：根据目前油田杀灭硫酸盐还原菌的状况,提出反硝化抑制硫酸盐还原菌活性的设想.综述了反硝化抑制硫酸盐还原菌活性的机理,及其在国外油田污水处理中工程应用的效果、影响因素和存在的不足.提出在机理研究中,加强蛋白组学和环境基因组学方面的研究,特别是投加抑制物质如硝酸盐、反硝化细菌等对硫酸盐还原菌本身的基因和蛋白表达的影响,代谢途径的抑制研究,加强微生物分子生态学方法在理论研究和工程实践中的应用.同时对该机理在我国大庆油田的应用提出一些研究思路.This paper discusses the mechanism and application of denitrification inhibition to the activity of sulfate - reducing bacteria in wastewater treatment of domestic and overseas oilfields. All factors affecting this process and shortcomings in the process were reviewed as well. It is suggested that the study on protein structure and environmental gene is important for the mechanism research, particularly for studying the effect of addition of inhibiting agents, such as nitrate and denitrifying bacteria, on the gene and protein structure of sulfate - reducing bacteria as well as the metabolism process. It is critical to investigate this process from the view of microbial molecular ecology. The case application has also been studied for Daqing Oilfield.
