Water pollution has been the attention of everyone! China’s Ministry of Environmental Protection continues to strengthen the control of water pollution, the main indicators are COD, ammonia nitrogen, total nitrogen, total phosphorus, heavy metals, biological toxicity, E. coli and so on. Among them, the detection of total nitrogen in water is something that relevant departments firmly want to do! The total nitrogen online analyzer is installed at the sewage outlet of a large enterprise, and the data is uploaded to the Environmental Protection Bureau to achieve real-time monitoring. So why do this? Because once the index of total nitrogen in water is excessive, it will bring certain harm (whether it is the environment or human health).

The main components of total nitrogen are ammonia nitrogen, organic nitrogen, nitrate nitrogen, etc., of which nitrate nitrogen is relatively stable in nature and easily soluble in water, so once the diffusion of pollution is very serious. Ammonia nitrogen comes mainly from ammonia water and inorganic substances such as ammonium chloride. Organic nitrogen mainly comes from nitrogen-containing groups in some organic substances, such as organic amines. A large amount of untreated or improperly treated nitrogen-containing wastewater will cause serious harm to the environment. It is toxic to human body, animals and plants. Ammonia in water bodies can be converted into nitrites and nitrates, which enter the body and increase the risk of cancer. Second, it consumes oxygen in the water. The proliferation of algae consumes a large amount of dissolved oxygen in water, which makes the dissolved oxygen content in water drop sharply. Resulting in water eutrophication, so that a large number of organisms in the water body die, resulting in the collapse of the ecosystem.

Therefore, the control of total nitrogen is imperative, and the attitude of the relevant departments in our country is also very resolute! All in all, the total nitrogen index control is necessary, and the enterprise’s own detection of total nitrogen index is also essential! Of course, not only total nitrogen, biological toxicity, Escherichia coli, COD, heavy metals and other indicators are also to be monitored, according to different needs, water quality monitoring. The water quality monitoring equipment used for different parameters is also different.
