At the same time, air is blown into the bottom for oxygenation, meeting the oxygen needs of microorganisms while allowing them to fully contact pollutants and accelerate their degradation. After degradation is completed, filter and dehydrate the soil 将污染土壤转移至生物反应器，加水混合成泥浆，调节适宜的pH，同时加入一定量的营养物质和表面活性剂，底部鼓入空气充氧，满足微生物所需氧气的同时，使微生物与污染物充分接触，加速污染物的降解，降解完成后，过滤脱水 The functional unit for this study is related to treated soil polluted with petroleum hydrocarbons using bioslurry (100 g, 36.5 kWh). The initial concentration of total petroleum hydrocarbons is 4500 mg/kg. 8 2023 This study is based on indoor experiments, where the author's hometown is filled in. 本研究基于室内试验，该处填写的为作者籍贯。 Degradation studies were conducted in mesocosm consisting of bioslurry reactors using 100 g of soil polluted with diesel oil suspended in 500 mL of distilled water with a 1:5 soil-to-water ratio. They stimulated with 1.5 g NH4Cl and 0.1 g KH2PO4 + 5 g/L of activated sludge + supplemented with crude novel rhamnolipids (275 mL). 1 L Erlenmeyer/conical flasks were used as bioreactors with constant mixing by mechanical mixers at 150 rpm to ensure substrate availability and oxygen transfer for about 20 days. The analyses revealed that the combination of activated sludge, nutrients, and biosurfactant showed a 79.4 % reduction in TPHs after 20 days in the mesocosm experiment. 降解是在由生物泥浆反应器在中试尺度进行的，使用100g悬浮在500ml蒸馏水中的柴油污染的土壤，土壤与水的比例为1:5。它们用1.5g NH4Cl和0.1g KH2PO4+5g/L活性污泥+鼠李糖脂粗品（275毫升）促使反应进行。使用1L锥形烧瓶作为生物反应器，通过机械混合器在150rpm下持续混合以确保底物可用性和氧气转移约20天。分析表明，在中试尺度实验中，活性污泥、营养物质和生物表面活性剂的组合在20天后显示出TPHs减少79.4%。 This detailed LCA data pertains to a laboratory-scale soil remediation process where bioslurry reactors are utilized to treat petroleum hydrocarbon-contaminated soil. The process is suited for experimental research purposes and provides a basis for potential upscaled industrial applications in the environmental engineering sector, such as large-scale soil decontamination projects. 此生命周期评估数据详述了一种实验室规模的土壤修复过程，使用生物泥浆反应器处理石油碳氢化合物污染的土壤。该过程适用于实验研究目的，并为可能的大规模工业应用（如大型土壤净化项目）在环境工程行业提供了基础。 JIGcbKwbFoItfPxENNVcJ7bSnjd.png Unit process, single operation None 无 None 无 None 无 None 无 None 无 Gebregiorgis T A ,Francesca F ,Silvia S , et al.

Users should apply this data for laboratory-level soil remediation scenarios only and not extrapolate to field-level without proper scaling and modifications. The system's low maintenance and resource requirements are specific to the lab setting; large-scale applications will differ significantly. Special attention should be given to the correct proportioning of soils, nutrients, and biosurfactants and continuous monitoring of process parameters such as pH and oxygen transfer rates. It is crucial to consider the inoculum cultivation and chemical usage on upscaling the process, which are excluded in this LCA data set. 用户应该仅将这些数据用于实验室级土壤修复场景，未经适当缩放和修改不得外推至现场级别。系统的低维护和资源要求特定于实验室设置；大规模应用将有显著不同。应特别注意土壤、营养物质和生物表面活性剂的正确配比，并持续监测过程参数，如pH和氧气转移率。在扩大过程中，考虑接种培养和化学品使用至关重要，这些在此生命周期评估数据集中被排除。 Given the lab-scale systems' short time frame and low maintenance requirements, it is anticipated that this study does not involve mainte nance tasks. Large-scale maintenance necessitates a higher use of chemicals, materials, and electricity. Inoculum cultivation is excluded from the assessment. 鉴于本研究为实验室规模，处置时间短，维护要求低，修复系统的维护不包含在本研究中。大规模修复系统的维护需要使用更多化学品、材料和电力。生物接种也被排除在评估范围之外。 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 2024-03-25T14:04:39+08:00 2024-04-20T15:00:40.535016+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=a297c8c9-09c1-4010-a87d-f67d0a43df66&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 Deionized Water Input 0.225 0.225 normal Ammonium Chloride Input 0.0015 0.0015 normal Potassium Dihydrogen Phosphate Input 0.0001 0.0001 normal Biosurfactant Input 0.000225 0.000225 normal Digested Sludge,Digester sludge Input 0.005 0.005 normal Electricity Input 129.6 129.6 normal Wastewater Output 0.0004 0.0004 normal contaminated soil Input 1.0 1.0 Remediated soil Output 1.0 1.0
