Subsurface wetlands (SW) effectively treat low-contaminant water, but struggle with high loads like domestic wastewater. Improving air transfer, particularly through free drainage, is crucial for enhancing nitrogen and phosphorus removal in single-stage wetlands.

Area of Science:

  • Environmental Engineering
  • Water Treatment Technologies
  • Wetland Systems

Context:

  • Subsurface wetlands (SW) are utilized for wastewater treatment.
  • The study investigates the limitations of SW in treating high-strength domestic wastewater.
  • Oxygen supply mechanisms, including root oxygenation and water-carried oxygen, are examined.

Purpose:

  • To analyze the contribution of root oxygenation, water-carried oxygen, and plant nutrient uptake in SW.
  • To evaluate the effect of free drainage on air transfer and treatment efficiency.
  • To determine the limitations of SW for domestic wastewater and explore air-reoxygenation strategies.

Summary:

  • Plant roles are significant in SW treating low-contaminant surface water, maintaining aerobic conditions and stable nutrient removal.

  • For high-load domestic wastewater, root oxygenation is limited (<20%), leading to anaerobic conditions and poor nitrogen removal (<20%).
  • Phosphorus removal decreases significantly over time due to saturation of adsorption capacity. Free drainage significantly improves nitrogen removal.

    • Impact:

    • SW face limitations with high pollutant loads, necessitating air-reoxygenation strategies.
    • Proper air transfer management, especially free drainage, can achieve high total nitrogen removal in single-stage wetlands.
    • Findings highlight the importance of substrate aeration and drainage design for optimizing SW performance in domestic wastewater treatment.
