Engineerings Design Of Processing Volatile Organic Compounds By Trickling Biofilter

The chemical industry is an important pillar industry of national economy. Chemical companies in the production process usually emit complex toxic, harmful volatile organic compounds (VOCs), organic waste gases has faster diffusion speed and features low odor threshold, the impact on the surrounding atmospheric environment is very large, is extremely easily caused around the living environment quality deteriorated. And organic waste gases can attend photochemical reactions and accelerated damage the ozone layer.Organic waste gases has carcinogenic teratogenic role, threatening human health seriously. So the management of organic waste gases has become one of a very pressing task in the the environmental protection workThis pater is a waste gas deepening regulation design for Zhejiang a chemical Co., LTD.The chemical plant waste gases mainly have organic waste gases include toluene,ethyl acetate,methanol and acid gases include phosphorus oxychloride,hydrogen chloride,chlorine. According to the waste gas's characteristics, in this article the pretreatment use water-washing and Low Temperature Plasma,by Trickling biofiler processing toluene,ethyl acetate,methanol ethanol. DMF volatile organic waste gas, etc. Research shows that:the order of removal capacity of single VOCs by biological method is alcohols, aldehydes and ketones and oxygen> BTEX monocylic aromatics hydrocarbons such as> halogenated hydrocarbon. For a single component monocylic aromatics remove the order of ability is:toluene> xylene ethylbenzene benzene or chlorobenzene or two chlorobenzene.Engineering practice shows the basic system is expected to reach the design result, achieved good economic and social benefits.
