摘要：
In this study optimal operational parameters for carbon and nitrogen removal (specifically dissolved oxygen concentrations in different zones, hydraulic retention time and flow velocity) for wastewater typical for the Moscow region (low C/N and C/M ratio) in the Oxidation Ditch have been determined. The processes of nitrification and carbon oxidation in the studied system were stable. The possibility of simultaneous denitri-nitrification in the Lab-scale Oxidation Ditch with Low C/N ratio has been proved. The results of this study will be used in further researches.
