Abstract
U ovom radu istražena je učinkovitost uklanjanja organskih sastojaka i nutrijenata iz sintetske otpadne vode koja svojim sastavom oponaša otpadnu vodu kućanstva pomoću aerobnih granula. Istražen je učinak koncentracije otopljenog kisika u rasponu 0ˉ¹ mg Lˉ¹ i 1-2 mg Lˉ¹ i učinak omjera kemijske potrošnje kisika i dušika KPK/N 5 i 11,5. Najveća učinkovitost uklanjanja KPK, NH4-N, PO4-P i ukupni dušik (TN, engl. Total Nitrogen) je postignuta u kombinaciji otopljenog kisika 1-2 mg Lˉ¹ i omjera KPK/N 11,5, pri čemu je postignuto 85 %, 88 %, 72 % i 83 % uklanjanje KPK, NH4-N, PO4-P i TN. Smanjenje omjera KPK/N, i/ili smanjenje koncentracije otopljenog kisika narušava učinkovitost uklanjanja organskih sastojaka i nutrijenata, a smanjenje otopljenog kisika snažnije narušava učinkovitost uklanjanja
Abstract (english)
In this study, the efficiency organics and nutrient removal from synthetic wastewater, whose composition mimics the municipal wastewater by means of aerobic granular sludge, was investigated. The effect of dissolved oxygen concentration in the range of 0-1 mg Lˉ¹ and 1-2 mg Lˉ¹ and the effect of chemical oxygen demand and nitrogen COD/N ratio 5 and 11.5 were investigated. The highest removal efficiency of COD, NH4-N, PO4-P and TN (engl. Total Nitrogen) was achieved in the combination of dissolved oxygen 1-2 mg Lˉ¹ and COD/N ratio 11.5, achieving 85 %, 88 %, 72 % and 83 % removal of COD, NH4-N, PO4-P and TN. Decreasing the COD/N ratio, and/or reducing the dissolved oxygen concentration deteriorates the efficiency of removal of organics and nutrients, and the reduction of the dissolved oxygen more severely impairs the removal efficiency.
