Despite the increasing concern about impacts of microplastics on wastewater treatment, underlying mechanism by which affect nitrous oxide (N2O) accumulation during denitrification is still underexplored. In particular, effects biodegradable (BMPs) sewage sludge systems are largely overlooked. Previous studies often used one type polymer as model microplastics, far from a real-world scenario various occurring simultaneously. This work assesses toxic influences chronically adding four typical BMPs versus conventional nonbiodegradable (NBMPs) to denitrifying sludge. Our results showed that both and NBMPs suppressed performance, intensified electron competition, regulated distribution, consequently promoted N2O at chemical oxygen demand:nitrate ratio <4:1. Importantly, more severe were observed in reactor with BMPs. A subsequent mechanistic study revealed significantly decreased relative abundances denitrifiers key genes involved transport consumption system (ETCS), might be related varied extracellular polymeric substance components. contrast, damaged bacterial membranes directly caused dead cells overproducing reactive species, hence disrupting ETCS. Overall, this suggested wastewater, especially BMPs, could disrupt potentially increase greenhouse gas emission.
