温度是硝化细菌生长的限制因素，在5℃左右时硝化反应基本停止．研究低温条件下的好氧硝化效果，对低温条件下生物脱氮的正常运行具有重要意义．目前，国内外的研究多集中在现有工艺的改进和功能性细菌的筛选．其中，工艺的改进是通过优化运行操作条件等方式使其利于低温下硝化细菌的生长，包括对传统活性污泥法、SBR、A2／O等活性污泥法和生物膜法改进方面的研究．功能茵的筛选主要是通过长期驯化培养、优化菌群等方式实现的．

Temperature is one of the limiting factors for the growth of nitrifying bacteria, and nitrification nearly stops at 5 ℃ or so. It is very important for biological nitrogen removal to operate normally at a low temperature to study the aerobic-nitrification at low temperature. At present, more research at home and abroad is about improvement of processes available now and selection of functional bacteria. Among them, research on process improvement, which includes conventional activated sludge, SBR, A2/O and so on, can favor the growth of nitrifying bacteria at low temperature by the optimizing operating conditions. Selection of functional bacteria can be achieved by those measures, such as long-term acclimation and colony optimization.
