Description

technical field [0001] The invention relates to a preparation method of a filter membrane electrode and an external electric field enhanced anti-pollution device utilizing the same. Background technique [0002] With the acceleration of industrialization, the problem of energy shortage is becoming more and more serious, among which the problem of water resource shortage is the most prominent. There are still high concentrations of organic matter in wastewater, which is a potential energy source. At present, microbial fuel cell technology has been widely used in the field of wastewater treatment. It can convert the chemical energy stored in organic matter into electrical energy through direct catalytic oxidation of microorganisms. Compared with traditional wastewater treatment technologies, it has achieved high-quality water and energy recovery. . The main components of microbial fuel cells include cathode, anode and ion exchange membrane. Microorganisms attached to the su...
