[0002] At present, domestic and foreign urban domestic sewage treatment plants generally use low-cost biochemical treatment methods to treat sewage, and finally discharge it after disinfection. Using chlorine to disinfect water is still a widely used method. Chlorination disinfection has good effect and low cost. During the use of chlorination equipment, due to the low precision of the equipment, it is difficult to continuously supply chlorine, and the subsequent maintenance is large, it is difficult to achieve automatic control, and its safety and reliability are low. It has become increasingly difficult to meet the design requirements of modern water plant disinfection equipment.

[0003] At present, the existing ultraviolet disinfection pools for sewage treatment generally fix the ultraviolet sterilization lamp inside the sewage, and irradiate the water flow by utilizing the light transmittance of water to achieve the purpose of disinfection. However, since the sewage contains a large number of microorganisms and tiny floating objects, the light transmittance of the sewage is poor, which reduces the utilization rate of light energy and the sterilization effect is not ideal. For this reason, we propose an efficient ultraviolet disinfection pool for sewage treatment. Utility Model Content
