摘　　要：将短程硝化-反硝化生物脱氮技术与传统生物脱氮技术进行了比较,论述了短程硝化-反硝化生物脱氮技术的机理及特点。分析了实现亚硝酸盐积累的影响因素,包括温度、溶解氧浓度、pH值、分子态游离NH3浓度和泥龄。结合典型工艺,提出了目前短程硝化-反硝化脱氮技术存在的问题及改进建议。The comparison of shortcut nitrification-denitrification technology with the traditional technology was made. The mechanism and characteristics of the shortcut nitrification-denitrification technology were described. Several factors affecting NO2-N accumulation, including temperature, dissolved oxygen concentration, pH value, free ammonia concentration and sludge retention time, were analyzed. By comparison with the typical processes, the existing problems and several suggestions for this technology were presented.
