Abstract:

The present work deals with the leachate treatment using the following processes: oxidation by the bleach. This treatment is preceded by a precipitation using NaOH. The adsorption by bark Alep pine powder and fibers of date palm leaves is used in the second part of the work. Monitoring of physicochemical parameters of that leachate gave a pH of 8.46; an electrical conductivity of 18.24mS/cm, an orthophosphate concentration of 0.35mg/l, an oxidability of 125mg O2/l and a turbidity of 252FAU. Pretreatment with precipitation was considered. The aim is to reduce the pollution in the leachate. Then, oxidation tests reduce the leachate turbidity to 48FAU, as a dose of the bleach of 0.29g/l. Using adsorption for leachate treatment requires the least investment cost. Adsorption with 2g of Alep pine bark/100ml of leachate gave the best results of turbidity. However, an additional treatment is required to reduce turbidity as minimum as possible.
