Constructed Wetland Treatment Plant Constructed Wetland Microbial Fuel Cells
18 This work aimed at determining the amount of energy that can be harvested by 19 implementing microbial fuel cells (MFC) in horizontal subsurface constructed wetlands 20 (HSSF CWs) during the treatment of real domestic wastewater. To this aim, MFC were 21 implemented in a pilot plant based on two HSSF CW, one fed with primary settled 22 wastewater (Settler line) and the other fed with the eff...
متن کاملDynamics of Bacterial Community Abundance and Structure in Horizontal Subsurface Flow Wetland Mesocosms Treating Municipal Wastewater
Dynamics of bacterial community abundance and structure of a newly established horizontal subsurface flow (HSSF) pilot-scale wetland were studied using high-throughput sequencing and quantitative polymerase chain reaction (PCR) methods. Bacterial community abundance increased rapidly within one month and stabilised thereafter in three replicate HSSF constructed wetland (CW) mesocosms. The most ...
متن کاملWastewater Treatment Using Horizontal Subsurface Flow Constructed Wetland
The last few decades witnessed sharp focus on environment pollution and its impact on life in nature. Wetlands can be used for biological treatment of wastewater. Problem statement: Scarcity of water is considered as a global problem and Iran is one the countries which is facing water shortage problem. Pollution of water bodies restrict the availability of water for various uses. Treatment of w...
متن کاملA Hardy Plant Facilitates Nitrogen Removal via Microbial Communities in Subsurface Flow Constructed Wetlands in Winter
The plants effect in subsurface flow constructed wetlands (SSF-CWs) is controversial, especially at low temperatures. Consequently, several SSF-CWs planted with Iris pseudacorus (CWI) or Typha orientalis Presl. (CWT) and several unplanted ones (CWC) were set up and fed with secondary effluent of sewage treatment plant during the winter in Eastern China. The 16S rDNA Illumina Miseq sequencing an...
متن کاملEvaluation of nutrient removal efficiency and microbial enzyme activity in a baffled subsurface-flow constructed wetland system.
In this study, the enzyme activities and their relationships to domestic wastewater purification are investigated in four different types of subsurface-flow constructed wetlands (CWs), namely the traditional horizontal subsurface-flow, horizontal baffled subsurface-flow, vertical baffled subsurface-flow, and composite baffled subsurface-flow CWs. Results showed that the urease activity in the c...
