大气污染治理中挥发性有机物的污染现状及治理措施

The pollution status of volatile organic compounds in air pollution control and control measures

挥发性有机物(VOCs)种类繁多,大多数具有刺激性气味和较强毒性,而且在光照下会和大气中的氮氧化物(NOx)等其他物质发生反应,生成二次有机气溶胶,进而导致光化学烟雾等大气污染,严重破坏大气环境,对人们的身体健康造成严重威胁。因此我们应严格控制大气环境中挥发性有机物的排放,加强对挥发性有机物的综合性管控措施,并应用先进的科学技术开展此类物质的治理工作。本文首先阐述了挥发性有机物的来源和危害,然后分析了我国大气污染治理中挥发性有机物的污染现状,最后提出了大气污染治理中挥发性有机物污染治理措施。

There are many types of volatile organic compounds(VOCs),most of which have pungent odors and strong toxicity,and will react with other substances such as nitrogen oxides(NOx)in the atmosphere under light to form secondary organic aerosols.This in turn leads to atmospheric pollution such as photochemical smog,which severely damages the atmospheric environment and poses a serious threat to people’s health.Therefore,we should strictly control the emission of volatile organic compounds in the atmospheric environment,strengthen comprehensive control measures for volatile organic compounds,and apply advanced science.Technology to carry out the management of such substances.This article fi rst explains the sources and hazards of volatile organic compounds,then analyzes the current situation of volatile organic compounds in air pollution control in my country,and fi nally puts forward the control measures of volatile organic compounds in air pollution control.
