Abstract:Elektrokoagulacija je metoda čiščenja odpadnih voda, ki za to uporablja elektrokemično celico. V preteklosti so že potekale raziskave za morebitno uporabo te metode za čiščenje odpadnih voda, vendar so jo konvencionalne metode izpodrinile. V zadnjih desetletjih, ko poteka intenzivno iskanje alternativnih metod čiščenja odpadnih voda, pa ponovno narašča število raziskav, povezanih z uporabo elektrokoagulacije, saj se kaže kot enostavna in cenovno dostopna metoda za čiščenje odpadnih vod. Namen diplomske naloge je bil preveriti učinkovitost elektrokoagulacije pri čiščenju oljno-vodnih emulzij ter določiti optimalne pogoje za njen potek. Ugotovili smo, da začetna pH vrednost emulzije, razdalja med elektrodama in uporabljen električni tok odločilno vplivajo na učinkovitost elektrokoagulacije. Velik vpliv ima tudi kemijska čistost elektrod. Vrednost KPK industrijskih emulzij se je pri optimalnih pogojih znižal od 57 % do 69 % Elektrokoagulacija je tako učinkovita pri čiščenju oljno-vodnih emulzij, vendar pa je potrebna njihova predobdelava.

Abstract:Electrocoagulation is a method for waste water treatment using electrochemical cell. It has been tested as a potentially useful method in the past but has been superseded by conventional methods. In recent decades search for alternative waste water treatment went on, therefore a lot of research is dedicated to electrocoagulation which seems to be simple and cost effective method for wastewater treatment. The subject of this diploma thesis was to check the effectiveness of electrocoagulation of oil-water emulsions, and to determine optimal parameters for the process. It was found that the pH of the emulsion, distance between electrodes, and the electrical current applied have major impact on method's effectiveness. Chemical purity of electrodes has a big impact as well. The COD values of industrial emulsions at optimal conditions decreased in the range from 57 % to 69 %. Electrocoagulation is effective in treating oil-water emulsions but certain pretreatment is required.
Keywords:electrocoagulation, oil-water emulsion, COD
