Traitement des lixiviats de la décharge contrôlée du Grand Agadir par aération intensive
The objective of this work is to develop a technique for the treatment of leachate seeping from landfill of the Greater Agadir. Since its opening in 2010, the landfill produced huge quantities of leachate stored in large ponds because its pollution load does not allow the discharge into the receivin...

The objective of this work is to develop a technique for the treatment of leachate seeping from landfill of the Greater Agadir. Since its opening in 2010, the landfill produced huge quantities of leachate stored in large ponds because its pollution load does not allow the discharge into the receiving environment without adequate treatment. In this work, the aeration is used to reduce the pollution load of leachate seeping from fresh household waste in the Greater Agadir landfill. The treatment of effluents with high organic load by air injection is a technique that has given different results depending on pollution load and the chemical nature of inorganic constituents. The leachates underwent air injection at 7 L/min over a period of two months. This technique has lead to remarkable treatment efficiency with reductions of 99.3% of COD; 99.1% of BOD5; 94.4% of total nitrogen and 82.9% of suspended matters, knowing that the initial concentrations were respectively 72,000 mg/L, 44,000 mg/L, 1.260 mg/L and 12,560 mg/L. |
