Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands, Modeled in Modelica
2005 (English)Conference paper (Refereed)
The global problem of eutrophication, the enrichment of water bodies by nutrients, has inrecent years resulted in an increased interest in non-conventional ways to reduce the amount of nutrients discharged into the environment. One of the more commonly proposed and also used solutions is to append artificial or constructed wetlands as a final step in the treatment of wastewater. However, both the construction of the wetlands and the maintenance thereof are time and resource consuming, hence a high production and maintenance cost. Due to these high costs, tools for modeling and simulation have turned out to be valuable asset in the development of constructed wetlands.
In this paper, two ecological models of nitrogen processes in treatment wetlands have beenmodeled, simulated, and visualized using the Modelica language. The results show that nitrogen decrease in a constructed treatment wetland can well be simulated using the Total Nitrogen or the Nitrification/Denitrification model expressed in Modelica and the MathModelica Model Editor.
