加热措施
(1) 曝气池、二沉池等池壁采用发泡保温板保温，外砌砖围护（炉渣、膨胀珍珠岩等填充）结构，池顶加盖等保温措施；
(2) 鼓风机一侧设空气预热室，将冬季-10～-20℃的冷空气预热到5～8℃；空气管道设置管廊，便于保温处理等。
(3) 适当加热污泥，包括回流污泥；
(4) 用热蒸汽给进入曝气池的污水加热。

生物固定化（填料）
此外，微生物经包埋固定后持留能力得以增强，可望实现反应器的快速启动和高效稳定运行。
固定化会使微生物活性有所降低固定化后，传质阻力会增大，氧的传质阻碍尤为明显，固定化更能在厌氧条件下发挥其优势。此外，其成本也有待技术经济评估。

In recent years, the hygienic condition of dental unit waterline (DUWL) has gradually received attention in China. At the same time, many local standards have been introduced. For example, Beijing issued "DB11/T 1703- 2019 Technical Specifications for Waterway Disinfection of Oral Comprehensive Treatment Units" on December 25th, 2019, while Zhejiang Province issued "DB33/T 2307-2021 Technical Specifications for Cleaning and Disinfection of Dental Waterway Systems" on January 29, 2021. In fact, various countries in the world have begun to pay attention to issues related to waterway pollution in dental treatment units much earlier, and have made relevant specifications. This article summarizes the standards of various countries in this regard as follows: Foreign standards related to the waterway of dental treatment units In 1996, the American De...
