大气环境中挥发性有机废气的治理技术

Volatile organic waste gas treatment technology in atmospheric environment

近年来,由于各种挥发性有机气体在大气中扩散,导致空气环境污染越来越严重。挥发性有机气体主要来自于石油、化学物质、运输、涂料、矿业、纺织、金属等产业释放的有机溶剂,是大气污染物中最常见的气体。另外,挥发性有机气体在一定的温度下会产生硫烃、含氧烃、氮烃、卤代烃、烃类以及低沸点的多环芳香烃等有害物质。这些有害物质都会对人类、动物、植物中造成某种损伤,因此进行处理挥发性有机气体的技术研究十分重要。

In recent years, air pollution is becoming more and more serious due to the diffusion of various volatile organic gases in the atmosphere. Volatile organic gases mainly come from the organic solvents released by petroleum, chemical substances,transportation, coating, mining, textile, metal and other industries, and are the most common gases in the air pollutants. In addition,volatile organic gases at a specified boiling point tend to release sulfur hydrocarbons, oxygen hydrocarbons, nitrogen hydrocarbons,halogenated hydrocarbons, hydrocarbons and low boiling polycyclic aromatic hydrocarbons.These harmful substances can cause some damage in human, animal and plant, so it is very important to study the technology of dealing with volatile organic gas.
