摘要:
低压汞灯电光转化效率受水温影响，因此灯的水温特性对水处理紫外反应器的优化设计和运行维护至关重要。基于自行研制的荧光微探头和国际紫外线协会提出的空气中电光转化效率测试方法，提出低压汞灯电光转化效率水温特性测试方法并搭建测试装置，对4个厂家生产的低压汞灯进行测试。结果表明，所研发的方法可准确测定低压汞灯电光转化效率与水温的关系。当水温从5 ℃升高到35 ℃时，受试灯管电光转化效率整体呈现上升趋势。灯A、B在水和空气中的电光转化效率相近，灯C在水中的电光转化效率高于其在室温下的效率（35.5%），灯D在水和空气中的电光转化效率均最低。将空气中电光转化效率应用于水处理会造成误差，应针对实际应用场景，依据准确测定的低压汞灯水温特性，选择适宜的低压汞灯，提高效率并保障可靠性。
Abstract:
The electro-optical conversion efficiency (ECE) of low-pressure mercury lamp is affected by water temperature. Therefore, the water temperature characteristic of the lamp is very important for the optimal design and operation maintenance of UV reactor for water treatment. Based on the self-developed micro fluorescent silica detector (MFSD) and the ECE test method in air proposed by International Ultraviolet Association, this paper proposed a test method for determining water temperature characteristics of low-pressure mercury lamp ECE, and built a device to test the water temperature characteristics of low-pressure mercury lamps produced by 4 manufacturers. The method accurately determined the relationship between ECE of low-pressure mercury lamp and water temperature. When the water temperature was increased from 5 ℃ to 35 ℃, the ECE of the tested lamp showed an overall increasing trend. The ECEs of lamp A and B measured in water were similar to those measured in air, the ECE of lamp C in water was higher than that at room temperature (35.5%), and the ECEs of lamp D in both water and air were the lowest. The application of the ECE measured in air to water treatment would introduce errors. Therefore, the appropriate low-pressure mercury lamp should be selected based on the water temperature characteristics of low-pressure mercury lamp accurately measured in actual application scenarios, so as to improve the efficiency and ensure the reliability.
