China Environmental Science, 2007,27(2)：150~154 Abstract ：The effect and stability of short-cut nitrogen removal of actual municipal wastewater were studied, adopting SBR technique large type scale system with treatment capacity of 60m3/d. Through comparing analysis of traditional time control model and on-line actual time control model, the reaction time reduced greatly and the external carbon source could be saved more than 25% with real-time control, under the premise of reaching nitrogen removal effect of same depth. The system based on the pledged average total nitrogen removal rate of 98.2%, obtained good short-cut nitration effect, the subnitration of each aerobic reaction was all above 95%
