macrophytes, nitrogen removal, constructed wetlands
In constructed wetlands, macrophytes and bacteria are considered the drivers of nitrogen removal. Understanding how well macrophytes contribute to nitrogen removal and the influencing factors can be used as a design consideration for the improvement of these systems. This study investigated the nitrogen removal through uptake by Cyperus alternifolius and Typha angustifolia in constructed wetlands. Cyperus alternifolius and Typha angustifolia contributed 2.87% – 15.9% of the total nitrogen removal under slightly stressed conditions in the constructed wetlands when the plants were slightly stressed by high concentrations of ammonia.
