| Abstract: | A flat plate reactor using dielectric barrier discharge technology was designed,which produces non-thermal plasma under atmospheric pressure.Influence of applied voltage,gas flow,initial formaldehyde concentration and different forms of devices on removal rate of formaldehyde was studied.The results showed that when electrode distance was 1.6?cm,applied voltage was 20kV,gas flow was 667?mL/min,initial formaldehyde concentration was 50.0?mg/m~3 and ceramic catalyst coating TiO_2 photocatalytic membrane was added,the removal rate of formaldehyde reached over 90%. |
