Ultraviolet sterilizer use conditions and maintenance and maintenance methods


Optimal conditions for use of ultraviolet sterilizers (1) Water temperature: 5°C-50°C; Ambient temperature: -5°C-50°C; Ambient relative humidity: not more than 93% (at a temperature of 25°C) (2) Voltage: AC 220V±10V, 50Hz. (3) Drinking water: the transmittance (T254) of 1cm of the water entering the treatment equipment: 95%-100%; when the raw water quality is lower than the national drinking water standard (such as: chromaticity higher than 15 degrees, turbidity higher than 5 degrees , the iron content is higher than 0.3 mg/L), first use other purification and filtration methods to make the purification up to the standard, and then purify it with UV-C water quality treatment equipment. (4) Breeding water: fresh water and sea water filtered through sand filtration or other treatments.

(5) Sewage: According to the sterilization requirements, the transmittance (T254) of 1 cm of the water entering the treatment equipment: ≥ 40%; other requirements meet the secondary standards in the national "Comprehensive Wastewater Discharge Standard" GB8978-1996. (6) If the water that needs to be treated cannot meet the above requirements, it should go through appropriate pre-treatment, such as flocculation, sedimentation, filtration, etc., to remove various impurities in the water. Maintenance and maintenance of ultraviolet sterilizer (1) Periodic inspection of ultraviolet sterilizer to ensure the normal operation of ultraviolet lamp.

(2) After the ultraviolet sterilizer has been used continuously for 9000 hours or one year, the ultraviolet lamp should be replaced to ensure a high sterilization rate. Please pay special attention that the ultraviolet light should be kept on, because repeated opening and closing will seriously affect the service life of the lamp. (3) When replacing the ultraviolet lamp, first unplug the lamp power socket and take out the ultraviolet lamp.

When replacing the new lamp tube, be careful not to touch the quartz glass of the new lamp tube with your fingers, because the stain will affect the sterilization light, and carefully put the lamp tube into the stainless steel sterilizer (4) if there is hardness in the water (calcium or magnesium) substances, iron or manganese, then the quartz tube needs to be cleaned periodically. After cleaning the quartz tube, wear special plastic gloves and carefully install the quartz tube into the reactor. After installing the sealing ring, check whether there is any water leakage, plug in the power supply, and ensure that the detection light glows stably.
