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 5 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. Model extraction wells were constructed using an eight inch auger (80 kW at 5 m/hour) and were composed of PVC well pipe, filter pack, grout, and a 0.75 kW (1 hp) well pump. 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。提取井使用8英寸螺旋钻（80 kW at 5 m/hour）建造，由PVC井管、滤料、灌浆和0.75 kW (1 hp)泵组成。 The described industrial process involved in the extraction and treatment of contaminated groundwater is utilized for environmental remediation purposes. It is specifically implemented in sites where groundwater pollution poses a significant threat to the environment and human health, such as military bases, industrial sites, and areas with historical chemical spills or leaks. The process is designed to handle the clean-up of contaminated sites through a series of technologically advanced units including extraction wells, air-stripping units, catalytic oxidation units, granular activated carbon units, and treatment facilities. 所描述的工业过程涉及污染地下水的抽取和处理，用于环境修复目的。它特别用于地下水污染对环境和人类健康构成重大威胁的场所，例如军事基地、工业场地以及有历史化学品泄漏或渗漏的地区。该过程设计用于通过包括抽取井、空气提升单元、催化氧化单元、颗粒活性炭单元和处理设施在内的一系列技术先进单元来处理污染地点的清理。 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 dataset for Life Cycle Assessment, users should take into account the specific context of the groundwater remediation process, including the composition and concentration of contaminants, the hydrogeology of the area, and the performance characteristics of the treatment technology involved. It is essential to consider the environmental impact of the construction and operation of the remediation system. Additional data on similar processes or average industry practices should be sought to check the representativeness and validity of the dataset. Where data gaps exist, users should employ conservative assumptions or refer to the most relevant available literature and practices. Emissions that are not accounted for in this dataset should be estimated based on best available techniques, and the omission of such emissions should be clearly documented and justified in the assessment. 在使用此数据集进行生命周期评估时，用户应考虑地下水修复过程的具体情况，包括污染物的组成和浓度、地区的水文地质以及所涉及治理技术的性能特征。必须考虑修复系统建设和运营的环境影响。应寻找关于类似过程或平均行业实践的额外数据，以检查数据集的代表性和有效性。在存在数据空白时，用户应采用保守的假设，或参考最相关的文献和实践。未在该数据集中计算的排放应基于最佳可用技术进行估算，并且在评估中应明确记录和证明这种排放的遗漏。 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 2024-03-25T15:37:56+08:00 2024-04-20T15:03:23.523463+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=3f37008a-20e8-49fa-acbb-964694b1e725&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 polyvinylchloride resin (S-PVC) Input 40.0 40.0 Measured Rxtraction Well pVC Pipe cement, unspecified Input 2000.0 2000.0 Measured Extraction Well Cerment Gravel Sand Input 330.0 330.0 Measured Extraction Well Gravel Steel Input 50.0 50.0 Measured Extraction Well Steel (Pump) Energy, unspecified Input 2300.0 2300.0 Measured Extraction Well Construction Energy Extraction wel Output 1.0 1.0 Measured
