The residual chlorine online detector monitors the residual chlorine in the solution

The residual chlorine online detector uses a series of analytical techniques to ensure the stability, reliability and accuracy of the instrument's long-term work. With Chinese menu operation, RS485 communication and other functions. It can be used in drinking water treatment plants, drinking water distribution networks, swimming pools, cooling circulating water, water quality treatment projects, etc. to continuously monitor and control the residual chlorine content in aqueous solutions. The residual chlorine online detector has a large-screen dot-matrix liquid crystal display and Chinese menu operation. Simultaneous display of multiple parameters can be realized: residual chlorine value, hypochlorous acid value, PH value, temperature, output current, etc. are displayed simultaneously, intuitive and easy to read, and there is a prompt for range overrun. The bactericidal principle of chlorine-based disinfectants is to hydrolyze to form free hypochlorous acid monomers (after chlorine is injected into water in the form of simple substance or hypochlorite, it will be hydrolyzed to generate free available chlorine, including chlorine gas, hypochlorous acid and hypochlorite. Forms such as acid salt ions, collectively referred to as residual chlorine), uncharged hypochlorous acid monomers can enter the bacteria through the cell membrane, and oxidize with protein substances and nucleic acids in the bacteria, causing bacterial metabolic disorders and killing bacteria. The higher the concentration of hypochlorite, the stronger the bactericidal ability. According to the research, it is proved that hypochlorous acid and hypochlorite ions mainly exist when the pH is close to neutral. When the residual chlorine dose gradually increased from 0.1 mg/L to 3.0 mg/L, the pH value of the wastewater was controlled at about 7.5, and when the residual chlorine dose reached 1.0 mg/L, the COD and BOD removal rates began to decline; when the toxic dose reached 1.5 mg/L At L, the number and form of protozoa did not change significantly, and the removal rates of COD and BOD dropped to 39% and 69% respectively; The body disintegrated and protozoa died in large numbers. The residual chlorine value in this study is based on the traditional activated sludge method. For sewage treatment plants that require denitrification, it cannot be simply considered that 1.0mg/L residual chlorine in the influent will have an impact on the system. The effect of upper internal reflux (generally control r=200 or more) can be tolerated for the influent residual chlorine of sewage treatment plants with denitrification process not greater than 2mg/L.
