Removal of Formaldehyde Using Non-Thermal Plasmas Technology

MIAO Jin-song, XU Hong-li, OUYANG Ji-ting (School of Science, Beijing Institute of Technology, Beijing 100081, China)  
Experimental results are presented for removal of formaldehyde using non-thermal plasmas technology. DBD and corona discharge reactors are designed in the research. The high frequency AC high voltage and DC-AC high voltage are applied on the two kinds of reactors respectively, and the removal effects of formaldehyde are compared under different working parameters. The results show that DBD is more feasible than corona discharge for the removal of formaldehyde with a removal rate of more than 99% under low concentration (10-5) and more than 90% under high concentration (≈2×10-4). This indicates that the formaldehyde can be removed to under national standard by DBD if the formaldehyde concentration is not 100 times more than national standard for formaldehyde.
