Abstract:
The challenges that we must address have to do with the implementation of the knowledge and technology existing in the world around the issue of water, environmental pollution and climate change; for the preservation and conservation of our natural resources. In this research, an activated sludge system was studied for the treatment of waste water with a high concentration of phenol for reuse, varying the hydraulic retention time and the concentration of dissolved oxygen. The results showed the best COD removal rate (55%) and phenol biodegradation (49%) during experiment IV, at a waste water dilution rate of 25% (v/v), dissolved oxygen (DO) feed. ) of 1.5 ppm, hydraulic retention time (HRT) of 2.81 days and organic load (Bv=7.5kgCOD/m3.d), once the biomass was acclimated to the presence of phenol as the only carbon source, in previous experiments.
