	VOCs(挥发性**物)治理在我国环境治理所占份额越来越大。在VOCs治理上，标准再严、收费再多，VOCs治理较终要靠改善生产工艺从前端控制排放或者采用先进治理技术从末端治理来实现。




	VOCs (volatile organic compounds) in the management of environmental 
governance in China's share of more and more. In VOCs governance, standards and 
more stringent, fees and more, VOCs governance ultimately rely on improving the 
production process from the front end of the control or the use of advanced 
treatment technology from the end of governance to achieve.




	
		随着国家不断出台VOCs(挥发性**物)治理政策、标准，目前VOCs已作为大气主要污染物，成为各地治理重点，VOCs治理市场也呈现爆发性增长。
	
	
		As the state has introduced a VOCs (volatile organic compounds) governance 
policies, standards, at present of VOCs have been as the major air pollutants, 
become the focus of local governance, governance VOCs market also show explosive 
growth.
	
	
		目前，**相关管理部门比较强调制定VOCs治理法规、规范，以及VOCs检测，却对治理技术研发和治理队伍建设提及不多。我认为应该重视国内技术研发，避免像我国脱硫脱硝行业一样，相当一部分治理技术被国外企业掌握。尤其是国内刚对重点行业征收VOCs排污费，如果国内技术力量不足，排污企业很可能会把VOCs治理市场迅速向国外开放。
	
	
		At present, the relevant administrative departments of the government 
stressed the development of VOCs governance regulations, norms, as well as VOCs 
testing, but the management of technical research and development and management 
of the construction of the team is not much. I think we should pay attention to 
domestic technology research and development, to avoid the same as China's 
desulfurization and denitrification industry, a considerable part of the control 
technology is mastered by foreign enterprises. In particular, the domestic 
industry has just focused on the VOCs sewage charges, if the lack of domestic 
technical strength, sewage companies are likely to VOCs governance market 
quickly open to foreign.
	
	
		当然，引进、借鉴国外先进技术也是必要的。但我认为，目前国内与国外的VOCs治理技术相比并没有太大差距。国外掌握的VOCs末端治理技术，比如冷凝法、吸收法、吸附法、催化法、生物法等，我国的部分专业技术人员已基本掌握，只是还缺乏真正掌握治理技术和工艺的强大技术队伍和治理企业，更缺乏对新技术的研发。当前，我国还缺乏系统、全面组织实施技术人员培养和技术研发。在市场上表现为好像国外比国内的技术先进，于是国内很多有实力的排污企业总是把眼睛盯着国外。为了治理达标，不惜花重金从国外购置所谓的先进设备。
	
	
		Of course, it is necessary to introduce and learn from foreign advanced 
technology. But I believe that the current domestic and foreign VOCs governance 
technology is not much difference compared. Foreign master of VOCs end of 
treatment technology, such as condensation, absorption, adsorption, catalysis, 
biological method, part of China's professional and technical personnel have a 
basic grasp, but there was a lack of truly master control technology and a 
powerful technical team and corporate governance, lack of spent on new 
technology research and development. At present, our country still lacks the 
system, the overall organization of the implementation of technical personnel 
training and technical research and development. In the market as if foreign 
advanced technology, so many domestic enterprises have the strength of the 
foreign eyes staring at foreign. In order to control standards, are willing to 
spend lots of money to buy advanced equipment from abroad ".
	
	
		去年，国内相关机构曾组织举办两期“挥发性**物污染治理与监测技术”系列培训班，重点开展VOCs监测和治理技术培训，收到很好效果。
	
	
		Last year, the relevant domestic institutions have organized two "volatile 
organic pollution control and monitoring technology" series of training classes, 
focusing on VOCs monitoring and control technology training, received a good 
effect.
	
	
		从培训班上，也反映出我国VOCs治理行业普遍存在的问题。首先，大部分治理队伍技术水平不高，尤其是对治理技术的原理了解较浅，相当一部分治理企业只是“比葫芦画瓢”，对有些VOCs的治理只是从工艺上了解，对究竟为什么采用此种工艺(设计)还研究不够。因此，当遇到新的客户或运行出现问题时，不知道如何应对和解决，更谈不上创新。
	
	
		From the training class, it also reflects the problems of China's VOCs 
governance industry. First, most of the management team technical level is not 
high, especially shallow understanding of the principle of treatment technology, 
a considerable part of the corporate governance just "than dipper gourd 
painting", for some VOCs governance is the process understanding, of exactly why 
the use of this technology (Design) also research is not enough. Therefore, when 
the encounter new customers or running problems, do not know how to deal with 
and solve, let alone innovation.
	
