现有文献资料表明，隐孢子虫卵囊被去除的次数更多 在水处理过程中，比需氧孢子形成菌更有效 澄清和过滤。因此，监测自然产生的好氧孢子的清除 可以提供完整水处理中隐孢子虫去除的保守估计 流程，进而可用于建立绩效证明（DOP）信用 LT2ESWTR允许，并为 水厂操作员。 这项研究的结果表明:平均原水水位在300至300之间 两个湖源为3000个孢子/L，四个河流源为80000至400000个孢子/L； 过滤水孢子的中值水平很少超过5个孢子/L，且这些去除水平非常低 不明显依赖于水源水浓度；而且，>4-log孢子去除不能 除非原水水位超过10000孢子/L（例如，河流水源），否则应进行证明。包括12个参考文献、表格、图表。

Available literature data indicate that Cryptosporidium oocysts are removed more efficiently than aerobic spore forming bacteria during water treatment processes involving clarification and filtration. Therefore, monitoring removal of naturally occurring aerobic spores can provide a conservative estimate of the Cryptosporidium removal in full-scale water treatment processes, which in turn can be used to establish the demonstration of performance (DOP) credit allowed by the LT2ESWTR, as well as providing a valuable performance evaluation tool for water plant operators. Results from this study showed that: median raw water levels ranged from 300 to 3,000 spores/L for two lake sources and 80,000 to 400,000 spores/L in four river sources; median filtered water spore levels rarely exceeded 5 spores/L and these levels of removal were not apparently dependent on source water concentration; and, >4-log spore removal could not be demonstrated unless raw water levels exceeded 10,000 spores/L (e.g., river sources).
