The present application relates to the technical field of disinfection, in particular to a multi-stage flow adaptive ultraviolet disinfection method and system. The water to be treated is divided into a low-flow stage total area and a high-flow stage total area through the flow parameter and water quality parameter of the water to be treated, so that the disinfection effect can be differentiated according to the flow and water quality, and the water in each area can be ensured to receive appropriate ultraviolet dose, so as to achieve the best disinfection effect. By calculating the attenuation coefficient of ultraviolet intensity, the actual intensity of ultraviolet in the water in the low-flow stage can be accurately determined. According to the first target ultraviolet intensity, the required dose of ultraviolet disinfection can be calculated to ensure that the ultraviolet in the water in the low-flow stage reaches sufficient energy. By calculating the ultraviolet intensity through the attenuation coefficient, the effect of ultraviolet in the fast-flowing water can be more accurately reflected, so that the ultraviolet disinfection system is more adaptable.
