Abstract
L'invention a pour objet un procédé de traitement d'une eau résiduaire contenant NH3 . Il consiste à introduire à un pH d'environ 8,5 à 11,5 l'eau résiduaire 1 dans un réacteur 12 pour soumettre cette eau à une oxydation par voie humide avec un gaz contenant de l'oxygène et en présence d'un catalyseur tout en maintenant l'eau résiduaire à une température d'environ 100 à 370 degrés C et sous une pression permettant à cette eau de rester en phase liquide, et à introduire dans ce réacteur une substance alcaline 21. Traitement notamment des eaux résiduaires en provenance des installations métallurgiques et chimiques pour rendre possible l'évacuation dans la mer ou autre étendue d'eau.The subject of the invention is a process for treating waste water containing NH3. It consists in introducing, at a pH of approximately 8.5 to 11.5, the waste water 1 into a reactor 12 in order to subject this water to wet oxidation with a gas containing oxygen and in the presence of a catalyst while maintaining the waste water at a temperature of about 100 to 370 degrees C and under a pressure allowing this water to remain in the liquid phase, and to introduce into this reactor an alkaline substance 21. Treatment in particular of the waste water in from metallurgical and chemical installations to make it possible to discharge into the sea or other body of water.
