Seasonal dynamics of plant sediment microbial fuel cell efficiency in a moderate continental climate zone

  • 1 Faculty of Geology and Exploration – University of Mining and Geology, Bulgaria

Abstract

Plant sediment microbial fuel cells (PSMFC) transform solar energy in an environmentally friendly and efficient way. Their integration in constructed wetlands allows the generation of electricity in parallel wastewater treatment. The work of plant sediment microbial fuel cells is influenced by a number of factors, such as environmental conditions, vegetation type, hydraulic retention time, water flow, the presence of heavy metals and other contaminants in the treated water and others. The purpose of this study is to establish the seasonal dynamics of the effectiveness of PSMFC in Moderate continental climate zone. Seasonal changes in environmental conditions have a significant impact on the generation of energy from the PSMFC in regions with moderate continental climate. With the best electrical parameters the cell is characterized in spring and summer. They are significantly lower in autumn and winter. The effectiveness of PSMFC, both as a treatment facility and as electricity generation is directly related to the vegetation period of the planted vegetation and the effectiveness of the photosynthesis, which are a function of the intensity of the light, the duration of the sunshine and the average daily temperatures.
