摘要

本文的目的是利用区域化生命周期比较评估方法，评估区域特征对水平地下流人工湿地环境可持续性的影响。在输入和输出值方面实施了区域化，并考虑了影响评估方法，这些方法考虑了区域因素，以估算环境影响结果。假定对处理城市污水的水平地表下流动人工湿地进行案例研究，并考虑在 5 个不同国家安装人工湿地的情况，对该系统进行评估，这些国家在技术、地理位置、气候条件和电力组合方面具有不同的特点。生命周期比较评估结果表明，各国之间存在很大差异，这突出表明了采用区域化方法对当地具体情况进行适当评估的重要性。在比较不同国家案例研究的生命周期评估时，发现所有区域化影响类别的平均相对标准偏差为 59%。因此，该研究成功地表明了区域化在湿地建设任务中的重要性，并提供了相关的系统改进建议，以根据区域特点减少对环境的影响。

Assessing the effect of local characteristics on environmental impacts of Constructed Wetlands by regionalized life cycle assessment

The goal of this paper is to assess the effect of regional characteristics on the environmental sustainability of Horizontal Subsurface Flow Constructed Wetlands using comparative regionalized Life Cycle Assessment. Regionalizaton was implemented in terms of input and outputs values, as well as considering impact assessment methods that consider regional aspects to estimate the environmental impact results. A case study for a Horizontal Subsurface Flow Constructed Wetlands treating municipal wastewater was assumed, and the system was assessed considering the installation of the constructed wetland in 5 different countries with distinct characteristics in terms of technologies, geographic location, climate conditions and electricity mix. The comparative life cycle assessment results showed important variations among the countries, which highlights the importance of taking into account a regionalized approach in order to assess the local specificities properly. An average relative standard deviation of 59 % for all regionalized impact categories was identified when comparing the LCA for the case study for different countries. So, the study successfully showed the importance of regionalization in constructed wetlands assignments and provided relevant recommendations for system enhancements in order to reduce environmental impact according to regional characteristics.

期刊介绍： Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
