Optimal conditions for use of UV sterilizers


(1) Water temperature: 5°C~50°C; Operating environment 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: 1cm transmittance (T254) of the water entering the treatment equipment: 95%~100%; If the amount is higher than 0.3 mg/L), first use other purification and filtration methods to make the purification reach 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 1cm of the water entering the treatment equipment: ≥40%; other requirements meet the secondary standards in the national "Comprehensive Wastewater Discharge Standard" GB8978-1996. (6) The water to be treated, if the water quality cannot meet the above requirements, should first undergo appropriate pre-treatment, such as flocculation, sedimentation, filtration, etc., to remove various impurities in the water. Maintenance and maintenance of ultraviolet sterilizer (1) Regular inspection to ensure the normal operation of the ultraviolet lamp.

(2) After 9000 hours of continuous use 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. Ultraviolet rays have strong killing power to bacteria, and also have certain damage to the human body. The most vulnerable part of the human body is the cornea of ​​the eye. Therefore, at any time, do not look directly at the lighted tube with your eyes to avoid injury. When it is necessary to see, use ordinary glass (wear glasses) or light-transmitting plastic sheet as a protective mask.

Do not make the mistake of using quartz glass, as ordinary glass is almost completely impermeable to ultraviolet light. Once injured, there is no need to panic, the face is burned, the epidermis will fall off after a few days, and it will heal without treatment. Eye injuries will be red, swollen, teary, and stinging, and it takes about three to four days to heal.
