- Abstract:
- Pharmaceuticals and personal care products (PPCPs) are frequently detected in effluent of wastewater treatment plant due to their inadequate degradation during conventional biological treatment processes. In this study, a lab?scale bioelectrochemically assisted vertical flow constructed wetland (E-VFCW) system was developed to evaluate its efficacy in degrading and removing PPCPs from secondary effluent. Without the need for external carbon sources or chemical additives, the E-VFCW enhanced the removal of organic pollutants through integrated bioelectrochemical and plant-microbial interactions, achieving advanced and efficient purification of multiple pharmaceutical pollutants. Microbial community analysis revealed significant enrichment of key functional and electroactive microbes, including Longilinea, Aquimonas, and Flavobacterium. This technology provides a promising solution for controlling pharmaceutical pollution in low C/N ratio wastewater, demonstrating the considerable potential of bioelectrochemical systems in sustainable wastewater treatment.
