代谢解偶联剂在污水处理领域中的研究进展

Metabolic uncoupler is a group of compounds that can inhibits the coupled phosphorylation in prokaryotes and mitochondria. The presence of uncoupler can break the energy coupling between catabolism and anabolism in the cell. The energy generated by electron transfer in the respiratory chain cannot be used for the phosphorylation of adenosine diphosphate (ADP), which inhibits the synthesis of adenosine triphosphate (ATP) in bacteria. In the field of wastewater treatment, the application of metabolic uncoupler was first studied for sludge reduction. However, in recent years, some studies found that metabolic uncoupler inhibited the secretion of quorum sensing signals and biofouling formation in membrane bioreactor (MBR). This review introduced the study history of metabolic uncoupler, described the mechanism of metabolic uncoupling agents inhibiting ATP synthesis in bacteria, reviewed the research progress of metabolic uncoupling agents in sludge reduction, membrane fouling control and their effects on pollutant removal and activated sludge properties, and pointed out the future research direction of metabolic uncoupler in the field of wastewater treatment.
