2002年，南太浩公共事业区（STPUD）购买、允许并安装了加利福尼亚州有史以来第一个高级氧化工艺（AOP）处理系统，利用O₃/H₂O₂处理MTBE污染的地下水，作为其箭头3号井（AH#3）的饮用水。2003年7月，由于MTBE污染，STPUD关闭了贝克斯菲尔德和乡村俱乐部油井。这导致本已紧张的系统失去超过1600gpm的容量。此外，在AH#3井和贝克斯菲尔德井2500英尺范围内的一口哨兵井发现了叔丁醇（TBA）。从2002年6月到2000年7月，对两种颗粒活性炭的功效进行比较。尽管TBA污染可以单独存在，也可以作为MTBE的分解副产品存在，但使用GAC去除TBA的效率超出了中试的范围。 2003年10月，STPUD工程师开始进行广泛研究，以确定GAC和AOP对低水平TBA和MTBE污染的去除效率。本研究结合了STPUD在MTBE高级氧化处理方面的第一手经验，以比较两种技术的操作和经济方面。从加利福尼亚州奥克兰市的美国过滤器公司（U.S.Filter of Oakland，California）获得专利椰壳碳处理系统的提案，以及从加利福尼亚州普莱森特山市的应用工艺技术公司（Applied Process Technology of Pleasant Hill，California）获得专利AOP系统的提案。该研究利用了现有AH#3 AOP设施的全面设计、施工和运营成本数据，而GAC方案是根据已知和估计的硬成本、美国过滤器公司、博伊尔工程公司和其他水务公司提供的信息进行估算的。还进行了广泛的文献研究，以帮助确定每种技术的基础设施需求和操作特性。 成本数据基于资本、运营和维护费用的15年净现值，基于MTBE和TBA的九种可能发生情况。由于太浩湖流域的环境敏感性，现场影响也是一个重要考虑因素。本报告提供了比较的定量和定性结果。包括16个参考文献、表格和图表。

The South Tahoe Public Utility District (STPUD) purchased, permitted and installed California's first-ever advanced oxidation process (AOP) treatment system utilizing O₃/H₂O₂ to treat MTBE-contaminated groundwater for use as drinking water at its Arrowhead Well No. 3 (AH#3) in 2002. In July 2003, the STPUD shut down its Bakersfield and Country Club Wells, due to MTBE contamination. This resulted in a loss of over 1,600gpm capacity for an already stressed system. In addition, tert-butyl-alcohol (TBA) was discovered at a sentinel well within 2,500 feet of both AH#3 and Bakersfield wells. From June 2000 through July 2002, the District retained Boyle Engineering of Fresno, California to conduct a study to compare the efficacy of two types of granulated activated carbons (GAC). Although TBA contamination can be present either independently or as a breakdown byproduct of MTBE, the removal efficiency of TBA using GAC was beyond the scope of the pilot test. In October 2003, STPUD engineers began conducting an extensive study to determine the removal efficiency of GAC and AOP for low-level TBA and MTBE contamination. This study incorporates STPUD's first-hand experience with advanced oxidation treatment of MTBE to compare the operational and economic aspects of both technologies. Proposals were solicited from U.S. Filter of Oakland, California for their proprietary coconut shell carbon treatment system, and from Applied Process Technology of Pleasant Hill, California for their patented AOP system. The study utilized full-scale design, construction, and operating cost data from the existing AH#3 AOP facility, while the GAC option was estimated based upon known and estimated hard costs, information provided by U.S. Filter, Boyle Engineering, and other water utilities. Extensive literature research was also conducted to help determine infrastructure requirements and operational peculiarities of each technology. Cost data were based upon 15-year net present value for capital, operational, and maintenance expenses based upon nine probable occurrence scenarios of MTBE and TBA. Due to the environmental sensitivity of the Lake Tahoe basin, site impacts were also a significant consideration. This report provides the quantitative and qualitative results of the comparison.
