BEIJING, 26th October, 2022 (WAM) -- Chinese researchers have discovered that a new type of constructed wetland can not only enhance water purification efficiency but also control gaseous emissions, Chinese news agency, Xinhua, reported.The researchers from the Northeast Institute of Geography and Agroecology under the Chinese Academy of Sciences have combined microbial fuel cells (MFCs) with constructed wetlands (CWs) based on the principles of electrochemistry and microbiology.Thereafter, they quantitatively compared the pollutant removal efficiency and the emission of multiple gases between MFC-CWs and the traditional...
