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 2 2009 The 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 GAC unit was two steel drums each containing 180 kg (400 lb) of GAC. 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。GAC单元是两个钢桶，每个钢桶含有180公斤（400磅）的GAC。 The granular activated carbon (GAC) unit and groundwater pump and treatment process are typically employed in environmental remediation to extract and treat contaminated groundwater. This process is particularly suitable for applications at sites like military bases, where groundwater may be polluted with various contaminants. The GAC effectively adsorbs organic compounds, thereby purifying the water. The entire pump and treat system (PTS), inclusive of the GAC unit, is designed for the sustained reduction of pollutant concentrations, providing both rapid initial cleanup and longer-term remediation of contaminated sites. 颗粒活性炭(GAC)单元和地下水抽提处理工艺通常用于环境修复中，用于抽取和处理受污染的地下水。该过程特别适用于像军事基地这样的场所，那里的地下水可能被各种污染物污染。GAC有效地吸附有机化合物，从而净化水质。整个抽提和处理系统（PTS），包括GAC单元，旨在持续降低污染物浓度，提供从快速初步清洁到长期修复受污染场地的效果。 VmRdbod7ro6siixCeFocCEx5nud.png Unit process, single operation None 无 None 无 None 无 None 无 None 无 Life-Cycle Case Study Comparison of Permeable Reactive Barrier versus Pump-and-Treat Remediation Life-Cycle Case Study Comparison of Permeable Reactive Barrier versus Pump-and-Treat Remediation When utilizing this data set for environmental impact assessment or life cycle assessment (LCA), consider the following: 1) Ensure the GAC unit modeling aligns with the specific site conditions and pollutant types present at the site being assessed. 2) Take into account that the effectiveness of the GAC may diminish over time and may require regeneration or replacement, which should be included in the overall assessment. 3) Emissions or other environmental impacts not included in the dataset should be estimated using available literature or fundamental environmental engineering principles. 4) Omitted data must be noted, and assumptions and estimations should be justified within the assessment report. 使用此数据集进行环境影响评估或生命周期评估(LCA)时，请考虑以下几点：1）确保GAC单元建模与评估现场存在的具体场地条件和污染物类型相符。2）考虑到GAC的有效性可能随时间减弱，可能需要再生或更换，这应当纳入整体评估中。3）数据集中未包含的排放或其他环境影响应使用现有文献或基本环境工程原理来估计。4）省略的数据必须在评估报告中注明，并对假设和估算给出理由。 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.cn yangxt@caep.org.cn yangxt@caep.org.cn 2024-03-25T15:39:23+08:00 2024-04-20T15:03:23.538016+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=79223208-918d-4a64-850b-8eb5199ea445&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses Steel Input 50.0 50.0 Measured GAC Unit Stecl Activated Carbon Input 180.0 180.0 Measured GAC Unit GAC Granular active carbon unit Output 1.0 1.0 Measured
