Abstract
U radu je dobivena simulirana procjedna voda komine masline kontinuiranim ispiranjem komine destiliranom vodom tijekom tri dana. U uzorku su određeni pokazatelji kakvoće vode (pH vrijednost, mutnoća, električna provodnost, KPK, BPK 5 , dušik po Kjeldahlu) koji su ukazali da prema zakonskim propisima ovakva voda nije pogodna za ispust u površinske vode ni u sustav javne odvodnje. Aeracijom procjedne vode vrijednost KPK se smanjuje za 13%, a BPK 5 za 44% čime voda zadovoljava uvjete za ispust u sustav javne odvodnje, ali ne i u površinske vode. Primjenom Fenton sličnog procesa pri različitim pH vrijednostima, različitim koncentracijama Fe 3+ iona i različitim omjerima množinskih koncentracija Fe 3+ : H 2 O 2 utvrđeno je da se najbolji učinak smanjenja KPK od 19% postiže pri minimalnoj koncentraciji Fe 3+ iona od 9 mg/L, pH vrijednosti od 3,03 i pri omjeru množinskih koncentracija (Fe 3+ : H 2 O 2 ) od 1:30. Primjenom aeracije i Fenton sličnog procesa KPK vrijednost se ukupno smanjuje za 32% i kao takva ne zadovoljava uvjete za ispust u površinske vode, ali zadovoljava uvjete za ispust u sustav javne odvodnje.
Abstract (english)
The simulated leachate of olive pomace is obtained by continuous leaching of the olive pomace using destilled water during three days. Water quality parameters (pH value, turbidity, electrical conductivity, COD, BOD 5 , Kjeldahl nitrogen) were determined in the sample and according to legislative, leachate is not suitable for discharge into surface water or into the public sewage system. Aeration of wastewater reduces COD values by 13% and BOD 5 by 44%, which means that the water meets the conditions for discharge into public drainage system, but not into surface waters. Using a Fenton like process at different pH values, different mass concentrations of Fe 3+ ions and different molar concentration ratios of Fe 3+ : H 2 O 2 , it was found that the best removal efficiency of 19% is achieved at a minimum concentration of Fe 3+ ions of 9 mg/L, pH value of 3,03 and at a molar concentration ratio (Fe 3+ : H 2 O 2 ) of 1:30. Summary, aeration and Fenton like process reduced the COD value up to 32%, but treated leachate does not meet the requirements for discharge into surface waters, where meets the requirements for discharge into the public sewage system
