Abstract

The invention discloses an anode photosynthetic solar fuel cell system additionally provided with degradation strains and application thereof. According to the anode photosynthetic solar fuel cell system, at least one of additionally added degrading bacteria, namely comamonas or bacillus, is added, and the abundance of electrochemical active microorganisms in soil is improved in a manner of externally connecting the degrading strain so that the capability of degrading surrounding environmental pollutants is improved, and the system has a good application prospect in treating Cr and NO3-N pollution in the soil.

Description

technical field [0001] The invention relates to the field of plant-microbial fuel cells, in particular to an anode photosynthetic solar fuel cell system and application thereof. Background technique [0002] Microbial fuel cell is a new type of device that converts chemical energy in organic or inorganic substances directly into electrical energy by using microorganisms as catalysts. The basic principle is: microorganisms in the anode area generate electrons through substrate metabolic activities, and electrons pass from the anode through wires and external resistance. [0003] Electricity generation and pollutant degradation are two basic functions of microbial fuel cells (MFCs), and they are also the most attractive advantages of microbial fuel cells (MFCs) as a new type of environmental governance and energy technology. A large number of studies have shown that: compared with general anaerobic biodegradation technology, microbial fuel cells (MFCs) have a more efficient a...
