摘要/Abstract

摘要： 在国家“双碳”战略背景下，生物堆修复技术的绿色可持续水平评价显得尤为重要。基于生命周期评价软件eFootprint和工程案例，从环境影响角度评价了某焦化土壤生物堆修复技术的绿色可持续性。结果表明：焦化土壤生物堆修复技术绿色可持续性总体较好，人体毒性(HT)、水资源消耗(WU)、生态毒性(ET)、全球增温潜势(GWP)、可吸入无机物(RI)、非生物质资源消耗潜值(ADP)、酸化潜值(AP)、初级能源消耗(PED)、竞争-土地使用(CLU)、富营养化潜值(EP)对环境影响相对较高且差别不大(贡献率为94.90% ~ 100%)，臭氧层消耗(ODP)对环境影响稍弱(贡献率为68.53%)；影响环境(HT，WU，ET，GWP，RI，ADP)的主要物料清单因素为气体通入量、CO₂产生量、尿素投加量和风机耗电量。选择营养全面、含水率（w）大于10%的焦化场地，优化最小风量设计以及配备合适风机型号等措施可提升焦化土壤生物堆修复技术的绿色可持续性。研究结果可为有机污染土壤生物堆修复技术绿色可持续性的提升提供一定的理论基础和技术参考。

Abstract: Under the background of the national "dual carbon" strategy, the evaluation of the green-sustainability level of bio-pile remediation technology is more important. Based on the life cycle assessment (LCA) software eFootprint and a practical engineering case of bio-pile remediation at a coking contaminated site, the green-sustainability level of bio-pile technology is evaluated from environmental impact. The results indicate that the overall green-sustainability level of bio-pile on coke-contaminated soil is high. The environment-impact values of human toxicity (HT), water use (WU), ecotoxicity (ET), global warming potential (GWP), respiratory inorganics (RI) and abiotic depletion potential (ADP), acidification (AP), primary energy demand (PED), competition-land use (CLU) and eutrophication potential (EP) are relatively higher and their difference is not significant (contribution ratio is 94.90% -100%), whereas that of ozone depletion potential (ODP) is relatively lower (contribution ratio is 68.53%). The main material factors that cause major environmental impacts (HT, WU, ET, GWP, RI, ADP) and reduce its green sustainability are input air volume, CO₂ volume produced, urea dose, and flower power consumption. To further enhance the green sustainability of soil bioremediation technology, measures can be taken such as selecting coke-contaminated soil with comprehensive nutrition and moisture content greater than 10%, optimizing the minimum air-flow volume design, and selecting appropriate flower type to ensure lower power output. The results of this paper can provide some theoretical basis and technical reference for the improvement of green sustainability of bioremediation technology of organic contaminated soil.
