Odstranjevanje stabilnega antibiotika gentamicin sulfata iz modelne odpadne vode z ozonacijo

Mislej, Leon (author), Žgajnar Gotvajn, Andreja (mentor)

Velik del farmacevtskih učinkovin po uporabi preide v odpadne vode, ki se čistijo v komunalnih čistilnih napravah, ki pa za njihovo učinkovito odstranjevanje niso ustrezne. Tako se farmacevtske učinkovine nato kopičijo v okolju, kjer lahko škodujejo organizmom in povzročajo še druge nezaželjene učinke. Zato se za njihovo odstranjevanje iščejo in razvijajo drugi postopki. Za zelo učinkovite so se izkazali napredni oksidacijski procesi. V okviru diplomske naloge smo se osredotočili na uporabo ozonacije kot enega izmed naprednih oksidacijski procesov za odstranitev široko uporabljenega in težko razgradljivega antibiotika gentamicin sulfata. Primerjali smo učinkovitost odstranjevanja antibiotika iz modelne in realne odpadne vode pri različnih pogojih ozonacije. Iz rezultatov poskusov je razvidno, da se gentamicin sulfat učinkovito razgradi, če izvajamo ozonacijo pri povišanem pH.

• Title: Removal of persistent antibiotic gentamicin sulphate from model wastewater by ozonation

Abstract

Through usage, a large part of pharmaceutical substances passes into wastewater, which is cleaned in municipal sewage treatment plants, which are not suitable for the effective removal of these substances. Thus, the pharmaceuticals then accumulate in the environment, where they can damage organisms and cause other unwanted effects. Therefore, new procedures are being investigated for the removal of these substances in wastewater. Advanced oxidation processes have proven to be very effective. In this thesis we focused on the use of ozonation for the removal of the widely used and difficult to degrade antibiotic gentamicin sulfate. We compared the efficiency of antibiotic removal from model and real wastewater at different ozonation parameters. The results of the experiments show that gentamicin sulfate is efficiently removed by ozonation at higher pH levels.
