Dataset on stormwater bioretention column studies: Impact of temperature, salt and a submerged zone on the removal of metals, nutrients and suspended solids

This data set presents the full raw data from bioretention column studies conducted at Luleå University of Technology in 2010-2014. The pilot scale columns were watered with synthetic stormwater. Influent and effluent samples were collected and analysed for pollutants including total and dissolved metals, nutrients, pathogens and suspended sediment. Further, supporting parameters (e.g. pH, conductivity) are included. The data enables quantifying the impact of bioretention design factors (submerged zone) and ambient factors (salinity in stormwater inflow, temperature) on the removal of these pollutants by bioretention. All filters utilised the same general column design and filter material as well as stormwater preparation. This enables inter-comparability between the different studies. Synthetic stormwater inflow concentrations and bioretention effluent concentrations are presented in the data set. Further, metal concentrations in the filter material and plant tissue have been analysed. The data set enables further analyses of bioretention performance, comparison with similar work performed elsewhere and can be used in modelling of bioretention removal performance and processes. Scientific papers describing the data have been published (see Publications) See documentation files: - SummarisingDescription.pdf - summarising description of experiments incl. an illustration of column design - SummarisingTable.xlsx - table with overview of studies and included parameters (pollutants) and factors. The table describes the content of each data file. Further information on experimental design and methods are available in the related scientific journal publications.本数据集收录了吕勒奥理工大学（Luleå University of Technology）2010—2014年间开展的生物滞留柱试验完整原始数据。 试验采用中试规模柱体，以合成暴雨径流作为进水补给。研究人员收集进水与出水样品，对总金属与溶解态金属、营养盐、病原体及悬浮沉积物等污染物开展检测分析，同时纳入pH、电导率等辅助监测参数。 本数据集可用于量化生物滞留设计因素（淹没区）与环境因素（暴雨径流进水盐度、温度）对生物滞留系统去除上述污染物效果的影响。所有过滤装置采用统一的柱体设计、滤料配置及暴雨径流制备方案，保障不同试验间具备可比性。 数据集包含合成暴雨径流进水浓度与生物滞留柱出水浓度数据，同时对滤料及植物组织中的金属浓度进行了检测分析。本数据集可用于进一步开展生物滞留系统性能分析、与其他同类研究进行横向对比，亦可应用于生物滞留污染物去除性能与过程的建模研究。目前已有相关科学论文对本数据集进行了详细阐述（详见Publications部分）。 可参阅以下说明文件： - SummarisingDescription.pdf：试验概况说明文档，包含柱体设计示意图 - SummarisingTable.xlsx：汇总各研究及纳入参数（污染物）与影响因素的表格，该表格对各数据文件的内容进行了详细说明。 更多试验设计与方法细节可查阅相关学术期刊发表的论文。
