Biologische Abwasserreinigung bei hohen Schlammkonzentrationen
摘要
The invention concerns a biological sewage-treatment method in which gas is first passed through a mixture of sludge and sewage in an activation stage (2) and the activated sludge then separated from the treated sewage by flotation (5). The method is characterized in that the concentration of the sludge in the activation stage is >/= 6 g/l and that flotation is achieved by pressure release.
