Obdelava tekočih odpadkov z elektrokoagulacijo

Tekavc, Anže (author), Žgajnar Gotvajn, Andreja (mentor)

Tekoči odpadki, kot so z oljem onesnažena voda iz naprav za ločevanje olja in vode, emulzije, tiskarske barve in odpadne vodne raztopine, niso primerni za izpust v kanalizacijo in se morajo pred izpustom ustrezno predčistiti. V Sloveniji letno nastane približno 90 tisoč ton tekočih odpadkov, ki niso primerni za izpust v kanalizacijski sistem in se odstranjujejo po postopku fizikalno-kemijske obdelave. V nalogi smo predstavili učinkovitost obdelave tekočih odpadkov s postopkom elektrokoagulacije. Preizkuse smo izvedli na različnih tekočih odpadkih in ovrednotili učinek čiščenja po posameznih parametrih.

• Title: Evaluation of liquid waste treatment by electrocoagulation

Abstract

Liquid wastes such as oil-contaminated water from oil-water separators, emulsions, printing inks, aqueous waste solutions cannot be discharged directly into the sewer system and require pretreatment. In Slovenia, about 90 thousand tons of liquid waste are generated annually, which can be disposed after using physical-chemical treatment process. In this diploma thesis we evaluate the efficiency of electrocoagulation for treating various industrial liquid wastes. The tests were carried out on different liquid wastes and the treatment efficiency was evaluated according to individual parameters.
