Abstract
U ovom radu provedena je oksigenacija supstrata (vodovodna voda, komunalna otpadna voda s aktivnim muljem) primjenom jednog i dva difuzora. Napravljen je sedimentacijski test taloženja aktivnog mulja te mikrobiološka analiza. Da bi se biološka aerobna obrada otpadne vode mogla provesti, potrebno je u reaktoru postići uvjete zasićenosti kisikom. Kritična razina zasićenosti je 2 mg O 2 /L, optimalna 4 mg O 2 /L, a maksimalna predstavlja količinu kisika ovisno o supstratu. Rezultati oksigenacije ispitivanih supstrata pokazali su da se u kratkom vremenu postiže kritična, a potom i optimalna razina zasićenosti kisikom. Ovo ukazuje na primjenjivost biološke obrade komunalne otpadne vode s aktivnim muljem primjenom difuzora pri čemu se učinkovitost od 86,58% izražena preko KPK pokazatelja postiže za 5,5 sati primjenom jednog difuzora.
Abstract (english)
In this paper, oxygenation of the substrate (tap water, municipal wastewater with activated sludge) was performed by using one and two diffusers. A sedimentation test of activated sludge and microbiological analysis was performed. To perform biological aerobic wastewater treatment, it is necessary to achieve oxygen saturation conditions in the reactor. The critical saturation level is 2 mg O 2 /L, the optimal 4 mg O 2 /L, and the maximum amount of dissolved oxygen depends on the substrate. The results of oxygenation of the tested substrates showed that a critical and then optimal level of oxygen saturation is achieved in a short time. This indicates the applicability of the biological treatment of municipal wastewater with activated sludge using a diffuser, where the efficiency of 86.58% expressed through the COD indicator is achieved after 5.5 hours by using a single diffuser.
