constructed wetland-microbial electrolysis cell system metagenome

A constructed wetland coupled with a microbial electrolysis cell (CW-MEC) is considered as a new process with broad prospects. It is necessary to further investigate and optimize CW-MEC. Therefore, we investigated the comprehensive effects of fulvic acid on the conventional constructed wetland and the emerging wetland.Microbial samples were collected from the cathode and anode before and after the start of the experimental period for metagenome.