	
		其次，对设计程序不很熟悉，在接到一个项目时，不知从何处下手，往往造成设计漏项。
	
	
		Secondly, the design process is not very familiar with, when receiving a 
project, I do not know where to start, often resulting in leakage of design 
items.
	
	
		更重要的是绝大部分治理企业对VOCs治理的难度认识不足。因为VOCs治理不同于烟气脱硫脱硝，SO2和NOx都只是单一的物质，而VOCs是类概念，有数百种，有时候还经常是多种废气的混合物。当接到一个治理VOCs单子时，必须把废气中所有成分的性质搞清楚，才能决定采取什么样的工艺路线，最后确定采用什么设备以及工艺系统的合理配置。
	
	
		More important is the vast majority of the lack of understanding of the 
difficulty of corporate governance VOCs governance. Because VOCs governance is 
different from flue gas desulfurization and denitrification, SO2 and NOx are 
just a single substance, and VOCs is a concept, there are hundreds of species, 
and sometimes is often a mixture of a variety of exhaust gases. When receiving a 
VOCs list of governance, we must make clear the nature of all the components in 
the waste gas, in order to decide what kind of process route to take, and 
finally determine what equipment and reasonable configuration of the process 
system.
	
	
		可是，国内很多治理企业认为，只要有一套先进设备，就能“包打天下”。这种认识是错误的。
	
	
		However, many domestic corporate governance that, as long as there is a set 
of advanced equipment, will be able to conquer the world". This kind of 
understanding is wrong.
	
	
		各界需明确的是，在VOCs治理上，标准再严、收费再多，VOCs治理较终要靠改善生产工艺从前端控制排放或者采用先进治理技术从末端治理来实现。在法规、标准完善的基础上，应多渠道培养我们自己的专业治理队伍。
	
	
		From all walks of life need to be clear, in the VOCs governance, standards 
and then strict, fees and more, VOCs governance ultimately rely on improving the 
production process from the front end of the control or the use of advanced 
treatment technology from the end of governance to achieve. On the basis of 
regulations and standards, we should train our own professional management 
team.

废气处理UV灯之紫外线波长原理
TT废气处理/（整理）紫外线废气处理灯、污水处理灯（UV灯）实际上是属于一种低压汞灯，和普通日光灯一样，利用低压汞蒸汽被激发后发射紫外线。不同的是日光灯的灯管采用的是普通玻璃，253.7nm及更短的紫外线不能透出来，只能被灯管内壁的荧光粉吸收后激发出可见光。如果改变荧光粉的成分和比例，它就可以发出我们通常所见的不同颜色的光。一般杀菌灯的灯管都采用石英玻璃制作，因为石英玻璃对紫外线各波段都有很高的
废气成份分析（**废气处理及臭异味消除技术）
TT废气处理/（整理）废气处理一般分为**废气(VOC类废气及**化合物)与无机废气的处理，臭气异味的消除。 1、**废气选择**废气的处理方法，总体上应考虑以下因素：**污染物的类型及其浓度、**废气的排气温度和排放流量、颗粒物含量以及需要达到的污染物控制水平。当**废气中含有高浓度的可转化**酸的物质时必须特别小心。他们会对设备造成严重的腐
光催化氧化灯技术
光化学及光催化氧化法是目前研究较多的一项高级氧化技术。所谓光催化反应，就是在光的作用下进行的化学反应。光化学反应需要分子吸收特定波长的电磁辐射，受激产生分子激发态，然后会发生化学反应生成新的物质，或者变成引发热反应的中间化学产物。光化学反应的活化能来源于光子的能量，在太阳能的利用中光电转化以及光化学转化一直是十分活跃的研究领域。光催化氧化技术利用光激发氧化将O2、H2O2等氧化剂与光辐射相结合。
