The juice that percolates through the hospital sewage and that loads of pollutants must be eliminated. Our study contributes to the establishment of a purification system of hospital wastewater was expensive and effective. The process (stabilization coupled to bio filtration) involves aquatic plants such as Azolla and sand filtration. It thus improves the drainage conditions of the hospital effluents by dramatically reducing the pollution load. This technique decreases and lowers the organic filler according to the conditions imposed. The bio filtration has a specific behavior with respect to the leachate and increases the purification performance of wastewater. So by applying this technique, our study shows a reduction of 77.4% of the chemical oxygen demand (COD), 68.6% of turbidity, 94% of nitrates and phosphates 95% for a residence time of 8 am in the lagoon. This technics following the filter coupling shows a reduction of pathogenic microorganisms. The lagoon level the concentration of organic matter (OM), nitrogen and phosphorus decreased. This study is an important step in the design of a wastewater treatment plant wastewater university clinics in Kinshasa, DRC.

Abstract: (french)
Le jus qui percole aux travers les eaux usées hospitalières et qui se charge des polluants doivent être éliminés. Notre étude contribue à la mise en place d’un système d’épuration des eaux usées hospitalières, eu couteux et efficace. Le procédé (stabilisation couplé à la bio filtration) fait intervenir les plantes aquatiques comme l’Azolla et la filtration sur le sable. Il permet ainsi d’améliorer les conditions d’évacuation des effluents hospitaliers en diminuant considérablement la charge polluante. Cette technique diminue et abaisse la charge organique en fonction des conditions imposées. La bio filtration possède un comportement spécifique par rapport au lixiviat et augmente la performance d’épuration des eaux usées. Ainsi en appliquant cette technique, notre étude montre une réduction de 77,4% de la demande chimique en oxygène(DCO), 68,6% de la turbidité, 94% des nitrates et 95% de phosphates pour un temps de séjour de 8h dans le bassin de stabilisation. Cette technique suite au couplage de filtre, montre une réduction des micro-organismes pathogènes. Au niveau de bassin de stabilisation la concentration en matières organiques(MO), l’azote et le phosphore diminue. Cette étude constitue une étape importante dans le dimensionnement d’une station d’épuration des eaux usées des cliniques universitaires de Kinshasa en RDC.
