摘要： An integrated fixed film activated sludge sequencing batch reactor is provided where both suspended biomass and biomass supported on biofilm carriers are utilized to biologically treat wastewater received by the sequencing batch reactor. The sequencing batch reactor includes two hydraulically connected tanks with suspended biomass being contained in at least one tank and biomass supported on biofilm carriers in the other tank.

摘要： A method of treating wastewater includes removing BOD and ammonium from the wastewater. The wastewater is directed into a tank where it is mixed with mixed liquor or activated sludge from an activated sludge wastewater treatment system. The mixture of wastewater and mixed liquor or activated sludge forms a mixed liquor stream. The mixed liquor stream is directed to a ballasted flocculation system where suspended solids is removed from the wastewater. This produces a clarified effluent that is directed to a zeolite tank. Clarified wastewater from the ballasted flocculation system is directed into the zeolite tank and mixed with zeolite. Zeolite is effective to remove ammonium from the wastewater. Thus, the process as a whole is effective in removing suspended solids, soluble BOD as a result of mixing the mixed liquor or activated sludge with the wastewater, and ammonium.
