The impermeable funnel guides or collects polluted groundwater flow into the gate. The gate is filled with active materials to dispose of the groundwater flowing through it. Caisson-based gate refers to a gate installed using the caisson-based method. 导水门是地下水渗透性反应墙的组成部分之一，隔水漏斗将污染地下水流引导或汇集进入导水门，导水门内填充通过活性材料，用于使流经的地下水得到处置。沉箱式导水门指采用沉箱法安装的导水门。 9 2011 PRB is assumed to be installed at a simulated site 假设的污染场地 The caisson-based gate described is employed as a component within a permeable reactive barrier (PRB) system for in-situ groundwater remediation. Its function is to direct contaminated groundwater through an impermeable funnel into the gate, where it is then treated by passing through reactive materials within the gate. The term 'caisson-based' refers to the installation process of the gate, which involves the use of the caisson method, a technique that allows for the construction of the gate in an underwater environment. 沉箱式导水门被用作渗透性反应墙系统（PRB）的一个组成部分，用于原位地下水修复。它的作用是通过隔水漏斗将污染地下水引导到导水门中，然后通过导水门内的活性材料处理污染水。'沉箱式'一词指的是导水门的安装工艺，该工艺采用沉箱方法，这是一种允许在水下环境中构建导水门的技术。 PdQ4bwBuhoQ1hXx1xuocEsyOnkd.png Unit process, single operation None 无 None 无 None 无 None 无 None 无 Mark S.

Lo.Environmental Life Cycle Assessment of Permeable Reactive Barriers: Effects of Construction Methods, Reactive Materials and Groundwater Constituents[J].Environmental Science & Technology 2011, 45, 23, 10148-10154 When using this dataset, ensure to model the in-situ groundwater remediation process accurately by considering the unique installation methodology of the caisson-based gate, its diameter, and the nature of the reactive materials used within the gate. The dataset includes all major raw materials and essential energy consumption, which should be accounted for in the life cycle assessment. Users should note the functional unit of the process – a single operation – and its application to a simulated polluted site for PRB installation. 使用此数据集时，需准确模拟沉箱式导水门的原位地下水修复过程，考虑其独特的安装方法、直径以及导水门内使用的反应材料的性质。数据集包含了所有主要原材料和必要的能耗，这些都应在生命周期评估中予以考虑。用户应注意过程的功能单位——单一操作——及其在污染场地的模拟PRB安装中的应用。 All maior raw materials and all the essentialenergy is ncuded. 输入输出流包括所有主要原材料和所有必要的能源消耗 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 Zhang Jianbin, zhangjb@caep.org.cn 张建宾, zhangjb@caep.org.cn zhangjb@caep.org.cn zhangjb@caep.org.cn 2024-03-25T14:56:51+08:00 2024-04-20T15:02:24.815679+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=decbb5e5-fcd4-48ca-91be-b403f956399f&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 Zero-valent Iron Input 139000.0 139000.0 Estimated Assume Fe0 is mixed with quartz sand in 1:1 (w:w) quartz sand Input 139000.0 139000.0 Estimated Assume Fe0 is mixed with quartz sand in 1:1 (w:w) transport in t*km Input 44480.0 44480.0 Estimated Transport distance of the materials to the site is assumed to be 160 km (100 mile) Electricity Input 483000.0 483000.0 Estimated Reactive media construction.
