摘　　要：论述了热脱附尾气处理技术的研究现状及未来可能的发展方向。热脱附尾气产业化应用的处理技术有冷凝法、吸附法、热力燃烧法和催化燃烧法等。冷凝法去除率较低,主要作为净化热脱附尾气中高浓度有机污染物的前处理方法;吸附法和热力燃烧法对热脱附尾气中的污染物去除率高,但成本较高;催化燃烧法一般用于净化低浓度尾气。为开发符合我国社会经济水平的热脱附设备,提出热脱附尾气的新型处理技术——水泥窑共处置技术和低温等离子体技术。水泥窑共处置技术基于热力燃烧法去除有机污染物的原理,适用于水泥厂周边的污染场地热脱附尾气的处理;低温等离子体技术具有处理效率高、成本低、不产生二次污染等优势,具有较好的应用前景。The current research status and progress of thermal desorption offgas treatment technologies were reviewed. Four treatment technologies including condensation, adsorption, thermal combustion and catalytic combustion are used in engineering. Condensation is mainly used as a pretreatment of high concentration of organic pollutants in exhaust gas due to its low removal rate. Adsorption and thermal combustion have high removal rate of pollutants in the exhaust gas but with high cost. Catalytic combustion is generally used for purification of low concentration pollutants in exhaust gas. For developing thermal desorption equipment in line with the socioeconomic level of China, two new thermal desorption gas processing technologies including cement kiln co-processing technology and non-thermal plasma technology are proposed. The cement kiln co-processing technology is based on the principle of thermal combustion and can be used for treating thermal desorption offgas of contaminated sites around the cement plants. Non-thermal plasma technology has promising prospects with the advantages of high efficiency,low cost and no secondary pollution.
