Abstract

A biological sewage treatment for the conversion and separation of nitrogen by nitrification and denitrification is based on an anaerobic region in a pre-clarification basin and at least one aerobic basin for activated sludge, followed by a final settling basin. Ten to fifty percent of the effluent is extracted below the water level of the final settling basin during dry weather and is recycled via a buffer basin to the inflow before the preclarification basin.
