However, the use of chlorine has been abandoned gradually due to its toxicity. The method for sterilizing tap water by using sodium hypochlorite instead of chlorine is a very commonly used method at present, and hypochlorous acid is formed by adding sodium hypochlorite into water and then hydrolyzing, so that the water body is sterilized. Sodium hypochlorite is used as a chlorine-containing disinfectant, and has good disinfection effect because of safe use, and becomes a suitable substitute for traditional liquid chlorine disinfection. Sodium hypochlorite in the existing water works is generally purchased as a finished product, and is unstable and is inevitably changed in transportation or under other conditions, so that the disinfectant is invalid or the efficiency is reduced.
