Abstract
L'invention concerne le réglage de l'adduction de la DBO à une étape de dénitrification par voie automatique, dans une épuration biologique des eaux résiduaires. Le réglage est basé sur une analyse continue de la teneur en nitrite et en nitrate, laquelle analyse comprend les phases : a. retirer et filtrer un courant continu-échantillon des eaux résiduaires ; b. convertir sélectivement tout le nitrite en nitrate ou inversement; c. déterminer sélectivement par voie spectrophotométrique la teneur en nitrite ou en nitrate; d. convertir le signal obtenu à l'aide d'un régulateur proportionnellement intégrant en un signal vers l'adduction de la DBO; e. ajuster régulièrement au zéro l'appareil d'anlyse alors que, du moins pendant une partie du temps nécessaire à ce sujet, l'appareil est shunté et le l'adduction de la DBO est maintenue pendant ce temps à une valeur constante la dernière mesurée. Le réglage est appliqué dans un procédé pour l'épuration biologique en étapes des eaux résiduaires dans laquelle épuration les eaux sont dénitrifiées dans la dernière étape.
