Abstract

La présente invention concerne un dispositif de purification d'eaux usées contenant des impuretés, monté ou pouvant être monté dans un bateau. Ce dispositif comporte au moins un réacteur (10) pouvant être raccordé à un réservoir d'eaux usées (6) servant au stockage provisoire des eaux usées. Les eaux usées sont mélangées et enrichies avec du gaz dans ledit réacteur et une décomposition biologique intervient. Le dispositif comporte également une unité de séparation (18) qui est raccordée au réacteur (10) et sert à retenir les éventuelles impuretés résiduelles. La particularité de l'invention réside dans le fait que le réacteur (10) est conçu pour être intégré au moins partiellement dans le réservoir d'eaux usées (6) et qu'il constitue une unité sensiblement autonome, fermée par rapport à l'espace intérieur environnant du réservoir d'eaux usées (6).
