废气主要成分会根据种类与工艺有所区别，但是大部分都是一些大分子化合物，而且一般相对比较稳定，或者就是一些特别易发生化学法应的小分子化合物，有两级趋势，同时，产生的废气一般含量都比较高，它的这些特性就决定了：它不能使用一些低浓度处理工艺或一些氧化分解类的工艺都比较困难。
The rapid development of the food additive industry brings environmental and health impacts to the surrounding environment and workers in the production and processing line. Therefore, the exhaust gas discharged from the food additive industry needs to be disposed of.
The main components of exhaust gas will be different according to the type and process, but most of them are some macromolecular compounds, and generally relatively stable, or some particularly prone to chemical methods of small molecule compounds, there are two trends, the same time, produce The exhaust gas content is generally high, its characteristics determine: it can not use some of the low-concentration treatment process or some of the oxidative decomposition process are more difficult.
