Design of Subsurface Flow Constructed Wetlands

Quick answer：

Subsurface flow constructed wetlands are a type of wetland treatment system that utilizes the natural processes of soil and plants to treat wastewater. They are designed to mimic natural wetlands, with the wastewater flowing through a layer of soil and plant roots. This design allows for the removal of nutrients, organic matter, and pathogens from the wastewater, making it a cost-effective and sustainable solution for wastewater treatment.
