The vacuum extraction allows liquid flow rates to be increased around the extraction well, due to the increased pressure gradient from the groundwater being drawn downward. Lowering the pressure around the well in the subsurface also allows the non-aqueous phase liquid to volatilize more easily. The volatilized contaminants are removed from the subsurface via extraction wells. The extracted soil vapor, non-aqueous phase liquids and groundwater are treated on the surface via gas and liquid treatment trains. 多相抽提是一种同时提取土壤蒸气、非水相液体和地下水的修复技术。由于地下水向下抽取的压力梯度增加，真空抽取允许抽取井周围的液体流速增加。降低地下井周围的压力也允许非水相液体更容易挥发。挥发的污染物通过提取井从地下去除。提取的土壤蒸汽、非水相液体和地下水通过气体和液体处理系统在地表进行处理。 The functional unit in this study is the removal of approximately 80% of the estimated 500 metric tons of contaminant mass from a subsurface soil volume of approximately 40,000 cubic meters and can be achieved. 26 2015 Publication time of literature 文献发表时间 SRI Biochim is a 2 ha site located in the 250 ha industrial zone of Vilvoorde-Machelen just north east of Brussels. SRI Biochim是一个2公顷的场地，位于布鲁塞尔东北部Vilvorde Machelen 250公顷的工业区。 The duration of treatment and total energy budget of the MPE system have been calculated based on the pilot study performed on the SRI Biochim site. The MPE system will require 15 years of operation, which is a conservative estimation. Some of the on-site components and parts that make up the soil vapor and groundwater treatment train will need to be replaced within the 15 years. MPE系统的治疗持续时间和总能量预算是根据在SRI Biochim现场进行的试点研究计算的。MPE系统需要运行15年，这是一个保守的估计。构成土壤蒸汽和地下水处理机组的一些现场部件将需要在15年内更换。 The technical usage of the described industrial process is primarily for in-situ soil remediation. Specifically, the multiphase extraction method is applied to contaminated land areas. It serves to effectively extract contaminant masses, such as soil vapor and non-aqueous phase liquids, from a large volume of subsurface soil, thereby returning the land to a non-hazardous state suitable for future use or redevelopment. 所描述的工业过程的技术用途主要用于原位土壤修复。具体来说，多相抽提方法被应用到被污染的土地区域。它有效地从大量的地下土壤中提取出污染物质量，如土壤蒸汽和非水相液体，从而使土地恢复到适合未来使用或再开发的非危险状态。 ATtRbuaY6oSK8uxHK6DcfYVqn5b.png Unit process, black box None 无 None 无 None 无 None 无 None 无 Beames B., et al.

Accounting for land-use efficiency and temporal variations between brownfield remediation alternatives in life-cycle assessment. Journal of Cleaner Production 101 (2015) 109e117 When utilizing the Life Cycle Assessment data for the in-situ Multiphase Extraction process, it is essential to incorporate the operational duration of the MPE system, which is conservatively estimated at 15 years. Note the requirement for replacement of some components within this timeframe. It's crucial to account for all primary raw materials and the essential energy consumption in the input-output flow calculations. The functional unit for this data set is the removal of an estimated 80% of contaminants from approximately 40,000 cubic meters of subsurface soil, which should be factored into the overall assessment. 在使用原位多相抽提过程的生命周期评价数据时，必须计入 MPE 系统的运行持续时间，保守估计为 15 年。注意这一时间段内某些组件的替换需求。在输入输出流计算中，必须计入所有主要原材料和必要的能源消耗。该数据集的功能单位是从大约 40,000 立方米的地下土壤中去除估计 80% 的污染物，这应该被纳入整体评估中。 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 Yang Xintong, yangxt@caep.org.cn 杨欣桐, yangxt@caep.org.cn yangxt@caep.org.cn yangxt@caep.org.cn 2024-03-25T15:51:51+08:00 2024-04-20T15:03:39.503898+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=7f19db59-835c-490d-9128-79a1e2696fa3&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 Polyethylene,Polyethylene Input 3930.25 3930.25 Measured For 3m Extraction wells, the amount of original useage is3.95t.
