Abstract
Dielectric barrier discharge (DBD) plasma in advanced oxidation technology can degrade organic pollutants in water under mild conditions. It has the advantages of universality, simple reaction conditions, and no secondary pollution. However, the light, electrons, and low-reactive substances generated during the discharge process cannot be fully utilized, which limits the further application of DBD plasma. Therefore, the DBD system coupled with catalysis can not only solve the above problem, but also transforms the low-active substances into high-active substances and improves the degradation rate of organic pollutants. Based on this fact, this review focuses on the characteristics and principles of DBD plasma coupled with photocatalysis, adsorption, Fenton oxidation, persulfate oxidation and composite technology to treat organic wastewater. This review puts forward some problems of DBD synergetic catalysis technology, and looks forward to the future development direction of this technology to treat organic pollutants in water.
