摘要
Abstract
During wastewater treatment,denitrification is the core step of biological nitrogen removal systems.How-ever,excessive low temperatures can cause a decrease in the efficiency of denitrification process treatment and the effluent quality is difficult to meet discharge standards.Firstly,several common denitrification processes of conven-tional denitrification process,autotrophic denitrification process,and aerobic denitrification process were intro-duced including their biochemical and microbiological characteristics;Subsequently,the adaptive mechanisms of denitrification processes to low temperature conditions were systematically elucidated.The impacts of low tempera-ture on nitrogen removal performance,sludge properties,microbial community structure and activity,and the metabolic mechanisms of functional denitrifying bacteria were key reviewed;The stable operation strategies of deni-trification nitrogen removal process under stable and low temperature stress are summarized in recent years.And the corresponding engineering operation guidelines are proposed,which provide a reference for the efficient operation of denitrification processes of low temperature wastewater treatment plants in winter.关键词
