| 摘 要： | 调研长三角典型城市213家重点行业企业398套废气处理系统的基础上，分析了吸附、吸收、冷凝、光解/光催化、低温等离子体、燃烧法和生物处理技术在不同行业的应用情况，同时分析了以上处理技术的不同组合工艺在不同行业的应用情况以及实际的VOCs净化效果。结果表明:吸附是最常用的VOCs处理技术，具有广谱性，应用占比为47.49%，吸附再生与燃烧和冷凝等末端处理技术结合时可以达到90%的净化效率，同时废吸附剂产生量降低90%以上，实现VOCs废气处理的资源化和能源化；吸收、冷凝、光解/光催化、低温等离子体和生物法处理工艺则具有一定的选择性和偏好性。选择合理的组合处理技术，可以发挥不同处理技术的优势，保证处理系统的高效性和稳定性。

| Abstract: | The application of different technologies was analyzed based on 398 sets of exhaust gas treatment systems in 213 key industry enterprises in typical cities of the Yangtze River Delta, including adsorption, absorption, condensation, photolysis/photocatalysis, low temperature plasma, combustion and biological treatment methods. This study analyzed the application of different combinations of the above treatment technologies and the actual purification effect of VOCs in different key industries. Results showed that the adsorption technology with broad spectrum was the most commonly used with the application propotion of 47.49%, and the purification efficiency could be as high as 90% above, when adsorption regeneration combined with end-treatment technologies such as combustion and condensation, and the amount of waste adsorbent was reduced by 90% at least, achieving the resource and energy reuse of VOCs containing waste gas. The treatment process had certain selectivity and preference, such as absorption, condensation, photolysis/photocatalysis, low temperature plasma and biological technology. The reasonable selection of technologies combination could take advantage of different processing technologies to ensure the efficiency and stability. |
