基于熵权和层次分析法的VOCs处理技术综合评价

针对化工行业所使用的VOCs控制技术，综合考虑了环境、经济、管理以及技术4个一级因素以及13个二级因素对化工企业中常用的VOCs控制技术进行综合评价，建立基于熵权法与层次分析法相结合的模糊综合评价模型，对9种VOCs末端治理技术进行量化分析评价.阐述了备选VOCs的排放控制技术筛选方法、指标体系的构建以及评价方法，最后以山东省青岛市化工企业为例，给出了模型的求解过程和评价结果.结果显示，催化燃烧技术在环境和经济方面优势明显，热力焚烧技术在经济方面优势显著，吸附技术在技术方面优势突出.综合考虑环境、经济、管理和技术四个方面，VOCs排放控制技术综合评价结果为：催化燃烧>热力焚烧>光催化≈吸附浓缩-燃烧>等离子体>膜分离>吸附>冷凝>生物降解>吸收.

Comprehensive evaluation of VOCs processing technology based on entropy weight method and analytic hierarchy process

Aiming at the VOCs control technology used in chemical industry, the 4primary factors of environment, economy, management, and technology and 13 secondary factors were comprehensively considered to evaluate VOCs control technologies commonly used in chemical enterprises. A fuzzy comprehensive evaluation model based on entropy weight method and analytic hierarchy process was established for quantitatively analyze, and 9kinds of VOCs elimination technologies were evaluated. The selection method of VOCs control technologies, and the construction and evaluation method of index system were described. Finally, taking the chemical enterprises in Qingdao, Shandong Province as an example, the resolution process and evaluation results of the model were given. The results showed that catalytic combustion technology had significant environmental and economic advantages, while thermal incineration technology performed better in economic aspects. Considering the 4aspects of environment, economy, management and technology, the comprehensive evaluation results of VOCs emission control technology were as follows: catalytic combustion > thermal incineration > photocatalysis ≈ adsorption condense combustion > plasma > membrane separation > adsorption > condensation > biodegradation > absorption.
