Formaldehyde waste gas pollution is one of the important subjects in the environmental protection field. The treatment of formaldehyde with nonthermal plasma is described in this paper. The result of the experiment indicates that a dielectric with high dielectric constant is beneficial for removing formaldehyde when the dielectric is polarized to present micro-corona discharge in the electrostatic field. The effect of electrostatic field strength, gas flow rate and initial concentration on the destruction of formaldehyde are researched for the reactor with or without packed materials. The experimental results indicate that high electrostatic field strengths; low gas flow rate and low initial concentrations of formaldehyde are the factors most suitable for removing formaldehyde. The removal efficiency of the reactor with ferroelectric annulated columns was higher than that without annulated columns.
