摘　　要：低温会影响脱氮菌细胞活性,导致北方地区污水处理厂冬季极易出现出水氮超标问题。介绍了目前筛选到的低温脱氮菌的种类及耐冷机制,分析了污水处理厂冬季出水氮超标的主要原因,总结了低温脱氮菌的工程应用现状,并展望了低温脱氮菌未来主要的研究方向。Low temperature can affect the cellular activity of denitrifying bacteria,which leads to the problem of effluent nitrogen exceedance of sewage treatment plants in northern China in winter.In this paper,we introduce the types and cold resistance mechanism of low temperature denitrifying bacteria,and analyze the main causes of effluent nitrogen exceedance of sewage treatment plants in winter.Moreover,we summarize the application status of low temperature denitrifying bacteria in engineering,and put forward the prospect in the main research directions of low temperature denitrifying bacteria in the future.

关 键 词：低温脱氮菌 耐冷机制 氮超标
