Abstract

U ovom radu istražena je razgradnja otpadne vode iz procesa proizvodnje šećera. Anaerobna razgradnja otpadne vode šećerane je provedena diskontinuiranim i kontinuiranim pokusima pomoću anaerobnog mulja. Postignuto je 89-92% uklanjanje organskih sastojaka. Postupkom nitrifikacije sa predenitrifikacijom pomoću mikrobne kulture nitrifikanata i denitrifikanata razgradnjom anaerobno obrađene otpadne vode je postignuto 82-85% uklanjanje sastojaka s dušikom i 94% uklanjanje organskih sastojaka. U istraživanju denitrifikacijskog potencijala otpadne vode od pranja šećerne repe određen je minimalni omjer KPK/N = 8 za postizanje potpune redukcije nitrata. U SB reaktoru se primjenom mikrobne kulture nitrifikanata i denitrifikanata postiže potpuno uklanjanje organskih sastojaka i sastojaka s dušikom iz otpadnih voda od pranja šećerne repe i kondenzata.

Abstract (english)

In this work the degradation of wastewater from sugar production industry was investigated. Anaerobic digestion of sugar industry wastewater was carried out in discontinuous and continuous experiments with anaerobic sludge. It was achieved 89-92% removal of organic compounds. By nitrification with predenitrification using microbial culture 82-85% removal of nitrogen and 94% removal of organic compounds from anaerobically treated sugar industry wastewater was achieved Denitrification potential of sugar beet wash wastewater was determined by a minimum ratio of COD/N = 8 for complete reduction of nitrate. In SB reactor by using microbial culture complete removal of the organic compounds and nitrogen from sugar beet wash wastewater and condensate was achieved.
