At present, the four most common sources of waste gas pollution in life are industrial waste gas pollution, traffic tail gas pollution, garbage waste gas pollution, and domestic waste gas pollution. Among them, the impact of industrial waste gas pollution on the environment is very serious, mainly because the speed of industrial development is getting faster and faster, there are more and more production enterprises, and the emission of waste gas is also increasing.

Air pollution in cities is getting worse

Industrial waste gas pollution

In the combustion process of industrial production, the combustion process of fuel (coal, oil, natural gas, etc.) is an important source of pollutants transported to the atmosphere. The main component of coal is carbon, and contains hydrogen, oxygen, nitrogen, sulfur and metal compounds. In addition to generating a large amount of soot when the fuel is burned, substances such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds and soot are also formed during the combustion process. The harmful substances produced by non-ferrous metals in pyrometallurgy are mainly heavy metal dust and SO2, and are also accompanied by extremely toxic substances such as mercury, cadmium, lead, and arsenic. When producing light metal aluminum, the pollutants are mainly fluoride and asphalt fume; when producing magnesium, titanium, zirconium, and hafnium, the pollutants emitted are mainly chlorine and metal chlorides. These substances are very harmful to the air, and they are a source of pollution with a relatively large proportion of air pollution.

Car exhaust pollution

The second is the exhaust gas generated by the automobile engine. With the progress of human society, the popularity of automobiles is also getting higher and higher, and then the exhaust gas generated by the engine is increasing. How is the exhaust gas from the engine generated? Engine exhaust gas is produced by the combustion of fuel and air in the cylinder, and the exhaust gas is directly discharged into the atmosphere. The exhaust gas is large because the fuel combustion is incomplete, and the exhaust gas affects the environment and air quality. Of course, there are all other fuel vehicles, such as ship exhaust gas It will also emit exhaust gas, which is generally the exhaust gas generated by the vehicle.

Waste gas pollution

Then there is the exhaust gas generated by urban garbage. The cleaning of garbage has become an important issue in major cities. Among the tens of millions of tons of garbage every day, many of them cannot be incinerated or corroded, such as plastics, rubber, glass, etc. The number one enemy of mankind. The waste gas generated by waste incineration is also the main source of waste gas pollution, and some spoiled and corrupt wastes also produce waste gas, which not only affects the appearance of the city but also affects the cleanliness of the atmosphere.

Domestic waste gas pollution

The waste smoke and exhaust gas discharged from people's lives are also a source of pollution. For example, coal-burning stoves in rural areas, straw burning, and range hoods in cities will all generate exhaust gas more or less. The exhaust gas discharged from human life is of course also a source of pollution A sort of.
