| 摘 要： | 短程硝化反硝化是指将硝化过程控制在亚硝化阶段，随后在缺氧条件下进行反硝化的生物脱氮过程。以亚硝酸盐为电子受体的短程硝化反硝化，其关键是如何实现亚硝酸盐的积累。本文主要介绍了以亚硝酸盐为电子受体的短程硝化反硝化的机理，以及影响亚硝酸盐积累的多种因素，包括C/N、 FA （游离氨）、 DO、 pH等，探讨了短程硝化反硝化实现的主要工艺的途径。

| Abstract: | Shortcut nitrification-denitrification was a process of biological denitrification vianitrite during which nitrification was controlled to the nitrite-typenitrification and subsequently denitrification happened under the anoxic condition. With nitrite as electron acceptor shortcut nitrification and denitrification, the most important thing was how to realize the accumulation of nitrite. The mechanism of shortcut nitrification-denitrification to nitrite as electron acceptor, a variety of factors influenced the accumulation of nitrite, including the C/N, FA （ free ammonia） , DO, pH. The processes of partial nitrification-denitrification were discussed finally. |
