BAF工艺在污水处理厂提标改造中的应用

The Application of BAF Process in the Upgrading and Reconstruction of Sewage Treatment Plant

曝气生物滤池工艺具有处理效果好、占地小、投资少等优点,已成为国内外研究和应用的热点。结合某大型城市污水处理厂中曝气生物滤池的前期运行分析,对污水处理厂提标升级改造的总体方案进行比选,确定了采用三段式BAF工艺的推荐方案,同时对BAF工艺优化设计中的关键参数进行了探讨。

The biological aeration filter process has many advantages,such as good treatment effect,small footprint,less investment,etc.,which has become a hot topic of research and application at home and abroad.Combined with the analysis of the early operation of BAF in a large-scale sewage treatment plant,the overall scheme of upgrading and reconstruction of the sewage treatment plant is compared,and the three-stage BAF process is recommended.At the same time,the key parameters of BAF process optimization are discussed.
