Performances d'un biofiltre à garnissage plastique pour le traitement d'effluents fortement contaminés en phénol, cadmium et chrome

Abstract: The presence in domestic wastewater of high concentrations of organic and inorganic contaminants represents a serious problem for the treatment of these effluents. This research aimed to establish the performance of an aerobic biofiltration system with plastic packing for the treatment of effluents having high concentrations of phenol (300–500 mg·L–1), Cd(II) (2.5–10.0 mg·L–1), and Cr(III) (5.0–20.0 mg·L–1). Six biofilter units were first started in batch mode and then operated in continuous mode under similar… Show more

“…It was already practiced in Massachusetts (USA) in the late 1800s [BERNIER et al 2001;LIÉNARD, RACAULT 2003]. Wastewater treatment using filtration on granular natural media, such as sand filters, could be an effective method to meet water quality requirements for reuse applications [AL-JLIL et al 2009;KAUPPINEN et al 2014], those media allow the retention of particles, and the fixation of the biomass developed on the granular material, but also, the biodegradation of phosphorus and organic pollutants as well as physical filtration [HUA et al 2003;ZIDANE et al 2006]. The microorganisms are immobilised on the filling material in the form of a biofilm.…”

“…Les procédés traditionnels de traitement de l'eau usée, tels que les procédés biologiques donnent des résultats non satisfaisants (Pillre, 2001 ;Zidane, 2006). Ainsi la principale contrainte d'utilisation de cette méthode provient de la difficulté d'accumuler des bactéries à certains effluents et leur inhibition par certaines composantes chimiques et aussi, la duré de traitement (Alinsafi et al, 2005).Pour cette raison, des nouvelles recherches sur des nouvelles méthodes.…”

“…Pour cela, des granules aérobies ont été obtenus à partir d'un surnageant de boues activées, et puis acclimatés au phénol dans un réacteur du type SBR. L'acclimatation est censée augmenter le potentiel de biodégradation des granules, car les populations issues de boues activées peuvent s'acclimater aux composés phénoliques avec succès (Zidane et al, 2006). Ensuite, la cinétique de biodégradation a été étudiée à des différentes concentrations initiales de phénol (40–1112 mg/L).…”
