摘要

Constructed wetlands (CW) represent a promising technology for wastewater treatment, particularly in urban areas of developing countries. Previous studies have demonstrated the effectiveness of modified constructed wetlands (mCW) in meeting desired treatment standards, yet further investigation into their pollutant removal mechanisms is essential. Microbial communities within CWs play a pivotal role in pollutant degradation and removal, orchestrating vital processes such as decomposition, nitrification, denitrification, and phosphorus removal. This study aimed to characterize microbial communities within the layers of small-scale mCWs, elucidating their roles in pollutant treatment. Results indicated remarkable efficiencies in contaminant removal, with total chemincal oxygen demand (TCOD) and biological oxygndemard (BOD5) removal rates averaging approximately 72.7% and 87.6%, respectively, and nutrient parameters achieving removal efficiencies of 87.2—88.9%. Microbial analysis revealed Proteobacteria as the predominant phylum across all samples, showcasing diverse metabolic capabilities essential for wastewater remediation. Notably, Nitrospirae emerged as a dominant phylum, indicating consistent microbial activity throughout the CW system. These findings underscore the efficacy of small-scale mCWs in promoting efficient pollutant removal and highlighting the critical role of microbial communities in enhancing wastewater treatment processes.
