CA 2234559

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.

L'invention concerne un procédé de traitement biologique des eaux usées, selon lequel un mélange de boues activées et d'eaux usées subit un traitement gazeux dans un étage (2) d'épuration par boues activées puis les boues activées sont séparées des eaux traitées par flottation (5). Ledit procédé est caractérisé en ce que la concentration des boues activées dans l'étage d'épuration >= 6 g/l et que la flottation est réalisée par relaxation de pression.
