Odstranjevanje dušika iz komunalne odpadne vode : magistrsko delo /
Preučevali smo odstranjevanje dušika iz odpadne vode, ki vsebuje fekalne in industrijske vode ter gnojevko iz prašičje farme. Obdelava vode je potekala s procesi nitrifikacije in denitrifikacije. Preskusi so potekali v dveh 6L reaktorjih. Preučevali smo nitrifikacijo nitrata in nitrita do aminija v...

| 520 | |a Preučevali smo odstranjevanje dušika iz odpadne vode, ki vsebuje fekalne in industrijske vode ter gnojevko iz prašičje farme. Obdelava vode je potekala s procesi nitrifikacije in denitrifikacije. Preskusi so potekali v dveh 6L reaktorjih. Preučevali smo nitrifikacijo nitrata in nitrita do aminija v reaktorjih, ki sta delovala kontinuirno in šaržno. Kot vir ogljika smo uporabili metanol in etanol za denitrifikacijske preskuse v laboratoriju. Ugotovili smo večjo učinkovitost šaržnega sistema, in sicer z modelom ena ura prezračevanja in ena ura brez prezračevanja. Pri denitrifikaciji je bila najbolj uspešna uporaba etanola v razmerju 1:2. Preučevali smo tudi odstranjevanje fosfata. Ugotovili smo, da se fosfat najbolje obarja pri 25°C, 50 mg/L kalcija in brez prisotnega hidrogen karbonatnega iona. | ||
| 520 | |a Nitrogen removal from waste water with pig slurry, domestic waste and industrial waste was studied. Treatment method was based upon processes of biological nitrification and denitrification. Experiments were performed in two 6L reactors. Nitrification of ammonia to nitrate and nitrite was studied in reactor operated as batch and continuous system. Metanol and ethanol were used as carbon source for denitrification of oxidized mineral nitrogen in batch system in laboratory. The maximum efficiency betweenbatch and continuoussystem was established using batch system with one hour of aeration and one hour without aeration. The maximum efficiency of the denitrification proces was established using ethanol as carbon source at C:N ratio of 2:1. The removal of phosphate was analyzed. The maximum efficiency of the phosphate removal was established by 25°C, 50mg/L calcium and without carbonate ion. | ||
