2、解決辦法
1、 對活性污泥泥齡控制上的要求
為了保證生化系統(tǒng)運行過程中活性污泥不會因為排泥不及時而發(fā)生老化，我們要經常確認當前排泥流量和活性污泥濃度之間的關系，通過食微比的確認，間接指導活性污泥排泥流量的控制。同時，必須做到排泥流量的均勻性，避免間隙的、流量波動過大的排泥方式。
2、曝氣的均勻性和過曝氣的防止
要求對曝氣量進行有效的控制，避免過曝氣，將曝氣池出口的DO濃度控制在2.5mg/L左右即可。同時也可降低曝氣過度消耗的電能，為降低處理成本打下基礎。
3、低負荷運行狀態(tài)的避免
要避免低負荷運行狀態(tài)的出現(xiàn)，從而規(guī)避活性污泥老化的發(fā)生。除了盡可能地提高進水中底物的濃度和可生化性， 更多的要盡可能地降低活性污泥的濃度，以保證食微比能夠保持在合理控制值內（0.15-0.25左右）。必要時可以補充外加碳源來保證活性污泥的正常運行繁殖功能，如投加化糞池水、引入生活污水等。
4、增加MBR工藝
MBR工藝替代了二沉池，使HRT與SRT分離，其過濾效果保證了長期嚴重的污泥老化，而不對出水產生太大的影響，既然出現(xiàn)了問題，那我們直接把出問題的人干掉，那不就沒問題了，MBR就是這么簡單而粗暴！

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...
