Enhanced Photodegradation of Contaminants of Emerging Concern in Constructed Wetlands
Contaminants of emerging concern (CECs) are wastewater derived trace organic compounds such as pharmaceuticals, personal care products, and endocrine disrupting compounds. CECs in surface waters even at low concentrations may lead to long term human health risks and harm the aquatic environment. These compounds are not completely attenuated by conventional biological treatment processes and the cost of removal via advanced treatment is high. Constructed wetlands offer a sustainable alternative for the removal of CECs. Specifically, the direct and indirect photodegradation of CECs has shown promise as a significant mechanism for CEC degradation. Our research group is particularly interested in the indirect photodegradation of contaminants of emerging concern. Indirect photodegradation entails the oxidation of contaminants through the generation of reactive oxygenated species. These reactive species are readily generated through the interaction of sunlight and chromophoric dissolved organic matter. In this presentation we will describe ongoing research at NC State to characterize existing photodegradation capacity in constructed wetlands and develop new insights into the effective design of constructed wetlands to enhance photochemical degradation of contaminants of emerging concern.
