This study investigated the treatment performance and microbial mechanisms of a Natural Composite Oxidation Pond System (NCOPS) designed to treat mixed-source wastewater from pig farming and aquaculture. Water quality monitoring was conducted throughout the operation period to track spatiotemporal variations in key pollutants, including total nitrogen (TN), total phosphorus (TP), nitrate (NO₃⁻-N), nitrite (NO₂⁻-N), ammonium (NH₄⁺-N), and soluble reactive phosphorus (SRP). These data were used to evaluate pollutant attenuation across ponds, calculate removal efficiencies, and link treatment outcomes to microbial community dynamics and functional gene expression.
