为了最大限度地提高对微小隐孢子虫卵囊的消毒效率，同时最大限度地减少消毒副产物（DBP）的形成，尤其是溴酸盐，优化全尺寸臭氧接触器的操作条件非常重要。优化接触器性能的直接方法是在各种操作条件下测量废水中的溴酸盐浓度和活的微小隐球菌卵囊的密度。不幸的是，尽管溴酸盐分析可以很容易地进行，但由于微小隐孢子虫卵囊在自然界中通常出现的浓度较低，目前尚不可行。最常用的消毒方法是接触时间（CT）和消毒剂浓度。 然而，由于反应器内出现非理想流体动力学，例如返混和短路，这种方法可能具有严重的局限性和不确定性。另一种方法是使用荧光染色微球作为非生物替代物。这种方法背后的主要概念是，一旦将微球引入全尺寸接触器中，将经历与微生物经历的相同的流体动力学非理想性和消毒剂暴露。由于荧光染料与臭氧的反应，微球的荧光强度会降低，这种荧光损失可以与C的失活动力学相关。 帕武姆。本研究的目的是研究荧光染色聚苯乙烯微球作为工具的使用，以优化操作条件，从而最大限度地灭活微小隐球菌，同时减少溴酸盐的生成。本文介绍了台架试验与全尺寸演示试验的初步结果之间的相关性。包括8个参考文献、表格、图表。

The optimization of conditions used to operate full-scale ozone contactors is important in order to maximize disinfection efficiency against Cryptosporidium parvum oocysts while minimizing the formation of disinfection byproducts (DBP), particularly bromate. A direct approach to optimize contactor performance would be to measure both bromate concentrations and densities of viable C. parvum oocysts of the effluent under a variety of operating conditions. Unfortunately, although bromate analysis can be performed easily, the quantification of viable C. parvum oocysts is not currently feasible due to the low concentration at which they usually occur in nature. Instead, the most common approach to assess disinfection efficiency is the CT (product of disinfectant concentration and contact time) approach. Nevertheless, this approach may have severe limitations and uncertainties, due to the occurrence of non-ideal hydrodynamics, e.g. back-mixing and short-circuiting, within the reactor. An alternative approach is the use of fluorescent-dyed microspheres as non-biological surrogates. The main concept behind this approach is the fact that the microsphere, once introduced into a full-scale contactor, would experience the same hydrodynamic non-idealities and exposure to the disinfectant as those experienced by the microorganisms. The fluorescence intensity of the microsphere would decrease as a result of the reaction of the fluorescent dye with ozone, and this loss of fluorescence can then be correlated to the inactivation kinetics of C. parvum. The objective of this study is to investigate the use of fluorescent-dyed polystyrene microspheres as a tool to optimize the operating conditions that would result in maximum inactivation of C. parvum with minimum formation of bromate. The correlation developed between bench-scale experiments and the preliminary results obtained for full-scale demonstration tests are presented in this paper. Includes 8 references, table, figures.
