Abstract
U ovom radu je provedena fizikalno-kemijska karakterizacija procjedne vode s odlagališta otpada Bikarac te njena obrada primjenom vapna, aeracije i Fenton procesa. Rezultati su pokazali da nakon obrade vapnom i aeracije vrijednosti pokazatelja pH i KPK su iznad MDK vrijednosti propisanih Pravilnikom te se obrađena procjedna voda ne može ispustiti u sustav javne odvodnje. Ispitan je utjecaj pH, koncentracije Fe 2+ iona i H 2 O 2 , molarnog koncentracijskog omjera Fe 2+ :H 2 O 2 te vremena kontakta na smanjenje KPK vrijednosti primjenom Fenton procesa. Najučinkovitije smanjenje KPK primjenom Fenton procesa u iznosu od 40% postignuto je pri optimalnim uvjetima procesa: pH = 3 i molarnom koncentracijskom omjeru Fe 2+ :H 2 O 2 =1:20 te koncentracije Fe 2+ od 9 mg/L. Kinetički rezultati su ukazali da je kinetika razgradnje organskih tvari iz procjedne vode iznimno složena. Primjenom Fenton procesa postigli su se uvjeti za ispust obrađene procjedne vode u površinske vode.
Abstract (english)
In this paper, the physico-chemical characterization of leachate from the Bikarac landfill and its treatment using lime, aeration and Fenton process was performed. The results showed that by applying lime and aeration the values of pH and COD are above the permissible limits prescribed by the Croatian legislative and treated leachate cannot be discharged into the public system. The influence of pH, concentration of Fe 2+ ions and H 2 O 2 , molar concentration ratio of Fe 2+ :H 2 O 2 and contact time on the decreasing of COD values using the Fenton process was also investigated. The most effective decreasing of COD using Fenton-like process in the amount of 40% was achieved under optimal process conditions: pH=3 and molar concentration ratio Fe 2+ :H 2 O 2 =1:20 and concentration of Fe 2+ was 9 mg/L. The kinetic results indicated that the kinetics of decomposition of organic matter from leachate is extremely complex. By applying the Fenton process, the conditions for the discharge of treated leachate into surface waters were achieved.
