| Résumé : |
Sequencing Batch Reactor (SBR) technology was studied to optimize various process control parameters for effective removal of Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) from tannery wastewater. Laboratory scale aerobic SBRs fed with primary treated tannery wastewater were operated at 8, 10 and 12 hour time cycles to study the removal efficiencies of BOD and COD with a view to select a time cycle where maximum removal efficiency was possible. Organic Loading Rate (OLR) was found to be a vital factor in the treatment of tannery wastewater by SBR technology. SBR technology with a 10-hour time cycle and an organic loading rate of 0.21 - 0.24 kg/m3.day was found to be optimum. The BOD and COD removal efficiencies were 85 - 93% and 70 - 75% respectively for 10 hour SBR operation cycle. Other process parameters like Food to Microorganism (F/M), Volumetric Exchange Ratio (VER) and Fill Time Ratio (FTR) were also optimised for the 10-hour time cycle. This research has confirmed the suitability of SBR technology especially for the treatment of wastewater from small-scale tanneries where the wastewater generation is intermittent and the characteristics are fluctuating depending upon the tanning process. |
