摘　　要： 等离子体-紫外光催化联合技术是一种先进的有机废气治理技术。它解决了单一等离子体技术产率低、能量利用率低和应用条件高的缺点,在环境治理领域具有广阔的应用前景。阐述了3种不同类型的等离子体-紫外光催化反应器。并且对等离子体和紫外光催化处理VOCs的机理,以及2种技术的协同净化机制进行了分析。该技术对喷涂厂废气的净化效果例证了其在实际应用中的可行性。最后,探讨了这一技术存在的问题,以及展望了未来的发展方向。 The united technology of plasma combined UV catalytic is an advanced technology for the treatment of organic waste gas. The disadvantages of that are low energy efficiency,low yield and multi-restriction when using single plasma. The technology has a broad application prospect in the field of environmental control.In this paper,the existing three kinds of plasma-UV catalysis reactor are considered,and the mechanism of single plasma and photocatalysis and their synergetic purification mechanism for VOCs removal,are analyzed. Also,the removal efficiency of the mixture waste gas from spraying factory proved the feasibility of this technology in practical engineering application. Finally,the problems of this technology are discussed,and the development direction in the future is outlooked.
