Evaluating UV Disinfection and Advanced Oxidation Processes for Cincinnati's Richard Miller Treatment Plant 评估辛辛那提理查德·米勒处理厂的紫外线消毒和高级氧化工艺
发布日期: 2008-11-01
大辛辛那提水厂(GCWW)最近完成了理查德·米勒处理厂(RMTP)的紫外线(UV)工艺总体规划(UVMP) 确定实施紫外线处理技术的最佳方式,以解决消毒和消毒问题 未来20年内微污染物质的破坏。具体治疗目标包括: 加强隐孢子虫和新出现微生物病原体的消毒 灭活; 高级氧化用于控制季节性味道和气味(特别是MIB还原);和 高级氧化法用于销毁俄亥俄河中新出现的污染物, 包括上述四种化学污染物。 UVMP评估了大量设计备选方案,包括:15紫外线消毒和紫外线消毒 高级氧化工艺(UV/AOP)设计方案; 三处厂址;还有,两个 工艺生产线位置(GAC前和GAC后)。目的是找出所有可能的 针对RMTP的紫外线消毒和AOP技术的组合 对其进行评估和排序,并选择一个或多个备选方案,以指导产品的最终设计 RMTP的紫外线设施。还进行了基准分析,以比较UV/AOP设计 臭氧/过氧化氢AOP工艺的替代品,因为后者是公认的 城市饮用水应用的AOP工艺。这些评估的结果如下所示 本文提出。 紫外线过程模拟模型(UVCAT)与紫外线传感器的输入结合使用 供应商和预测消毒和高级氧化处理的文献综述 各种设计方案的性能。UVCAT评估的结果如下所示 本文对此进行了总结,并在一篇配套论文中进行了更详细的讨论(Wright等人,2008年)。包括参考资料、表格、图表。
Greater Cincinnati Water Works (GCWW) recently completed an ultraviolet (UV) process master plan (UVMP) for the Richard Miller Treatment Plant (RMTP) to identify the best way to implement UV treatment technologies to address both disinfection and micropollutant destruction over the next 20 years. Specific treatment objectives included: enhanced disinfection for Cryptosporidium and emerging microbial pathogen inactivation; advanced oxidation for seasonal taste and odor control (specifically MIB reduction); and, advanced oxidation for destruction of emerging contaminants in the Ohio River, including the four chemical contaminants cited above. The UVMP evaluated a large matrix of design alternatives including: 15 UV disinfection and UV advanced oxidation process (UV/AOP) design alternatives; three plant site locations; and, two process train locations (pre-GAC and post-GAC). The intent was to identify all possible combinations of UV-based disinfection and AOP technologies for RMTP, systematically evaluate and rank them, and select one or more alternatives for guiding the final design of the UV Facility for RMTP. A benchmark analysis was also performed to compare UV/AOP design alternatives against the ozone/peroxide AOP process, since the latter is well established as an AOP process for municipal drinking water applications. The results of these evaluations are presented in this paper. A UV process simulation model (UVCAT) was used in conjunction with input from the UV vendors and a literature review to predict disinfection and advanced oxidation treatment performance for the various design alternatives. The results of the UVCAT evaluations are summarized in this paper, and discussed in more detail in a companion paper (Wright, et. al, 2008). Includes reference, tables, figures.
