| Abstract | In wastewater from the outflow of primary treatment (wastewater treatment plant, Dresden-Kaditz) and from a combined sewer of the city of Dresden, the wastewater composition was determined using in-situ UV-Vis measurement technology and oxygen consumption measurements combinded with the activated sludge model No.1 (ASM No. 1) and wet chemical analyzes from random samples as a reference. This data set was used for the publication of Steffen Weber's doctoral thesis "Fraktionierung des Chemischen Sauerstoffbedarfs mithilfe von Extinktionsmessungen im UV/Vis-Spektralbereich" by Steffen Weber. (link: https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa2-847298). The aim of this work was to extend the system understanding of the wastewater composition beyond the standard analysis parameters by using in situ UV-Vis measurement techniques to determine the COD components (fractionated according to ASM No.1). | |
| Applied methods and techniques | COD fractions were simulated using the model approach from Henze et al. 1986 ("Activated Sludge Model No. 1"). Oxygen uptake rate was calculated and proportionally assigned to the biodegradable COD fractions following the approach of Wentzel et al. 1995 ("Batch test for measurement of readily biodegradable COD and active organism concentration in municipal waste waters"). Reference values for the COD fractions (SS, XS, SI and XI) were calculated from standard analysis results and the approach of Roeleveld and Loosdrecht 2002 ("Experience with guidelines for wastewater characterization in The Netherlands"). Calibration functions determined with partial least squares regression - determining causal relationship between absorbance records and modeled concentrations (SS, XS, SI and XI).
A more detailed explanation of all analysis methods can be found in the dissertation "Fraktionierung des Chemischen Sauerstoffbedarfs mithilfe von Extinktionsmessungen im
UV/Vis-Spektralbereich" of Steffen Weber (link:https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa2-847298) | |

| Content of the research data | Dataset, Model: The collected time series of oxygen concentration and spectrophotometer recordings are provided as raw data. In addition, the data collection contains an ecxel file with analysis results from random sampling - including metadata (time and place of sampling of the wastewater sample, processor, serial number of the spectrophotometer). The data for each respiration test includes results of wet chemical analysis (COD, CODmf, BOD5 and NO3-N), the continuously recorded extinction spectra during the test period and their calculated equivalent concentrations based on the manufacturer's calibration "INFLUENT V160".
The script (R-project) for data preprocessing, application of ASM No. 1, freferencing modeled concentration (COD fractions) and developing calibration functions (using the regression functions partcial-least-squares and Least-Absolute-Shrinkage-and-Selection-Operator) is also part of the upload. | |
