Description
Summary:This study focused on assessing the effectiveness of vertical subsurface constructed wetlands (VSFCW) in purifying integrated poultry and aquaculture wastewater (PAW) in a tropical region. This evaluation encompassed the treatment of physico-chemical, heavy metal, and microbiological pollutants across three distinct climatic seasons and hydraulic retention time (HRT: 21 days). Parameters such as BOD (29.50 mg/L), COD (56.67 mg/L), Zn (2.97 mg/L), Cr (0.24 mg/L), Cu (1.78 mg/L), Pb (0.21 mg/L), total fecal coliform (866.67 cfu/mL), total coliform (1666.67 cfu/mL), E. coli (1133.33 cfu/mL), and Salmonella/Shigella (700 cfu/mL) exceeded the discharge limits for wastewater into nearby surface water bodies. Significant removal efficiencies were observed for all parameters tested in the CW planted with both Phragmites karka and Typha latifolia. The macrophytes showed similar removal efficiencies for all tested parameters, and there was no significant difference in the initial concentrations of the parameters based on the experimental season, except for microbial properties. This suggests that weather conditions did not significantly impact the concentration of physical and chemical properties in the wastewater. Consequently, this study successfully demonstrates the potential of using a VSFCW for effective treatment of PAW. Leveraging the power of nature's green allies, Phragmites karka and Typha latifolia, a Sub-surface Constructed Wetland becomes a dynamic and efficient solution. This innovative strategy not only effectively addresses the wastewater challenge but also promotes sustainability and ecological balance. By harnessing the extraordinary capabilities of these wetland plants, the integrated system showcases its potential to transform waste into a valuable resource while minimizing the environmental footprint. In a world that demands sustainable solutions, this pioneering approach paves the way for a greener future in wastewater treatment for Integrated Poultry and Aquaculture industries.
