以挥发性有机污染物（VOCs）代表物质甲苯为去除对象，采用低温等离子体-光催化联合技术对其降解开展研究。比较了催化剂-等离子体反应器及空管（不加催化剂）反应器对甲苯的降解性能异同；通过正交试验考察分析了放电区长度、催化剂填充长度、频率、电压和处理气量五个因素对催化剂-等离子体反应器的甲苯去除效果的影响，确定了甲苯降解的最优工艺条件。>Non-thermal　plasma　coupled　with　photocatalysis　was　employed　to　remove　toluene　which　was　a　representative　pollutant　of　volatile　organic　compounds　(VOCs).　The　similarities　and　differences　of　catalyst-plasma　reactor　and　empty　(without　catalyst)　reactor　on　the　toluene　degradation　performance　were　studied.　Furthermore,　the　effect　of　discharge　zone　length,　catalyst　filling　length,　frequency,　applied　voltage　and　gas　flow　rate　on　the　toluene　degradation　of　catalyst-plasma　reactor　was　investigated.　Based　on　the　experimental　results,　the　optimal　conditions　of　toluene　degradation　were　determined.
