通过介绍短程硝化反硝化的脱氮机理,分析了温度、DO、游离氨（FA）浓度、pH、泥龄等对短程硝化反硝化效能的影响。短程硝化阶段反应温度控制在较低温度（12℃-14℃）或在30℃以上,DO控制在0.5 mg/L,游离氨浓度控制在1.0-5.0 mg/L,pH值维持在8左右,泥龄控制在氨氧化菌的世代周期和亚硝酸盐氧化菌的世代周期之间（11天至15天）,易实现亚硝酸盐的积累。

Effect of temperature,DO,FA,pH and sludge age on shortcut nitrification-denitrification is analyzed after the mechanism of shortcut nitrification-denitrification is introduced.Nitrite accumulation can be easily realized when low temperature（12-14 ℃） or high temperature（above 30℃） is kept,DO is about 0.5 mg/L,free ammonia concentration is between 1.0 mg/L and 5.0 mg/L,pH value is near 8.0,and sludge age is between the generation cycle of AOB and the generation cycle of NOB（11 d-15 d）,respectively.
