Method for enhancing anaerobic biodegradation of terephthalic acid through light fermentation and application

According to the method for enhancing anaerobic biodegradation of terephthalic acid through light fermentation and application, a semiconductor material such as graphite phase carbon nitride (g-C3N4) is added into an anaerobic biological treatment system of TA to be coupled with an illumination condition to form a light fermentation system, and the g-C3N4 can be used as a mediator for direct interspecific electron transfer (DITE) of anaerobic organisms such as syntrophic bacteria and methanogens, so that the anaerobic biodegradation of terephthalic acid is enhanced. Meanwhile, as a photocatalyst, anaerobic degradation of TA is catalyzed, the speed increasing effect that TA is degraded to generate methane under the action of anaerobic organisms is finally achieved, the problems that at present, TA anaerobic biodegradation is low in speed and long in period are solved, and the technology is simplified and the investment cost is saved on engineering treatment of petrochemical engineering wastewater. 光发酵强化对苯二甲酸厌氧
