description A method for enhancing low-temperature denitrification performance of anaerobic ammonium oxidation bacteria comprises the following steps: acquiring anaerobic ammonium oxidation original inoculant cultured at an initial culture temperature above 20 DEG C; the cultivation temperature is reduced to 15 DEG C, and cultivation is conducted for 1-5 days; the cultivation temperature is reduced to 3-6 DEG C, and cultivation is conducted for 1-5 days; raising the cultivation temperature to 10-15 DEG C, and cultivating for 1-3 days; and repeating the steps at least once. In a sewage treatment system, by adopting the method disclosed by the invention, the activity and denitrification stability of inoculated anaerobic ammonia oxidation sludge can be remarkably improved, and the engineering applicability and low-temperature adaptability of anaerobic ammonia oxidation are greatly improved. 一种强化厌氧氨氧化菌低温脱氮性能的方法，包括获取在初始的培育温度下培育的厌氧氨氧化原始接种菌，所述初始的培育温度在20℃以上；将培育温度降至15℃，并培育1～5天；将培育温度降至3～6℃，并培育1～5天；将培育温度提高至10～15℃，并培育1～3天；重复上述步骤至少一次
