What should we pay attention to when using ultraviolet lights in swimming pool
1. The life of Du is about 7000 ~ 8000 hours when the ultraviolet lamp is continuously lighted. When the accumulated time reaches Dao, the output of the lamp will be reduced to 65 ~ 70% of the initial value due to time degradation. In order to improve economic efficiency and maintain good bactericidal property, the lamp must be replaced regularly.
2. When the water quality of the swimming pool is unbalanced, scaling will occur. This scaling exists on the quartz casing, which will cover part of the irradiation area and affect the effect. Therefore, the surface of the quartz sleeve should be inspected regularly. Similarly, if the quartz sleeve is aged, it will also affect the UV penetration.
3. When the pool water is turbid, it will block the penetration of ultraviolet rays, resulting in poor bactericidal effect. Therefore, it is necessary to strengthen the supplement of other chemicals when the visibility of the pool water is poor or there is color.
4. The disinfection and sterilization of ultraviolet ray belongs to instantaneous type, and there is no residue. Therefore, the water flowing through the germicidal lamp is sterile, but it can not resist the re pollution. Compared with ozone, its half-life is zero. Therefore, ultraviolet ray can not be used as a disinfectant for swimming pool or massage pool alone, but must be used with other residual drugs. In the ultraviolet radiation, chlorine, bromine, ozone and other disinfectants will be destroyed, so the use of disinfectants will increase.
