Asphalt flue gas emissions come from a wide range of sources, including: (1) industrial thermal processing processes such as coking and refining that produce asphalt; (2) The process of heating asphalt to produce asphalt products; (3) The process of heating asphalt for laying roads, repairing houses, or as anti-corrosion coating; [Details]

The food processing profession generates a lot of organic industrial waste gases containing odors such as hydrogen sulfide, esters, ethers, aldehydes, etc. during the production and processing process, accompanied by a foul odor. Food additives are compounds and natural substances added to food to improve its color, aroma, taste, and other qualities, as well as to meet the needs of preservation and processing techniques. [Details]

In the sludge stacking and compression workshop, foul odors are generated, mainly composed of gases such as hydrogen sulfide, ammonia, alcohols, and hydrocarbons, which are extremely complex; If directly discharged, it will affect the physical and mental health of surrounding residents. [Details]

The generation of garbage odor is due to the fact that household waste contains a large amount of organic matter such as leftovers, vegetable roots, leaves, skin, hair, fat, and leftover materials of poultry, animals, and fish, as well as a certain amount of water. During the accumulation process, due to poor ventilation and the action of microorganisms, a certain amount of ammonia, hydrogen sulfide, organic amines, methane and other odor gases are produced, which are commonly referred to as garbage odor. [Details]

The main sources of sewage odor come from the grid room of sewage pretreatment and anaerobic organisms, the latter of which has a large amount of odor exhaust gas and a pungent odor. [Details]

The organic solvent based ink used in the production process of the printing industry contains 50% -60% volatile components. Printing usually requires adjusting the viscosity of the ink, which increases the emission of organic waste gas. [Details]

Rubber exhaust gas and rubber vulcanization smoke pose significant hazards. The components of the exhaust gas contain odorous substances, which drift far away with the wind direction and stay in the air for a long time. Causing various adverse effects. [Details]

Pharmaceutical companies use organic solvents with low melting points and good volatility in their production processes. Such solvents are likely to evaporate during the production process and cause pollution, with their emissions mainly occurring in operational units such as feeding, reaction, solvent recovery, filtration, centrifugation, drying, and discharge. [Details]

Chemical waste gas comes from toxic and harmful gases emitted from chemical plants during chemical production. The composition of chemical waste gas generated by different chemical production industries varies greatly, with many types of pollutants, complex physical and chemical properties, and varying degrees of toxicity, seriously polluting the environment and affecting human health.
