Abstract
This paper highlights the potential of per-oxidation pretreatment to petrochemical waste water (PWW) prior to anaerobic co-digestion process was analyzed in continuous stirred tank reactor (CSTR) continually with dairy cattle and beef cattle manure. Biodegradability index (BOD/COD) was elevated up to 35%by Oxidation by hydrogen peroxide (OHP). As long asCSTR ran with non-OHP PWW, system was found to be failed at organic loading of 6.5-12.99 kg COD/m3/d by reason of vigorous volatile fatty acid accumulation. Conversely, the OHP PWW effected sustainable superior TCOD removal at 6.03-11.7 kg COD/m3/d organic loading with impervious process stability at co-digestion period. While methane production is deliberated to be inhibited due to volatile fatty acid (VFA) accumulation leading to reactor instability during anaerobic digestion, the co-digestion of OHP pretreated PWW reproduced boosted methane yield, followed by 98±0.5%, 95±0.05% and79±0.06% COD reduction at 9, 6 and 4 days HRT. The concrete data disclosed that prolonged HRT and abridged cycle time (CT) brought intensified TCOD removal efficiency and methane yield.
