化工园区VOCs污染综合治理技术研究进展

Research Progress on Comprehensive Treatment Technology of VOCs Pollution in Chemical Industry Parks

挥发性有机物(VOCs)是空气中普遍存在的一种有机污染物,能对人体健康和生态环境造成严重危害。化工园区涉及各种化学品的生产、加工和处理,相较于普通园区,污染物种类更多,VOCs排放量更高,导致其极易出现光化学烟雾、雾霾等大气污染问题。因此,有必要从源头减少化工园区的VOCs产生量并开发经济高效的VOCs综合治理技术,以消减和控制化工园区的VOCs污染。基于此,本文介绍了VOCs的来源,概述了化工园区VOCs污染现状,并总结了近年来其治理技术研究进展,以期为化工园区VOCs的综合治理提供理论依据。

Volatile organic compounds(VOCs)are common organic pollutants in the air,which can cause serious harm to human health and the ecological environment.Chemical parks involve the production,processing and handling of various chemicals,compared with ordinary parks,there are more types of pollutants and higher VOCs emissions,which make it extremely prone to air pollution problems such as photochemical smog and haze.Therefore,it is necessary to reduce the production of VOCs in chemical parks from the source and develop cost-effective VOCs comprehensive treatment technologies to reduce and control VOCs pollution in chemical parks.Based on this,this paper introduces the source of VOCs,summarizes the current situation of VOCs pollution in chemical industry parks,and summarizes the research progress of its control technology in recent years,in order to provide a theoretical basis for the comprehensive control of VOCs in chemical industry parks.
