How to treat emissions from factories

The treatment of exhaust gases emitted by factories needs to take into account the nature of the exhaust gases and the amount of emissions, choose appropriate treatment methods, and strictly comply with relevant national laws, regulations and standard requirements. At the same time, the factory should also actively promote energy saving and emission reduction technology, take the closed production and resource utilisation, etc., to reduce the emission of waste gas and its impact on the environment. Here with the Everest blue editor to see how to deal with factory emissions.

Exhaust gases from factories can be treated in the following ways:

1. Combustion treatment: decompose the organic matter in the exhaust gas into carbon dioxide and water through high temperature oxidation, or reduce it to harmless substances through reduction reaction.

2. adsorption treatment: using activated carbon, molecular sieve and other substances to adsorb the organic matter and other harmful substances in the exhaust gas.

3. activated sludge method: the organic matter in the exhaust gas is degraded to harmless substances by microorganisms.

4. photocatalytic oxidation: catalytic oxidation of organics and other harmful substances in the exhaust gas by using photocatalysts, and transforming them into harmless substances.

5. Membrane Separation Technology: Use membrane filtration and other technologies to separate the harmful substances in the exhaust gas to achieve the purpose of purification.

The above methods can be used individually or in combination, and the most suitable treatment method should be selected according to the nature of the exhaust gas and emissions. In addition, for the exhaust gases emitted from large-scale factories, the optimal design of the height and location of the discharge pipeline and the installation of purification equipment can also be considered to reduce the impact of exhaust gases on the environment and human health.

For some special factory emissions, such as those containing large amounts of acidic substances or high concentrations of toxic and hazardous substances, more specialised and efficient treatment methods are required.

A common treatment method is to use the wet method, i.e., the exhaust gas is sprayed with water or other chemicals through sprayers to achieve the purification effect. In addition, there are some special treatment technologies, such as corona purification and plasma purification, which can effectively remove harmful pollutants from the exhaust gas.

Regardless of the treatment method, it is necessary to do a good job of monitoring and emission management of waste gas to ensure that the emission meets the relevant national standards and requirements. At the same time, the factory also needs to actively promote energy saving and emission reduction technologies to reduce the total amount of exhaust gas emissions.
