3、污泥解體(tǐ)
4、污泥老化
2、解决办法
1、 对活性污泥泥龄控制上的要求
為(wèi)了保证生化系统运行过程中活性污泥不会因為(wèi)排泥不及时而发生老化，我们要经常确认当前排泥流量和活性污泥浓度之间的关系，通过食微比的确认，间接指导活性污泥排泥流量的控制。同时，必须做到排泥流量的均匀性，避免间隙的、流量波动过大的排泥方式。
2、曝气的均匀性和过曝气的防止
要求对曝气量进行有(yǒu)效的控制，避免过曝气，将曝气池出口的DO浓度控制在2.5mg/L左右即可(kě)。同时也可(kě)降低曝气过度消耗的電(diàn)能(néng)，為(wèi)降低处理(lǐ)成本打下基础。
3、低负荷运行状态的避免
要避免低负荷运行状态的出现，从而规避活性污泥老化的发生。除了尽可(kě)能(néng)地提高进水中底物(wù)的浓度和可(kě)生化性， 更多(duō)的要尽可(kě)能(néng)地降低活性污泥的浓度，以保证食微比能(néng)够保持在合理(lǐ)控制值内（0.15-0.25左右）。必要时可(kě)以补充外加碳源来保证活性污泥的正常运行繁殖功能(néng)，如投加化粪池水、引入生活污水等。
4、增加MBR工艺
MBR工艺替代了二沉池，使HRT与SRT分(fēn)离，其过滤效果保证了長(cháng)期严重的污泥老化，而不对出水产生太大的影响，既然出现了问题，那我们直接把出问题的人干掉，那不就没问题了，MBR就是这么简单而粗暴！

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...
