Performance Evaluation of Anaerobic Biodegradation of Synthetic Phenolic Waste Water in Single Stage Fixed Bed Bio- Reactor

Dr. Mishu Singh

Abstract: Biological treatment systems are supposed to be advanced in the sense that they are more effective and involve a greater degree of stabilization of waste. The treatment of toxic and inhibitory phenolic compounds using biological techniques have been pursued vigorously as a promising and widely accepted treatment process due to its ease of handling and properly operated to prevent the production of secondary pollutants. Upflow anaerobic bioreactors (UAFB) have been widely used for the treatment of high organic load industrial wastewater. The treatment of synthetic phenolic wastewater by a single stage anaerobic fixed bed bioreactor with granite stones packing at a temperature of 300C, 350C, 400C and 450C was studied. A recirculated single stage up-flow anaerobic bioreactor was operated at all the above-given temperatures with initial BOD 1462 mg/l and initial COD 5720 mg/l for a digestion period of 25 days with a working volume of 1000 ml. The performance of the reactor was monitored after every five days and analyzed in terms percentage COD, BOD, TS, TDS, VS removal and biogas production. The removal efficiency of BOD, COD, TS, TDS and VS could reach to a maximum value of 63.20 %, 61.24 %, 44.88 %, 47.67 % and 53.12 % respectively. The result showed that the maximum biogas production in the reactor reached 0.0077 liters /liter /day at a temperature of 400C
