1986年，南加州大都会水区开始进行小试和中试试验，以评估在控制味觉和气味问题及微生物的同时满足减少三卤甲烷（THM）要求的方法。由于GAC价格昂贵，该地区将注意力转向了peroxone（过氧化氢/臭氧）。本文描述了目前正在进行的一个全面的peroxone示范项目。本研究的目的是大规模验证peroxone工艺；确认其在消毒副产物、味道和气味控制以及消毒效率方面的有效性；完善全面设计流程；评估可同化有机碳和消毒副产物在大型过滤器中的生物降解。由于改造现有工厂的困难，将使用过氧化物作为预氧化剂，然后进行常规处理或直接过滤。 可选的脱气步骤将允许研究过滤器气体结合。对示范工厂进行了描述，并给出了数字和项目时间表。

The Metropolitan Water District of Southern California in 1986 began bench-scale and pilot-scale tests to evaluate ways to meet reduce trihalomethanes (THMs) while controlling taste and odor problems and microorganisms. Because GAC proved expensive, the district directed its attention to peroxone (hydrogen peroxide/ozone). This paper describes a full-scale peroxone demonstration project that is now underway. The purposes of the study are to verify the peroxone process at large scale; confirm its effectiveness regarding disinfection byproducts, control of taste and odor, and disinfection efficiency; refine the process for full-scale design; evaluate assimilable organic carbon and disinfection byproducts biodegradation in large-scale filters. Because of the difficulty of retrofitting existing plants, peroxone will be applied as a preoxidant, followed by either conventional treatment or direct filtration. An optional degasification step will allow study of filter gas binding. The demonstration plant is described, with figures, and a project timetable is given.
