到底什么才是VOCs治理的主流技术

有机废气控制技术可分为源头削减技术、过程控制技术和末端治理技术，以末端治理技术为主。
末端处理技术有：1、吸附法；2、膜分离法；3、液体吸收法；4、催化燃烧法；5、光催化氧化处理技术；6、生物处理技术；
对于VOCs的治理，单一的技术很难达到国家现在的排放标准。针对不同的废弃处理，将不同的技术相结合会达到更好的效果。
比如在去除VOCs之前要进行预处理，除掉废气中的尘等;
在处理大风量、低浓度且没有回收价值的有机废气时，可以选择转轮浓缩吸附+蓄热式催化燃烧联合技术，有回收价值的有机废气可以选择吸附浓缩技术+冷凝回收技术联用;
在处理高浓度有机废气时可以选择冷凝+吸附技术、吸附浓缩+冷凝回收/燃烧技术等;在处理恶臭气体时可选择生物处理+光催化或低温等离子技术;
在处理油气回收时可选择冷凝+膜分离技术等。
合理的联合技术解决了单一处理技术无法处理不同VOCs的难题，也是以后在处理VOCs方面的主流选择。

The printing profession volatile organic compound waste gas government
engineering research volatile organic compound (VOC) is kind of
gaseous state pollutant, the massive industries organic waste gas
disperses into the atmosphere, inevitably causes the atmospheric
environment drop in quality, brings the serious harm for the human
body health, the national economy creates the heavy loss for.
Especially is difficult regarding the low density VOC waste gas
control. In the plastic color printing profession, each kind of
diluent massive uses, produce the industry organic waste gas, creates
to the environment pollution, is question which the current printing
profession environmental protection urgently awaits to be solved. This
article take the Dalian greatly rich plastic color printing limited
company as the research background, the organic waste gas which
produces in the production process carried on the monitor to it,
finally indicated, the organic waste gas principal constituent is the
toluene and the ethyl acetate, the toluene discharges the density and
discharges the speed to have exceeds the allowed figure, has already
caused the certain degree pollution to the environment, therefore, is
urgent needs to carry on the government. The VOC control may from the
many kinds of ways realization, the most economical method be reduces
VOC through the clean production way the use and sends out. But
cleanly produces the road very is also long, the terminal government
technology still was the essential one method. This article introduced
in the project actual center application each kind of organic waste
gas government technology, and carried on the comparison to various
technologies, the synthesis had considered the consumption of
material, the energy consumption, the investment, the processing cost
and so on, in this foundation, the choice activated charcoal textile
fiber adsorption - condensation recycling craft did for this project
organic waste gas processing method. And has completed the government
plan technological design, has carried on the investment and the cost
analysis, uses this method to be able effectively to govern the VOC
waste gas, simultaneously satisfies in the economical the request.
