Abstract:

According to the experiments of bio-affinity filler with high efficiency applied to the bio-fluidized bed, the filler bythe size of10 mm×10 mm×10 mmhas been chosen as the supporter ofbio-tluidized bed.The result shows that the effect offluidizingis good, and it is veryeasyfor the micro-organisms tohangon the films, sothe activated sludge donotlosewiththeeffluentwater.Thetreatmeanteffectcanbegreatlyimprovedafteraddingthefiller.
