摘　　要：以人工配水为进水，接种某污水厂氧化沟工艺冬季的活性污泥，在（32±1）℃下快速启动一套容积为3．2L的UASB／生物膜厌氧氨氧化反应器后，将加热水浴锅关闭，考察该反应器在常温（20～24℃）下的生物脱氮效果。结果显示，在常温下厌氧氨氧化反应仍然是该反应器内的主导反应，厌氧氨氧化茵活性很高，对NH4-N、NO2- —N、TN的平均去除率分别为99．7％、98．0％和97．7％。Fed with artificial wastewater and seeded with activated sludge from an oxidation ditch at a municipal wastewater treatment plant, a 3.2 L UASB/biofilm anaerobic ammonia oxidation （ ANAM- MOX） reactor was started-up at （32±1）℃. After the reactor reached stable operation, the heating wa- ter bath was turned off, and the biological nitrogen removal of the UASB/biofilm ANAMMOX reactor was investigated at room temperature （20 to 24 ~C ）. The results showed that at room temperature, anaerobic ammonia oxidation was still dominant in the reactor, the activity of ANAMMOX bacteria was high, and the removal rates of NH4＋ - N, NO2- - N and TN were 99.7% , 98.0% and 97.7% , respectively.
