VOCs即挥发性有机物,是指常温下饱和蒸汽压大于70Pa、常压下沸点在260℃以下的有机化合物,或在20℃条件下蒸汽压大于或者等于10Pa具有相应挥发性的全部有机化合物,主要来源于石油化工、汽车发动机尾气、制药、印刷等行业,其主要成分为烃类、酚类、芳香族类等。VOCs可在大气中形成光学烟雾,对环境和人体造成极大的危害,VOCs通过呼吸道和皮肤进入人体后,对人的呼吸、血液、肝脏等系统和器官造成暂时性或永久性损伤,尤其是苯类和芳香族类等多环芳烃对人体具有致癌作用。因此VOCs的处理越来越受到世界各国的重视.VOCs are volatile organic compounds, which refer to organic compounds with a saturated vapor pressure greater than 70Pa at room temperature and a boiling point below 260°C under normal pressure, or all organic compounds with corresponding volatility at a vapor pressure greater than or equal to 10Pa at 20°C. It comes from petrochemical, automobile engine exhaust, pharmaceutical, printing and other industries, and its main components are hydrocarbons, phenols, aromatics, etc. VOCs can form optical smog in the atmosphere, causing great harm to the environment and the human body. After VOCs enter the human body through the respiratory tract and skin, it will cause temporary or permanent damage to the human respiratory, blood, liver and other systems and organs, especially Polycyclic aromatic hydrocarbons such as benzene and aromatics are carcinogenic to humans. Therefore, the treatment of VOCs has attracted more and more attention from all over the world.
