Deeper investigation on methane generation from synthetic wastewater containing oxytetracycline in a scale up acidic anaerobic baffled reactor

Acidic anaerobic digestion attracted much attention and interest due to its significant advantage in wastewater treatment. In the present study, methanogenic fermentation was successfully operated under acidic condition during treating containing oxytetracycline (OTC) a scale up baffled reactor (ABR). After start-up process, pH value first compartment 4.60 with high activity of methanogenesis. stabilization, different OTC loading 1.0, 3.3 5.0 g/m3/d added influent for removal. The resulted showed that addition had little impact on methane generation whole COD removal rate 95% 60%, respectively. microbial analysis, could significantly influence bacteria archaea communities. To be more specific, Methanosaeta highest relative abundance tolerance condition. work supplied deeper insights into from
