The leachate is a source of contamination of surface water and groundwater if not pretreated. Indeed, its complex structure and pollutant load makes treatment very difficult to meet the limits required by the standards.
The study presented in this work aimed to develop techniques for treatment of leachate. Two techniques were studied. The first involves treatment by electrocoagulation with aluminum electrode, the second is a sand filter with a diameter between 0.44 and 0.55 mm. Initially, we characterized the sample in the rough. Thereafter, we followed the evolution of abatement of chemical oxygen demand (COD) levels, biological oxygen demand (BOD5), suspended solids (TSS). Secondly, we performed a comparative study on the germination of seeds of sorghum and Lucernes by use of leachate unprocessed or processed and at different concentrations. Treatment of leachate by electrocoagulation-filtration significantly reduced the intensity of their color that resulted in a decrease in pollution load of mineral and organic matter, especially in color, BOD5 and COD. This, allowed him to act favorably on the germination of seeds of sorghum and Lucernes. Leachate treated at different concentrations has no effect on the germination of Sorghum and Lucernes. The application of the raw leachate to inhibit germination of the total grain examined.

Abstract: (french)
Le Lixiviat est une source de contamination des eaux de surface et des eaux souterraines s'il n'a pas subi un traitement préalable. En effet, sa structure complexe et sa charge polluante rendent son traitement très difficile pour atteindre les limites exigées par les normes. L'étude présentée dans ce travail avait pour objectif la mise au point des techniques de traitement des Lixiviats. Deux techniques ont été étudiées. La première consiste à un traitement par électrocoagulation avec l'électrode d'aluminium, la deuxième consiste à une filtration à sable ayant un diamètre variant entre 0,44 et 0,55 mm. Dans un premier temps, nous avons caractérisé l'échantillon à l'état brut. Par la suite, nous avons suivi l'évolution du taux d'abattement de la demande chimique en oxygène (DCO), de la demande biologique en oxygène (DBO5), Matières en suspension (MES). Dans un deuxième temps, nous avons réalisé une étude comparative sur la germination des graines des Sorgho et des Luzernes par utilisation des Lixiviats à l'état brut ou traité et à différentes concentrations. Le traitement des Lixiviats par électrocoagulation-filtration a nettement réduit l'intensité de leur couleur qui s'est traduit par une diminution de leur charge polluante en matière minérale et organique, notamment en couleur , DBO5 et DCO. Ceci, lui ont permis d'agir très favorablement sur la germination des graines des Sorgho et des Luzernes. Les lixiviats traités à différente concentration n'ont pas d'effet sur la germination des Sorgho et des Luzernes. L'application des lixiviats à l'état brut inhibe la germination totale des grains étudiés.
