A PTS provides quick initial reductions in contaminant concentrations, but often results in a slow, steady reduction for the long-term.PTS通过抽取和使用地上处理设施清除受污染的地下水。PTS处理导致的污染物浓度的降低在初始很快，但通常会导致长期缓慢、稳定的降低0The case study was conducted using publicly available design documents for two remediation strategies designed by Battelle for Dover Air Force Base (AFB) in Dover, DE该案例研究使用了巴特尔为位于美国多佛空军基地The PTS was modeled with five subsystems: extraction wells, air-stripping unit (ASU), catalytic oxidation unit (COU), granular activated carbon (GAC) unit, and treatment facilities.The model COU was modeled as a fixed bed reactor made out of aluminum and steel, with catalyst, and electric heaters.抽出处理由五个单元系统组成：抽提井、气提单元（ASU）、催化氧化单元（COU）、颗粒活性炭单元（GAC）和处理设施。COU单元被建造为由铝和钢制成的固定床反应器，带有催化剂和电加热器。The catalytic oxidation unit is typically implemented for the treatment of contaminated groundwater at industrial and military sites, such as the remediation strategy designed for Dover Air Force Base. It is utilized for reducing pollutants in groundwater to address environmental contamination issues. The unit, when combined with air stripping, granular activated carbon treatment, and other treatment facilities, forms a comprehensive groundwater pump and treatment system (PTS) that offers initial quick reductions and long-term steady contaminant concentration decreases.催化氧化单元通常用于工业和军事场所（如为多佛空军基地设计的修复策略）处理受污染的地下水。它用于减少地下水中的污染物，以解决环境污染问题。该单元与空气剥离、颗粒活性炭处理和其他处理设施结合，形成一个综合的地下水抽出和处理系统（PTS），提供初始的快速降低和长期稳定的污染物浓度降低。VmRdbod7ro6siixCeFocCEx5nud.pngUnit process, single operationNone无None无None无None无None无Life-Cycle Case Study Comparison of Permeable Reactive Barrier versus Pump-and-Treat RemediationLife-Cycle Case Study Comparison of Permeable Reactive Barrier versus Pump-and-Treat RemediationWhen using the LCA data set for the catalytic oxidation unit process, ensure you account for the system boundaries and any limitations in the data set such as omitted inputs or emissions. Consider augmenting the LCA with additional inputs and outputs from literature or calculations based on fundamental principles where data gaps are identified. Caution should be taken to only apply this data in the context of similar environmental remediation scenarios where groundwater contamination is addressed using a pump and treatment strategy. The technological applicability of the data is specific to groundwater remediation processes with elements similar to those described in the Dover AFB case study.使用催化氧化单元过程的生命周期评估数据时，请确保您考虑了系统边界和数据集中的任何限制，例如省略的输入或排放。在确定数据空白时，考虑从文献或基于基本原理的计算中补充额外的输入和输出。应注意仅在使用抽水和处理策略解决地下水污染的类似环境修复场景中应用此数据。数据的技术适用性特定于具有与多佛空军基地案例研究中描述的类似元素的地下水修复过程。Unit processes with inputs or emissions that were not included in the databases were estimated from available literature, calculated using fundamental principles, or omitted.具有未包含在数据库中的输入或排放的单元过程是根据现有文献估计的，使用基本原理计算的，或省略的。Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044.清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。Tiangong LCI Data Working Group天工LCI数据工作小组Yang Xintong, yangxt@caep.org.cn杨欣桐, yangxt@caep.org.cnyangxt@caep.org.cnyangxt@caep.org.cn2024-03-25T15:38:55+08:002024-04-20T15:03:23.533409+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=d5190fb0-187f-4ea4-82ad-42b1644cf445&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and usesAir stripping unitOutput1.01.0MeasuredAluminium and aluminium alloy productsInput110.0110.0MeasuredAir Stripping Unit AluminumPolyethylene,PolyethyleneInput330.0330.0MeasuredAir Stripping Unit HDPESteelInput50.050.0MeasuredAir Stripping Unit Steel (Blower)
