Therefore, sodium hypochlorite is widely used in the disinfection of tail water from sewage treatment plants due to its strong oxidizing power.
The sodium hypochlorite generation system for preparing sodium hypochlorite by electrolyzing salt uses solid salt as a raw material to prepare dilute salt water with the concentration of 2.8-3.2%, and sodium hypochlorite can be conveniently prepared on site by electrolysis. The 2.8-3.2% dilute saline solution is prepared by mixing saturated saline water and clear water in a salt dissolving tank according to a certain proportion, and the preparation of the dilute saline solution not only guarantees whether the sodium hypochlorite generator can normally operate, but also influences the consumption of solid salt.
