Description

technical field

The utility model relates to an integrated portable water disinfection device.

Background technique

Ozone has strong oxidizing properties, and ozone can undergo redox reactions in water to generate hydroxyl radicals, superoxide anion radicals and hydrogenated ozone radicals with high reactivity. Therefore, ozone has an excellent bactericidal effect in water and can kill most microorganisms such as bacteria, fungi and their spores, viruses and protists. In view of this, in the field of disinfection, ozone is widely used.
