20.500.12556/DKUM-77169 Preučevanje vplivnih dejavnikov za izboljšanje koagulacije industrijske odpadne vode diplomsko delo visokošolskega strokovnega študijskega programa I. stopnje A Study of the Influential Factors for Improving Industrial Wastewater Coagulation Za industrijsko odpadno vodo je značilna zelo raznolika kemijska sestava. Veliko težavo predstavljajo predvsem visoke vrednosti težkohlapnih lipofilnih snovi (TLS) ter anionskih in neionskih tenzidov. Toksičnost industrijske odpadne vode lahko zmanjšamo s pomočjo fizikalno-kemijskih metod čiščenja, kot so koagulacija, biološke metode in napredni oksidacijski postopki. Cilj diplomskega dela je določiti uspešnost čiščenja različnih industrijskih odpadnih vod s postopkom koagulacije/flokulacije in naprednimi oksidacijskimi postopki pri različnih pogojih. Nadaljnji cilj je analizirati učinkovitost glede na prvo in drugo fazo čiščenja različnih odpadnih vod ter predpostaviti najboljše kombinacije čiščenja. Osredotočamo se predvsem na kombinacijo t. i. Fenton-like reakcije in flokulacije, tudi v obratnem vrstnem redu. Železov sulfat preizkušamo kot koagulant in Zetag kot flokulant. Določamo vsebnost tenzidov in TLS v neobdelanih in obdelanih odvzetih vzorcih. Merimo količino nastalega blata. Ugotavljamo, da s povečanjem volumna dodanega koagulanta vedno ne dosežemo večje učinkovitosti čiščenja, temveč lahko povzročimo ravno obraten učinek. Rezultati kažejo, da je Jar-test glede na dane vzorce najprimernejši postopek za čiščenje odpadnih voda. Sledi mu dvofazna obdelava (Jar-test in UV/H2O2). Obratna kombinacija, kjer vzorce najprej obdelamo z naprednimi oksidacijskimi postopki in šele nato z Jar-testom, dajo slabše rezultate. Industrial wastewater is characterized by a very diverse chemical composition. High levels of hardly volatile lipophilic substances and anionic and nonionic surfactants are a major problem. The toxicity of industrial wastewater can be reduced through physico-chemical treatment methods such as coagulation, biological methods and advanced oxidation processes. The aim of the thesis was to determine the success of treatment of various industrial wastewaters with the coagulation/flocculation process and advanced oxidation processes under different conditions. A further goal was to analyze the efficiency, according to the first and second phase of treatment of different wastewaters, and to assume the best treatment combinations. We focused mainly on the combination of Fenton-like reactions and flocculations, including in reverse order. Iron sulfate was tested as a coagulant and Zetag as a flocculant. The content of surfactants and hardly volatile lipophilic substances in untreated and treated samples was determined. We also measured the amount of sludge that was formed during the processes. We have found that by increasing the volume of coagulant added, we do not always achieve higher cleaning efficiency but we can cause the exact opposite effect. The results show that the Jar test is the most suitable procedure for wastewater treatment according to the given samples. This is followed by a two-phase treatment (Jar test and UV/H2O2). The reverse combination, where the samples were first treated with advanced oxidation procedures and secondly with the Jar test, gave poorer results. koagulacija Jar-test industrijska odpadna voda napredni oksidacijski postopki blato coagulation Jar test industrial wastewater advanced oxidation processes sludge true true false [A.
