activated sludge floes的用法和样例：
- In the text, the forming process and the microbial ecology of the activated sludge floe in SBR (sequencing batch reactor) were observed and studied.
- The influence mechanism of the hydrodynamic shear stress was analyzed by comparison of the morphological characteristics of activated sludge floe and the types of microorganism.
- Over 300 strains of bacteria have been found in activated sludge.
- Acetate was degraded by denitrifying activated sludge.
- The trickling filter and activated sludge efficiencies cited required primary sedimentation and effluent circulation.
