At present, air pollution is the most serious of the environmental pollution problems in our country, such as haze and PM2.5 problems always bother people's lives. VOC waste gas is one of the main pollutants in the air pollution. VOC is volatile organic compound (volatileoorganiccompounds) of English abbreviations. The common sense of VOC is the command of organic matter; But the definition in the environmental sense refers to the active class of volatile organic compounds, that is, the class of volatile organic compounds that will cause harm.

Organic waste gas is mainly from various industries (printing waste gas/rubber waste gas/spray paint waste gas/plastic extruder waste) emitted chemical waste gas, fluorine containing benzene waste gas, gaseous hydrocarbons, odor gas, is a part of gaseous pollutants. It is characterized by inflammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, difficult to deal with. In the past decade or so, with the rapid development of economy, industrial enterprises have exploded and become more and more greedy for profits. The lack of investment in environmental protection on the production line has led to the emission of a large number of industrial organic waste gas pollutants, which has caused a sudden decline in atmospheric environmental quality and seriously harmed human health, but also caused huge losses to the national economy. This serious situation has been taken seriously by the government, and the environmental protection department has listed the treatment of industrial organic waste gas as one of the key assessment indicators.
