摘要：
使用溶胶凝胶法自制的V2O5-WO3/TiO2催化剂耦合活性分子、紫外光噁、碳纳米管等手段对二氯苯以及二英的脱除降解进行实验研究．单独使用 V2O5-WO3/TiO2，在本实验的较低反应温度(160,°C)条件下对二氯苯基本没有脱除作用，耦合了紫外光、活性分子之后，脱除效率明显上升，在160,°C时最高可以达到99%,．同样的催化剂及噁噁反应器与二英发生源连接用于催化耦合降解二英，发现脱除率为36.25%,，降解效果较差，为2.05%,．同样使用溶胶凝胶法制备的V2O5/TiO2-CNTs复合催化剂在220,°C噁噁时降解二英，发现有二英生成的现象．%The V2O5-WO3/TiO2catalyst,which was prepared by sol-gel method,was utilized to remove 1,2-dichlorobenze(1,2-DCBz)and dioxin,assisted by ozone,UV light and carbon nanotubes(CNTs). 1,2-DCBz was hardly degraded at 160,°C when the V2O5-WO3/TiO2 catalyst was used alone,but when UV and ozone were added, the removal efficiency was increased obviously,which could be as high as 99%,.The same catalyst and reactor were then connected to the dioxin generator to degrade dioxin directly. The removal efficiency value of dioxin was 36.25%,,and the degradation efficiencywas 2.05%,.To improve the degradation efficiency value,a new catalyst V2O5/TiO2-CNTs was composed.It was found that the dioxin was not degraded;on the contrary,it was generated.
