Abstract

L'invention concerne un procédé de purification d'eaux résiduaires domestiques, industrielles ou mélangées. Ledit procédé consiste à établir dans un bassin d'activation d'un premier étage biochimique des conditions aérobies assurant une dégradation telle des substances organiques qu'une formation de bactéries filiformes et un gonflement de la boue activée soient empêchés. Application au traitement des eaux résiduaires de toute origine.
