DrècheIndex. décimale : M003310 Résumé : Cette étude a pour objectif d'évaluer la possibilité d'utiliser la drèche de brasserie: un sous produit agro-industriel, comme source de carbone et support de fixation des bactéries dénitrifiantes pour traiter les eaux souterraines chargées en nitrates.
Un bioréacteur à écoulement ascendant a été utilisé pour comparer la performance de la drèche avant et après traitement à l'hydroxyde de sodium en solution.
L'optimisation des paramètres de fonctionnement (TRH, concentration initiale en nitrates, pH) des deux bioréacteurs a montré que les paramètres optimum de la réaction sont: TRH = 100min, NO3- = 200mg/l et un pH = 7,5-7,9 pour le pilote à support non traité et TRH = 55min, NO3- = 200mg/l et un pH = 7,5-7,9 pour le pilote à support traité.
L'étude verticale a montré que le temps de contact et le pH affectent significativement l'élimination des nitrates, alors que la concentration initiale en nitrates est sans influence sur le rendement de dénitrification.
Le présent travail a été réalisé au laboratoire de biotechnologie environnementale et génie des procédés (BIOGEP) comprend trois parties:
- Une partie bibliographique qui regroupe les résultats déjà obtenus lors du traitement de la pollution nitrique en utilisant la dénitrification hétérotrophe.
- La deuxième partie traitera les méthodes utilisées.
- La troisième partie est consacrée aux résultats obtenus et leurs discussions.
- Une conclusion finale.Dénitrification des eaux souterraines par biomasse fixée sur support cellulosique : la drèche [texte imprimé] / Nabil Benyoucef, Auteur ; Abdi, N., Directeur de thèse . - [S.l.] : [s.n.], 2010 . - 70 f. : ill. ; 30 cm. + 1 CD-ROM.
