包装印刷行业挥发性有机物控制技术评估与筛选

Evaluation and selection of VOCs treatment technologies in packaging and printing industry

挥发性有机物(Volatile Organic Compounds,VOCs)是造成我国城市大气污染的主要因素之一,包括包装印刷行业活动等在内的工业源是VOCs污染的重要来源。工业源的治理技术众多,如何选择合适的治理技术是面临的主要问题。本文在包装印刷行业VOCs排放特点及现有治理技术的研究基础上,针对包装印刷行业中典型VOCs排放与治理,以层次分析法为模型,构建该行业VOCs控制技术评估体系,对包装印刷行业现有治理技术进行综合评估,筛选出最佳可行控制技术,为包装印刷行业VOCs减排控制提供了技术支持。结果表明,吸附回收、热力焚烧、低温等离子3种技术的优先顺序为:低温等离子>活性炭吸附>燃烧,其中低温等离子技术综合评估权重较高,为最优控制技术。

Volatile organic compounds(VOCs)play an important role in urban air pollution.Activities of industries including the packaging and printing industry are regarded as the major sources.How to select the suitable treating techniques is the major problem for emission control.In this article,based on the VOCs emission characteristics of the packaging and printing industry and the existing treatment technologies,using the analytic hierarchy process(AHP)model,an evaluation system for VOCs selection was established and all the technologies used for treatment were assessed.It showed that the priority selection was in the following order:Low temperature plasma>Activated carbon adsorption technology>Combustion.Low temperature plasma was selected as the best available technology due to its highest weight among those technologies.
