Résumé

Abstract
The water pollution in the world poses a real public health problem. Indeed, the rarity of the source and degree of pollution are responsible for numerous health disasters. Thus, the wastewater reclamation becomes a primary parameter in environmental research. It is in this way that our research is undertaken, it relates to the purification of wastewater by Phragmites australis in arid and batch culture. The results obtained allow us to see the changing in environmental parameters (temperature, pH, dissolved oxygen) that influence the performance of purifying sewage systems and other parameters of the reduction in pollutants (MIS, OCR, Nitrogen, Phosphorus and bacterial contamination of fecal mass). Thus, using the model Phragmites australis in treatment ponds, thus allows the stratification of the water body and the homogenization temperature of the basin, the decrease in pH by one unit in the sewage two weeks of cultures, eliminating between 54 and 70% of ammonia nitrogen for initial expenses above 50 mg/L and finally, the reduction of 100% of E. coli and fecal streptococci.
Key words: Phragmites australis - Biological purification - MIS – OBR5- OCR - Batch culture.
