	随着近两年法律法规及标准的完善，VOCs（挥发性**物）逐渐进入环保行业和公众视野，这个在PM2.5形成之前的较较重要的前体物———VOCs的万千变化，让细粒子污染渐趋严重，对于VOCs的治理已经成为各地大气污染治理的一大重点。
With nearly two years of legal regulations and standards, VOCs (volatile organic compounds) gradually into the environmental protection industry and public view, this is the most important precursor in the formation of VOCs - PM2.5 of the myriad changes, so that fine particle pollution is becoming serious, the governance of VOCs has become a major focus of air pollution control.
VOCs究竟为何物
What is the VOCs
VOCs是挥发性**化合物（volatile organic compounds）的英文缩写。根据WHO定义，挥发性**化合物（VOC）是指在常温下，沸点50℃—260℃的各种**化合物。VOC按其化学结构，可以进一步分为：烷类、芳烃类、酯类、醛类和其他等。目前已鉴定出的有300多种。
VOCs is an abbreviation for volatile organic compounds (organic compounds volatile). According to the definition of WHO, volatile organic compounds (VOC) are 260 kinds of organic compounds at the boiling point at 50. VOC according to their chemical structure, can be further divided into: alkanes, aromatic hydrocarbons, esters, aldehydes and other etc.. There are more than 300 kinds of. The most common of benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloro ethane, diisocyanate (TDI), two different cyanide toluene ester.
VOCs治理刚刚起步
VOCs governance has just begun
VOCs具有较强的光化学反应活性，能在环境中进行二次转化，其光化学反应会引发城市光化学烟雾，造成二次污染；VOCs作为细颗粒物（PM2.5）的前体物之一，是造成灰霾的重要原因；特别是在夏季，VOCs对城市和区域臭氧的生成也至关重要。
VOCs is strong photochemical reaction activity, the quadratic transformation in the environment and its photochemical reactions will cause of urban photochemical smog, cause secondary pollution; one of VOCs as fine particulate matter (PM2.5) precursor is important reason to cause haze; especially in the summer season, VOCs on urban and regional ozone generation is also crucial.
尽管VOCs危害很大，但是对其治理并未很早提上议程。直到2011年，国家“十二五”规划中强调“深化颗粒物污染防治”，作为大气细颗粒物的重要来源，挥发性**物的控制逐步受到重视。
Despite the great dangers of VOCs, but its governance has not been put on the agenda. Until 2011, the national "Twelfth Five Year Plan" stressed the "deepening of particulate pollution prevention", as an important source of atmospheric fine particulate matter, the control of volatile organic compounds gradually received attention.
2011年12月，《国家环境保护“十二五”规划》发布，其中强调“加强挥发性**污染物和有毒废气控制”，正式提出控制挥发性**污染物的排放，并明确提出开展挥发性**污染物监测工作。
In December 2011, the national environmental protection "12th Five Year Plan" released, which stressed the "strengthening of volatile organic pollutants and toxic waste gas control", formally proposed to control the emissions of volatile organic pollutants, and clearly put forward to carry out the monitoring of volatile organic pollutants.
2013年9月，**印发《大气污染防治行动计划》，进一步明确了需要控制挥发性**污染物的重点行业。同期，环境保护部等六部委共同发布《京津冀及周边地区落实大气污染防治行动计划实施细则》。
September 2013, the State Council issued the air pollution prevention action plan, further defined the need to control the key industries of volatile organic pollutants. Over the same period, the Ministry of environmental protection and other six ministries jointly issued the implementation of the implementation of the air pollution prevention action plan in Beijing, Tianjin and surrounding areas of the implementation details of the implementation of the air pollution prevention and control.
2014年7月，环境保护部等六部委共同发布《大气污染防治行动计划实施情况考核办法（试行）实施细则》，规定了全国大气挥发性**物控制的进度。至此，大气挥发性**物治理工作开始开展，监测工作也正式开启。
July 2014, the Ministry of environmental protection and other six ministries jointly issued the implementation of the air pollution prevention action plan (Trial) implementation details, and provides the progress of atmospheric volatile organic compounds in the country. At this point, the work of the management of volatile organic compounds began to carry out, the monitoring work is also officially open.
VOCs（挥发性**物）治理技术
Treatment technology of VOCs (volatile organic compounds)
“目前应用范围较广的VOCs治理技术主要包括吸附回收技术、吸附浓缩技术、催化燃烧技术和高温焚烧技术等。此外，低温等离子体技术、生物治理技术和组合技术得到了快速发展。但是UV光解**废气作为新型技术，是**废气的克星，能将**废气净化成无毒无害的物质。
"At present, the most widely used VOCs control technology mainly includes the technology of adsorption and recovery, adsorption and concentration technology, catalytic combustion technology and high temperature burning technology. In addition, the low temperature plasma technology, biological treatment technology and combination technology has been rapid development. But the UV photolysis of organic waste gas as a new technology, is the bane of organic waste gas, the organic waste gas purification into harmless substances.
山西TT废气处理环保技术中心推出的高臭氧紫外线灯就是专门为**废气净化服务的，期待与更多的环保企业合作！！
Shanxi TT waste gas treatment technology center launched the high ozone ultraviolet lamp is specifically for the organic waste gas purification services, and look forward to working with more environmental protection enterprises!!
”中国环保产业协会废气治理**副秘书长、**防化研究院研究员栾志强在*环保联合会近日举办的“**期VOCs污染治理与监测技术（系列）培训班”上说。
"Deputy Secretary General of China Association of environmental protection industry waste management committee, the Liberation Army Research Institute of chemical defense researcher Luan Zhiqiang in China Environment Federation recently held the" first phase VOCs Pollution Control and monitoring technology (Series) training class "said.
工业上，VOCs排放涉及的行业众多，污染物种类繁多，组成复杂，其种类有烃类、酮类、酯类、醇类、酚类、醛类、胺类、氰类等。所以治理技术体系复杂，涉及10多种技术及组合技术。
Industry, the emissions of VOCs involving many industries and many kinds of contaminants, complex composition, species with hydrocarbons, ketones, esters, alcohols, phenols, aldehydes, amines, cyanide and other. So the control technology system is complex, involving more than 10 kinds of technology and combination technology.
业内人士认为，总体来说，VOCs治理有两类基本技术，一类是回收技术，治理的基本思路是对排放的VOCs进行吸收、过滤、分离，然后进行提纯等处理，再资源化循环利用。比如吸附回收技术、吸收技术和膜技术等。另一类是销毁技术，处理的基本思路是通过燃烧等化学反应，把排放的VOCs分解化合转化为其他无毒无害的物质。比如燃烧技术、生物技术、等离子体技术和UV光解技术等。目前，这两类技术都得到研究和应用。
Industry believes that, overall, VOCs governance has two basic technologies, one is recycling technology, the basic idea is to control emissions of VOCs absorption, filtration, separation, and then purification and other processing, and then resource recycling. Such as adsorption recovery technology, absorption technology and membrane technology, etc.. The other class is destroyed by the technology, and deal with the basic ideas is through combustion chemical reaction, the emissions of VOCs decomposition combined into other innocuous substances. Such as combustion technology, biotechnology, plasma technology and UV photolysis technology, etc.. At present, these two kinds of technologies have been studied and applied.
