加熱措施
(1) 曝氣池、二沉池等池壁采用發(fā)泡保溫板保溫，外砌磚圍護(hù)（爐渣、膨脹珍珠巖等填充）結(jié)構(gòu)，池頂加蓋等保溫措施；
(2) 鼓風(fēng)機(jī)一側(cè)設(shè)空氣預(yù)熱室，將冬季-10～-20℃的冷空氣預(yù)熱到5～8℃；空氣管道設(shè)置管廊，便于保溫處理等。
(3) 適當(dāng)加熱污泥，包括回流污泥；
(4) 用熱蒸汽給進(jìn)入曝氣池的污水加熱。

生物固定化（填料）
此外，微生物經(jīng)包埋固定后持留能力得以增強(qiáng)，可望實(shí)現(xiàn)反應(yīng)器的快速啟動(dòng)和高效穩(wěn)定運(yùn)行。
固定化會(huì)使微生物活性有所降低固定化后，傳質(zhì)阻力會(huì)增大，氧的傳質(zhì)阻礙尤為明顯，固定化更能在厭氧條件下發(fā)揮其優(yōu)勢(shì)。此外，其成本也有待技術(shù)經(jīng)濟(jì)評(píng)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...
