The use of portable residual chlorine detector in the tap water industry In the water outlet stage of tap water and sewage treatment plants, chlorine disinfection process is widely used to kill bacteria and viruses in water. In the treatment of industrial circulating cooling water, the chlorination and algae removal process is also used, because the cooling water is easy to form slime and dirt during the circulation process, and excessive slime and dirt will cause pipe blockage and corrosion. Chlorination generally refers to the introduction of chlorine into water to kill bacteria and other microorganisms, usually bottled chlorine gas is used. In order to maintain the effect of killing bacteria, the amount of residual chlorine in the effluent should always be kept at 0.5-1 mg/l, and the residual chlorine at the end of the water supply pipe network should also be kept at 0.05-0.1 mg/l. The water quality detector is a detector suitable for industrial sewage, aquaculture, river monitoring, swimming venues and other fields. It can be used with rapid color detection reagents to measure 'fast, simple, accurate and stable', and has a beautiful appearance , simple operation interface, accurate detection system, help users obtain fine data, can analyze water body conditions more accurately and effectively, prevent breeding risks, and avoid losses in time. Application industry: It is suitable for pure water plants, tap water plants, domestic sewage treatment plants, industrial sewage, aquaculture, river monitoring, swimming pools, water source protection, production monitoring, scientific research experiments, etc. Detection principle: Take a certain amount of water body samples, after treatment, drop the detection reagents according to the reagent instructions according to different detection items, the detection reagents will react with the substances to be tested in the water body, and the reaction liquid will show a specific color. Use the white light LED to irradiate the chromogenic solution, the sensor can get its three-light color value, first detect the three-light color value of the blank solution, and then detect the three-light color value of the tested sample, according to the relationship between wavelength and color, according to the reagent after reaction Color, normalize the three-light color value, according to the absorbance formula A=lg(I0/I1), where I0 is the incident light intensity, I1 is the transmitted light intensity, after obtaining the A value, the instrument uses the built-in standard curve according to its corresponding absorbance ( A) It can accurately calculate the concentration value of the detection item in the water body. Instrument features: Chlorine residual detection index, Android intelligent system is more convenient and fast to operate, built-in operation process, simple operation, no training required, fast detection speed, on-site reading data, portable, small size, light weight, convenient for outdoor detection, appearance Small and beautiful, stable and maintenance-free, with good cost performance Imported cold light source, stable optical performance.
