With the continuous improvement of living standards, we have higher and higher requirements for water quality. The relevant departments require relevant enterprises to install online water quality monitors for real-time monitoring of their water quality, because the pollution of water quality is becoming more and more serious, affecting the normal drinking of human beings. In this chapter, water quality online monitoring instrument manufacturers will understand the causes and hazards of ammonia nitrogen in water together with you in the future!

What Happened to the Excessive Ammonia Nitrogen in the Water?

· Pathogen contamination

It mainly comes from urban domestic sewage, hospital sewage, garbage and ground runoff. Such pollutants actually enter and live in the body through multiple routes.

· Aerobic organic pollution

These substances directly into the water body, through the biochemical action of microorganisms and decomposition into simple inorganic substances carbon dioxide and water, in the decomposition process need to consume dissolved oxygen in the water, in the hypoxic conditions of pollutants occur decay decomposition, deterioration of water quality, often called these organic matter as aerobic organic matter. The more aerobic organic matter in the water body, the more oxygen consumption, the worse the water quality, indicating that the water pollution is more serious.

· Eutrophication pollution

Eutrophication is a phenomenon of water pollution caused by excessive content of nitrogen, phosphorus and other plant nutrients in surface water with slow flow and long renewal period, which causes the rapid propagation of algae and other plankton due to the acceptance of a large number of nutrients required by organisms. Eutrophication of aquatic ecosystems can occur in two ways through chemical pollutants: one is through the increase of the amount of inorganic nutrients limited to plants under normal circumstances; The other is through the increase of organic matter as a decomposer.

· Acid, alkali, salt pollution

Acid and alkali pollution make the pH of the water body change, destroy its buffering effect, eliminate or inhibit the growth of microorganisms, hinder the self-purification of the water body, and can also corrode Bridges, ships, fishing gear. Acid and base often enter the same water body at the same time, after the neutralization can produce some salts, from the point of view of pH value, acid and alkali pollution due to the neutralization and self-purification, but produce a variety of salts, and become new pollutants in the water body. Because the increase of inorganic salt can increase the osmotic pressure of water, it has a bad effect on the growth of freshwater organisms and plants, and in salinized areas, the salt in surface water and groundwater will further harm the soil quality.

What Harm Does Excessive Ammonia Nitrogen in Water Bring?

· Environmental hazards: Under certain conditions, under oxidation reactions and microbial activities, organic nitrogen may be converted into ammonia nitrogen, which consumes dissolved oxygen in water. In the case of sufficient oxygen, ammonia nitrogen can be further oxidized by nitrifying bacteria to nitrite nitrogen and nitrate nitrogen. If there is high ammonia nitrogen in surface water, it can cause toxicity to aquatic organisms, and the toxic effect is mainly caused by ammonia (NH3) in water. The molecule ammonia is also harmful to fish, which can cause toxemia.

· Harm to the human body: by the action of microorganisms, it can be decomposed into nitrite nitrogen, continue to decompose, and then become nitrate nitrogen, completing the self-purification process of water. When the nitrite nitrogen in the water is too high, drinking this water will combine with proteins to form nitrosamines, which is a strong carcinogen. Therefore, people who drink water with the content of these substances exceeding a certain standard for a long time will cause disease, which is very unfavorable to human health.

In addition, the ammonia nitrogen online monitor produced by Hangzhou Modi can monitor the content of ammonia nitrogen in the water in real time, so as to determine whether the ammonia nitrogen in the water exceeds the standard!
