In a biological process available for the treatment of industrial wastewater, especially for the treatment of wastewater discharged from the petrochemical industries, it would be the most difficult problem to prepare the activated sludge which decomposes or assimilates synthetic compounds in wastewater. There is an acclimation process of obtaining activated sludge useful for the wastewater treatment, but this process is less reproducible.In the present study, a new concept was introduced into the preparation of a specially activated sludge which stimulates the microorganisms into strong activities of decomposing or assimilating the synthetic organic compounds contained in wastewater together with the ordinary activated sludge in a commensal state. Corynebacterium nitrilophilus can grow on nitrile compounds such as acetonitrile, propionitrile, butyronitrile, succinonitrile, and adiponitrile, In this study, this species as a commensal microorganism and the specially activated sludge as a model sample of the new concept, which can assimilate nitrile compounds, were used.
