Abstract

V okviru diplomske naloge smo čistili odpadne oljno vodne emulzije (OOE) in odpadne oljno vodne emulzije, ki so bile predčiščene z ultrafiltracijo ali z uparjanjem. Cilj naloge je bil odstraniti organske snovi iz emulzij do take mere, da bo kakovost pod predpisano mejno vrednostjo, v skladu z veljavno slovensko zakonodajo. Vzorce smo čistili z adsorpcijo na aktivnem oglju (PAC). Pri čiščenju emulzij, ki niso bile predhodno predčiščene, nismo dosegli želenega znižanja KPK, saj gre za kompleksne emulzije, katerih čiščenje je težavno in zahteva kombinacijo večih metod. Pri adsorpciji predhodno ultrafiltriranih emulzij prav tako nismo dosegli želene mejne vrednosti. Rezultati diplomskega dela so pokazali, da lahko samo v odpadnih emulzijah, ki so bile obdelane z uparjanjem pod določenimi pogoji, z adsorpcijo na aktivnem oglju znižamo KPK vrednost pod 120 mg/L O2.

Secondary title:	COD removal from pre-treated emulsions using adsorption
Secondary abstract:	The subject of these thesis was cleaning of wasted oil-in-water emulsions (OOE) and wasted oil-water emulsions, which were pre-treated with ultrafiltration or evaporation. The aim of the thesis was removal of organic compounds from emulsions in order to reach water quality in accordance with slovenian legislation for water release into the environment. The samples of emulsions where cleaned with adsorption on activated carbon(PAC). If the emulisons were not pre-treated, we did not achieve the removal of COD below the limit value, because these emulsions are complex and cleaning of such emuslions requires combination of more different methods. We also did not achieve the limit values if adsorption followed ultrafiltration of emulsions. If the combination of evaporation and adsorption of emulsions was chosen, we could remove COD under 120 mg/L O2.
