Volatile organic compounds (VOCs) play an important role in the formation of ground-level ozone and secondary organic aerosol (SOA), and they have been key issues in current air pollution prevention and control in China. Considerable attention has been paid to industrial activities due to their large and relatively complex VOCs emissions. The present research aims to provide a comprehensive review on whole-process control of industrial VOCs, which mainly includes source reduction, collection enhancement and end-pipe treatments. Lower VOCs materials including water-borne ones are the keys to source substitution in industries related to coating and solvent usage, leak detection and repair (LDAR) should be regarded as an efficient means of source reduction in refining, petrochemical and other chemical industries. Several types of VOCs collection methods such as gas-collecting hoods, airtight partitions and others are discussed, and airtight collection at negative pressure yields the best collection efficiency. Current end-pipe treatments like UV oxidation, low-temperature plasma, activated carbon adsorption, combustion, biodegradation, and adsorption-combustion are discussed in detail. Finally, several recommendations are made for future advanced treatment and policy development in industrial VOCs emission control.
挥发性有机化合物（VOCs）在地面臭氧和二次有机气溶胶（SOA）的形成中起着重要作用，它们一直是中国当前大气污染防治的重点问题。由于工业活动排放的 VOCs 数量大且相对复杂，因此受到了相当多的关注。本研究旨在对工业 VOCs 的全过程控制进行全面综述，主要包括源头减排、收集增强和末端处理。低 VOCs 材料，包括水性材料，是涂料和溶剂使用等相关行业进行源头替代的关键，泄漏检测与修复（LDAR）应被视为炼油、石化和其他化工行业源头减排的有效手段。本文讨论了几种类型的 VOCs 收集方法，如集气罩、密封隔板等，其中负压密封收集效率最高。目前，对 UV 氧化、低温等离子体、活性炭吸附、燃烧、生物降解和吸附-燃烧等末端处理方法进行了详细讨论。最后，针对未来工业 VOCs 排放控制的高级处理和政策制定提出了几点建议。
