Abstract
The experiment results of double dielectric barrier discharge reactor (DDBD) and pulsed corona discharge reactor (PCD) show that the optimal operating frequency of DDBD is 10kHz, the operating power is 0.5~2.1kW, but the optimal operating frequency of PCD is 1600Hz, operating power is 1~4.8kW. PCD reactor is more suitable for deodorization device because of wider operating power and operating voltage, it’s easy to control electric field intensity in appropriate value, better adapt to the working environment. The activated carbon adsorption device was set at the tail of PCD and applied in sewage pumping station, and better deodorization effect is obtained. Ozone escape is controlled in the prescribed range while filtering granular pollutants to avoid the formation of secondary pollution. Pulsed corona discharge plasma deodorization technology has the advantages of good deodorization effect, controllable ozone escape and flexible operation. With the development of power supply technology, the process cost is gradually reduced, so it has good market application value.
