| Résumé : |
The purposes of this study were to determine the ability of an activated sludge system to treat wastewater containing Para-Nitrophenol, (PNP), and to evaluate the effect of a commercially available “bioaugmentation product” on the performance of an activated sludge unit treating wastewater containing PNP.
The activated sludge system was simulated using two-liter operated reactors seeded from a municipal wastewater treatment plant. Various experimental comparisons were made on units exposed to PNP, not exposed to PNP, and units exposed to PNP while undergoing bioaugmentation.
Results show that the batch activated sludge units were able to adapt to and degrade PNP up to concentrations of 113 mg/l in the mixed liquor. The presence of PNP interfered slightly with the performance of the batch units in terms of solids production, effluent suspended solids, and sludge volume index.
The results of this study also indicate that the addition of the bioaugmentation product improved batch activated sludge operation in terms of PNP degradation, COD reduction, effluent suspended solids, and solids production. A similar improvement in PNP degradation was obtained by the addition of small amounts of fresh activated sludge microorganisms from a municipal wastewater treatment plant.
