The monitoring of total residual chlorine needs to be paid attention to

With the continuous development and progress of society, sewage discharge has become a headache for us! In fact, as long as you take appropriate measures, there is nothing to worry about! Water quality online monitor is one of the projects, and it is also a problem that we must pay attention to! Let's learn the necessity of total residual chlorine monitoring in water together! The total residual chlorine in the integrated sewage discharge standard is the chlorine content in sewage stipulated in my country. Once it exceeds the standard, it will bring us harm! The specific hazards are as follows: 1. Drinking hazards: After the tap water is boiled, the organic decay in the water will produce carcinogens such as chloroform. If the residual chlorine cannot be removed, the coffee, tea, and soup we drink every day, after being heated, will double the amount of carcinogens in the human body. Long-term drinking of chlorinated water may lead to heart disease, coronary atherosclerosis, anemia and other symptoms. If pregnant women drink it for a long time, it may have a certain impact on the growth of the fetal heart and lungs, and may even cause arrhythmia and lung dysfunction in newborns. 2. Harm of washing: Bathing with water containing residual chlorine, 40% of the total amount of chlorine in the bathroom is inhaled through the respiratory tract, and 30% is absorbed by the skin, which is several times the amount of chlorine that enters the human body through drinking. In mild cases, itching occurs , In severe cases, the risk of cancer increases by 30%. Especially when bathing children, chlorine can cause dryness, breakage, and even split ends of the hair, as well as bleaching of the skin, peeling of the skin layer, and even skin allergies. After chlorine is inhaled into the lungs through the respiratory tract, it will damage the respiratory cells and easily lead to asthma and emphysema. 3. Cleaning hazards: How does water containing residual chlorine affect vegetables, fruits, grains, etc.? Chlorine will destroy nutrients such as vitamins in vegetables, fruits, and grains, and seriously affect the absorption of nutrients by the human body. Chlorine combined with natural organic matter in water, especially humus, will produce compounds such as chloroform, which is recognized as a carcinogenic, teratogenic, and mutagenic 'three-cause' harmful substance, which is very harmful to the body. So what should we do to reduce or even avoid the harm? The role of residual chlorine is to ensure continuous sterilization and also to prevent water from being re-polluted. However, if the amount of residual chlorine exceeds the standard, it may aggravate the taste and odor produced by phenol and other organic substances in the water, and may also generate organic chlorinated substances such as chloroform that have 'three causes' effects. Detecting the residual chlorine content and existing state in water is very important for doing a good job in drinking water disinfection and ensuring the safety of water hygiene. The total residual chlorine online analyzer is a fully automatic online monitor controlled by an embedded system. After the water sample and anti-interference agent are automatically injected into the reactor, the characteristic chromogenic agent is automatically added for color reaction, and the absorbance of the reactant is measured; the online analyzer can directly measure the total residual chlorine content in the effluent through the absorbance value. Total residual chlorine refers to the amount of residual chlorine remaining after chlorine oxidants are added to water for a period of time, except for those consumed by microorganisms, organic and inorganic substances in the water, including free residual chlorine and combined residual chlorine. Free residual chlorine refers to chlorine that exists in the form of hypochlorous acid (HClO) or dissolved elemental chlorine (Cl2); combined residual chlorine refers to chlorine that exists in the form of chloramines and organic chloramines. The existence of residual chlorine in the water environment is mainly introduced by artificial chlorination. Chlorination is a water treatment technology that uses the strong oxidation of chlorine to non-selectively kill bacteria, algae and other microorganisms in water. With the large-scale use of chlorine, the toxic and carcinogenic effects of its by-products are increasingly concerned, so it is necessary to analyze and measure the chlorine content. At the same time, in order to achieve precise dosing and economically and effectively exert the disinfection and sterilization effect of chlorine, it is also necessary to monitor the residual chlorine content in water in real time.
