If the water body itself is healthy, then it can survive well for all kinds of animals, plants and microorganisms. The life of these organisms can drive the material cycle of water and form self-purification ability. Then, the microorganisms in water play a very important role in promoting the material cycle and pollutant degradation in the aquatic ecosystem! Disinfectants are used to treat pollutants in sewage and wastewater. So, do these disinfectants have any impact on the water ecological environment?
If a large amount of disinfectants enter water bodies, it will be harmful to the growth, development and reproduction of aquatic organisms, and will also damage the aquatic ecosystem environment. This will reduce the self-purification capacity of water bodies. Commonly used chlorine disinfectants and chlorophenol disinfectants are highly hazardous. So let’s simply understand some of the impacts brought by chlorine disinfectants!
Whenever disinfection is carried out with chlorine, after the chlorine disinfectant enters the water environment, it hydrolyzes to produce hypochlorous acid, which then reacts with various organic substances in the water to gene rate a series of chlorinated organic compounds. In addition, many natural water bodies contain iodide ions and bromide ions, which can also be oxidized by hypochlorous acid to hypobromous acid and hypoiodic acid, and then generate brominated and iodinated organic substances. These halogenated organic compounds are collectively referred to as disinfection by-products in the field of water treatment. In fact, many studies have shown that various disinfectants have definite cytotoxicity and genotoxicity, and in severe cases, they can even cause cancer and harm. In addition, these disinfection by-products may also enter the sediment and accumulate in the body mass of organisms. Harmful substances in water can be passed on through the food chain or usage, thereby affecting human health!
That’s all for now! What the staff should pay attention to is to do a good job in water quality monitoring. They should monitor the content of chlorine disinfectant added in real time through the RCl900 Total Residual Chlorine Online Analyzer to ensure that it is within a safe range.
