Abstract
A wastewater treating system includes: a vessel defining a vessel space therein, the vessel space being partitioned into an activated sludge zone that is adapted to receive waste water and a body of an activated sludge therein, and a coarse filtering zone that is disposed downstream of and that is in fluid communication with the activated sludge zone for receiving bio-treated wastewater from the activated sludge zone; and a bed of biomass carriers colonized with microorganisms and disposed in the coarse filtering zone for further bio-treating the bio-treated wastewater from the activated sludge zone and for separating coarse suspended solids from the bio-treated wastewater in the coarse filtering zone.
