Abstract
Otpadne vode s velikom količinom hranjivih tvari (spojevi s dušikom i fosforom) koje dospjevaju u u prirodne vode, uzrokuju nagli rast bilja i fitoplanktona što dovodi do neuravnoženosti ekosustava. Dušik i ostala organska tvar uklanjaju se biološkom obradom voda. Bakterije uklanjaju dušik iz otpadnih voda procesom nitrifikacije i denitrifikacije. Nitrifikacija je biološki proces prevođenja otopljenog amonijaka do nitrata preko nitrita, gdje u prvoj fazi amonijak oksidirajuće bakterije prevode amonijak u nitrit, a u drugoj nitrit oksidirajuće bakterije prevode nitrit u nitrat. Denitrifikacija je biološka redukcija nitrata do plinovitog dušika pomoću fakultativno heterotrofnih bakterija. Učinkovito i ekonomično provođenje biološkog uklanjanja dušika postiže se izračunavanjem i predviđanjem bitnih karakteristika sustava pomoću poznatih matematičkih modela ustaljenog stanja.
Abstract (english)
Wastewater with a large amount of nutrients (nitrogen and phosphorus compounds) that is deposited in natural waters, causes rapid growth of plants and phytoplankton, which leads to ecosystem disequilibrium. Biological wastewater treatment removes nitrogen and other organic matter. Bacteriae remove nitrogen from wastewaters by processes of nitrification and denitrification. Nitrification is biological process where soluble ammonia is oxidized to nitrite and nitrate, where in first phase ammnonia oxidizing organisms convert ammonia to nitrite, and in second nitrite oxidizing organisms convert nitrite to nitrate. Denitrification use the biological reduction of nitrate to nitrogen gas by facultative heterotrophic bacteria. Calculating of important characteristics of wastewater treatment system with the help of well known steady state mathematical models enabels efficient and economical execution if biological nitrogen removal.
