Waste gas emissions affect air quality and health, and attention should be paid to control. Nitrogen oxides are the main pollutants and can be removed by SCR technology. Waste gas treatment can improve air quality, protect biodiversity, and promote the coordinated development of economy, society and the environment.

With the acceleration of industrialization, the problem of waste gas emissions is becoming increasingly serious, waste gas not only pollutes the air we rely on for survival, but also has a profound impact on human health and ecosystems, therefore, waste gas treatment is particularly important.

Nitrogen oxides (NOx) are a class of important atmospheric pollutants, mainly composed of nitric oxide (NO) and nitrogen dioxide (NO₂), which not only pose a threat to human health, but also have a serious impact on the environment.

Waste gas contains a variety of harmful substances, such as nitrogen oxides, particulate matter, sulfur dioxide, etc. Long-term exposure to pollutants will increase health risks such as respiratory diseases and cardiovascular diseases. Acidic substances in exhaust gases cause acid rain, which damages forests, lakes and buildings, and greenhouse gas emissions contribute to global warming and extreme weather events.

Nitrogen oxides are byproducts of fossil fuel combustion and are widely present in industrial production, transportation and natural phenomena. NOx emissions have negative impacts on air quality, human health and ecosystems.

In order to control NOx in the exhaust gas of diesel engine, selective catalytic reduction SCR was adopted. In ₃, NH₃ or urea was used as a reducing substance. Under a certain temperature and catalyst, NH₃ was used to reduce NOx into N₂ and H₂O.

Through waste gas treatment, you can reduce air pollutants, improve air quality, provide people with a healthier living environment, reduce emissions help protect plants and wildlife from pollution, maintain biodiversity, waste gas treatment helps to achieve the coordinated development of economy, society and the environment, and make a force for a livable earth.

Waste gas treatment is not only a response to the current environmental problems, but also a long-term plan for future sustainable development, through the joint efforts of the community, can effectively reduce emissions, protect our common home.
