Abstract Due to the high energy density and large volume of the non-thermal plasma generated by the dielectric barrier discharge(DBD), it can non-selectively degrade the macromolecular pollutants in wastewater under mild reaction conditions, and the entire reaction is efficient and thorough. Therefore, it is widely used in laboratory research of difficult-to-degrade substances in wastewater from printing and dyeing, pharmaceutical, chemical, agricultural and other industries. The characteristics of DBD and the process and mechanism of non-thermal plasma treatment of pollutants in wastewater were reviewed. The key factors affecting the degradation effect of pollutants were summarized and analyzed. The unsolved technical difficulties and the future development direction of non-thermal plasma were pointed out, in order to play a reference role in the deep optimization of the technology.
