Description: Das Projekt "Zum Verhalten von anorganischen Verbindungen in unterschiedlichen bepflanzten Bodenfiltern/Planzenkläranlagen" wird vom Umweltbundesamt gefördert und von Universität Halle-Wittenberg Zentrum für Ingenieurwissenschaften durchgeführt. Constructed wetlands (CWs) are valuable systems for treatment of various types of wastewater. Different processes take place in CWs and contribute to the removal of the contaminants. Due to the associated high degree of complexity, our understanding of the processes and their interactions is still incomplete. In addition, the dynamics of sulphur cycle processes in CWs are not well understood. The occurrence and intensity of dissimilaotry sulphate reduction and its consequences on the other treatment processes in different types of CWs will be investigated. Furthermore, the mechanisms of reoxidation of reduced S species and the significance of the different intermediately oxidized S species will be explored. Besides, the effects of the hydraulic characteristics of the CW on the S cycle processes will be inspected. Moreover, the toxic effects of sulphides on different species of wetland plants will be studied. Additionally, the processes of sulphide removal in CWs will be examined. It is expected to gain a better understanding of S transformations in CWs and its impacts on treatment performance, which in turn will lead to design optimization and costs saving; and to obtain more confident performance expectations. This will consequently provide for decreasing and controlling the eventual pollution loads that will be disposed to the environment. This is highly beneficial for future application not only for developing, but for transitional and developed countries as well.
