What are the general methods for deodorizing waste gas?

Deodorization of waste gas is a technology to deal with the foul smell produced by industrial waste gas and domestic garbage. Common methods for deodorizing waste gas include:

Absorbent method: waste gas passes through the absorbent, so that organic pollutants react or physically adsorb with the absorbent to achieve the purpose of purifying gas. Common adsorbents include activated carbon, activated alumina, iron oxide, etc.

Activated carbon adsorption method: using the adsorption performance of activated carbon, the organic matter in waste gas is adsorbed to achieve the purpose of purifying gas.

Biological method: the process of degrading organic matter by microorganisms and transforming it into harmless substances, such as biological filters and bioreactors.

Oxidation method: the use of oxidants to oxidize organic matter into harmless substances, such as ozone oxidation method, redox method, etc.

Thermal oxidation method: waste gas is burned at high temperature, so that organic matter is oxidized and decomposed to achieve the purpose of purifying gas.

Combustion method: waste gas is directly burned, so that organic matter is completely burned into water and carbon dioxide to achieve the purpose of purifying gas.

Absorption-oxidation method: waste gas first passes through absorbent and then is oxidized to achieve the purpose of purifying gas.

Condensation method: the waste gas is cooled to make the organic matter in it condense into liquid, thus purifying the gas.

The above are some common methods for deodorizing waste gas. Choosing the appropriate technical scheme according to the specific situation can better purify the waste gas.
