Wastewater influent and effluent concentrations from on-site package plants in Northern Sweden and Finland
收藏资源简介：
The data contains influent and effluent concentrations of traditional parameters measured in on-site package plants for domestic wastewater treatment serving single houses or small communities (2-30 person equivalent). The parameters analysed include organic matter, suspended solids, nutrients (phosphorus and nitrogen compounds) and indicator bacteria, as well as other physicochemical parameters such as temperature, pH and turbidity, and chloride as a tracer compound to detect dilution effects. Additional influent and effluent concentrations of micropollutants from two slightly larger plants (serving 12-30 person equivalent) are also included. These micropollutants consisted of 19 selected pharmaceuticals, caffeine and the sweetener Acesulfame K, and 15 phthalates. The purpose of the collected dataset was to investigate the treatment efficiency of package plants operating in cold climate conditions throughout different seasons. The samples were collected in the northern regions of Sweden (Norrbotten) and Finland (North Ostrobothnia and Lapland) characterised by low winter temperatures and deep frost penetration. The data has not been processed and consists of results (raw data) obtained directly from our university laboratory in Luleå university of technology (nutrient samples) and accredited laboratories (traditional parameters, microbiology, micropollutants). The data contains influent and effluent concentrations of traditional parameters measured in on-site package plants for domestic wastewater treatment serving single houses or small communities (2-30 person equivalent). The purpose of the collected dataset was to investigate the treatment efficiency of package plants operating in cold climate conditions throughout different seasons. The samples were collected in the northern regions of Sweden (Norrbotten) and Finland (North Ostrobothnia and Lapland) characterised by low winter temperatures and deep frost penetration. The investigated facilities included six package plants operated in continuous mode: one with a trickling filter (TF), one with a rotating biological contactor (RBC) and four with activated sludge with phosphorus removal by coagulation (ASC) or alkaline filter (ASF1, ASF2, ASF3) systems. Additionally, five plants supplied by three different manufacturers operated in batch mode with activated sludge and coagulation for phosphorus removal (SBR1-5). The parameters analysed include organic matter (BOD), suspended solids (TSS), nutrients (phosphorus and nitrogen compounds) and indicator bacteria, as well as other physicochemical parameters such as temperature, pH and turbidity, and chloride as a tracer compound to detect dilution effects. Additional influent and effluent concentrations of micropollutants from two slightly larger plants (ASC and TF, serving 12-30 person equivalent) are also included. These micropollutants consisted of 19 selected pharmaceuticals, caffeine and the sweetener Acesulfame K, and 15 phthalates. The data set contains multiple files: -A main excel file called "Wastewater_package_plants" containing the numerical results of influent and effluent concentrations of traditional parameters and selected micropollutants. - Three excel files called "Wastewater temp data..." containing temperature data logged continuously with a temperature sensor (placed in the biological treatment unit) at three different package plants - Two text files called "SMHI Air temp data..." with air temperature data retrieved from the Swedish meteorological institute (SMHI) to be used with the wastewater temperature data All the excel files are provided in xlsx and csv format.
本数据集涵盖了服务于单户住宅或等效2-30人小型社区的生活污水处理一体化现场装置（package plant）的常规参数进水（influent）与出水（effluent）浓度检测数据，同时包含两台等效服务12-30人的稍大规模一体化装置的微污染物进出水浓度数据。本次分析的常规参数包括有机物、悬浮固体（suspended solids）、营养盐（磷及氮化合物）、指示菌，以及温度、酸碱度（pH）、浊度等理化参数，同时以氯化物作为示踪剂（tracer compound）以监测稀释效应；所涉微污染物包括19种目标药物类污染物（pharmaceuticals）、咖啡因及甜味剂安赛蜜（Acesulfame K），以及15种邻苯二甲酸酯（phthalates）。 本数据集的采集目的为探究寒冷气候条件下不同季节运行的一体化污水处理装置的处理效能。样本采集于瑞典北部的北博滕区（Norrbotten）以及芬兰的北奥斯特罗波的尼亚省和拉普兰地区，该区域冬季气温低下且冻土层深厚。 本次调研的处理设施共包含11台一体化污水处理装置：其中6台采用连续运行模式，分别为1台滴滤池（trickling filter, TF）工艺装置、1台旋转生物接触器（rotating biological contactor, RBC）工艺装置，以及4台活性污泥除磷工艺装置（含混凝除磷工艺装置ASC与碱性过滤除磷工艺装置ASF1、ASF2、ASF3）；另有5台由三家不同厂商供应的间歇运行式装置，采用活性污泥混凝除磷工艺，编号为SBR1-5。 本数据集全部为未经过预处理的原始检测数据，分别由吕勒奥理工大学（Luleå University of Technology）校内实验室负责营养盐样本的检测，经认可的第三方实验室负责常规参数、微生物学指标及微污染物的检测。 本数据集包含多个文件： 1. 主Excel文件"Wastewater_package_plants"，包含常规参数及目标微污染物的进水、出水浓度数值结果； 2. 三份名为"Wastewater temp data..."的Excel文件，记录了三台不同一体化污水处理装置的生物处理单元内连续采集的温度传感器数据； 3. 两份名为"SMHI Air temp data..."的文本文件，数据来源于瑞典气象水文研究所（Swedish Meteorological and Hydrological Institute, SMHI），用于配合污水处理温度数据开展分析。 所有Excel文件均提供xlsx及csv两种格式。
