预分区与常规分区的结合 处理过程可以有效去除有机物， 尤其是三卤甲烷的形成潜力 生成溴酸盐的风险较低。预分区 已应用于一些供水设施。然而，研究 关于预分区，尤其是预分区的组合 臭氧和生物活性炭 这是最低限度的。目前尚不清楚这两种方法的结合是如何实现的 与臭氧有关的过程可以优化。少校 这项研究的结论可以帮助水务管理者 选择操作参数和合适的处理方法 在控制污染的同时去除有机物的过程 溴酸盐。许多公用事业公司都面临着遵守法规的问题 使用第2阶段消毒剂/消毒副产品 在不久的将来，这些信息可能会 有助于选择治疗方案。包括18个参考文献、图表。

The combination of preozonation with a conventional treatment process may effectively remove organics, especially trihalomethane formation potential, with a lower risk of bromate formation. Preozonation has been applied at some water utilities. However, studies on preozonation, especially the combination of preozonation and ozone-biological activated carbon have been minimal. It is unclear how the combination of ozone-related processes can be optimized. The major conclusions of this research can help water utility managers choose operation parameters and suitable treatment processes to remove organic matter while controlling bromate. Many utilities are faced with complying with the Stage 2 Disinfectants/Disinfection Byproducts Rule in the near future, and this information may be helpful in choosing among treatment alternatives.
