Title (DE) VERFAHREN ZUR AUFARBEITUNG STICKSTOFFBELASTETER ABWÄSSER
(EN) METHOD FOR PROCESSING WASTE WATER LOADED WITH NITROGEN
(FR) PROCÉDÉ DE RETRAITEMENT D'EAU USÉE CHARGÉE EN AZOTE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Reinigung eines mit stickstoffhaltigen Verbindungen belasteten Abwassers, wobei das mit stickstoffhaltigen Verbindungen belastete Abwasser mit einem smektitischen Schichtsilikat umgesetzt wird, wobei ein mit stickstoffhaltigen Verbindungen beladenes Tonmaterial erhalten wird, und das mit stickstoffhaltigen Verbindungen beladene Tonmaterial abgetrennt wird, wobei ein gereinigtes Abwasser erhalten wird.
(EN) The invention relates to a method for cleaning waste water loaded with compounds containing nitrogen, wherein the waste water loaded with compounds containing nitrogen is reacted with a smectitic sheet silicate, wherein a clay material loaded with compounds containing nitrogen is obtained, and the clay material loaded with compounds containing nitrogen is separated, wherein cleaned waste water is obtained.
(FR) L'invention concerne l'épuration d'une eau usée chargée en composés contenant de l'azote, ledit procédé consistant à faire réagir l'eau usée chargée en composés contenant de l'azote avec un silicate lamellaire smectique, à obtenir une matière argileuse chargée en composés contenant de l'azote, et à séparer la matière argileuse chargée en composés contenant de l'azote, en conséquence de quoi on obtient une eau usée épurée.
