摘要

A liquid stage, or its hydraulic equivalent, is maintained in an activated sludge system where incoming waste water and recycle sludge are initially mixed. Both the dissolved oxygen and the steady state BOD are maintained at or above minimal concentrations critical to promote the selective growth of active, rapidly settling, non-filamentous biomass thereby inhibiting or precluding the development of filamentous biomass of higher surface area.
