摘　　要：短程硝化反硝化技术是将硝化反应控制在亚硝酸盐阶段,不进行亚硝酸盐至硝酸盐的转化,直接进行反硝化反应。文章阐述了短程硝化反硝化的形成机理,理论研究进展,系统介绍了短程硝化反硝化影响因素与控制分析。Shortcut nitrification-denitrification technology means to control nitrification within the stage of nitrite nitrification,without the conversin of nitrite into nitrate,which wais denitrification directly.The paper expatiated on the formation of shortcut nitrifiation-Denitri-fication mechanism and the progress of theoretical research.It also described the influencing factors and control analysis of shorcut nitrification-denitrification.Finally,it discussed some points of shortcut nitrification-denitrification technology,which needs in-depth study.

关 键 词：短程硝化反硝化 亚硝酸积累 生物脱氮
