The sodium hypochlorite disinfectant generator is a set of devices that generate the sodium hypochlorite disinfectant after the electrochemical reaction occurs through electrolytic saturated saline [or seawater].
At present, in terms of the types of water disinfection, there are chlorine and sodium hypochlorite, chlorine dioxide, trichloroisocyanuric acid, hydrogen peroxide, ozone and other agents and methods, in addition to iodine, high-value oxidized water, ultraviolet disinfection and other means. Among them, ozone (O3) and special drinking water disinfectants are not suitable for large-scale use due to their high cost. Bleached fen (fine) is inconvenient to store and use, the water quality after disinfection is not high, and the cost is high, and it has been gradually phased out. Liquid chlorine (Cl2), as a by-product of the chlor-alkali industry, has a low cost. It has become a more commonly used water disinfectant for a long time in the past, but it is unstable in the transportation and storage of chlorine gas; The solubility in the same water body is low, the pressure of the chlorine gas cylinder is constantly changing, and there is a problem that the dosing is not accurate enough. In addition, the strength of the gas such as chlorine gas has a toxic effect on the environment. Free chlorine is easily formed with many organic substances such as chloroform, Carbon chloride, dioxin and other carcinogenic chlorinated compounds cause secondary pollution of the environment, so chlorine is becoming less and less in use
Compared with other disinfectants, sodium hypochlorite solution is very advantageous. It is clear and transparent, and mutually soluble in water, it solves the technical difficulties of gas disinfectants such as lv gas, chlorine dioxide, ozone, etc. which are difficult to dissolve in water and cannot be accurately dosed, and solves the problems of liquid lv, chlorine dioxide, etc. Drugs often have hidden dangers such as running, leaking, leaking, poisoning, etc. During disinfection, no side-reactants harmful to health and environmental damage are produced, and there are not many deposits brought about during use. Because of these characteristics, it has good disinfection effect, accurate dosing, stable operation, convenient use, easy storage, harmless to the environment, no secondary pollution, and can be added under any environmental working conditions.
As far as the sodium hypochlorite generator is concerned, the country has issued the GB 12176-1990 national standard on January 12, 1990. It is a product that has been approved, the technology is very mature, the work is very stable, and there is *** data to query. Many practical applications have proven that sodium hypochlorite generator is a device with very low running cost, accurate drug dosing and good disinfection effect. At present, as a practical conventional water treatment equipment, sodium hypochlorite generator has attracted great attention from all sectors of society.
