20.500.12556/DKUM-40251 PONOVNA UPORABA OBDELANE ODPADNE VODE V PROCESU BARVANJA RE-USE OF TREATED WASTEWATER IN THE DYEING PROCESS V magistrski nalogi smo poskušali ugotoviti, v kolikšni meri je odpadna voda iz tekstilne tovarne Svilanit primerna za ponovno uporabo v procesu barvanja potem, ko smo jo obdelali z naprednim oksidacijskim postopkom (AOP). Eksperimentalno delo smo razdelili v dva sklopa. V prvem smo se osredotočili na študij učinkovitosti razbarvanja šestih obarvanih industrijskih odpadnih vod z naprednim oksidacijskim UV/H2O2 postopkom. V drugem sklopu smo se posvetili možnosti ponovne uporabe očiščene vode v procesu barvanja, kar smo preverjali z ugotavljanjem kvalitete obarvanega tekstilnega materiala s pomočjo barvne metrike. Na podlagi rezultatov smo ugotovili, da smo z UV/H2O2 postopkom dosegli zelo dobre rezultate znižanja absorbance in celotnega organskega ogljika (TOC), ko smo obdelavali odpadne vode z nizko začetno absorbanco in prevodnostjo. Pri bolj koncentriranih odpadnih vodah z visoko začetno absorbanco in prevodnostjo bi bilo potrebno UV/H2O2 postopek kombinirati z drugimi tehnologijami čiščenja kot so membranske filtracije: ultrafiltracija (UF), mikrofiltracija (MF) ali reverzna ozmoza (RO). Na ta način predvidevamo, da bi lahko znižali TOC do stopnje, ko bi bila voda primerna za ponovno uporabo. Zaključimo lahko, da so le nekateri izpusti odpadne vode tovarne Svilanit, obdelane z AOP, primerni za ponovno uporabo v procesu barvanja, druge bi bilo potrebno očistiti z dodatnimi metodami ali jih uporabiti pri postopku izpiranja ali pranja. In the thesis, we attempted to determine if the wastewater from the textile factory Svilanit is suitable for reuse in the process of dying after being treated with the AOP process. The experimental work was divided into two parts. In the first part, we focused on the study of the effectiveness of decoloration of six-colored industrial wastewaters by UV/H2O2 advanced oxidation process. In the second part we examined the possibility of re-using the treated water in the dyeing process. The quality of colored textile material was studied by colorimetry. We found that absorbance and TOC reduction by the UV/H2O2 process led to very good results in less concentrated wastewaters with low initial absorbance and conductivity. In more concentrated wastewaters with high initial absorbance and conductivity, this method should be combined with another (eg MBR). In this way, the TOC can be reduced to the point where the water is suitable for re-use. We can conclude, that only some discharges of wastewater from the textile factory Svilanit treated with AOP, are suitable for re-use in the process of dyeing, others needed to be cleaned by another method or the cleaned wastewater can be used in the rinsing or washing steps. tekstilna odpadna voda razbarvanje UV/H2O2 postopek vodikov peroksid ekološki parametri absorbanca recikliranje ponovna uporaba obdelane odpadne vode barvanje barvna metrika. textile wastewater decoloration UV/H2O2 process hydrogen peroxide ecological parameters absorbance recycling re-use of treated wastewater dyeing colorimetry. true true false [R.
