Abstract

La présente invention concerne la mise en œuvre d’une colonne à bulles pour le traitement de l’air contenu dans et/ou entrant dans et/ou sortant hors d’un espace confiné pour l’appauvrir en composés gazeux polluants, notamment en NOx, SOx et/ou COV, et en particules solides. La colonne à bulles (100) comporte une enceinte, préférentiellement cylindrique, de rapport H/D ≤ 1,5 (H : hauteur, D : diamètre), remplie de liquide apte à capter lesdites particules et composés gazeux polluants. L’air est injecté dans le liquide au fond de l’enceinte (1) de manière à former des bulles, et selon un débit tel que la vitesse superficielle de gaz opérationnelle Ug allant de 0,35 à 0,50 m/s. L’air sous forme de bulles est ainsi traité par contact avec le liquide de sorte qu’au moins une partie des particules et/ou du ou des composés gazeux polluants est captée par le liquide, et l’air traité est évacué en haut de l’enceinte.
