A process for aerobic operation of fluidized bed reactors with tubular fluidized bodies provided with fins and/or channels on the inside and outside, in which process a dilute aqueous solution of stabilized folic acid is metered into the wastewater to be cleaned, and in which process oxygenous gas is supplied with a ventilation rate (VL) sufficient for aerobic microorganisms, which is defined as the ratio of the amount of air introduced into the fluidized bed reactor per hour in m3/h divided by the cross-sectional area of the fluidized bed reactor in m2, is characterized in that the ventilation rate (VL) is selected such that the microorganisms colonize predominantly only on the inside of the fluidized bodies. |
