Dielectric Barrier Discharge Structure Design for Sewage Treatment

Article Preview

Abstract:

The problem of the urban water shortage and water pollution is becoming problem more and more serious. Therefore, governments around the world pay close attention to the application of sewage treatment technology, especially that with high efficiency, low energy consumption and strong operability. Dielectric barrier discharge (DBD) can produce low temperature plasma under atmospheric pressure, and the application of the technology for sewage treatment research gradually becomes to be one of hot research. In this paper, the dielectric barrier discharge structure is designed, and the plasma produced is used for sewage treatment research. The system adopts coaxial type discharge structure. The research shows that the structure is safe and reliable. And, it has low discharge power and can discharge uniformly. So, the plasma produced by dielectric barrier discharge can be convenient and easy to used in sewage treatment, and the result is effective.
