What is the best way to treat nitrite in water?

It can be removed with reverse osmosis membrane, and now the equipment is not expensive, and water is a very important resource in food processing, so it must be treated well.

Due to the production process of nitrite, we can see that in order to eliminate nitrite, we must start from three aspects: reducing excess nitrogen in the water body and increasing the oxygen content of the water body.

1. Reduce excess nitrogen fertilizer in water bodies.

The growth of phytoplankton in the water body needs to take nitrogen fertilizer, and the protein contained in fish excrement will also decompose nitrogen-containing substances, so to reduce the excess nitrogen in the water body, farmers need to master the principle of fertilization with a small amount of multiple times and reduce sedimentation. At the same time, the amount of nitrogen fertilizer should be minimized in the season when the amount of feed is large.

2. Increase the amount of dissolved oxygen in water.

Try to keep the aquaculture water body sufficient solvent oxygen, especially in the large amount of feed, excavation time tends to age the pond to fill new water in time, if the water source conditions are not good, it must be in the corresponding season according to the pond situation often open the aerator. Grasp the principles of using aerators.

3. Reasonable fertilization.

In the high temperature season, try to avoid the use of ammonium bicarbonate, urea and other inorganic nitrogen fertilizers and organic fertilizers with high oxygen consumption to the water body, it is recommended to use special fertilizers for aquatic products, which not only contain various nutrients required for the growth of beneficial algae in the water body, but also add a large number of bioactive bacteria, which can not only cultivate beneficial algae in a directional manner, but also promote the dynamic balance of bacterial phase and algae phase, so as to effectively reduce the content of ammonia nitrogen and nitrite in the water body. Qunlin denitrifying bacteria - nitrite buster, the treatment of nitrite effect is very good!

Mainly biological effects. Under the action of microorganisms, the amino group removed from the protein will become ammonia, which is fine in an acidic environment, and ammonia will exist directly in a molecular form in an alkaline environment, and the substance is reductive and will be oxidized to nitrous acid.

There are two types of bacteria in nature, one is called nitrifying bacteria and the other is called anaerobic bacteria. Nitrifying bacteria specialize in ammonia as food, and through the ammonia in the water, they break down ammonia into nitrite and nitric acid. Anaerobes, in turn, feed on nitric acid and break it down into nitrogen and nitrite.

In this way, through the relay of the two bacteria, the ammonia in the water is broken down into nitrogen and nitrite.

Nitrite poisoning.

Nitrite food poisoning is also known as enterogenic cyanosis, cyanosis, and black mouth disease.

Nitrite poisoning refers to poisoning caused by eating nitrate or nitrite content of pickled meat products, kimchi and spoiled vegetables, or mistakenly eating industrial sodium nitrite as table salt, and can also be seen in drinking bitter well water containing nitrate or nitrite bitter well water, steamer water, nitrite can oxidize the normal oxygen-carrying low hemohemoglobin in the blood to methemoglobin, thus losing the oxygen-carrying capacity and causing tissue hypoxia.

1.NO3+ (nitrate ions) in water are converted to nitrite ions.

2.Microorganisms in the water excrete large amounts of nitride.

3.Under the action of lightning, oxygen and nitride in the air are synthesized into nitrogen oxygenate, and some of them become nitrite after rain, etc., I hope it will help you.

Here are three ways to remove nitrite from water: Mountain belt drain.

1. Use improved disinfectants, such as chlorine dioxide or ozone. These disinfectants can further oxidize nitrite to low-toxicity nitrate, thereby reducing the nitrite level in the water.

2. Sprinkle microbial preparations such as bacillus, photosynthetic bacteria, and nitrifying bacteria in the water body to decompose nitrite through microorganisms.

3. Use "ADB Nitrate Degrader" to adsorb or degrade nitrite through ion exchange.

1. The method of nitrite salt removal in water is to use chlorine dioxide or ozone disinfectants to further oxidize nitrite to low-toxicity nitrate, reduce the nitrite content in water, and then treat the water with activated carbon to remove halogenated hydrocarbons.

2. The increase of nitrite content in water can easily cause nitrite poisoning, and it can also be due to gastrointestinal disorders, nitrate-reducing bacteria in the gastrointestinal tract multiply in large quantities, and nitrate-rich vegetables are eaten, and nitrate is reduced to nitrite in the body, causing nitrite poisoning.

Reducing the nitrite (nitrite ion, NO2-) content in water can be treated quickly in a few ways:

1.Addition of reducing agent: The reduction of nitrite to nitrogen gas is a common treatment.

For example, sodium thiosulfate (Na2S2O3) can be added as a reducing agent to reduce nitrite to nitrogen. This allows the state to convert nitrite into nitrogen and discharge it out of the water body.

2.Use of biological treatment: Water containing nitrite is introduced into a biological treatment facility, and the nitrite is converted into nitrogen gas or nitrate (an oxidation product of nitrite) by the action of microorganisms, thereby achieving water purification.

3.Addition of nitrification inhibitors: In some cases, nitrite production is caused by nitrifying bacteria. Nitrification inhibitors, such as nitronitrate (NAN3), can be added to inhibit the activity of nitrifying bacteria, thereby reducing nitrite production.

4.Photolysis reaction: Under the irradiation of ultraviolet light, nitrite can undergo photolysis reaction and decompose into nitrogen and water. Ultraviolet light treatment devices can be used to degrade nitrite in water.

5.Improve the water environment: Reducing the content of organic matter and nitrite precursors such as ammonia nitrogen in the water body can reduce the formation of nitrite. Therefore, it is also important to strengthen the environmental management of water bodies to prevent the input and accumulation of pollutants to reduce nitrite content.

The appropriate method for treating nitrite in water needs to be selected on a case-by-case basis. When disposing of the process, it should also comply with relevant environmental regulations and standards to ensure that the treatment process is safe and effective and does not have a negative impact on the environment. If you need to treat a large body of water, it is best to consult a professional environmental protection agency or water treatment expert for more professional guidance.
