Product Introduction

Nitrogen oxides are common pollutants in the atmosphere, usually referring to the general term for nitric oxide and nitrogen dioxide. As air pollutants, nitrogen oxides (NOx) often refer to NO and NO2, which are classified into natural emissions and anthropogenic emissions. Specifically, natural emissions of NOx mainly come from the differentiation of organic matter in soil and oceans, and belong to the natural nitrogen cycle process. Nitrogen monoxide released into the atmosphere by nature accounts for about 90% of the total. NOx emissions from human activities: Most of them come from the incineration process of fossil fuels, such as cars, airplanes, internal combustion engines, and industrial boilers; It also comes from the process of producing and using nitric acid, such as nitrogen fertilizer plants, organic intermediate plants, non-ferrous and black metal smelting plants, accounting for about 10% of the total.

The harmfulness of nitrogen oxides to the environment

NOx has a significant harmful effect on the environment. It is not only one of the primary substances that contribute to acid rain, but also an important substance that contributes to photochemical smog in the atmosphere and a significant factor in the consumption of O3 (somewhat frightening).

Under high-temperature incineration conditions, NOx primarily exists in the form of NO, with NO accounting for approximately 95% of the initially emitted NOx. However, NO is highly prone to react with oxygen in the atmosphere, generating NO2, so NOx in the atmosphere exists mostly in the form of NO2.

NO and NO2 in the air undergo photochemical reactions and convert into each other to reach equilibrium. When the temperature is high or there are clouds and mist present, NO2 further reacts with water molecules to form the second important acid component in acid rain - nitric acid (HNO3).

When there is a catalyst present and suitable meteorological conditions are added, the rate of NO2 conversion to nitric acid accelerates. Especially when NO2 and SO2 are present together, they can catalyze each other and form nitric acid at a faster rate.

The impact of nitrogen oxides on the human body

Nitrogen oxides are irritating gases, and the toxicity of nitrogen dioxide is 4-5 times that of nitric oxide. Inhalation by the human body can cause discomfort symptoms.

Because nitrogen dioxide is difficult to dissolve in water, it has little irritating effect on the eyes and upper respiratory tract, but it is prone to invade the deep bronchioles and alveoli of the respiratory tract, damaging the collagen fibers of the alveoli and causing emphysema like symptoms.

After entering the bloodstream, nitric oxide binds with hemoglobin to produce methemoglobin, which reduces the oxygen carrying capacity of hemoglobin and causes hypoxia. Long term low concentration of nitrogen oxides can cause emphysema like symptoms, leading to a decrease in respiratory anti infection and accompanied by syndrome.

Methods for manipulating nitrogen oxides

There are currently two types of manipulation for nitrogen oxides:

One type is source control, low NOx incineration technology, which is characterized by manipulating the generation of NOx during the incineration process through various technical means.

Another type is tail control, which refers to flue gas denitrification, reducing the generated NOx to N2 through denitrification equipment and then reducing emissions.

Methods for removing nitrogen oxides:

1. Physical method: Generally, coagulants are added to wastewater, and then a grid or other physical barrier is used to treat some pollutants and remove some organic matter. But this method basically only has a slight effect on ammonia nitrogen with a concentration of thousands, and it is usually difficult to rely solely on this method when it reaches several hundred.

2. Biological method: It is widely used in sewage treatment plants or large-scale wastewater treatment stations, usually relying on various bacterial strains, activated sludge and other biological treatments. After aerobic and anaerobic treatment, a complete treatment process is formed, which can effectively remove soluble and colloidal biodegradable organic matter. However, the initial adjustments of this method will consume a considerable amount of engineering investment funds, and the subsequent processing often requires the protection of skilled personnel, which has high requirements for daily protection and needs to be carefully selected.

3. Chemical method: The oxidation effect of chemical agents is used to differentiate ammonia nitrogen. Under this method, the differentiation efficiency of ammonia nitrogen is fast and the treatment time is fast. Generally, the agents are directly added to the outlet for application without too many complicated operations. For example, using the ammonia nitrogen removal agent from Shandong Huanrui Ecology can degrade ammonia nitrogen in about 5-6 minutes, and the concentration is easy to adjust with strong flexibility. By adding different dosages according to different concentrations, the concentration of ammonia nitrogen can be well controlled.
