Product Description:

Ammonia nitrogen wastewater is a kind of common and difficult to degrade inorganic pollutants. If not treated in time, it will bring great damage to our environment. Therefore, we should take effective measures to remove ammonia nitrogen from sewage. Here are some common ways to quickly remove ammonia.
1. Biological nitrification by microbial species: under aerobic conditions, ammonia nitrogen is oxidized into nitrite nitrogen and nitrate nitrogen by nitrite bacteria and nitrate bacteria.
2. Air stripping method: under alkaline conditions, ammonia nitrogen mainly exists in the form of NH3, so that the wastewater is fully in contact with the air, and the volatile NH3 in the water will be transferred from the liquid phase to the gas.
3. Fold point chloride method: by adding excess chlorine or sodium hypochlorite, the ammonia oxidation of wastewater into N2, this method of ammonia nitrogen removal rate is high, stable treatment effect, and not affected by water temperature, but in the process of treatment, the operation cost is high.
4. Zeolite selective adsorption: using the three-dimensional structure of zeolite to screen the ammonia nitrogen in the water, exchange adsorption, the method is greatly affected by the PH value of the solution.
5. Chemical precipitation method: according to the nature of the pollutants in wastewater, when it is necessary for some kind of chemical raw materials, chemical reactions under the certain process conditions, the pollutants generated in the waste water solubility small sediment or polymers, or generate gaseous product does not dissolve in water, so that the waste water purification, or reach a certain removal rate.
In the actual construction, the microbial species biological nitrification method is simple to use, green environmental protection, no secondary pollution, sewage application experience is rich.
