In the process of industrial production, because most of the fuels used are energy fuels, a large amount of organic waste gas will be produced in the process of production. If these organic waste gas is directly discharged without processing, it will bring serious harm to human health. The pollution control of industrial organic waste gas in China has experienced a long period, and various treatment technologies and methods have been formed in this process. Due to the diversification and complexity of the composition of organic waste gas, the selection of specific treatment methods has also been emphasized. According to the distribution of national industrial types, appropriate treatment technologies have been adopted, At the same time, industrial producers should also speed up the transformation and upgrading of production technology to improve the efficiency of energy utilization.

1. Harm of industrial organic waste gas pollution

Industrial organic waste gas pollution mainly refers to volatile gases mainly composed of organic compounds (VOCs). In the process of chemical production, the production process of many products will lead to the emission of a large number of organic compounds, and these organic compounds will cause a lot of harm to biology and the environment.

(1) Harm to human health: organic compounds (VOCs) can cause a series of photochemical reactions. Under the condition of sunlight, VOCs can react with NOx and other substances in the air, and the generated ozone can be converted into photochemical smog, which will affect the human respiratory system and eyes and cause discomfort. At the same time, VOCs also have a strong pungent smell. When the concentration of VOCs in the air is too high, the human body will have discomfort symptoms. Some toxic VOCs, such as aromatic hydrocarbons, will be released into the air and cause tumor lesions and other serious diseases. For example, "three benzene" in shoemaking process can cause poisoning death; Toluene, xylene and other toxic gases volatilized from coating solvents are also important sources of pollution endangering people's health.

(2) Harm to plants: photochemical smog, sulfur dioxide, fluoride and other organic compounds in industrial waste gas can also cause very serious harm to plants, which can lead to plant withering, yellow and fallen leaves, and even reduce crop yield. At the same time, it will also affect the photosynthesis of plants.

(3) Harm to the global climate and environment: industrial organic waste gas pollution is the main cause of air pollution, and the pollution of these organic waste gas compounds (VOCs) to the atmospheric environment is global. The destruction of industrial organic waste gas to the environment is mainly manifested in three aspects: 1; ② Organic compounds (VOCs) in industrial waste gas can cause acid rain, affect plant growth, reduce crop yield and corrode buildings; ③ Industrial waste gas will lead to global warming and glacier melting, which will cause serious damage to the ecological environment.

2. Causes of common industrial organic waste gas pollution

The organic waste gas in the industry mainly comes from the petroleum, chemical, pesticide and other industries, which has the characteristics of huge amount of emissions, many kinds of pollutants and serious environmental pollution, mainly including nitrogen-containing gas pollutants, sulfur-containing gas pollutants, carbon oxides and carbon hydrogen organic gas pollutants.

2.1 nitrogenous organic gas pollutants

The main N-containing pollutants in the atmosphere are no and No. No and no are the two most harmful nitrogen oxides in the troposphere. No: mainly from the combustion of fossil fuels, automobile, aircraft and all kinds of power machinery combustion process. The natural sources of no are lightning, forest or grassland fire, oxidation of ammonia in the atmosphere and nitrification of microorganisms in the soil. These nitrogen oxides form complex nitrogen-containing organic pollutants through light, lightning and other reactions. These nitrogen-containing organic pollutants will seriously damage the gas composition in the air and cause huge pollution
