Effects of Elevated Atmospheric CO2 Concentration on Phragmites australis and Wastewater Treatment Efficiency in Constructed Wetlands

Original language description

Elevated atmospheric CO2 concentration has been predicted to rise to more than 400 ppm by the end of this century. It has received extensive attention with regard to the pros and cons of eCO2 effects in terrestrial and marine ecosystems, while the effects of eCO2 on wastewater treatment efficiency in constructed wetlands are rarely known. In this study, the atmospheric CO2 concentration was set as 400 ppm CO2 and 800 ppm eCO2. The physiological performance of Phragmites australis and microbial enzyme activities in constructed wetlands in response to eCO2 were tested. Significantly higher net photosynthetic rate and plant growth were found under eCO2. The concentrations of nitrate, total anions, and total ions in the xylem sap of Phragmites australis were reduced, while the uptake of N and P in plants were not affected under eCO2 condition. In addition, the ammonia monooxygenase activity was reduced, while the phosphatase activity was enhanced by eCO2. The increased removal efficiency of chemical oxyg
