A bioassay method was developed to measure the average intensity within a UV disinfection reactor. The survival of spores of Bacillus subtilis was determined as a function of UV dose to prepare a standard curve. Spores were added to unknown systems, and the survival rate was used to determine the average intensity. A modification was used for flow-through reactors by which spores were injected as a spike and collected at a known time after injection. A point source summation method for calculating intensity was verified by bioassay measurements in a simple cylinder. This calculation method was also applied to multiple-lamp reactors.
开发了一种生物测定方法来测量紫外线消毒反应器内的平均强度。测定枯草芽孢杆菌孢子的存活率作为紫外线剂量的函数，以制备标准曲线。将孢子添加到未知系统中，并使用存活率来确定平均强度。对连续流反应器采用了一种改进方法，即作为一个尖峰注入孢子，并在注入后的已知时间收集。通过在一个简单圆柱体中的生物测定测量，验证了一种用于计算强度的点源求和方法。这种计算方法也应用于多灯反应器。
