摘要
橡胶有机废气中含有大量VOCs、恶臭物质、水汽以及含油颗粒,会给大气环境质量及人类健康安全带来严重的负面影响。橡胶有机废气具有浓度不一、成分复杂、有明显异味等特点,这使得对其治理的难度较大。目前,橡胶所产生的有机废气的单一治理方法包括臭氧氧化法、吸附法、生物法、热氧化法,但单一治理方法往往不能完全满足经济高效的处理需求。因此,本文根据橡胶废气的特点提出了治理效果更佳的“除尘-臭氧氧化-碱液吸收”“吸附浓缩-热氧化-冷却脱硫”“低温等离子体/光催化-多相催化氧化”组合治理工艺。
Organic waste gas from rubber comprises a large amount of VOCs,odorous chemicals,water vapor,and oil-bearing particles,all of which have a severe impact on the quality of the atmosphere as well as human health and safety.Organic waste gas from rubber has a wide range of concentrations,a complicated composition,and a distinctive odor,making it challenging to manage.At the moment,the single treatment technique for organic waste gas from rubber primarily consists of ozone oxidation,adsorption,biological methods,and thermal oxidation,but these methods typically fall short of meeting the needs of cost-effective and efficient treatment.Therefore,based on thecharacteristics of waste gas from rubber,this paper proposes that combined treatment process of“dust removal-ozone oxidation-alkali absorption”,“adsorption concentration-thermal oxidation-cooling desulphurization”,“low temperature plasma/photo catalysis-multi-phase catalytic oxidation”,and“low temperature plasma/photo catalysis-multi-phase catalytic oxidation”has a better treatment.
