Abstract
U ovom radu istražena je nitrifikacija te učinak omjera C/NNH4-N na brzinu procesa. Opterećenje organskim sastojcima istraženo je za omjere (i) C/NNH4-N 1; 116 mg KPK/L; 63,8 mg NH4 –N/L; 9,7 mg NO3-N/L; 1,8 mg NO2-N/L; (ii) C/NNH4-N 2; 240 mg KPK/l; 63,2 mg NH4-N/L; 7,6 mg NO3-N/L; 0,2 mg NO2-N/L; (iii) C/NNH4-N 3; 370 mg KPK/L; 63,8 mh NH4-N/L; 10,8 mg NO3-N/L; 2,4 NO2-N/L; (iv) C/NNH4-N 4; 462 mg KPK/L; 58,8 mg KPK/L; 10 mg NO3-N/L; 2 mg NO2-N/L; (v) C/NNH4-N 5; 659 mg KPK/L; 60 mg NH4-N/L; 6,5 mg NO3-N/L; 0,6 mg NO2-N/L. Pokazano je da je najveći gubitak N od 37,8% ostvaren pri omjeru C/NNH4-N 5 što odgovara omjeru KPK/NNH4-N 10,9. Najveća redukcija KPK od 91,2% postignuta je pri omjeru C/NNH4-N što odgovara omjeru KPK/NNH4-N 10,9. pH i količina utrošenog kisika pokazali su se kao značajni pokazatelji završetka procesa nitrifikacije prilikom čega dolazi do naglog porasta vrijednosti pH i DO.
Abstract (english)
This paper explored the effect of nitrification and the ratio of C/NNH4-N on speed of the process. Load organic compounds have been explored for the ratio (i) C/NNH4-N 1; 116 mg KPK/L; 63,8 mg NH4 –N/L; 9,7 mg NO3-N/L; 1,8 mg NO2-N/L; (ii) C/NNH4-N 2; 240 mg KPK/L; 63,2 mg NH4-N/L; 7,6 mg NO3-N/L; 0,2 mg NO2-N/L; (iii) C/NNH4-N 3; 370 mg KPK/L; 63,8 mh NH4-N/L; 10,8 mg NO3-N/L; 2,4 NO2-N/L; (iv) C/NNH4-N 4; 462 mg KPK/L; 58,8 mg KPK/L; 10 mg NO3-N/L; 2 mg NO2-N/L; (v) C/NNH4-N 5; 659 mg KPK/L; 60 mg NH4-N/L; 6,5 mg NO3-N/L; 0,6 mg NO2-N/L. It has been shown that the greatest loss of N by 37,8% was achieved at a ratio of C/NNH4-N 5 corresponding to the ratio of COD/NNH4-N 10,9. The greatest reduction of COD of 91,2% was achieved at a ratio of C/NNH4-N corresponding to the ratio of COD/NNH4-N 10,9. pH and oxygen consumption have proven to be significant indicators of completing the process of nitrification during which a sudden increase in pH and DO is occurring.
