MECHANISMS OF BIOFILM DETACHMENT IN ANAEROBIC FLUIDIZED BED REACTORS

摘要

Biofilm growth and detachment mechanisms in anaerobic fluidized bed reactors 9AFBRs0 were studied. The hydrodynamic characteristics and the energy dissipation of the biological fluidized bed were investigated. Biofilm growth experiments in a pilot-scale AFBR were performed and attached biomass concentration was observed to increase rapidly in the upper part of the bed. The measured and predicted biomass concentrations showed good agreement.
