抄録

In wastewater treatment by fluidized-bed bioreactor with polyurethane support particles, the influence of seed microbes on treatment characteristics has been investigated experimentally. In consequence, it was shown that the organic substrate concentration in the effluent and amounts of retained and suspended microbes show respective specific time-dependent variations in the day course from initial to steady stage, regardless of growth history of seed microbes. But these variation processes with unacclimated microbes were found to be retarded in direct proportion to day course when compared with processes with acclimated microbes. This was caused by the presence of an induction phase and related delay in the protozoa growth rate.
