摘要
利用大型烃分析仪(GHM)对小型柴油车尾气排气管内的黑色残余物进行了定量和定性分析,讨论了残余物质中所含各种类型有机污染物的数量和组成特征。研究结果表明,柴油机在燃烧过程中存在着不完全燃烧现象,尾气黑色残余物中含有129.17mg/g的有机污染物,它们大多为可造成严重环境污染的高熔点、强毒性的重质极性有机污染物。
The black residues in exhaust pipe of tail gas emitted from mini diesel vehicle were analyzed quantitatively and qualitatively with Geofina Hydrocarbon Meter(GHM).The amount and composition characteristics of various organic pollutants in the residue were discussed.Results show that diesel vehicle had the phenomena of inadequate combustion in the process of diesel vehicle operation.The concentration of organic pollutants was about 129.17mg/g in the black residue.Moreover,a majority of organic pollutants had the characteristics of high molecular weight and high melting point and strong polarity and heavy toxicity.These pollutants may result in environment pollution heavily.
