At present, from the type of water disinfection, there are chlorine, sodium hypochlorite, bleaching powder, chlorine dioxide, trichloroisocyanuric acid, hydrogen peroxide, ozone and other agents and methods, in addition to iodine, high oxidation water, ultraviolet disinfection and other means The
In all disinfectants, although chlorine is the most economical, there are problems such as transportation, storage and use of chlorine, and there is a problem that it is difficult to accurately control the dosing.
Compared with other disinfectants, sodium hypochlorite solution is very advantageous. It is clear and transparent, dissolve in water, completely solve the chlorine, chlorine dioxide, ozone and other gas disinfectants exist in the difficult to dissolve in water and difficult to accurately add the technical difficulties, eliminating the liquid chlorine, chlorine dioxide, Ozone and other agents often have run, vent, leakage, poison and other security risks, disinfection does not produce harmful health and damage to the environment side effects, there is no bleach powder used to bring many precipitates. Because of these characteristics, sodium hypochlorite has been widely used in water, including water, water, industrial circulating water, swimming pool water, hospital sewage and other water disinfection and epidemic prevention. However, due to sodium hypochlorite solution is not easy for a long time, and transport inconvenience, sodium hypochlorite and more electrolytic salt on-site preparation and use.
