Water pollution has always been our concern, because it is directly related to our health problems. In this chapter, water quality online monitoring instrument manufacturers will understand the problem of oxygen consumption and radiation pollution to water bodies together with you in the future. The details are as follows:
What are Oxygen Consuming Pollutants?
In domestic sewage, food processing and paper and other industrial wastewater, there are carbohydrates, proteins, fats, lignin and other organic substances. These substances exist in the sewage in a suspended or dissolved state and are decomposed through the biochemical action of microorganisms. Oxygen is consumed during this decomposition process, and babies are referred to as ODs.
This pollutant can reduce dissolved oxygen in the water, which can affect the growth of fish and other aquatic life. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing odors such as hydrogen sulfide, ammonia and mercaptan, which leads to a further deterioration of the water quality. The organic matter in the water becomes very complex, and the oxygen consumption organic matter concentration is commonly used in the oxygen consumption per unit volume of water during the biochemical decomposition process, which is expressed by biochemical oxygen demand (BOD)!
Radioactive Contaminants
Radioactive contamination is caused when radioactive materials enter the water. Radioactive pollutants mainly come from the cooling water discharged from nuclear power plants, radioactive waste thrown into the sea, nuclear explosions falling into the water body of scattered objects, nuclear power ship accident leakage of nuclear fuel; When mining, refining and using radioactive materials, if not handled properly, it can also cause radioactive contamination. Radioactive contamination in water can be attached to the surface of organisms, can also enter the accumulation of organisms, and can also produce internal radiation to people through the food chain. Needless to say, the harm to the human body is there!
Water quality monitoring has always been required by relevant departments, so it is necessary to use water quality online monitor. Hangzhou Modi is a manufacturer of water quality online monitoring equipment, the main products are: COD online analyzer, total nitrogen online analyzer, total phosphorus online analyzer, water heavy metal online analyzer, Escherichia coli online analyzer, biological toxicity online analyzer, total residual chlorine online analyzer.
