Abstract

L'invention concerne une méthode de suppression des polluants atmosphériques contenus dans la lessive générée par un procédé de préparation de pâte, la méthode consistant à injecter un gaz contenant de l'oxygène dans ladite lessive et de condenser la vapeur d'eau générée par le gaz de séparation de manière à produire un condensat contenant les polluants.
