Batch test for measurement of biodegradable and inert COD fraction concentrations in municipal waste waters using UV-Vis senors

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).
