Abstract
Flanders is one of the most populated regions in Europe where agriculture is large-scale and intensive. It is therefore challenged by high nutrient loads which deteriorate the surface water quality through direct discharge from wastewater treatment plants and through runoff from agricultural fields. According to our survey, constructed wetlands are in Flanders mainly used to treat domestic and agricultural wastewater in rural areas. The use of constructed wetlands as individual treatment systems has increased in the last years due to the obligation of wastewater treatment at remotely located households. In this overview, the performance of constructed wetlands treating municipal wastewater and manure treatment wastewater is analyzed. In general, the constructed wetlands studied were found to meet the limits set in the Flemish legislation for wastewater effluent quality. Many of the wetlands treating municipal wastewater are, however, dealing with high nitrogen loading which results in low total nitrogen removal efficiency. Also the phosphorus removal capacity in these wetlands was found to be limited. Therefore, these wetlands do not majorly decrease the nutrient discharge to the environment. The constructed wetlands treating manure treatment wastewater are, on the contrary, over-dimensioned and thus able to achieve excellent nutrient removal efficiency.
