流化床填料

好氧生物流化床工艺中采用立体空心填料为好氧生物载体，填料为中空结构，正常运行填料悬浮在水中。 填料内部生长厌氧菌，产生反硝化作用可以脱氮；外部生长好氧菌，去除有机物，整个处理过程中同时存在硝化与反硝化过程。 
In aerobic biological fluidized bed systems, three-dimensional hollow fillers serve as biological carriers. These hollow-structured fillers maintain suspension in water during standard operation. Anaerobic bacteria grow inside the filler, producing denitrification to remove nitrogen, while aerobic bacteria grow on the outside to remove organic matter. Both nitrification and denitrification processes occur simultaneously throughout the entire treatment process.
