Abstract

Tvari prisutne u otpadnoj vodi iz farmaceutske industrije mogu potencijalno biti štetne za okoliš. Biološka obrada otpadnih voda jedan je od najčešćih postupaka koji se koriste u obradi otpadnih voda. Kako bi se ocijenilo je li otpadna voda pogodna za biološku obradu, provode se testovi biorazgradnje. U ovom radu proveo se Zahn-Wellensov test biorazgradnje na dvije otpadne vode iz farmaceutske industrije (OV1 i OV2) te na otpadnoj vodi iz farmaceutske industrije nakon obrade s aktivnim ugljenom (OV2A). Tijekom provedbe testa praćeni su kemijska potrošnja kisika, ukupna suspendirana tvar, ukupni organski ugljik, ukupni dušik, koncentracija otopljenog kisika i pH-vrijednost. Rezultati pokazuju da je uklonjeno ukupnog organskog ugljika (TOC) 60 %, 0 % te 92 % za OV1, OV2 i OV2A.

Abstract (english)

Components that are present in wastewater from the pharmaceutical industry can potentially harm the environment. Biological treatment of the wastewaters is one of the most common methods used in the wastewater treatment. Biodegradability tests are conducted in order to assess whether wastewater is suitable for biological treatment. In this paper Zahn-Wellens biodegradation test was performed on two wastewaters from the pharmaceutical industry and on wastewater from the pharmaceutical industry after treatment with activated carbon. During the test procedure, monitoring of chemical oxygen demand, total organic carbon, mixed liquor suspended solids, total nitrogen, concentrations of dissolved oxygen and pH-level were performed. The results show elimination of total organic carbon (TOC) of 60 %, 0 % and 92 % for OV1, OV2 and OV2A, respectively.
