METHOD AND SYSTEM FOR TREATING WASTEWATER IN AN INTEGRATED FIXED FILM ACTIVATED SLUDGE SEQUENCING BATCH REACTOR

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.
