Abstract:Voda kot ključni sestavni del okolja predstavlja življenjski prostor velikemu številu živali in rastlin. Prav tako je tudi sestavni del vsakega živega bitja, kateremu omogoča normalno delovanje. V odpadni vodi so prisotne snovi, ki lahko ogrožajo naravno ravnotežje, zato jih je potrebno iz nje odstraniti. Eden večjih onesnaževalcev vode je tekstilna industrija, saj so tekstilne odpadne vode trenutno najkompleksnejše med vsemi odpadnimi vodami, saj poleg barvil vsebujejo še različne dodatke, ki so potrebni za izvedbo določenega procesa. Da barvila ne ostanejo predolgo v okolju, jih je potrebno primerno obdelati. Za razbarvanje tekstilnih odpadnih vod se vedno pogosteje uporabljajo napredni oksidacijski postopki AOP (Advanced Oxidation Processes), ki temeljijo na radikalski oksidaciji onesnaževala, s težnjo k popolni mineralizaciji do okolju neškodljivih produktov ali do takšnih intermediatov, ki bi jih bilo nadalje možno obdelati v bioloških procesih. Vodikov peroksid (H2O2) je najpogosteje uporabljeno oksidacijsko sredstvo. Zaradi njegove stabilnosti ga je potrebno v čisti obliki ustrezno aktivirati. Glede na vrsto uporabljenega aktivatorja, poznamo več različnih oksidacijskih postopkov razbarvanja, med njimi je tudi aktivacija s pomočjo ultravijoličnih (UV) žarkov. Po izdelavi eksperimentalnega načrta in obdelavi odpadne tekstilne vode, onesnažene z reaktivnim barvilom C. I. Reactive Blue 268, po zgoraj omenjenem postopku, smo določili najbolj optimalno koncentracijo vodikovega peroksida (H2O2), optimalen pH medija in optimalen čas trajanja izpostavljenosti UV svetlobi.

Title:EXPERIMENTAL DESIGN FOR DECOLORATION OF TEXTILE WASTE WATERS USING ADVANCED OXIDATION PROCESS H2O2/UV
Abstract:Water as a key component of an environment, is a living space for large numbers of animals and plants. It is also an integral part of every living creature to which it allows normal operation. In the waste water the substances are present which may threaten the natural balance, so they need to be removed. One of the major polluters of water is the textile industry. Its waste water is currently the most complex of all waste water managements, as dyes also contain various additives which are necessary for the execution of a specific process. If we don't want the colors to stay in the environment for too long, they must be properly treated. For decolorization of textile effluents advanced oxidation processes AOP (Advanced Oxidation Processes) are increasingly being used based on the radical oxidation of pollutants, with a tendency to complete mineralization of environmentally sound products or to such intermediates, which could further be treated in biological processes. Hydrogen peroxide (H2O2) is the most commonly used oxidizing agent. Due to its stability it is necessary to properly activate its pure form. Given the type of activator, there are several different oxidation dyeing processes, among them activation by ultraviolet (UV) rays. After the development of experimental design and processing of textile waste water contaminated with reactive dye C. I. Reactive Blue 268, according to the above-mentioned process, we determined the optimal concentration of hydrogen peroxide (H2O2), the optimal pH of the medium and the optimal duration of exposure to UV light.
