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至2014年间开展的生物滞留柱（bioretention column）试验的全部原始数据。本次试验采用中试规模柱体装置，以合成暴雨雨水（synthetic stormwater）作为进水进行配水。研究人员采集进水（influent）与出水（effluent）水样，针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、电导率等配套监测参数。 本数据集可用于量化生物滞留设计因素（如淹没区（submerged zone））与环境因素（雨水进水盐度、温度）对生物滞留系统污染物去除效果的影响。所有滤柱均采用统一的柱体设计、滤料及雨水配制方案，保障不同试验间具备良好的可比性。数据集包含合成暴雨雨水进水浓度与生物滞留出水浓度数据，同时完成了滤料与植物组织中的金属浓度分析。 本数据集可用于进一步分析生物滞留系统的运行性能，与其他地区开展的同类研究进行对比，亦可用于生物滞留污染物去除性能及相关过程的建模研究。相关研究成果已发表于学术期刊（详见【出版物】板块）。 请参阅以下文档文件： - SummarisingDescription.pdf：试验概况说明文档，包含柱体设计示意图 - SummarisingTable.xlsx：试验总览表，涵盖研究概况、检测污染物与影响因素等内容，该表详细说明了各数据文件的构成。 关于试验设计与方法的更多细节，可查阅相关学术期刊论文。
