曝气生物滤池与三段生物滤池脱氮除磷对比

Comparison of Nitrogen and Phosphorus Removal between Biological Aerated Filter and Three-stage Biofilter

生物法脱氮除磷具有无害高效的特点,是目前工艺设计都会优先考虑的一种方法。生物脱氮除磷的工艺一直都在变化,曝气生物滤池就是对传统生物滤池的一种改进,本文对曝气生物滤池与传统的三段生物滤池进行对比,立足于传统的三段生物滤池,结合曝气生物滤池的工艺特点,分析曝气生物滤池的优势与不足,并探究其不足,讨论可以解决的方法。

Biological nitrogen and phosphorus removal has the characteristics of harmless and high efficiency, and it is a method that is prioritized in current process design. The process of biological nitrogen and phosphorus removal has been changing. The biological aerated filter is an improvement of the traditional biological filter. In this paper, the biological biological filter is compared with the traditional three-stage biological filter, based on the traditional The three-stage biofilter, combined with the process characteristics of the aerated biological filter, analyzes the advantages and disadvantages of the aerated biofilter, and explores its shortcomings, and discusses the methods that can be solved.
