However, most of the current research on SMX degradation focuses on the anaerobic oxidation and conversion of biological anodes. In this process, various electron donors such as acetate and lactate are required. Microorganisms need to use external energy to play their role. , therefore, it is necessary to find a more energy-saving method for degrading SMX

Description
technical field [0001] The invention relates to the technical field of bioelectrochemistry, in particular to a photoelectric catalysis method for degrading sulfamethoxazole by the synergistic action of microorganisms. Background technique [0002] Sulfamethoxazole (SMX) is one of the most frequently detected drugs in aquatic ecosystems. It is a broad-spectrum bacteriostatic sulfonamide antibiotic, which is widely used in various industries. Synthesis results in stunted growth and reproduction of microorganisms. Since the accumulation and persistence of sulfamethoxazole in the environment can have detrimental effects on aquatic organisms and human health, it is crucial to explore methods to effectively remove sulfamethoxazole from wastewater. [0003] At present, the treatment technology for sulfamethoxazole wastewater mainly includes three aspects: physical adsorption removal, chemical advanced oxidation removal and biodegradation removal. Among them, biological treatment ...
