| Abstract: | Shortcut nitrification - denitrification is a process of biological denitrification via nitrite during which nitrification is controlled to the nitrite - type nitrification and subsequently denitrification happens under the anoxic condition.The principal of traditional biological nitrogen removal and shortcut nitrification-denitrification is compared in this paper.The most important thing is how to control the factors affecting the accumulation of NO-_2-N during the nitrification process. These factors including temperature , free ammonia,pH, dissolved oxygen , dangerous materials and sludge age are analyzed and controlled conditions in realizing shortcut denitrification are suggested. |

| Keywords: | biological nitrogen removal shortcut nitrification - deitrification NO-_2- N |
