Orgaanisen aineen poistumista j\u00e4tevedenpuhdistamolla mitataan yleisill\u00e4 parametreilla, kuten kemiallisella tai biokemiallisella hapenkulutuksella, joiden avulla ei saada tietoa orgaanisen aineen ominaisuuksista. T\u00e4m\u00e4n ty\u00f6n tavoitteena oli karakterisoida orgaanisen aineen koostumusta tulevassa ja l\u00e4htev\u00e4ss\u00e4 j\u00e4tevedess\u00e4 Nen\u00e4inniemen j\u00e4tevedenpuhdistamolla.

Removal of organic matter is measured by common parameters, such as chemical or biochemical organic matter, which provide no information about characteristics of organic matter. The aim of this study was to characterize organic matter composition in wastewater influent and effluent samples in Nen\u00e4inniemi wastewater treatment plant. The removal of detected compound types and different size fractions and variations in their removals were studied. Poorly removable size fractions of each compound type were distinguished. The organic matter composition of landfill leachate was also investigated as one organic matter load source. High-performance size exclusion chromatography with UV and fluorescence detection was used as characterization method. Aromatic compounds were detected with UV detection, and tyrosine-like, tryptophan-like, fulvic-like and humic-like compounds were detected with fluorescence detection. Tyrosine-like compounds accounted for most of organic matter detected in wastewater influent, whereas in effluent fulvic-like compounds dominated. Removal percentages of tyrosine-like and tryptophan-like compounds were highest, 90 \u00b1 1, and 77 \u00b1 3, respectively, whereas removals of fulvic-like and humic-like compounds were low, 27 \u00b1 4, and 7 \u00b1 5 %, respectively. Amount of fulvic-like and humic-like compounds were increased in some size fractions on average, indicating formation of these compounds during the treatment. Organic compounds in wastewater effluent were likely recalcitrant compounds or formed during the treatment. Landfill leachate contained relatively large amounts of fulvic-like and humic-like compounds. Based on this study, HPSEC-UV-fluorescence is an efficient method to provide for valuable information about organic matter characteristics and compounds which remain in wastewater after treatment.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Riitta Pitk\u00e4nen (rpitkane@jyu.fi) on 2018-06-29T10:31:51Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2018-06-29T10:31:52Z (GMT).
