Impact of the Municipal Solid Waste (MSW) Leachate on the Waters. Analysis and Treatment by the Reeds

The proliferation of the wild discharge contributes to the contamination of surfaces and the ground waters by the leachate. This effluent is product of the degradation and the biochemical transformation of the fermentable matter. The subject of this study is to determinate the physicochemical parameters of leachate generated by municipal solid waste in Mostaganem city (western of Algeria). These effluents were to origin of natural treatment by the reeds Arundo donax. The results of analysis show that the leachate is characterized by the presence in strong concentrations of the organic and minerals pollutants. We also raised the presence of heavy metals in considerable quantity. The concentrations of all elements analyzed after the treatment decreased. The reeds could resist to aggressive medium, they develop more by keeping their physical aspect with the appearance of new buds, stems and roots.
