初步的中试规模调查表明，单独使用臭氧以及臭氧和过氧化氢的组合（称为peroxone）都可以从南加州大都会水区使用的水源中去除甲基叔丁基醚（MTBE）。在测试条件下，peroxone比单独使用臭氧更有效地去除MTBE。在初步试验中，peroxone（此处为4 mg/L臭氧和1.3 mg/L过氧化氢）从加利福尼亚州水项目和科罗拉多河的水样中平均去除了约78%的MTBE。然而，在环境条件下，在两个水源的经peroxone处理的样品中，溴酸盐的产生浓度高于饮用水中溴酸盐的最大污染物水平10 ug/L。较低的pH值为6。 5将来自两个水源的样品中的溴酸盐生成量减少了约20%，但并未将溴酸盐浓度降低到10 ug/L以下（水源中含有约0.1 mg/L的溴酸盐）。进一步优化peroxone工艺可以最大限度地减少溴酸盐的形成，同时提供可接受的MTBE去除和消毒。包括33个参考文献、表格和图表。

Initial pilot-scale investigations demonstrated that both ozone alone and a combination of ozone and hydrogen peroxide (known as peroxone) can remove methyl tertiary butyl ether (MTBE) from water sources used by the Metropolitan Water District of Southern California. Under the tested conditions, peroxone more effectively removed MTBE than did ozone alone. In pilot tests, peroxone (here, 4 mg/L ozone and 1.3 mg/L hydrogen peroxide) removed an average of about 78 percent of the MTBE from water samples taken from the California State Water Project and the Colorado River. However, in peroxone-treated samples from both water sources at ambient conditions, bromate was produced at concentrations above the maximum contaminant level of 10 ug/L for bromate in drinking water. A lower pH of 6.5 reduced bromate formation by about 20 percent in samples from both water sources, but it did not reduce the bromate concentration below 10 ug/L (the water sources contained about 0.1 mg/L bromide). Further optimization of the peroxone process may minimize bromate formation while providing acceptable MTBE removal and disinfection. Includes 33 references, tables, figures.
