工业源VOCs污染治理问题及对策

Pollution control problems and countermeasures of industrial source VOCs

近几年,我国大气复合型污染问题十分的严重,PM2.5浓度依旧非常高,O3污染问题还在继续恶化,VOCs是PM2.5与O3生成的主要前体物,对于大气环境有着直接的影响。相关调查数据显示,我国2015年VOCs的排放总量约达到了2500万吨,当中仅工业源排放量就占到了43%,按这个百分比计算,VOCs的排放量超过了1000万吨,而且涉及到的行业非常之多,如石油化工、包装印刷、医药化工、家具制造、橡胶制品制造以及制鞋等等,因此,无组织排问题严重,且浓度高低差异明显,给VOCs的治理工作造成了极大的因难。

In recent years,the problem of atmospheric complex pollution in China is very serious. The concentration of PM2.5 is still very high, and the problem of O3 pollution continues to deteriorate. VOCs are the main precursors of PM2.5 and O3 formation, for the atmospheric environment. Has a direct impact. According to relevant survey data, China’s total emissions of VOCs in 2015 reached about 25 million tons, of which only industrial sources accounted for 43% of emissions. According to this percentage,VOCs emissions exceeded 10 million tons, and related to There are so many industries, such as petrochemicals, packaging and printing, pharmaceutical and chemical engineering, furniture manufacturing, rubber products manufacturing, and shoemaking. Therefore, serious problems of unorganized emissions are serious, and the difference in concentration is obvious, which has caused the treatment of VOCs. Great difficulty.
