<p>The disclosure relates to a method of biologically treating wastewater containing organic matter within a reactor by employing biomass granules comprising: anaerobically treating the wastewater by feeding the wastewater into a lower portion of the reactor at a speed sufficient to mix the wastewater with the biomass granules and form a fluidized bed wherein the biomass granules are fluidized and remove nutrients from the wastewater passing through the fluidized biomass granules while the wastewater is fed into the reactor; after feeding the wastewater into the reactor and forming the fluidized bed of biomass granules, under anaerobic conditions stirring the wastewater and the biomass granules in the reactor, wherein fluidization is maintained during the anaerobic stirring; aerating the wastewater and biomass granules; decanting the wastewater; and discharging treated wastewater having organic matter removed therefrom.</p> |
