Lagunage naturel de lixiviat de décharge

Abstract: Dans le cadre d'un traitement par lagunage naturel des lixiviats d'une décharge d'ordures ménagères broyées, nous avons procédé au cours d'un cycle annuel (mai 1998 à mai 1999) à des analyses biologiques et physicochimiques des eaux à l'entrée (lixiviat brut), dans les quatre bassins successifs et à la sortie du dispositif (lixiviat traité) avant son rejet dans le milieu récepteur (ruisseau Mont Bonnet). L'évolution spatiotemporelle de la qualité des lixiviats a été approchée par le suivi des fluctuations sais… Show more

“…Some authors have recorded an average temperature of 29.8˚C [3], close to the average of this study results. The temperature depends on climate conditions [4]. To evaluate the characteristics of a treatment, temperature is an important parameter as far as the kinetic of bacteria and biological activity is dependent on climatic conditions.…”

“…• Le choix du modèle de notre réacteur de UASB a donné satisfaction pour le traitement d'une quantité de 1/10 de la quantité produite journalièrement ce qui va nous donner une idée sur le dimensionnement de notre réacteur UASB pour le traitement de ces effluents a forte charge organique (Trebouet et al, 1998 ;Khattabi et al, 2002) et avoir un écoulement de traitement permanant.…”

“…• The choice of UASB reactor model was satisfactory for treating an amount of 1/10 of the daily produced amount. This model results would be useful to design an UASB reactor which have a permanent processing flow and can treat effluent with high organic load [4,35]. At this stage, the current study did not go beyond these observations, but it opens interesting perspectives such as: Determination of UASB reactor dimensions and optimum temperature in order to reach a reduction yield higher than 95%; Combination of UASB technique and forced evaporation technique, investigation currently in progress, to determine possible use of produced gases for heating during the cold season and have a material evaporation performance.…”
