Abstract

Zaradi rasti svetovnega prebivalstva je vpliv na okolje vedno večji, narašča pa tudi potreba po pitni vodi. Obenem narašča tudi število industrijskih procesov in obratov, od katerih mnogi onesnažujejo vire pitne vode. S tem problemom se množično srečujejo v manj razvitih državah, kjer je industrija manj tehnološko razvita ter zakonodaja neustrezna, vendar pa se vse preveč pogosto pojavlja tudi povsod drugod. Med pogosta nevarna onesnaževala, prisotna v vodnih virih, sodijo tudi fenoli. Slednje lahko najdemo v odpadnih vodah številnih industrij, kot so na primer farmacevtska, petrokemična in tekstilna industrija, proizvodnja koksa, smol, barv in še mnoge druge. Fenoli lahko resno vplivajo na zdravje živih bitji in seveda s tem tudi na ljudi. Ob stiku lahko pride do draženja oči, kože ter sluznice. Daljša izpostavljenost lahko vodi do motenj v dihanju, bolečin v mišicah, kome in celo do zastoja dihanja v kolikor smo izpostavljeni smrtnim odmerkom. Ob daljšem stiku s preveliko koncentracijo fenolov se lahko pojavijo motnje centralnega živčnega sistema, jeter, ledvic in prebavil. Zaradi njihove strupenosti je torej pomembno, da se jih v dovoljšnji meri odstrani iz vodnega cikla. Z leti so se tako razvile raznovrstne metode za bolj ali manj učinkovito odstranjevanje fenolov. Glavne med njimi bom podrobneje opisal v diplomski nalogi. Namen naloge je pregled dostopne literature s področja odstranjevanja fenola in njegovih spojin iz odpadnih vod, s poudarkom na industrijskih odpadnih vodah. Diplomska naloga bo zajemala tudi podrobnejši opis lastnosti fenola in opis ter primerjavo različnih tehnik odstranjevanja med seboj.

Secondary title: Removal of phenols and their compounds from industrial waste water
Secondary abstract: Because of the growing world population, the impact on the environment is increasing as well as the need for drinking water. At the same time, the number of industrial plants and processes, that pollute the drinking water is growing. Many less developed countries where the industry is less technologically advanced and the legislation is inadequate are facing this problem, but it is all too common everywhere else as well. Phenols are among the common hazardous pollutants found in water sources. The latter can be found in the wastewater of many industries, such as pharmaceuticals, petrochemicals, textiles, coke, resins, paints, and many others. Phenol and its compounds can seriously affect the health of various living things and with that of course, humans. Contact can cause irritation to the eyes, skin, and mucous membranes. Prolonged exposure can lead to breathing problems, muscle pain, coma and even respiratory arrest if exposed to lethal doses. Prolonged exposure to excessive concentrations of phenols can also cause central nervous system, liver, kidney, and gastrointestinal problems. Because of their toxicity, it is therefore important to remove them from the water cycle to a sufficient extent. Over the years, various methods have been developed to remove phenols more or less efficiently, the main ones of which I will describe in more detail in my thesis. The aim of this thesis is to review the available literature in the field of removal of phenols and their compounds from wastewater, with a focus on industrial wastewater. The thesis will also include a more detailed description of the properties of phenol and a description and comparison of the different removal techniques.
