2. Natural disinfection method: the method of using natural conditions such as sunlight to kill pathogenic microorganisms and achieve the purpose of disinfection is called natural disinfection method.

Sunlight exposure method, sunlight has certain bactericidal power because of its heat, dryness and ultraviolet rays. The sterilization effect of sunlight is influenced by factors such as region, season and time. The stronger the sunlight, the longer the irradiation time, and the better the sterilization effect. When the ultraviolet rays in the sun pass through the atmosphere, they will be weakened by heat dissipation and absorption, and they cannot all pass through the glass. Therefore, they must be directly exposed to the sun to achieve the sterilization effect.
