中文摘要：
为了降解挥发性有机物VOCs、除尘和灭菌消毒，提出了一种等离子体放电催化室内空气净化技术，它集3个功能于一体。利用此技术在放电催化区负载纳米TiO2和无TiO2的情况下甲醛净化试验的结果表明：等离子体放电催化协同作用降解甲醛的效果明显优于等离子体单独作用的效果;正极性放电降解甲醛的效果明显优于负极性放电;纳米TiO2显著降低了放电产生的臭氧浓度。此结论可供优化室内空气净化器的设计参考。
英文摘要：
In order to remove dust, volatile organic compounds （VOCs） and viruses effectively, the study proposes an indoor air cleaning method using plasma with catalyst. An indoor air cleaner is introduced, which consists of plasma discharging section, electrostatic precipitation section and VOCs decomposition reactor. Two kinds of reactors are designed to investigate the decomposition of formaldehyde in the sealed chamber with an Innova 1312 Photoacoustic multi-Gas monitor. The formaldehyde decomposition caused by both the plasma and nanometer sized TiO2 catalyst is preferable to that by the plasma alone. The removal efficiency of formaldehyde by positive discharge is superior to that by negative discharge. At last, the outlet concentration of ozone of the indoor air cleaner is monitored by the model 400E UV absorption ozone analyzer. The experimental results demonstrate that the outlet concentration of ozone is effectively decreased by nanometer sized TiO2.
