A^2/O工艺污水处理厂提标改造技术探讨

Technical Discussion on Standard Raising and Reform in Sewage Treatment Plant by A^2/O Technology

介绍了一个A2/O工艺污水处理厂提标改造的设计、施工及运行调试过程,分析了该工程改变厌氧、缺氧和好氧三个阶段停留时间的比例,确保有效脱氮除磷;描述了污泥的储存回取和污泥菌种的培养;该工程的创新点是通过管道和阀门实现了A2/O工艺和倒置A2/O工艺之间的相互切换,为处理各种水质的污水增加了可能;总结了该类工程的设计和施工的经验,为类似工程提供了借鉴。

The paper presents the course of design, construction, operation and debugging of standard raising and reform in sewage treatment plant by A2/O technology, analyzes the proportion of settling-time of anaerobic, anoxic and oxidic three phases altered by the project so as to ensure the denitration and dephosphorization; the paper describes the storage and recovery of sewage and cultivation of sewage bacterium; the innovation point of the project is to realize the each other switch between A2/O technology and converting A2/O technology through pipes and valves. The paper sums up the experiences of design and construction of the project and provides use for reference in the similar projects.
