Abstract

Leachate from landfill requires treatment before discharge into the environment to avoid surface and underground water contamination. In this paper, the treatment performance of combined system by physico-chemical and biological techniques for landfill leachate are studied, the biological treatment by Sequencing Batch Reactor (SBR), the coagulation-flocculation and the filtration-fly ash. Both coagulation-floculation and treatment biologique by Sequencing Bach Reactor are effective for over 98,07% COD removal, 99,16% BOD_5,a removal rate of 96,14% for NH₄, 79,82% for NO₃^-, 97,32% for NO₂^-, 89,09% for suspended solids (SS) and 87,71% for PO₄. A combination of physical and biological treatments has demonstrated its effectiveness for the treatment of intermediate leachate. Almost complete removal of COD and nitrogenous forms has been accomplished by a combination of biological treatment by SBR and physical treatment by filtration with COD concentration of 5200 mg/L and BOD₅ concentration of 1375,12 mg/L. It is important to note that the selection of the most suitable treatment method for landfill leachate depends on the characteristics of landfill leachate, technical applicability and constraints, effluent discharge alternatives, cost-effectiveness, regulatory requirements and environmental impact. As a whole, a combination of two treatments proves to be more efficient and effective than individual treatment. This could be because a two-step treatment has the ability to synergize the advantages of individual treatments, while overcoming their respective limitations. A combined treatment is indeed capable of improving the effluent quality and minimizing the residue generated than an individual treatment.
