Abstract
Biokemijska potrošnja kisika (engl. biochemical oxygen demand, BOD) i kemijska potrošnja kisika (engl. chemical oxygen demand, COD) najčešći su parametri za praćenje organskog opterećenja otpadnih voda te za projektiranje, modeliranje i analizu rada uređaja za pročišćavanje otpadnih voda (UPOV). Međutim dugo vrijeme provedbe te loša preciznost i ponovljivost BOD analize i nastajanje toksičnih spojeva kroma i žive kod COD analize stvaraju potrebu za njihovom zamjenom. U ovome radu ispitana je zamjena COD i BOD5 s ukupnim organskim ugljikom (engl. total organic carbon, TOC) na 3 komunalna uređaja za pročišćavanje otpadnih voda, UPOV Karlovac, UPOV Koprivnica i UPOV Čakovec. Utvrđena je pozitivna linearna korelacija za COD i TOC u uzorcima ulazne otpadne vode i izlazne pročišćene vode te pozitivna linearna korelacija za BOD5 i TOC samo za uzorke ulazne otpadne vode.
Abstract (english)
Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) are the most common parameters for monitoring the organic load of wastewater and for designing, modeling and analyzing the operation of wastewater treatment plants (WWTP). However, the long implementation time and the poor precision and repeatability of BOD analysis and the formation of toxic compounds of chromium and mercury in COD analysis create the need for their replacement. In this paper, the replacement of COD and BOD5 with total organic carbon (TOC) at 3 municipal WWTP, WWTP Karlovac, WWTP Koprivnica and WWTP Čakovec, was examined. A positive linear correlation was found for COD and TOC in influent and effluent samples, and a positive linear correlation for BOD5 and TOC was only found in influent samples.
