Abstract

Provided is a biological processing method for organic sewage. An aeration tank performing an active sludge processing is divided into a raw water inlet section and a section in a downstream side of the raw water inlet section. A microorganisms-adhered member is dipped in the raw water inlet section, and the BOD volume load of the microorganisms-adhered member is set to be 1 kg/(m<3>‧day) or more.
